348-5430 Multi-Tool Gp

The Multi-Tool (1) is a handheld tool that contains a software operating system and diagnostic programs (applications). The diagnostic applications are accessed by using the menu-driven display of the Multi-Tool and the keys on the front of the tool.

The DIM (2) connects to the back of the Multi-Tool and is used to connect test tools (cables and sensors). The DIM is the interface between the test tools and the internal software applications of the Multi-Tool.

The power adapters and cords supply power to the tool by using either of the following.

• Rechargeable internal battery pack

• DC power from the battery of the equipment or vehicle

• AC power from an outlet.

4 AC power cords are included for international use.

When the Multi-Tool is turned on, the main screen is the Application Manager screen. The Application Manager Screen is a menu screen that lists the programs (applications) available in the Multi-Tool. This screen is used to select and start each application.

The applications include the following:

• Blowby/Airflow Indicator

• Digital Thermometer

• Electronic Position Indicator

• Engine Timing Indicator

• Fuel Flow

• Multi Tach II

• Signal Generator

To access an application, the application must be activated using a software license card. Activated applications appear at the top of the menu and are black-colored. Unactivated applications appear at the bottom of the menu and are gray-colored. After an application is activated, the application is permanently accessible. For details, see Activate Applications in the SETUP section of this manual.

Electronic Position Indicator Application

Overview

Note: For service information, refer to the Caterpillar Service Information System and to the Special Instruction, SEHS8623 - Using the 8T-1000 Electronic Position Indicator Gp .

Illustration 57	g02159613
(1) Electronic Position Indicator Application.

The Electronic Position Indicator application is used with the 285-0898 Electronic Position Indicator Gp . The indicator functions as a precision measuring gauge for reading both static and dynamic measurements.

Depending on selections made with the function keys, the application displays the following readings:

• Either positive (+) or negative (-) digital readings, as either inches or millimeters, for a selected channel.

The digital readings include actual, maximum, minimum, and difference readings.

The application also displays a graph of the actual readings. The application has functions for changing sampling rate and setting a "zero" point to set the actual reading to zero (0) at a selected point on a probe.

The application can be used to monitor the position of the fuel injection pump rack on an operating engine. The application test the fuel setting of the engine with a load.

The Electronic Position Indicator application replaces mechanical dial indicators. The application has a special electronic filter that stabilizes dynamic readings. Therefore, the application can be used for tests that may fail when using mechanical dial indicators, such as tests with rapidly changing dynamic readings.

In addition, with the 8T-1002 Pickup As (25.4-MM) (part of the 285-0898 Electronic Position Indicator Gp ) installed on a test stand, the Multi-Tool can be used as a permanent installation for testing and calibrating fuel injection pumps.

Maintain adequate clearance around moving components and/or belts during testing. Moving components and/or belts can catch test equipment, loose clothing, or body parts, and cause damage, personal injury, or death.

Electronic Position Indicator Basic Procedures

Probe Assembly

The 8T-1002 Pickup As (25.4-MM) in the 285-0898 Electronic Position Indicator Gp , is the standard probe for the Electronic Position Indicator application. The probe mounts in the same manner as a mechanical dial indicator and uses many of the same mounting fixtures

Illustration 61	g02159998
Position Indicator Probe Assembly. (1) 8T-1002 Pickup As (25.4-MM). (2) Probe Shaft. (3) Contact Point.

The position indicator probe (1) has a standard 9.52 mm (0.375 inch) diameter mounting stem. Always use this stem to mount the probe. Install a correct length contact point (3) in the probe shaft (2) and finger tighten.

Note: The probe shaft (2) has AGD 4-48 internal threads that accept most standard dial indicator tips, such as those in 6V-6042 Indicator Point Gp .

Connect the 8T-1002 Pickup As (25.4-MM) to a channel connector on the Multi-Tool DIM. If necessary, use the 6V-2198 Cable As .

Note: When removing a contact point (tip) from the probe shaft, if a clamp is required to keep the shaft from rotating, protect the shaft with a cloth and use extreme care not to scratch the shaft.

Note: Do not submerge the probe in any liquid or place the probe in the direct spray of any liquid. The probe is not sealed. If fluid gets inside the probe case, fluid can affect the operation or accuracy of the probe.

Note: Keep the probe shaft clean- dirt on the shaft can enter the shaft bearing and keep the shaft from operating freely. Wipe the probe shaft with a clean, soft cloth and apply a small amount of thin lubricating oil.

Measuring Values

Maintain adequate clearance around moving components and/or belts during testing. Moving components and/or belts can catch test equipment, loose clothing, or body parts, and cause damage, personal injury, or death.

1. Assemble the probe as described in the previous column.

2. Make the initial Multi-Tool settings by using the function keys.

3. Position the probe at the testing location.

4. The Multi-Tool position reading displays the distance the probe shaft has moved from the electrical zero point.
   • If NORM RATE is selected, a new reading is taken three times a second.

   • If SLOW RATE is selected, a new reading is taken once every second. The slow rate helps to stabilize the readings when taking rapidly changing dynamic readings.

Measuring Deviation

1. Use the steps in the previous section to set up the probe and Multi-Tool.

2. Set the probe to display 0.00 at the zero reference point of the part or position to be measured. Use the More function key, Zero option.

3. Move the probe to the measurement point on the part. The Multi-Tool displays the reading of the point being measured.

4. Press the Clear ( F2) function key to reset the readings.

5. The Max (1) and Min (2) readings display the reading of the point measured in Step 3 and the DIFF (3) reading displays 0.00.

Engine Timing Indicator Basic Procedures

Note: For complete service instructions, refer to the Caterpillar Service Information System and to theSpecial Instruction, SEHS8580, "Service Information and Use of 8T-5300 Engine Timing Indicator Group"

Maintain adequate clearance around moving components and/or belts during testing. Moving components and/or belts can catch test equipment, loose clothing, or body parts, and cause damage, personal injury, or death.

Diesel Fuel System Connection

When installing the 8T-5301 Diesel Engine Timing Adapter Gp , a fuel injection transducer T-adapter must be installed in the injection line at the fuel pump to keep the fuel lines from moving. With the transducer tee installed, the injection line will move only about 8 mm (0.3 inch), which will keep movement of fuel lines to a minimum.

Note: Do not use the 6V-4950 Speed Pickup with the Multi-Tool. The speed pickup is not designed for this tool.

DO not expose the Multi-Toll to liquids. Liquids cas enter the tool and cause damage. Flammable liquids cas cause as explosion, resulting in serious injury.

Static Timing

Most current production Caterpillar diesel engines are equipped with a timing pin hole in the flywheel housing and a corresponding hole in the flywheel. When the two holes are aligned, the piston for the number 1 cylinder is at the top center (TC) position. For static timing, when the flywheel housing and flywheel holes are aligned, a bolt can be inserted through the flywheel housing hole and threaded into the flywheel hole to lock the engine at the TC position.

Dynamic Timing

Note: To prevent inaccurate signals, make sure that the flywheel is free of any large nicks or holes between the time of fuel injection (or spark plug firing) and TC positioning.

For dynamic timing, the 285-0897 Engine Timing Pickup Gp is used with either the 6V-9060 Gas Engine Timing Group for testing a gas engine or the 8T-5301 Diesel Engine Timing Group for testing a diesel engine.

The MAG Engine Timing Group connects to the flywheel housing timing pin hole on a gas or diesel engine and to the audio jack on the back of the Multi-Tool DIM.

The 6V-9060 Gas Engine Timing Adapter Gp connects to the number one primary coil winding on a gas engine and to any of the four channels on the Multi-Tool.

The 8T-5301 Diesel Engine Timing Adapter Gp connects to the number one fuel injection pump on a diesel engine and to any of the four channels on the Multi-Tool.

To install the 285-0896 Adapter (5-PIN), install the correct transducer adapter in the flywheel housing timing pin hole and then connect the 6V-2197 Magnetic Transducer As (or optional transducer) to the adapter.

Connect the 5P-7362 Signal Cable As to the MAG transducer and to the audio jack on the back of the Multi-Tool DIM.

Note: Begin with a transducer/flywheel gap of 2.54 mm (0.10 inch).

Illustration 70	g02160962
DIM Audio Jack Location.

The magnetic transducer creates a magnetic field around the end of the transducer at the flywheel housing timing pin hole.

With the engine running, as the flywheel turns, the flywheel hole passes the end of the transducer, changes the magnetic field, and causes the transducer to send a top center (TC) signal to the Multi-Tool.

Depending on the Engine Timing Group being used ( 6V-9060 Gas Engine Timing Adapter Gp or the 8T-5301 Diesel Engine Timing Adapter Gp ), the Multi-Tool receives the spark (gas engines) or fuel injection (diesel engines) signal and then receives the TC signal from the MAG Transducer.

Note: The first signal from the magnetic transducer is considered the #1 cylinder TC signal.

The Multi-Tool Engine Timing Indicator application receives the fuel spark or injection signals (pulses) and converts the frequency to engine speed (RPM). The Multi-Tool Engine Timing Indicator measures the time between the number one cylinder spark or fuel injection signal and the TC signal. The Multi-Tool Engine Timing Indicator converts the signal to engine timing degrees (DEG), before top center (BTC).

Note: After the Multi-Tool receives the spark or fuel injection signal, Multi-Tool must receive the TC signal with in 60 degrees of flywheel rotation. If the Multi-Tool receives the TC signal after 60 degrees of flywheel rotation, the EngineTiming reading is incorrect and displays as a steady number between 60 and 90 degrees.

With the engine running, the Multi-Tool Engine Timing Indicator screen displays the RPM and Engine Timing readings. The MAG indicator displays either MAG: Adjust or MAG: OK as follows:

• MAG: Adjust means the distance between the transducer and the flywheel is not correct and the magnetic signal at the transducer is bad. Adjust the distance between the transducer and the flywheel.

Note: The transducer too far away from the flywheel causes a weak signal. Too close causes noise and false triggering.

Note: If the engine is not running, the word Adjust flashes.

Illustration 71	g02160966
(1) MAG: Adjust Indicator. (2) Log Data Point Message.

Note: Optionally, use the ENTER key to add data points to the graph, one at a time. Press the ENTER key for each point to add. Use the Clear function key to remove data points.

• MAG: OK means the distance between the transducer and the flywheel is correct and the magnetic signal at the transducer is good.

Illustration 72	g02160967

Make sure MAG: OK displays at both low and high engine speeds (RPMs). If necessary, adjust the distance between the transducer and the flywheel so that MAG: OK displays at all speeds.

Fuel Flow Application

Overview

Note: For service instructions, refer to the Caterpillar Service Information System and to the following Special Instructions, NEHS0776, "Using the Caterpillar 179-0710 Burn Rate Fuel Flow System",Special Instructions, NEHS0697, "Using the Caterpillar Fuel Com Fuel Flow Measurement System" and Special Instructions, NEHS0740, "Using the Caterpillar 168-7740 Fuel Com Fuel Flow System for 3600 Engines."

Illustration 73	g02161047
(1) Application Manager Screen, Fuel Flow Application.

The Fuel Flow application is used with the dual-turbine fuel flowmeters, cables in the 308-7271 Fuel Flow Checking Tool Group and hoses in the 308-7275 Hose Gp (DUAL TURBINE). To measure diesel engine fuel consumption and performance.

The Multi-Tool DIM provides for connecting up to four flowmeters using a one- or two-meter system: In a one-meter system, a flowmeter is connected to only the fuel supply line of an engine. (Or two engines using two flowmeters). In a two-meter system, a separate flowmeter is connected to each of the supply and return fuel lines of an engine. (Or two engines using four flowmeters).

The Fuel Flow application displays fuel flow data for either one or two engines. For each engine, the application displays the supply and return fuel flow rates and the calculated burn rate (temperature-corrected). For one-meter systems (measuring supply fuel flow only), the burn rate is equal to the supply fuel flow (because return fuel flow is zero). For two-meter systems, the burn rate is calculated as the supply fuel flow minus the return fuel flow.

Depending on selections made with the function keys the Fuel Flow application displays fuel flow readings and burn rates as SAE gallons per hour (GPH) or Metric liters per hour (LPH), displays totals or averages for fuel flow readings based on either run time or elapsed time and displays data for either one or two engines at a time. The application also displays a graph of the fuel burn rate/s and has a function for setting meter configurations for use of various meters.

Depending on selections made with the function keys the Fuel Flow application displays fuel flow readings and burn rates as SAE gallons per hour (GPH) or Metric liters per hour (LPH), displays totals or averages for fuel flow readings based on either run time or elapsed time and displays data for either one or two engines at a time

Panel (Engine) Labels (1)

Display the name of each panel. The names are factory-set at Engine 1 and Engine 2, but can be customized by using the More function key, Set Label option.

Data Rate (2)

Displays the data update rate set by using the More function key options: Norm Rate, Med Rate, and Slow Rate.

Previous/Next Indicator (3)

Arrows appear on the left and right side of the screen when the screen is set to display one engine panel at a time by using the Screen function key, 1-Engine option. The arrows indicate another panel is available for viewing. Use the LEFT and RIGHT Direction keys to display the other panel.

Burn Rate (4)

For each engine panel, displays the calculated burn rate and the measurement units. GPH (gallons per hour) indicates the More function key, SAE option is selected. LPH (liters per hour) indicates the More function key, Metric option is selected.

Note: The burn rate is calculated as the supply fuel flow minus the return fuel flow, temperature-corrected (see Item 7, ChannelFuel Flow Readings). When measuring only supply fuel flow, the burn rate equals the supply fuel flow (because the return fuel flow is zero).

Totals, Averages, Time (5)

When the screen is set to display one engine panel (using the Screen function key, 1-Engine option), displays engine fuel flow totals on the left side and averages on the right side based on settings made with the Engine 1 and Engine 2 function keys.

When the screen is set to display two engine panels (using the Screen function key, 2Engine option), displays either fuel flow totals or averages for each engine based on settings made with the Engine 1 and Engine 2 function keys.

See the Fuel Flow Function Keys section for more information. Fuel Flow Meter Screen: Two Engine Panel Display, SAE (GPH), Normal Rate.

Channel Labels (6)

Display the color and name of each channel. The names are factory-set as CH1:Return (yellow) and CH2:Supply (green) for Engine 2 and CH3:Return (blue) and CH4:Supply (red) for Engine 1, but can be customized by using the More function key, Set Label option.

Channel (Fuel Flow) Readings (7)

For each channel, displays the fuel flow reading or a red, flashing Under or Over Flow message.

An Under Flow message appears if the fuel flow reading is less than the minimum flow requirements for the flowmeter.

An Over Flow message appears if the fuel flow reading exceeds the capacity of the flowmeter.

If a channel does not have a flowmeter connected to the channel, a zero flow rate is assumed and the fuel flow reading displays as 0.0.

When using a single meter system (there is not a flowmeter attached to the return fuel line), the Return fuel flow reading must be 0.0 for the burn rate to calculate correctly.

Burn Rate Graph (8)

For each engine, displays the burn rate as a line graph with labels. The line graph can be reset by using the Screen function key, Clear option.

Fuel Flow Function Keys

The bottom of the Fuel Flow Meter screen displays four function keys that are used to control the Fuel Flow application.

Fuel Flow Tool Groups

The Fuel Flow application works with the flowmeters and cables in the 308-7271 Fuel Flow Checking Tool Group and the hoses in the 308-7275 Hose Gp (DUAL TURBINE) .

Optionally, the Fuel Flow application works with the 179-0700 Meter Gp and 179-0701 Computer (BURN RATE) or with the following discontinued fuel flowmeters: 154-8103 Fuel Meter Gp 154-8104 Fuel Meter Gp 168-7735 Fuel Meter Gp 168-7745 Fuel Meter Gp . See the Optional Fuel Flow Tools section.

308-7271 Fuel Flow Checking Tool Group

The 308-7273 Fuel Flow Checking Tool As (DUAL TURBINE) in the 308-7271 Fuel Flow Checking Tool Group have a wide flow range of 190 to 14762 liters per hour (50 to 3900 GPH). The tool groups are not sensitive to flow direction and do not require straightener tubes or accumulators. The tool groups also have built-in screens to protect the turbines from contamination in the fuel lines.

These flowmeters, which are powered by the Multi-Tool, output frequency signals that represent temperature-corrected volumetric flow. The Multi-Tool Fuel Flow application receives and interprets these frequency signals and displays both live readings and accumulated data.

Fuel Flow Basic Procedures

Maintain adequate clearance around moving components and/or belts during testing. Moving components and/or belts can catch test equipment, loose clothing, or body parts, and cause damage, personal injury, or death.

Diesel Fuel System Connection

Do not expose the Multi-Tool to liquids. Liquids can enter the tool and cause damage. Flammable liquids can cause an explosion, resulting in serious injury.

Always connect and leak-test all flowmeter and fuel line connections before beginning tests. An electric fuel pump could spray fuel from an open hose and cause fire or personal injury.

The Multi-Tool DIM provides for connecting up to four flowmeters using a one- or two-meter system:

• In a one-meter system, a flowmeter is connected to only the fuel supply line of an engine (or two engines using two flowmeters).

• In a two-meter system, a separate flowmeter is connected to each of the supply and return fuel lines of an engine (or two engines using four flowmeters). The following illustration shows the use of a two-meter system on one engine.

Illustration 84	g02177545
Engine Fuel Flow, Two-Meter System: (1) Dual-Turbine Flowmeter. (2) Diesel Fuel Tank. (3) Primary Filter. (4) Fuel Transfer Pump (5) Fuel Filter (6) Fuel Supply Line (7) Fuel Injection Pump. (8) Fuel Return Line. (Arrows indicate the direction of fuel flow.)

Use the correct hoses from the 308-7275 Hose Gp (DUAL TURBINE) to connect the 308-7273 Fuel Flow Checking Tool As (DUAL TURBINE) to the fuel lines.

Note: Flowmeters have protective end caps. Remove the end caps before use. After use, ALWAYS drain the fuel from the flowmeters and replace the end caps.

Note: Flowmeters do not require a rinse. NEVER use or rinse water in a flowmeter.

Note: DO NOT apply pressurized air though a flowmeter; damage to the turbine bearings may result.

Connect each flowmeter to the Multi-Tool DIM using a 308-7274 Cable As

• For a one-meter system, connect the flowmeter to either Channel 2 (green) or Channel 4 (red).

• For a two-meter system, connect the supply line flowmeter to Channel 2 (green) and the return line flowmeter to Channel 1 (yellow), or connect the supply line flowmeter to Channel 4 (red) and the return line flowmeter to Channel 3 (blue).

After making the connections, start the Multi- Tool Fuel Flow application and use the function keys to set up and control the fuel flow testing. See the Fuel Flow Function Keys section.

Two-Meter System Accuracy Formula

The accuracy / error of a two-meter system depends on the amount of fuel burned by the engine in relation to the amount of fuel returned to the tank. As the engine burns less fuel and more fuel returns to the tank, the accuracy decreases (error increases).

Use the following formula to calculate the worst-case error for any supply-to-return-rate reading combination:

[(0.5 x Supply Rate) + (0.5 × Return Rate)] ÷ Burn Rate = ± Percent of Reading Maximum Error

For example,

If:

Supply Rate = 2271Lph (600 gph),

Return Rate = 1135Lph (300gph), and

Burn Rate = 1135Lph (300gph)

Note: In this example the Burn Rate is 1/2 the Supply Rate.

Then:

((.5 × 600 gph) + (.5 × 300 gph)) ÷ 300 = ±1.5% of Reading Maximum Error,

or

300+ 150 (= 450)÷ 300 = ±1.5% of Reading Maximum Error.

Signal Generator Application

Overview

Note: For service information, refer to the Caterpillar Service Information System and to Special Instruction, SEHS8579, "Use of 8T-5200 Signal Generator/Counter Group".

Illustration 95	g02174116
(1) Signal Generator Application

The Signal Generator application works with the 285-0896 Adapter (5-PIN) and the 285-0899 Signal Generator Cable Gp (WITH COUNTER) to produce square waves that simulate the signal from a magnetic speed pickup. The simulated signal is helpful for troubleshooting transmission electronic control units. The application also functions as a frequency counter for pulsating AC or DC input.

When the Signal Generator application is selected from the Application Manager screen, the Signal Generator screen displays a menu for selecting a signal generator function.
