and/or
*PEGP7825-01 ... Core Acceptance Criteria (Short Block)
Reference Literature
Exchange of Parts
Each Remanufactured Engine is built to a reference engine arrangement, as given in the chart above.
No modification or parts exchange is necessary if the replacement engine arrangement is the same as the original engine arrangement.
Some modification or parts exchange may be necessary when the Remanufactured Engine reference arrangement number is different than the original engine arrangement number.
Use the reference literature when necessary to exchange parts between the original and new engine.
NOTE: Although some of the parts on the new engine may be different from those on the original engine, an exchange may NOT be necessary, depending upon the specific application.
In some installations it may be more advantageous to make minor modifications to the machine frame or engine mounting rails, rather than to exchange components between the Remanufactured Engine and the original engine.
Before installation of the Remanufactured Engine, make sure the flywheel housing, flywheel and vibration damper/crankshaft pulley are compatible with your application.
Each Remanufactured Engine is rated at a specific power rating at a specific rpm.
The Remanufactured Engine that is to be installed will not necessarily have the same kW (Hp)/rpm rating as the original engine that it is replacing.
The kW (Hp)/rpm rating setting(s) of the Remanufactured Engine can be adjusted to the same kW (Hp)/rpm rating as the original engine.
NOTE: Do NOT change/adjust any fuel setting(s) before referring to the:
- * FUEL SETTING INFORMATION LIBRARY ... and/or
- * FUEL SETTING AND RELATED INFORMATION microfiche.
For maximum life of the Caterpillar Remanufactured Engine, the following components MUST be inspected for reusability before installation:
Air Compressor
The engine oil is the source of lubrication and must be inspected for contamination as foreign material from a failure of the former engine can decrease engine life.
Worn air compressors can be a source of high oil consumption by pumping oil into the engine air intake pipe, or the vehicle's air tanks.
Air Cleaner
The engine air inlet system should be inspected and components replaced if worn:
- * Install a new air filter element.
- * Install all hoses and clamps as necessary.
- * Inspect air inlet piping and connections for leaks.
- * Repair or replace as required.
- * Install all hoses and clamps as necessary.
Radiator
- * Clean and/or flush as required.
- * Inspect for exterior fin damage.
- * Inspect for leaks.
- * Install new hoses and clamps.
- * Inspect for exterior fin damage.
Viscous Fan Clutch (If equipped)
If the engine is equipped with a viscous fan clutch:
- * Inspect for leaks.
- * Check fan speed to be sure of proper operation.
Water Separator (Recommended)
Some of the Remanufactured Engines that come from the factory may NOT have a factory installed water separator.
However, it is a Caterpillar recommendation that a water separator be installed.
Inspect the original water separator for reusability or replace as needed.
If the original is used, refer to the Operation & Maintenance Manual before installation.
Oil Pan
Compare the oil pan configuration on the Remanufactured Engine with that of the original engine.
If they are different:
- * The oil pan from the remanufactured engine must be changed to match the original engine.
- * If the oil pan is changed:
- * The oil pump suction bell must be changed to fit the oil pan sump location.
- * The dipstick and guide tube may also need to be changed and/or recalibrated for a particular application.
- * If the oil pan is changed:
Fuel System
Compare power ratings and rpm settings on the engine information plate of the Remanufactured Engine to the information with the same settings of the original engine.
If the settings are different:
- * Some fuel system adjustment(s) must be made.
If a part(s) change or fuel setting is required, for a specific engine application, refer to the:
- * Fuel Setting Information Library ... and/or
- * Fuel Setting and Related Information Library
- * Parts Book1
- * Service Manual
- * Fuel Setting and Related Information Library
1The engine arrangement number, stamped on the 9L6531 Engine Information Plate, can also be used to reference the Parts Book for the parts required within a specific engine arrangement.
NOTE: Whenever engines are reset to new specifications, a 4W5140 Plate stamped with the NEW specifications, MUST be installed over a portion of the original engine's 9L6531 Engine Information Plate.

Flywheel
The original engine flywheel must be removed, cleaned and inspected for reusability.
If the original flywheel can not be used again, refer to the specific Parts Book to find the correct part number flywheel to use.
Install the flywheel on the Remanufactured Engine and tighten the bolts to the correct torque.
Refer to the Service Manual for the torque specifications.
NOTICE |
---|
The 0R3687 Remanufactured Engine features a 3 ring piston design, a different damper and a DIFFERENT flywheel than the original engine with the 2 ring piston design. The 0R3687 Remanufactured Engine is equipped with the new damper only. The reuse of the original flywheel, installed onto a 0R3687 Remanufactured Engine, can cause vibrational problems. While general experience says any vibration problems should be minimal, the reuse of the original should be the customers decision. Caterpillar does NOT assume any responsibility for ANY subsequent damage and/or repairs traceable to the reuse of the original flywheel or similar design flywheel installed onto a 0R3687 Remanufactured Engine. |
Refer to Truck Engine News ... June 1989, for a listing of the part numbers of flywheels used with the 3 ring design piston.
Governor (Accelerator) Control
Remove the governor (accelerator) control from the original and install onto the Remanufactured Engine.
Refer to the Service Manual for correct adjustment.
Remove any remaining componets, alternator, starter motor etc., from the original engine and inspect for reusability.
The componets, if not in acceptable condition for reuse, should be reconditioned, or replaced with new or remanufactured parts.
Turbocharger (Identification)
The type (early model ... later model) turbocharger MUST be identified before any turbocharger or componets are exchanged/transferred.
Early Model Turbocharger
Example of early model design turbocharger. Reference (E) is the rear face of the flywheel housing.
Some early model engines have a turbocharger (1) that fastens to a mounting bracket (2).
The Mounting bracket is installed in the vee of the cylinder block.
Later model engines have the turbocharger installed in the vee, but it fastens directly to the cylinder block and mounting bracket (2) is not needed.
Later Model Turbocharger
Example of later model design turbocharger. Reference (E) is the rear face of the flywheel housing.
All turbocharged Remanufactured Engines will have the later model turbocharger with no mounting bracket.
When a turbocharged Remanufactured Engine is installed as a replacement for an earlier model turbocharged engine, the exhaust pipe-to-turbocharger connection must be modified for the:
- * Correct alignment and exhaust pipe size between the exhaust pipe tubing ... and
- * The lowered centerline and smaller diameter of the Remanufactured Engine turbocharger.
NOTE: Early model turbochargers require:
- * A 101.6 mm (4.00 in) nominal outside diameter exhaust pipe tubing to connect to turbocharger outlet (C).
Later model turbochargers require:
- * A 88.90 mm (3.50 in) nominal outside diameter exhaust pipe tubing to connect to turbocharger outlet (D).
Exhaust Manifold
Two different exhaust manifold groups 9N3612 or 1W1448, are used on the later model engines that have the turbocharger fastened directly to the cylinder block (does not have a mounting bracket).
The Remanufactured Engine (EXCEPT 0R3687)1 is built using ONLY the 9N3612 Exhaust Manifold Group.
1The 0R3687 is built with the 1W1448 Exhaust Manifold Group.
The 9N3612 Exhaust Manifold Group includes the necessary parts to connect the exhaust manifolds to the turbocharger:
- * 1 each 2W1929 Exhaust Manifold (L.H.)
- * 1 each 2W1930 Exhaust Manifold (R.H.) ... and
- * 2 each 1W7794 Tube Assemblies (bellows type)
- * 1 each 2W1930 Exhaust Manifold (R.H.) ... and
NOTE: In some applications, Ford C Series and International Harvester Trucks, the exhaust manifold on the Remanufactured Engine can have interference with the truck frame.
If the manifold interference occurs in these applications, it may be necessary to remove the manifold from the Remanufactured Engine and install a 1W1448 Exhaust Manifold Group:
- * 1 each 2W1931 Exhaust Manifold (L.H.)
- * 1 each 2W1932 Exhaust Manifold (R.H.)
- * 2 each 1W7793 Tube Assemblies (bellows type)
- * 1 each 2W1932 Exhaust Manifold (R.H.)
NOTE: In some applications, an economical decision should be made to either:
- * Make minor modifications to the machine frame or engine mounting rails ... or
- * Install the 1W1448 Exhaust Manifold Group.
NOTE: For identification purposes, the manifold part number is cast onto the surface of each manifold.
Sperry-New Holland Combines
For Remanufactured Engines that are to be installed in Sperry-New Holland Combines:
- * Remove the load stop pin and install a 4W9007 Torque Control Pin (spring end up).
- * Remove the torque control group and install an 8N3840 Temperature Compensator Conversion Group.
- * Remove the governor outer spring and install the correct outer spring as a replacement.
- * Remove the torque control group and install an 8N3840 Temperature Compensator Conversion Group.
