An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools to perform these functions properly. Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons. Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. Therefore, the warnings in this publication and the warnings that are on the product are not all inclusive. If a tool, a procedure, a work method, or operating technique that is not recommended by Caterpillar is used, ensure that it is safe for you and for other people to use. Ensure that the product will not be damaged or the product will not be made unsafe by the operation, lubrication, maintenance, or the repair procedures that are used.

The hazards are identified by the “Safety Alert Symbol” which is followed by a “Signal Word” such as “DANGER”, “WARNING” or “CAUTION”. The “WARNING” Safety Alert Symbol is shown in Illustration 2.

Summary

The slot for pin (3) in the face of the clutch plates wear during normal operation. This will cause unnecessary circumferential movement that could interfere with the housing and can result in incorrect shifting, breakage, or overheating conditions.

Note: The slots for the pin were previously known as “tang slots”.

The part may be reused if the part has all of the criteria that are listed.

If there is no radius or chamfer at the location for a radius and 45 degree chamfer (13), do not reuse the part.

Identification of Worn Transmission Clutch Plates

When a part number for the clutch plate is not visible, or worn plates from several transmissions have been mixed, use the following procedure to identify the part number of the clutch plate:

Measure the outside diameter of clutch plate (6).
With the known outside diameter, use Table 3 and Table 4 to check the features of the part. Compare the information in the table to the clutch plate to determine the part number.
To identify the worn material of the clutch plate, lightly tap the clutch plate with a steel ball peen hammer. A steel clutch plate will make a ringing sound. A dull sound is made when cast iron, ductile iron, or plates that are made of powdered metal are struck.

Refer to Table 3 for specifications for your clutch plate.

NOTICE

The wrong surface finish and grinding pattern on clutch plates, pistons, or other reaction faces can cause rapid wear of the disc assemblies. Refer to the column, "Surface Finish" for the correct finish. Refer to Table 3. A simple surface finish test for minimum roughness and grinding pattern for 0.63 µm (25 µinch) to 1.4 µm (55 µ inch) surfaces is performed by rubbing the edge of a copper coin around the circumference of the reaction face. The surface has the correct pattern and minimum roughness if some of the copper is transferred to the face.

Perform the following steps to find all of the information for your clutch plate:

Look in the column for outside diameter (6) in Table 3 to find the part number.
Find the part number for the clutch plate in Table 4 in the column for the part number.

Salvage Procedures

Salvage of a Clutch Plate and Piston with Worn Reaction Pin Slots

Show/hide table




Illustration 5	g01330317
Normal wear of the clutch plate due to movement around the circumference of the pins, clutch plate, and housing.

The wear limits for the width of the slot for the pin should not be exceeded. If the maximum width for the slot is exceeded, the parent metal could fatigue. This could result in failure of the clutch plate.

Inspect the clutch plate for warping and cracking after determining that the clutch plate meets the minimum specifications for wear. Refer to Reuse And Salvage Guideline, SEBF8013, "Transmission Clutch Plates and Disc Assemblies with Sintered Bronze Friction Material" and Reuse And Salvage Guideline, SEBF8031, "Transmission Clutch Plates and Disc Assemblies with F37 and F37X Friction Material".
Put the plates in a vise with 4C-3750 Jaw Caps and weld the tangs, which will leave the unworn portion of tang (2) as a witness mark. This will allow the tooling for cutting the new slot to be placed as close as possible to the original slot. Do not weld the slot higher than the area that is not worn. This operation can be performed more precisely by cutting the welding rod in half.
Grind the excess weld off the sides of the slot for pin (3). Use a 222-3074 Wheel Grinder Gp. Use a carbide bit for deburring with a 6.0 mm (0.24 inch) shank for this operation. Polish the marks from grinding for appearance and the proper surface finish.
Clamp the clutch plate on a horizontal mill and machine the width of the slot for pin (3) to the specified dimension. Refer to Table 3 for the correct specifications.
Deburr the clutch plate and finish grind the surface on a surface grinder. Refer to Table 3 and Table 4 for the correct specifications.

Machine the top of the clutch plate even with the housing or the clutch plate.

Thoroughly clean the side of housing that faces the clutch. Deburr the side of housing that faces the clutch. Remove all nicks or raised surfaces.
Inspect the sides of the housing. Inspect the housing for the side that has the greatest wear. Clamp the housing onto a mill so that the worn side is up.
Bore a hole into the housing to accept a sleeve.
1. Use a 17.46 mm (0.687 inch) spiral boring tool or a straight boring tool with a 12.7 mm (0.50 inch) tool guide.
2. Line up the tool with the unworn portion of the hole.
3. Bore the hole only in the worn area. The depth of the counterbore should allow the sleeve to remain even with the top of the housing surface.
Fabricate the sleeve from SAE 1020 steel with a 0.05 mm (0.002 inch) press fit. Drill the sleeves to 12.29 mm (0.484 inch). Ream the sleeve to the correct size after installation.
Coat the sleeve with Loctite 242.
Press the sleeve into the housing. Machine the excess stock from the assembly. The surface of the sleeve should be even with the surface of the housing.
Turn over the housing. Ream the sleeve to the correct size. Use the unworn portion of the hole as a guide.

Repair of Thick Separation Plate

Make a fixture for repairing dowel holes from a worn plate.
1. Find an old plate in good condition. Also obtain a new plate as a guide.
2. Align the old plates and the new plates together and dowel the plates after the plates are precisely aligned.
3. Bore the old holes in the plate in order to accept 12.7 mm (0.50 inch) drill guides with this inside diameter. The drill guides will ensure correct alignment.
Bore a hole into the housing in order to accept a sleeve.
1. Use a 17.46 mm (0.687 inch) boring tool with a spiral or a straight contour and a 12.7 mm (0.50 inch) tool guide.
2. Line up the tool with the unworn portion of the hole.
3. Be sure that you only bore the deformed portion of the hole. The depth of the counterbore should allow the sleeve to remain even with the top of the housing surface.
Fabricate a sleeve for repair from SAE 1020 steel with a 0.05 mm (0.002 inch) press fit. Drill the sleeve to 12.29 mm (0.484 inch). Ream the sleeve to the correct size after installation.
Coat the sleeve with Loctite 242.
Press the sleeve into the housing and remove the excess stock. The surface of the sleeve should be even with the surface of the housing. Invert the housing. Ream the sleeve to the correct size. Use the unworn portion of the hole as a guide.
Clamp the plate onto a mill table. Line up the machine on the center of the hole. Ream the sleeve to the correct size.

Note: An adjustable reamer that has an outside diameter or 12.7 mm (0.50 inch) can be used in order to size the hole correctly if the adjustment screw is backed out slightly. This will provide full extension. Make a test cut on a piece of scrap with a 12.29 mm (0.484 inch) hole in order to size the reamer.

Repair of Housing with Blind Reaction Pin Holes

Housings with blind holes for the reaction pins have holes that are not drilled completely through the housing. These housings can be repaired by lining up the pin hole with the guide in the counterboring tool.

Bore a hole into the housing in order to accept a sleeve.
1. Use a 17.46 mm (0.687 inch)boring tool with a spiral or a straight contour and a 12.7 mm (0.50 inch) tool guide.
2. Line up the tool with the unworn portion of the hole.
3. Bore the hole only in the worn area. The depth of the counterbore should allow the sleeve to remain even with the top of the housing surface.
Fabricate a sleeve for repair from SAE 1020 steel with a 0.05 mm (0.002 inch) press fit. Drill the sleeves to a diameter of 12.29 mm (0.484 inch). Ream the sleeve to the correct size after installation.
Coat the sleeve with Loctite 242.
Press the sleeve into the housing and remove the excess stock. The surface of the sleeve should be even with the surface of the housing. Invert the housing. Ream the sleeve to the correct size. Use the unworn portion of the hole as a guide.
Clamp the housing to a mill table. Align the drilled hole and ream the sleeve to the correct size.
