Rework Procedure
Group 1
1. Remove the transmission from the vehicle.2. Replace the 1T1795 Cover on the front of the converter with a new 1T2018 Cover, 1S3311 Snap Ring and 2M2561 O-Ring. The O-ring goes under the cover to make sure the cover does not rotate. If the 1T1795 Cover is cracked, check the engine crankshaft endplay to determine if engine damage has occurred.
3. Drill out the two 5 mm diameter holes in the rotating housing to 12.5 mm as shown in Illustration 1. Because the 1T1866 Rotating Housing is balanced, it is important that the two holes are the same size and 5.0 mm holes are used as a pilot for the 12.5 mm drill.4. Disassemble the transmission following the instructions in the Service Manual. Replace all the sleeve bearings in the clutch hubs after polishing the sleeve bearing journals on the clutch shafts to a surface finish similar to that of a crankshaft bearing journal or a wrist pin. Polish both journals on all three clutch shafts using the following procedures:A. Disassemble each clutch group to the basic shaft assembly.B. Put a center in the chuck journal of a lathe and a live center in the tailstock.C. Mount the shaft between the centers of the lathe. Do not chuck on the shaft or use a drive dog as it may damage the surface.
D. Start the polishing operation using 1U8282 Emery Paper and several drops of oil. Run the lathe at approximately 500 RPM. To improve the polishing efficiency, oscillate the emery paper across the journal while the shaft is turning. Continue the process for a minimum of five minutes. The shaft size will not be changed, and you cannot over-polish the journals. Use Caterpillar emery paper as other emery paper may not produce the same results.
E. Stop the lathe and wipe the journals off with a clean towel. Repeat Step D using 1U8283 Emery Paper for a minimum of 5 minutes.F. Repeat Step E using 4C8510 Crocus Cloth for a minimum of 5 minutes.G. After polishing, be sure to wash the shafts and flush the lube holes.5. Replace all hub sleeve bearings.6. If PS8113, Service Letter dated April 3, 1994, has not been performed or if the existing clutch pistons are of the design that has a 6Y8263 Seal Assembly bonded to them, replace each of them with the new loose-lip design 1141071 Piston, 9W9399 I.D.
