1 - 7C0790 Cylinder As.1 - 8N9384 GasketAction Required
Parts Stock
Inspect all 8N9678 and 8N2507 Servo Piston Assemblies, and all 7C0790 and 7C0791 Cylinder Assemblies in parts stock. Remove all servo piston assemblies and cylinder assemblies assembled with a flat faced pin. Illustration 2 in the attached procedure shows pins having a smooth spherical radius and a flat face on the ends.
Affected Product
See the attached procedure.
Service Claim Allowances
This is a 2.5-hour job.
Parts Disposition
Any parts removed (with the exception of cores used for Caterpillar Remanufactured parts) can be rendered useless and scrapped immediately upon completion of the repair.
Attach. (1-Rework Procedure)Rework Procedure
Check the upper rear corner, right hand side of the engine cylinder block for the code "D5". If the code is present, the engine has already been reworked. If the code is not present, rework as follows:
Disconnect throttle linkage. Remove fuel shut-off solenoid, air fuel ratio control, the rear governor housing and gasket, and rack servo piston assembly. See Illustration 1.
Remove the rack cylinder assembly from the servo piston assembly and replace.
Use the recommended rack cylinder assembly only (See Illustration 3). Also, do not attempt to restake pin to salvage the cylinder assembly.
Assemble and seal the governor housing. Stamp "D5" on the upper rear corner, right hand side of the engine cylinder block.
If the engine has operated significantly above high idle at any time, refer to the November 2, 1987, October 17, 1988, and March 27, 1989 Service Magazine Articles for the recommended diagnostic procedures.
