Use the following procedure to recondition the flywheel. Clean the flywheel with a non-caustic solvent and dry with compressed air.
To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 40 psi (276 kPa) air pressure.
Flywheels used with manual transmissions may be resurfaced to correct minor wear and scoring.
When resurfacing the flywheel, refer to dimension "A", to determine if the flywheel was previously refaced or it if has adequate stock for refacing. See Figure 31927 .
Note: Flywheels used with automatic transmissions cannot be resurfaced. If damaged, replace flywheel.
Note: Flywheel resurfacing information is provided for guidance only. Detroit Diesel Corporation assumes no responsibility either for the results of any work performed in accordance with this information or for the ability of service personnel to detect heat cracks.
Note: Any crack or heat check in the flywheel could cause it to separate. After resurfacing, carefully examine the flywhee, for any cracks or heat checks. If there is any question, do not use the flywheel.
Follow these steps to replace ring gear:
Note: Do not heat the ring gear to a temperature higher than 278C (500F). Heating beyond this temperature will adversely affect ring gear hardness.
