RING GEARThe steel ring gear (1) and flywheel (2) is a two-piece assembly. Prior to assembly, the ring gear isheated to expand its diameter. It is then installed onto the flywheelandallowedtocool.Astheringgearcools, it contracts onto the flywheel, and locks in place.INSPECTION OF RING GEARIf inspection of the flywheel indicates that ring gear replacement is necessary, follow the belowprocedure.REMOVAL OF RING GEARRemove the ring gear as follows:1. Shut off the engine, apply the parking brake, chock the wheels, and perform any otherapplicable safety steps.2. Remove the transmission.3. Remove the flywheel. Refer to Section “Removal and Cleaning of Flywheel.”BURNSTo avoid injury from burning, use lifting tools andheat-resistant gloves when handling heated components.4. Using an acetylene torch, cut the ring gear 1/2 to 3/4 of the way through, without allowing theflame to touch the flywheel.5. The uncut portion will now yield. Tap the ring gear to remove it from the flywheel.

INSTALLATION OF RING GEARInstall the ring gear as follows:1. Support the flywheel, ring gear side up, on a solid flat surface.BURNSTo avoid injury from burning, use lifting tools andheat-resistant gloves when handling heated components.NOTICE:Do not, under any circumstances, heat the gear over 204°C(399°F). Excessive heat may destroy the original heat treatment.Heat treating “crayons” which are placed on the ring gear and meltat a predetermined temperature, may be obtained from most toolvendors. Use of these “crayons” will ensure against overheatingthe gear.2. Rest the ring gear on a FLAT METAL SURFACE, and heat the gear uniformly with anacetylene torch, keeping the torch moving around the gear to avoid hot spots.3. Use a pair of tongs to place the ring gear on the flywheel with the chamfer, if any, facing thesame direction as on the gear just removed.4. Tap the ring gear in place against the shoulder of the flywheel. If the ring gear cannot be tappedinto place readily so that it is seated all the way around, remove it, and apply additional heat.5. Install the flywheel. Refer to Section “Installation of Flywheel.”6. Install the transmission.
