REPAIR INSTRUCTIONS INSTALLATION Refer to Figure 187.
1. Position the wear ring in the spring clips of the wear ring installer J 38880 with the arrow pointing away from the installer tool. Refer to Figure 188. 188
On some wear rings it may be difficult to determine the direction of the arrow on the inside diameter. In this case, ensure proper installation by installing the wear ring with the chamfer on the inside diameter toward the engine. The chamfer on the outside diameter of the wear ring must face away from the engine.
The crankshaft wear ring is a shrink fit on the crankshaft flange. Use wear ring installer J 38880 and universal driver handle J 8092 to install the ring to the proper depth. 187

2. Heat the wear ring and wear ring installer together in a temperature-controlled oven or on a hotplate, with the wear ring on the bottom and installed in the spring clips of the installer. Work as close as possible to the engine to avoid heat loss after heating the ring. Heat to 400°F (205°C). Do not install the driver handle at this time. This allows the wear ring to maintain sufficient heat until it is fully installed on the flange.
Do not heat the wear ring with a torch. This type of heat source will not heat the ring evenly. Figure 187 — Proper Crankshaft Wear Ring Installation
3. Thoroughly clean and dry the crankshaft oil seal mounting flange. 4. After the wear ring is sufficiently heated, use heat-resistant gloves to install the universal driver handle J 8092 into the threaded hole in the center of the installation tool. 5. Remove the wear ring and installation tool from the oven or hot plate and immediately place in position on the crankshaft flange. Push the wear ring onto the flange until the installation tool is fully seated against the end of the flange. As the wear ring cools, it will shrink-fit onto the crankshaft flange. 6. Allow the wear ring to cool completely. Then remove the installation tool.
