Removal
1. Raise the vehicle and place vertical supports underneath it. Remove the gearbox as described in chapter 7A.
2. Using a marker, mark the original relative positions of the drive disk and crankshaft, then unscrew the bolts holding these elements together. If the crankshaft rotates, wedge the toothed ring of the drive disk with a screwdriver (see illustration 11.3).
Note: If there is a ring between the bolts and the drive disc, mark which side it faces the disc, then remove it.
3. Remove the drive disc from the crankshaft.
Caution: When removing the drive disc, wear protective gloves - the edges of the ring gear teeth may be sharp.
4. Clean the flywheel, removing oil and grease from its surface. Inspect the disc surface for cracks and make sure all the teeth are present. Place the drive disc on a flat surface to assess the degree of warpage.
5. Clean and inspect the mating surfaces of the drive disc and crankshaft. If necessary, replace the rear crankshaft oil seal before installing the flywheel.
Installation
6. Place the drive disc on the crankshaft. Make sure that the marks for the relative positions of the elements applied before removal are aligned. It should be noted that some engines are equipped with a dowel pin or offset bolt hole to align the disc with the crankshaft. Before installing the bolts, coat their threads with anaerobic sealant and install the ring on the drive disc if necessary.
7. Tighten the bolts in a crisscross pattern to the specified torque. In this case, it is necessary to jam the drive disk crown by inserting a screwdriver between the teeth.
8. If the front pump O-ring/seal located in the gearbox is leaking, take this opportunity to replace it.
9. The rest of the assembly is carried out in the reverse order of removal.
