Removal, inspection and installation of the flywheel / faceplate

Withdrawal

1. Remove the transmission (chapter 7A or 7B). It makes sense to also check the cuffs and replace them if necessary.

2. On models with non-automatic transmission, remove the clutch (chapter 6). It makes sense to check or replace clutch components

3. Mark the flywheel/faceplate and crankshaft with a center punch or blot of paint to align them when installing.

4. Block the flywheel/faceplate from turning by locking the flywheel teeth or by securing the faceplate/flywheel to the cylinder block/crankcase with steel strip and bolts. Loosen the bolts one by one (see fig. 19.4).



5. Remove flywheel/faceplate. Don't drop this knot, it's very heavy (see fig. 19.5).



6. If necessary, remove the adapter plate from the cylinder block pins (see fig.19.6).

Inspection

7. Clean flywheel/faceplate to remove grease and oil. Inspect the surface for cracks, nicks, burn marks, and other imperfections. Small scratches can be removed with sandpaper. Check for cracks or broken teeth on the ring gear. Lay the handwheel/faceplate flat and check for warping with the end of a ruler.

8. Clean and inspect mating surfaces of flywheel/faceplate and crankshaft. If the left crankshaft seal is leaking, (paragraph 20) before installing the flywheel/faceplate, replace it.

9. Thoroughly clean the inside of the flywheel/faceplate assembly. Clean the threaded holes for the bolts in the crankshaft, as well as the threads of the bolts from the old sealant.

Installation

10. Install the adapter plate on the cylinder block pins.

11. Then install the flywheel / faceplate on the crankshaft so that all the bolt holes are aligned (it can be done in the only way). Make sure that the marks made before removal are aligned. Block the flywheel/facebutton in the same way as when removing. Apply sealant to the bolts and insert them. Tighten the new bolts evenly in a criss-cross sequence (in two or three stages see Specifications).

12. On models with non-automatic transmission, install the clutch (chapter 6).

13. Install the transmission (chapter 7A or 7B).
