Removal and installation of the flywheel / faceplate

Withdrawal

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

2. Remove the clutch (depending on version) see chapter 8. It makes sense to check or replace the clutch components and pilot bearing (centering the clutch on the crankshaft shank).

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.

5. Alternately turn out bolts of fastening of a flywheel. They should always be replaced after being turned out, regardless of condition, as they work under complex load patterns.

6. Given the position of the amplifier plate (only automatic transmissions), remove the flywheel/faceplate. Do not drop this knot, it is very heavy.

Inspection

7. Clean the flywheel/faceplate of 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 (right) side of the flywheel/faceplate, especially the recesses used as base elements for the crankshaft position/speed sensor. Clean the probe tip and check 8 that the probe is secure. Also clean the threaded holes in the end of the flywheel and the threads of the bolts - this is important, since the remnants of the old seal will loosen the connection after a while and it will no longer transmit engine torque properly.

Installation

10. When installing, make sure that the power block adapter plate (if available) installed in its place. Then install the flywheel/faceplate on the crankshaft so that all the bolt holes line up (it can be done in the only way). Make sure that the marks made before removal are aligned. Don't forget the stiffener (if available).

11. Block the flywheel/face plate in the same way as when removing. Tighten the new bolts evenly in a criss-cross sequence (in two or three stages see technical data) (see fig. 22.11).



12. Perform other installation operations in the reverse order of removal.
