Renewing ring gear
Renew the flywheel ring gear if the gear teeth
have become so worn that the starter motor pinion
will not engage.
1.
Grind a groove as deep as possible in the ring
gear and crack it open with a chisel. Remove
the ring gear from the flywheel.
Use protective goggles due to the risk of
metal shivers.
2.
Clean the contact surfaces on the flywheel
with a wire brush.
3.
Heat the new ring gear evenly around its
circumference to 100 -150°C.
4.
Place the heated ring gear on the flywheel so
that the marking with the part number is
facing the engine when fitting the flywheel.
Make sure the ring gear is securely against
the flywheel. If necessary, knock down the
ring gear with a plastic hammer.
5.
The ring gear must not be cooled rapidly but
be left to cool in the open air.
