Ring gear

Renewal

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.

!

WARNING!

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.

The ring gear must be turned so that the bevel 
on the teeth is facing outwards, towards the 
starter motor.

4

Lay the heated ring gear on the flywheel so 
that the bevelled side is facing the starter 
motor. 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.
