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