Removal of loose ring in cylinder
liner
If the loose ring is so firmly in place that it cannot
be removed by hand, proceed as follows:
1. Remove cylinder head and oil sump.
2. Rotate the crankshaft until the piston is at
BDC.
3. Fit tension lugs 98 515 to the edge of the cyl-
inder liner so that the liner cannot be pulled
out of position.
4. Place plate 99 168 on the piston crown.
5. Press a piston ring into the liner until it is
below the loose ring.
6. Fit handle 99 168 on impact drift 99 074. If it
proves difficult to fit the bolt in the handle,
the bolt head can be ground down slightly but
without weakening the bolt.
7. Screw the bolt into the plate.
8. Pull up the plate so that it abuts against the
pressed-in piston ring.
9. Drive out the loose ring using the impact
drift.
Removing and dismantling piston
and connecting rod
1. Remove the piston cooling nozzles in the cyl-
inder block.
Note The piston cooling nozzle must not
be damaged.
If the jet of oil does not strike the
piston in the right place, there could
be a danger of engine breakdown.
Damaged nozzles must be changed.
