Removal of the scraper ring in the
lining
If the scraper ring is so firmly seated that it
cannot be removed by hand, use the following
method:
1 Turn the crankshaft so that the piston is
moved as far down as to allow the plate
99 168 to be accommodated below the
scraper ring.
2 Fit tension lugs 98 515 on the edge of the
cylinder liner in such a way that the liner
will not be pulled out of place.
3 Position plate 99 168 on the piston crown.
4 Press a piston ring into the liner until it is
below the scraper ring.
5 Fit handle 99 168 on impact setting tool
99 074. If it proves difficult to fit the bolt in
the handle, the head of the bolt can be
ground down slightly. Take care not to
weaken the bolt if this is done.
6 Screw the bolt into the plate.
7 Pull up the plate until it abuts against the
piston ring pressed into the liner.
8 Drive out the scraper ring with the impact
setting tool.
9 Fit the scraper ring in place after the piston
has been fitted.
