Installing:
Install the piston by following the removal
procedure in the reverse order as appro-
priate.
Note:
The recess in the piston crown must be
located towards the injection pump; see
Fig. 69.
– The piston ring gaps must be offset by
120° in each case; oil the rings well in
their grooves.
For each cylinder bore a figure is stam-
ped on the crankcase and another figu-
re on the cylinder. The two figures, if ad-
ded together, represent the thickness of
the shim plates to be inserted at the ba-
se of that cylinder; see Fig. 70.
Example:
Figure on crankcase
Figure on cylinder
Shim plate thickness
needed
These shim plates compensate for cylin-
der and crankcase manufacturing toleran-
ces; in addition the gap is reduced to
within a tolerance range of 1.0 - 1.5 mm.
– Attach shim plates 70/1 to the cylinder
with a small amount of grease.
– Oil the cylinder bore well.
Note:
If spare parts are obtained, the manufac-
turer attaches the shim plates to the
crankcase or cylinder. They are not inclu-
ded in the set of gaskets.
