Cylinder Liner Servicing

Servicing
At every piston inspection, check also liner running
surface and cylinder head gsket seat.
Renew heavily scored liners. Remove any
slight scores or high spots with emery cloth.
Remove any shoulder marks. The nitrided cy-
linder liners need not to be extra re-roughe-
ned.
Job:
Before cleaning the liner, cover up the crankcase
interior. Prior to piston removal, any severe top ring
TDC reversing marks must be removed, and in any
case when installing oversize rings. To avoid damage
to the liner running surface in the zone of the rever-
sing mark and below, the following procedure is
recommendable:
Place a metal plate, 1 mm smaller in diameter than
the liner, on the piston. Turn piston high enough so
that the ceconditioning work will not affect the run-
ning surface below the reversing mark. Before star-
ting the job, close clearance between piston and
liner with grease. Remove reversing mark by means
of emery cloth. When the job is finished, clean liner
thoroughly.
After cleaning the liner, gauge the wear (job
03.03.01).
Liners are to be roughened whenever pistons
are removed (job 03.06.01).
