3. Removal of piston
Remark: Loosen and remove all screws for the screwing piston rod gland / cylin-
der block (see 2303−1).
Remove the antipolishing ring from the collar of the cylinder liner (see 2124−2).
Fit locking devices GF 94343 in order to prevent the cylinder liner from being lifted
when the piston is pulled out (for the relevant details see also Fig. ’G’).
⇒ Screw fasten both distance holders 94345 to the piston rod foot (3).
⇒ Turn crank to T.D.C. whereby piston rod gland 8 is pushed out of its seating in
the cylinder block by distance holders 94345.
⇒ Use tap 94348 to clean threaded holes of combustion residue in the piston
crown 1.
⇒ Mount suspension device 94341 to piston crown.
D Before pulling the piston out, the crosshead pin and the top end bearing must
be protected, so that entry of dirt into the top end bearing is absolutely pre-
vented.
