3.13) Cylinder and piston - removal
See Figs. 72-84 and 72-85.
â—† NOTE: Prior to removal, mark cylinders and pistons in pairs to ensure
correct coordination on re-assembly. The cylinders are all
identical in design. The piston pin center is offset from piston
center.
Move the piston to T.D.C.position and mark with an arrow pointing towards the
gearbox. When the piston is cleaned, the arrow (1) becomes visible. This arrow
faces towards the gearbox on all 4 cylinders and serves to ensure correct
assembly of the pistons with offset centers.
Carefully pull off the cylinder. Support the piston by hand to avoid damaging
piston and piston rings. Lift out the piston pin circlip (2) with a mono hook circlip
puller (3), part no. 976380, see 00-00-00 sec. 10.6.
