When installing new needle bearing, insert nee-
dles with thrust washers. Instead of expansion
sleeve, needles are held in place by 2 inner plastic
cage halves.
Use piston pin puller (P / N 529 0210 00) to insert
piston pin. Plastic halves should come off piston.
If not, pull them using a long nose pliers.

6 o’clock as illustrated. Use piston circlip installer
(P / N 529 0169 00).

the cylinder with new injection oil or equivalent.
Position cylinder head on cylinder with fins in line
with crankshaft center line. Cross torque retaining
nuts to 26 N•m (19 lbf•ft) for 277 engine type.
