Piston to cylinder bore clearance - checking
Pistons and connecting rods - refit
1.
Fit oil control ring rails and expander, ensuring
ends butt and do not overlap.
2.
3.
Fit 2nd compression ring marked ’TOP’ with
marking uppermost into second groove.
Fit 1st compression ring into first groove either
way round.
1.
Starting with number 1 piston, invert piston and
with arrow on piston crown pointing towards
REAR of cylinder block, insert piston in cylinder
liner.
2.
3.
Position piston with bottom of skirt 30 mm (1.2
in) from top of cylinder block.
Using feeler gauges, measure and record
clearance between piston and left hand side of
cylinder - viewed from front of cylinder block:
Piston to bore clearance = 0.02 to 0.045 mm
(0.001
to 0.002 in)
4.
Repeat above procedures for remaining
pistons.
4.
5.
Position oil control expander ring joint and ring
rail gaps all at one side, between gudgeon pin
and away from left hand (thrust) side of piston -
viewed from front of piston. Space gaps in ring
rails approximately 25 mm (1.0 in) each side of
expander ring joint.
Position compression rings with ring gaps on
opposite sides of piston between gudgeon pin
and right hand side of piston - viewed from
front of piston.
6.
7.
Thoroughly clean cylinder bores.
Lubricate piston rings and gudgeon pin with
engine oil.
8.
Lubricate cylinder bores with engine oil.
