 Piston ring end gap:
To measure the end gap, insert the piston ring
into the cylinder bore, locating it at the lowest
part of the bore and holding it true and square;
then use a thickness gauge to measure the gap.
If the gap measured exceeds the limit replace
the ring.

Connecting Rods
 Big–end thrust clearance:
Check the big end of each connecting rod for
thrust clearance, with the rod fitted and con-
nected to its crank pin in the normal manner. If
the clearance measured is found to exceed the
limit, the connecting rod or the crankshaft,
whichever is responsible for the excessive clear-
ance, must be replaced.

 Connecting rod alignment:
Mount connecting rod on aligner to check it for
bow or twist. If either limit is exceeded, replace
it.

 Inspect small end of each connecting rod for
wear and evidence of cracks or any other dam-
age, paying particular attention to the condition
of its bush. Check piston pin clearance in small
end. Replace connecting rod if its small end is
badly worn or damaged or if the clearance check
exceeds the limit.
