(3) Precautions on replacement of crank pin
metal
1) Wash the crank pin metal.
2) Wash the large end cap, mount the crank pin
metal and make sure that it fits tightly on the
large end cap.
3) When assembling the connecting rod, match
up the large end and large end cap alignment
marks. Coat the bolts with engine oil and
gradually tighten them alternately to the
specified torque.
If a torque wrench is not available, make
match marks on the bolt heads and large end
cap before disassembling (to indicate the
proper torque position) and retighten the
bolts to those positions.
4) Make sure there is no sand, metal cuttings or
other foreign matter in the lube oil, and that
the crankshaft is not scratched. Take special
care in cleaning the oil holes.
