the bolt threads and seats with molybdenum
disulfide oil.

necting rod cap faces the same direction as the
“Y” mark “b” on the connecting rod.
• After installing the big end bearing, assemble
the connecting rod and connecting rod cap

Install by carrying out the following procedures in
order to assemble in the most suitable condition.
e. Tighten the connecting rod bolt while
checking that the sections shown “a” and
“b” are flush with each other by touching the

f. Loosen the connecting rod bolt, remove the
connecting rod and connecting rod cap and
install these parts to the crankshaft with the
