NOTICE
To avoid scratching the crankshaft and to
ease the installation procedure, lubricate the
oil seal lips with lithium-soap-based grease
and each bearing with engine oil.
TIP
Hold the connecting rod at top dead center
(TDC) with one hand while turning the nut of the
crankshaft installer bolt with the other. Turn the
crankshaft installer bolt until the crankshaft as-
sembly bottoms against the bearing.
