Crankshaft and main bearing
The crank pin and crank journal have been
induction hardened for superior durability, and the
crankshaft is provided with for balance weights for
optional balance. The crankshaft main veering is of
the hanger type. The upper metal (cylinder block
side) is provided with an oil groove. There is no oil
groove on the lower metal (bearing cap side). The
veering cap (location cap) of the flywheel side has
a thrust metal which supports the thrust load.
5.5.1 Crankshaft
(1) Color check after cleaning the crankshaft,
and replace the crank shaft if there is any
cracking or considerable damage.
(2) Bending of the crankshaft
Support the crankshaft with V-blocks at both
ends of the journals. Measure the deflection of
the center journal with a dial gauge while
rotating the crankshaft to check the extent of
crankshaft bending.
