ENGINE COMPONENT AND LOCATION 85
Crankshaft
1. Alignment Tab, Block
2. Alignment Tab, Cap
The crankshaft is drop forged steel and induction hardened. It has seven journals
with replaceable bearings. Five oversized replacement bearing options are available
to accommodate crankshaft regrinding.
The rear main cap (No. 7) includes an attaching point for the lube pump. Thrust
washers to control axial movement straddle the central journal (cap No. 4). The
remaining caps (Nos. 1–3, 5 and 6) are numbered to facilitate correct assembly.
A Teflon® seal bearing directly on the crankshaft flange is used at the front of the
crankshaft. The front seal has an outer felt ring which serves as a dust cover. At the
rear of the crankshaft is another seal that bears directly on the machined surface of the
crankshaft gear. Additionally at the rear, there is a groove in the rear crankshaft flange
for an O-ring which forms a seal between the flange and the gear.
