ENGINE COMPONENT AND LOCATION 85 Crankshaft W2033313 1. Alignment Tab, Block 3. Thrust Washer 2. Alignment Tab, Cap 4. Upper and Lower Bearings 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.
