OIL PAN The oil pan includes an oil level/temperature sensor with connector. The filler tube and dipstick mounting ports are also components of the oil pan. The oil pan is plastic or steel with a threaded plug for draining. The plastic pan has a groove in the mounting flange which accepts a molded elastomer gasket for a seal. The steel pan is sealed with a gasket on the oil pan flange. Twenty-two spring-loaded screws clamp the pan to the block. 12 Oil pans with the sump at the front or at the rear are available to accommodate axle forward or axle back chassis. CRANKSHAFT 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.
