Engine Description - Crankshaft and Connecting Rods

Fig. 7

Here we see the crankshaft and connecting rods.
The four connecting rods ride on the plain-bearing crankshaft in lead-bronze bearing inserts. All connecting rods have bronze piston pin bushings. All crankshaft journals are soft nitrided. Bearings 2 and 3 (seen from the clutch-end) are split-sleeve inserts. Bearing 4 may be replaced without disassembling the crankcase by removing the timing gear cover.

Bearing 1 also takes up the crankshaft thrust. The flywheel, which also carries the starter gear teeth, is attached to the crankshaft by means of a gland nut and fixed in position by 8 aligning dowel pins. The camshaft gear and the distributor drive gear are locked to the crankshaft through Woodruff keys. The crankshaft pulley is attached to the crankshaft through a hex bolt and locked with a Woodruff key. The crankshaft is sealed in the crankcase through oil seals located at the flywheel and crankshaft pulley ends.
