What You Can Do With This Manual

This Engine Overhaul Manual walks you through diagnosing abnormal engine noise, testing for leaky valves and worn piston rings, removing and disassembling cylinders and pistons, fitting crank pin and mainshaft roller bearings, reassembling flywheels and crankcases, rebuilding the transmission and clutch, and adjusting the rear and front wheel brakes. Clearances and fits are called out throughout — for example valve stem-to-guide clearance of 0.0035 to 0.0055 inch and roller bearing clearances of 0.0006 inch — so you can rebuild to the same tolerances the factory specified rather than guessing. Chapter 15 lists the special factory tools by stock number, so you know exactly what’s needed for jobs like pulling the clutch hub or lapping crankcase main bearing races.
