Introduction
The timing gears are located inside a case at the
flywheel end of the engine.
The engine must be timed so that the camshaft
operates the valves at the correct times relative to
the crankshaft position.
Valve timing is achieved by ensuring that the
camshaft drive gear is meshed to the crankshaft gear
at their correct angular positions, refer to Engine-
General, Operation, The Four Stroke Cycle (PIL
15-00) for more information about valve timing.
