DESCRIPTION AND OPERATION The aluminium alloy, tin coated pistons have two
compression and an oil control ring and are secured
to the connecting rods by semi-floating gudgeon pins
which are an interference fit in the small-end bush.
Gudgeon pins are offset towards the thrust side of the
pistons to reduce frictional drag.
Plain, big-end bearing shells are fitted to each
connecting rod.The internally toothed timing belt is driven from a gear
which is keyed to the crankshaft, belt tension being
controlled by a semi-automatic tensioner.
The trochoidal type oil pump is mounted on the front
of the engine and carries the crankshaft front oil seal.
Drive to the pump is via a Woodruff key inserted in the
crankshaft.
