I. DESCRIPTION
The air cooled, four cylinder, overhead valve engine is
of the horizontally opposed type· and is basically the same
in all models.
The crankcase is two piece and die-cast in light alloy.
As the two crankcase halves are machined to mate together,
replacement can only be made in pairs.
The cylinders attached to the crankcase are of special
cast iron, incorporating fins on the outside surfaces for
cooling purposes. As the cylinders are separate, each can be
replaced or interchanged provided the matching piston is
fitted to the appropriate cylinder.
A single removable cylinder head is fitted to each pair
of cylinders, the head is also cast in light alloy
incorporating fins for cooling purposes. Valve seat inserts
and valve guides are shrunk into the head.
The crankshaft is mounted in the crankcase and
supported by four main bearings. In earlier models three of
Engine Assembly.

the bearings are of split steel backed lead-bronze type, the
fourth bearing is aluminium alloy of the bush type;
crankshaft end thrust is taken by number two main bearing.
Later models have four light alloy lead coated bearings one
of which is the split type; crankshaft end thrust is taken by
number one main bearing. At the. clutch end of the
crankshaft an oil seal is fitted, with an oil thrower and oil
return thread incorporated on the pulley end of the shaft.
The flywheel complete with starter ring gear is secured to
the crankshaft by a gland nut and located in position by
four dowel pins. Woodruff keys are used to secure the
timing gear and distributor drive gear to the crankshaft.
The four connecting rods are fitted with detachable
lead-bronze shells in the big end bearing end of the rod,
with the fully floating gudgeon pin supported in a bronze
bush at the small end of the
rod.
The pistons are fitted with two compression rings and
