Features and Operating Mechanisms

Crankshaft - The crankshaft is made from high
quality, aerospace grade steel.
journal surfaces are nitrided to surface harden.
There are 3 kinds of crankshafts: thin-wall, thick-
wall, and solid front mains which can be
identified by looking at the center of the front of
the crankshaft or prop oil cavity. The thin-wall
and thick-wall crankshafts are each available as
fixed-pitch or constant-speed.
models have a plug installed in front of the inner
diameter of the front main bearing cavity.
Constant speed models have a plug installed at
the rear of the front main bearing cavity.

Connecting Rods - The connecting rods are
made from aerospace grade, high quality steel.
They have replaceable bearing inserts in the
crankshaft ends and bronze bushings in the
piston ends. The bearing caps on the
crankshaft ends are retained by two bolts with
self locking nuts. Caps are tongue and groove
type for improved alignment and rigidity.
Camshaft and Valve Operating Mechanism -
The camshaft is located above and parallel to
the crankshaft. The camshaft actuates hydraulic
lifters that operate the valves through push rods
and valve rockers.
