A dump valve in the clutch gear housing provides oil pressure relief when the clutch is engaged.

DESCRIPTION OF INPUT GROUP

The input group transfers power from the engine flywheel to the marine gear. The marine gear may employ two
different input groups; torsional coupling or rubber block system. The rubber block system consists of the driving
ring, drive spider and rubber blocks. The type of input group used is determined through a series of tests conducted
by the manufacturer. The input gear shaft-transfers rotational power from the engine to the input gear which transfers
rotational power to the forward or reverse clutch.
