4-8. Difference Between Piston Actuated

and Mechanical Fan Drive Clutch

The basic difference between the piston

actuated and mechanical fan drive clutch is the

redesign of the late clutch to eliminate the

hydraulic disengagement

feature.

The

mechanical design provides complete in-

terchangeability between piston actuated and

mechanical housing

and

cover

assemblies.

However, individual parts contained within the

assemblies are not interchangeable.
