4-5-6 CLUTCH DAMPENER:
The 4-5-6 clutch dampener (476) is located inside
the 4-5-6 clutch (w/output carrier shaft) hub
assembly (475). The dampener apply plate (477)
and the dampener retaining ring (478) are also
housed in the hub assembly (475).

The 4-5-6 clutch dampener is designed to dissipate
or minimize unwanted clutch vibration as well as
to eliminate or reduce the noise that may be
associated with it. A paper friction material is
bonded to both sides of the dampener, and contacts
the 4-5-6 clutch hub (475) and the dampener apply
plate (477).

When the 4-5-6 clutch is applied or released, the
possible vibration and noise related to these actions
are transferred to the dampener through the bonded
4-5-6
friction material. The vibration and noise is then CLUTCH
absorbed or dissipated by the dampener. The DAMPENER
dampener is in contact with lubrication fluid, but APPLY
does not require any apply fluid force. RING

Wear of the dampener friction material may result
in a vibration noise during a 4-5-6 clutch apply or
release.
