Do I need a new Clutch Basket?
The following outlines Clutch Basket Cushion Failure. Some Clutch
baskets will last a season, and some last only hours. If the dampeners
go unchecked clutch damage will result.
Clutch Basket Cushion
Most OEM Clutches use elastomer cushions to protect the clutch from
shock loading applied to the basket by the drive train and/or engine
during normal operating conditions. The cushions are located between
the clutch basket body and the ring gear. The cushions take up the
slack between the ring gear and clutch basket so that under normal
loading they rotate as one. Under extreme loading the cushions provide
a cushion so the ring gear and basket can float independently and keep
shock loads from being transferred to the clutch.
As the cushions wear, the system gains slack and shock
loads start getting transferred to the clutch. This creates a
hammering effect between the clutch basket and ring gear. The
hammering transfers to the clutch plates and causes the plates to
wear away at the clutch basket and center clutch hub. If the
cushions continue to go unchecked, the hammering progresses until
the clutch fails.
Checking Your Clutch
Basket for Cushion Failure
Prior to installing the z-Start Pro,
it is recommended that you check the condition of
your Clutch Basket and Center Clutch Hub. An
indication of failing clutch basket cushions is
grooving or notching of the Clutch Basket
Ears—where the tabs of the friction discs index
into the clutch basket. See image below.
