DIscs

Clutch discs start new at .104" thick. These should be replaced when the total pack wears .030". This means the individual disc thickness should not be less
than: Single disc = .074"

Two disc = .089"

Triple disc = .094"

Four disc = .097"

Note:

The friction material used on these discs is wear resistant. It will typically wear quickly for the first .002" of disc thickness, and

then wear much slower after that.

Pressure Plate anD Floaters

Check the plates periodically for warping. This warping is caused by heat put into the clutch from slipping. Check warping with a straightedge and feeler
gauges. Maximum allowable warping is .008" in any plate. Pressure plates can be resurfaced to a minimum thickness of .525" (after surfacing). Floater plates
should never be resurfaced. Be sure to align the balance marks when reinstalling the plates.

CAUTION:

Never put new discs into a clutch that has a warped pressure plate or floater plates. There will not be full contact across

the face of the discs and they will wear out quickly. On the same note, discs that were used in a clutch with a warped pressure plate or
floater plates should never be used in a new clutch assembly.

• Hubs make full spline contact with

input shaft

• There is clearance between hubs

(and rivets)

• There is clearance between the

bottom disc and flywheel bolts

Note:

Friction pads should be stacked over each other as shown in Diagram A and not staggered.
