CLUTCH ALIGNMENT
Clutch Alignment Tool Use
Clutch alignment is controlled by the number of washers
that are placed behind the driven clutch on the
transmission input shaft. Adding washers behind the
driven clutch will move the drive belt toward the
moveable sheave of the drive clutch. Removing washers
from behind the driven clutch will move the drive belt
toward the stationary sheave of the drive clutch.
1.
Remove the seat.
2.
Remove the LH side panel and footwell to gain
access to the outer PVT cover (see Chapter 5 for
removal).
3.
Loosen the hose clamp and remove the PVT air
outlet duct hose from the outer PVT cover.
4.
Remove all outer PVT cover screws and remove the
cover.
5.
Mark the drive belt direction of rotation and remove
drive belt (see “Drive Belt Removal”).
6.
Install the Clutch Alignment Tool.
7.
Place the alignment tool in the sheaves of the driven
clutch and hold firmly as you rotate it down between
the sheaves of the drive clutch.
Clutch Alignment Tool:
PA-49011–A
8.
As you rotate the tool down between the drive clutch
sheaves, the tool should touch the clutch shaft
bearing while maintaining a clearance of roughly
.020” between the tool and stationary sheave of the
drive clutch.
9.
If the alignment tool hits the stationary sheave before
it reaches the shaft bearing, the driven clutch will
need to be spaced out to correct the alignment.
• Remove the driven clutch. Add the required
amount of alignment washers to obtain the correct
measurement with the alignment tool. You may
need to add more than one alignment washer.
Alignment Washers:
(.060”) PN: 7556120
10. If the alignment tool touches the shaft bearing but
has an excessive amount of clearance between the
tool and stationary sheave, the driven clutch will
need to be moved in to correct the alignment.
• Remove the driven clutch. Remove the required
amount of washers to obtain roughly .020”
clearance between the tool and stationary sheave.
NOTE:
The number of washers behind the
driven clutch will vary between vehicles.
It may not be possible to achieve perfect
alignment with the tool as previously
described, due to the thickness of the
alignment washers. It is better to have
clearance between the tool and stationary
sheave of the drive clutch than to have the tool
touch the stationary sheave before it touches
the shaft bearing.
11. After completing the clutch alignment procedure, the
belt should ride in the drive clutch with an
approximate .020” gap between the belt and
stationary sheave and a larger gap between the belt
and moveable sheave.
