Drive Clutch Installation - Arctic Cat Panther 1974 Manual

DRIVE CLUTCH INSTALLATION
Install Drive Clutch
Equipment Necessary: 3/4-lnch Socket, Air Impact
Tool and Torque Wrench
1. Place the drive belt on the driven pulley.
2. Move the drive clutch into position near the
crankshaft and loop drive belt onto the
clutch.
3. Secure drive clutch to crankshaft with
capscrew and lock washer, using a 3/4-inch
socket and air impact tool. Tighten the
capscrew to 75 ft. Ibs. torque, using a
3/4-inch socket and torque wrench.
4. Check alignment between drive clutch and
driven pulley (see Drive Clutch/Driven Pulley
Alignment, page V-24).
e
CAUTION
e
If service was performed on the drive clutch or
a new drive clutch is installed, alignment is to
be checked between the drive clutch and driven
pulley. When alignment is not as specified,
accelerated belt wear, poor performance and
component failure may occur.
ALIGNMENT INSTRUCTIONS
Drive Clutch/Driven Pulley Alignment
Equipment Necessary: Clutch Alignment Bar,
1/4-lnch Block
II
Note: Two items that must be checked when
aligning the drive clutch and driven pulley are
PARALLELISM and OFFSET. The first item to
check and adjust, if required, is parallelism, then
offset.

Parallelism Adjustment - Remove the brake
cable, clutch shield and drive belt (see
Remove Brake Cable, Clutch Shield and Drive
Belt, page V -26).
Install the clutch alignment bar between the
sheaves of the driven pulley, making sure that
bar is as far down between sheaves as possible.
Allow sheaves to release and hold alignment
bar in position, Fig. V -23.
Note: Alignment bar must extend beyond the
front edge of the drive clutch.
Place a 1/ 4 -inch block on the drive clutch hex
shaft and allow alignment bar to lay on the
block. All measurements must be taken with
the alignment bar laying on the block.
Measure dimension X and Y, Fig . V -23, at
front and rear edge of the drive clutch, using a
scale or calipers. Write the two dimensions on
a piece of paper for reference . Compare
dimension X and Y against Rule A and B.
Rule A - Dimension Y must be more than
dimension X.
Rule B - Dimension Y must never exceed
dimension X by more than 1/ 16-
inch (0.0625).
II
Note: Manufacturing tolerances for both di-
mensions (X and Y) are"±" 1/16-inch (0.0625).
For service recommendations, conform to Rule A
and B as stated above.
5. If dimension Y is less than dimension X,
parallelism between ~ngine mainshaft and
driven pulley shaft is not correct. If
dimension Y is more than dimension X (see
Rules A and B), the offset can be adjusted
(see Offset Adjustment, steps 6-8, page V-24l.
6. Offset Adjustment - I nstall clutch alignment
bar between the sheaves of the driven pulley,
making sure that bar is as far down between
sheaves as possible . Allow sheaves to release
and hold alignment bar in position.
