MAINTENANCE PROCEDURES
Pulley Guard Removal
•
WARNING: Engine should be running only when
pulley guard is secured in place.
Drive Belt Removal
•
WARNING: Never start or run engine without
drive belt installed. Running an unloaded engine
is dagerous.
1. Remove hood and pulley guard.
2. Open the driven pulley by twisting and pushing the
sliding half. Hold in fully open position.
3. Slip slackened belt over the top edge of the sliding
half.
Drive Belt Condition
Inspect belt for cracks, fraying or abnormal wear (un-
even wear, wear on one side, etc.). If abnormal wear is
noted, probable cause is pulley misalignment. Check
drive belt width. The drive belt width should not be less
than 33.3 mm (1
5/16")
wide. A too narrow belt will
result in a loss of performance.
O
NOTE: When installing a new drive belt, a break-in
period of 4 or 5 laps at no more than half throttle is
strongly recommended.
Pulleys Alignment and Drive Belt Tension
y
A free floating 0.5 mm (,020")
Distance
between
pulleys
Dimension Y and X (offset); 34.1 mm (1
11/32"}.
. . . CAUTION: Dimension
"X"
must never exceed
di-
, . mension
"Y".
Dimension
"Y"
can exceed dimen-
sion
"X"
by 1.6 mm
(1/16").
The distance between pulleys should be 27 mm (10
9/16")
c.c. however, maximum vehicle performance is
obtained when the drive belt deflects by 32 mm (1
1/4")
when a pressure of 6.8 kg (15Ibs) is applied on the drive
belt.
4. Slip the belt out from the drive pulley and remove
completely from vehicle. To install drive belt, reverse
procedure.
