TRACTION DRIVE ADJUSTMENTS
(5HP MODEL ONLY)
An adjustment to the wheel drive
bail cable may be required if loss
of traction occurs, or if the ma-
chine creeps in forward or reverse
when the WHEEL DRIVE BAIL
is not engaged. Adjusting the
wheel drive bail cable will tighten
or loosen the tension on the drive
belt that transmits power from the
engine to the transaxle (transmis-
sion).
Traction Drive Check
Perform the following test to deter-
mine if an adjustment is necessary.
1. Move the machine to a hard-
surfaced, clean, level area such as
a driveway.
2. Brace the front left wheel
against an immovable object such
as a wall or a sturdy fence post.
Make sure that the vacuum attach-
ment will not strike the wall or
fence post during the following
tests as damage to the attachment
could result. Also, make sure that
the rear wheels are on a hard, level
surface.
3. With the engine running, shift
into 3rd gear and slowly engage
the WHEEL DRIVE BAIL. One
or both of the rear wheels should
spin in place. If neither wheel
spins, the belt tension is too loose.
Adjust the wheel drive bail cable
as described on this page.
4. With the engine running, shift
into 4th gear and slowly engage
the WHEEL DRIVE BAIL. The
belt should slip on its pulleys, pre-
venting the rear wheels from turn-
ing. If the wheels turn, the belt
tension is too tight. Adjust the
wheel drive bail cable as described
next.
To Adjust the
Wheel Drive Bail Cable:
1. Shut off the engine, disconnect
the spark plug wire from the
spark plug, and make sure that all
moving parts have come to a com-
plete stop.
2. To tighten a loose drive belt,
use a 1/2" open-end wrench to
loosen the lower jam nut (A,
Figure 5-11) on the adjuster (B).
Loosen the nut 2 or 3 full turns.
3. Pull the cable up until the lower
jam nut rests against the cable
bracket (D) and then tighten the
upper jam nut (C) against the cable
bracket.
4. Tighten the lower jam nut (A)
against the cable bracket (D).
5. Using two wrenches, tighten
both jam nuts securely.
6. To loosen the tension on the
drive belt, follow the previous
steps but reverse the loosening and
tightening sequence of the upper
and lower jam nuts.
7. After making an adjustment,
perform the "Traction Drive
Check" described on this page.
Repeat Steps 2 through 6 of these
adjustment procedures until the ad-
justment is correct.
8. If further adjustments to the
cable are impossible because you
have run out of threads on the ad-
juster, a secondary set of adjust-
ments can be obtained by reposi-
tioning the wheel drive bail cable
clamp (A, Figure 5-12) to the
lower hole (B) in the handlebar, as
follows:
a.) Remove the clamp from the
upper hole in the handlebar.
b.) Fully loosen the upper jam nut
(C, Figure 5-11) and slide the
cable downward.
c.) Install the clamp in the lower
hole of the handlebar.
42
d.) Obtain a preliminary tension
adjustment on the cable by re-
ferring to Step 15 of the
"Replacing the Wheel Drive
Bail Cable" instructions on
Page 43. After obtaining a pre-
liminary setting, perform the
"Traction Drive Check" and re-
peat Steps 2 through 7 of these
adjustment procedures.
9. A new belt is required if you
run out adjustments with the cable
clamp located in the lower hole in
the handlebar.
