SPEED SELECTOR PIVOT ADJUST-
MENT

The Speed Selector is factory set for optimal perfor-
mance at each forward and reverse speed setting.
However, if speed position 1 is too slow, the speed can
be increased by changing the pivot position one turn. Do
not turn pivot more than one turn - increasing forward
speed using this method reduces reverse speed by a like
amount, and inadequate reverse speeds will result.

Adjust as follows:

1. Loosen pivot jam nut to permit pivot adjustment

(Figure 17).

2. Pull hitch clip pin out of pivot and remove washer.

3. Looking at end of threaded Speed Selector shaft, turn

pivot one turn counter-clockwise.

4. Reassemble pivot to control arm and secure with

washer and hitch clip pin.

5. Tighten jam nut.

6. Check speed position 1 for adequate speed. If unit

still moves too slowly, return pivot to original position
and use speed position 2 as a starting speed in place

TRACTION DRIVE CLUTCH ROD
ADJUSTMENT

Initial Adjustment

The traction drive clutch rod should initially be adjusted
so that there is no slack in the rod when moved slightly
from side to side, but bellcrank arm remains in fully down
position. To adjust tension on the rod:

1. Loosen adjustment hex nuts (Figure 18).

2. Tighten top hex nut while holding rod. Tighten just

until slack in rod is removed.

3. Tighten lower hex nut securely.

Run-In Adjustment

1. After 5 hours of use, check for proper adjustment.

Readjust clutch rod if necessary by increasing ten-
sion on rod. A small amount of bellcrank arm move-
ment is permissible if unit passes operating checks
described in the Caution at left. Optimal adjustment
provides 1/32" clearance between traction drive
disc and rubber ring on friction disc when drive
lever is released 
(see Figure 14). 

CAUTION

Do not over-tighten, as this may cause traction drive
to engage without depressing the traction Drive
Control (bellcrank arm must remain in down position).

Verify that the rods are not overtightened: With Speed
Selector in position 1 and traction Drive Control fully
released, push snowthrower forward. The unit should
move forward freely. 

If unit does not move forward freely, the rod has
been over-tightened. To remedy, loosen tension on
clutch rod slightly, and recheck.
