Transmission Belt Tensioner
The transmission pulleys are driven by a multi−ribbed
belt that is tensioned with a spring loaded idler assem-
bly. If the transmission belt tension needs to be engaged
or disengaged, follow the following procedure:
1. Park machine on a level surface. Make sure engine
is OFF. Remove spark plug wire from the engine spark
plug.
2. Locate the transmission engage/disengage shaft
next to the engine (Fig. 2).
CAUTION
Be careful when rotating the transmission en-
gage/disengage lever. The lever is spring loaded
and may cause personal injury.
3. To disengage the spring loaded idler from the trans-
mission drive belt, use a 3/8” wrench to rotate the en-
gage/disengage shaft 1/4 turn clockwise.
4. To engage the idler into the transmission drive belt,
use a 3/8” wrench to rotate the engage/disengage shaft
1/4 turn counter−clockwise. The transmission belt is
properly tensioned when the alignment marks on the en-
gage/disengage shaft and the transmission cover are
aligned (Fig. 3).
5. Connect spark plug wire to spark plug.
