The tra n smission assemb ly transmits power from the en-
gine t::> the track which propels the Yehicle .
The "Primary Sheave Assemb l y" atreches directly to the

The "~concary Sheave Assemb:y·• has i ts own mounting
base and is larger in diameter than the Prinary Assembly.

PROCEDURE FOR
INSTALLING THE
TRANSMISSION BELT:
1. Loop one end of the replo.cement belt around the prima.ry
sheaves (Fig. 18).
2. Rotate secondary sheaves until one of the flat surfaces
on End Cap is adjacent to engine. This will JJermiL belL
to pass bet\veen end cap and engine (Fig. 19).
3. M ov e belt between end cap and engine.
4. notate large shea-ves until the above mentioned flat spot
is a.dja.ecnt to t he flat surface on the steering column
(Fig. 19).
5, Move belt between end cap and steering column.
6. Work bottom of belt under and around the two large
sheaves as much as possible.
7. Spread secondary sheaves with :tands (Figu1·e 19).
CAUTION: Do not forc i bly pry sheaves apart with tools.
6. The secoudar ·.v sheaves can be spread by holding the
fixed or stationary half next to the mounting pedestal,
an<.l L 'oL a lin g the movable half toward the rear of the
vehicle. Thi::; will allow pulley to move up the 1·amps in
the enc c ap .
9. Continue lo work bell the remalndel' of the way around
sheave.
10. Replace transmission guard.
11. ReplGt.t:e shroud.

DRIVE BELT
Correct sta.L·te.r motor drive IJ~H tension is extremely
imp01·t:mt, o. loose belt will cause s lipp age and a tight belt
will cause a ratcheting effect of the drive pulley.
PL·oueuure fur Gt.u jus l ing bell tension:
1. RP.movP. ont.e't' belt guard .
2. Ad.1ust belt tension so that drive belt is pulled
down in pulley as shown ln Figur·e 20. Be

SKI ALIGNMENT
Ski alignmAnt is necessu·y when the skis are not parallel
with each other aml lh~:: vt:hlcle body when the har.dle bar is
in the normal stroight - driving position.
To align skis, proceed as follows:
1. "Place handle bar in the no ::- -
mal :;traight-driving pos : tion .
2. Remove shroud.
3. RemovP. nut and washer from
steering arm , Figure 21, Ref. 1.
