SERVICE AND ADJUSTMENTS
TO REPLACE BELTS (See Fig. 20)
The auger and traction drive belts are not adjustable. If the 
belts are damaged or begin to slip from wear, they should 
be replaced. It is recommended that the belt(s) be replaced 
by a qualifi ed service center.
NOTE: It is recommended that both the auger and traction 
drive belt be replaced at the same time.
The V-belts on your snow thrower are of special con struc tion 
and should be replaced by original equipment man u fac tur er 
(OEM) belts avail able from your nearest dealer. Using other 
than OEM belts can cause personal injury or damage to 
the snow thrower.
WARNING: Belt replacement requires 
separation of the snow thrower. While 
separating the auger housing from the 
frame assembly, it is important that an 
assistant stand in the operating po si tion 
and hold the snow thrower han dles. Se-
rious personal injury and/or damage to 
the unit could occur if the snow thrower 
should fall during the belt chang 
ing 
process.
HINT: Insert a 3/8" drive ratchet (in the “ON” position) into 
the square hole in idler arm and rotate ratchet clockwise 
to relieve tension.
8.    With tension relieved on idler, install new traction drive 
belt around pulleys and inside belt keepers.
9.      Place auger belt around and inside the groove of auger 
pulley only.
10. While your assistant slowly raises handles to rejoin 
the auger hous ing and frame assembly, pull up on the 
auger belt and squeeze sides together above pulley 
so belt is fully seated in groove of pulley.
11. Bring snow thrower completely together and check 
carefully for proper routing of belts.  If auger belt has 
become dislodged from the pulley (by catching the idler 
arm bracket while bringing snow thrower together), 
separate the snow thrower and re peat step 10.  Belt 
must be fully seated in pulley groove when bring ing 
the snow thrower together.
12. Install the two (2) hex bolts and lock washers and 
tighten securely.
13.  INSTALL ENGINE PULLEY - Place belt in pulley groove 
and slide pulley on crankshaft.  Install fl at washer, lock-
washer and bolt and tighten securely (30-35 ft. lbs. 
torque).  Make sure belt is inside belt keeper.
14. INSTALL BELT COVER and two (2) screws. Tighten 
securely.
15.  INSTALL DISCHARGE CHUTE – See “INSTALL DIS-
 CHARGE CHUTE / CHUTE ROTATER HEAD” in the
