SERVICE AND ADJUSTMENTS

TO REPLACE BELTS (See Fig. 23)

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 qualified 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 construction and should be replaced by original equipment manufacturer (OEM) belts available 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 position and hold the snow thrower handles. Serious personal injury and/or damage to the unit could occur if the snow thrower should fall during the belt changing process.

HANDLES

1.REMOVE GASOLINE FROM FUEL TANK - Drain gasoline from fuel tank into a suitable container, out- doors, away from fire or flame. Wipe up any spilled gasoline.

2.REMOVE DISCHARGE CHUTE - Loosen locknut securing chute rotator head to mounting bracket only enough to allow chute rotator head to be raised and discharge chute to be removed from snow thrower.

3.REMOVE BELT COVER - See “TO REMOVE BELT COVER” in this section of this manual.

4.REMOVE ENGINE PULLEY - Remove bolt, lockwasher and flat washer securing pulley to engine crankshaft. Remove outside (auger) pulley only from crankshaft.

WARNING: As the last bolt is removed, have your assistant carefully lower the handles down to the ground.

6.REMOVE AUGER BELT from around pulley.

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 repeat step 12. Belt must be fully seated in pulley groove when bringing the snow thrower together.
