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 service center/department.

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 construc- tion and should be replaced by original equipment manu- facturer (OEM) belts available from your nearest service center/department. 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.

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, flat washer securing pulley to engine crankshaft. Remove outside (auger) pulley only from crankshaft.

5.SEPARATE SNOW THROWER - With your assistant standing in the operating position holding the handles, remove the two (2) bolts holding the auger housing and frame together.

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

6.REMOVE HAIRPIN FROM CLUTCH ROD and re- move clutch rod from swing plate. Tip swing plate forward.

7.REMOVE AUGER BELT from around pulley.

8.RELIEVE TENSION ON TRACTION DRIVE BELT IDLER and remove traction drive belt from around pulleys.

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.

9.With tension relieved on idler, install new traction drive belt around pulleys and inside belt keepers.

10.Install clutch rod in swing plate; secure with hairpin.

11.Place auger belt around and inside the groove of auger pulley only.

12.While your assistant slowly raises handles to rejoin the auger housing and frame assembly, pull up on the auger belt and squeeze sides together above pulley so belt is fully seated in groove of pulley.

13.Move idler arm so it does not hit impeller pulley as you 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 repeat step 12. Belt must be fully seated in pulley groove when bringing the snow thrower together.

14.Install the two (2) hex bolts and tighten securely.
