Belts, Controls and Linkages

7.The belt guide must be checked and adjusted. With the engine off, engage both the auger and traction controls. Adjust the belt guide so that there is approximately 1/8 inch (.3 cm) clearance between the belt guide and the belt.

Check auger belt adjustment. See “CONTROL AND LINKAGE ADJUSTMENT” on page 2 - 7 for the linkage adjustment procedures.

REPLACING THE TRACTION BELT

The models covered in this manual use three different methods of tensioning the traction belt. As the tensioning method affects the belt replacement process, they are separated by model number.

1.Pull high tension wire off spark plug and make sure it does not contact the plug accidentally.

2.Remove two thread forming screws holding belt cover in place, and set belt guard aside.

3.Move auger drive control to DISENGAGE and wheel drive control to N, neutral. Next, remove auger drive belt from engine pulley and large auger/impeller pulley.

4.Loosen two capscrews (securing traction idler arm to front of engine. Next, remove traction drive belt from engine pulley and large traction pulley.

5.Install new belt around large traction pulley. Next, loop belt over engine pulley, making sure that belt is on inside of traction idler pulley and wire belt guide.

6.Reinstall auger belt around large auger/impeller pulley. Next, loop belt over engine pulley, making sure that belt is on inside of auger/impeller, idler pulley and wire belt retainer. Slide idler arm and pulley assembly against belt to remove belt slack and tighten capscrews.

Note: Tension belt only enough to remove slack. Do not over-tension.

7.With the engine off, engage the auger lever. Adjust the belt guide so it is within 1/8 inch (.3 cm) of the belt.

8.Install belt cover with two thread forming screws.

9.Install high tension lead and test operate unit to check traction. If little or no traction is evident, proceed to step 10. If traction operation is satisfactory, proceed to operate machine.

10.Remove high tension lead from spark plug and remove belt guard. Loosen two capscrews securing traction idler arm and slide idler arm and pulley assembly further against belt. Move assembly a minimal amount to assure belt is not over tensioned.
