BELT REPLACEMENT (CONT.)

b. Remove the belt from the engine pulley. Slip the belt from under the brake pad.

c.Remove six capscrews from bottom cover to snowthrower frame. Loosen nuts (A, Figure 23) on each side to release auger pulley belt stops (B, Figure 22). Move belt stops and remove belt from pulley (C, Figure 23).

d.Belt can be removed from top or bottom. For more clearance to remove the belt, engage the traction drive lever.

5.Remove the traction drive belt as follows:

a.Pull the idler pulley (I, Figure 22) away from the belt and slip the belt from the pulley.

b.Slip the belt off the traction pulley and then the engine pulley. The arm for the front idler pulley (G, Figure 22) may have to be pivoted to provide clear- ance for removing the belt from the traction pulley.

c.Pull the belt out between the auger pulley (F, Figure 22) and traction pulley.

6.Reverse the procedure to install the belts. Be sure there are no twists and the belts are properly seated in the grooves. Adjust the belt stops so there is 1/8” (3mm) clearance between belt and stop. The pattern for both belts is shown in Figure 24.

7.Check the traction drive tension and auger drive ten- sion. Follow the procedures under AUGER/TRAC- TION DRIVE TENSION below.

8.Make sure the auger stops when the auger drive lever is released. Make sure traction drive stops when the traction drive lever is released. If not, check the drive tension. If a problem exists, see your dealer.
