7.Work the belt out from between the pulley and the frame, around the transmis- sion cover spring, then up and out of the machine.

Installing Forward Clutch Belt

1.Stop engine, allow it to cool and dis- connect spark plug wire before working near belts. Also remove ignition key on electric start models.

2.Remove the old forward clutch belt as described in Removing Forward Clutch Belt.

3.From the front of tiller, insert the forward clutch belt in between the bottom of the engine drive pulley (I) and the top of transmission pulley (K, Figure 5-20).

4.Insert the bottom half of belt into the smaller, rear-most groove of the transmis- sion pulley (F, Figure 5-19). Now slip the top half of belt under the belt guide (D, Figure 5-18) and onto the large groove of engine drive pulley (L, Figure 5-19).

5.Reconnect the forward clutch cable to the correct hole in the idler arm bracket, as shown in Figure 5-17.

NOTE: Be sure to run the reverse clutch cable on the pulley side of the cover support brackets (G, Figure 5-21).

IMPORTANT: Belt must be installed on the inside of the belt guide (H, Figure 5-21).

6.Reinstall the reverse clutch belt. Insert the bottom of the belt into the frame, then pull down on the belt and roll it onto the large, forward-most groove of the trans- mission pulley (P, Figure 5-20).

7.Reinstall the belt cover.

8.Test for correct tension on the forward clutch belt (see Checking Forward Belt Tension).

REVERSE CLUTCH BELT REMOVAL AND INSTALLATION

The reverse clutch belt (J, Figure 5-22) is driven by the engine drive pulley (I, Figure 5-20). When the Reverse Clutch Control knob is pulled out, it pulls the reverse idler arm and pulley (N) which tightens the belt against the engine drive pulley. This drives the transmission drive pulley (L), resulting in reverse motion.

Removing Reverse Clutch Belt

1.Stop engine, allow it to cool and dis- connect spark plug wire before working near belts. Also remove ignition key on electric start models.

2.Remove belt cover (Figure 5-13) by removing two flange locknuts.
