9.Lift the drive belt over the edge of the drive pulley and engage the pulley, beveled edge in, and slide the drive belt pulley plate and drive shaft into position. Install the two hex head screws and lock washers removed earlier, and tighten securely (Figure 46).

10.Reach around to the back of the unit, and making sure the drive belt is fully engaged in all pulleys, reconnect the tension spring to the threaded stud to maintain tension on the drive belt (Figure 47).

NOTE: The beveled edge of the drive belt should be engaged against the transmission pulley and the two pivoting idler pu//eys, and the flat side of the drive be/t should be engaged against the larger, angled pu//ey with the wider groove (Figure 48).

ii.Reassemble covers to unit in reverse sequence of disassembly.

DRIVE CHAINS

General

The drive chains may be accessed by tilting the back of the unit up, and supporting it securely to prevent the unit from falling backward during service. Drive chain access is from under the unit, and extreme care must be used when checking, tightening, or replacing drive chains. Do not tip the unit for service if the fuel tank is full. Drain the fuel tank carefully, and follow all precau- tions for handling gasoline when performing this step.

Drive chain tension may be adjusted by moving adjustable sprocket mounting brackets (front chain) or the drive axle (rear chain) to achieve desired tightness. Chains will have i/8” (front) - l/4” (rear) of flex between sprockets when properly tensioned.
