REPAIRS
Hydraulic Pump Belt
Check the belt every 75 to 100 hours of operation. Inspect carefully for large cracks and significant damage. The small cracks that arise from normal use do not make it necessary to change the belt.
Changing Pump and Deck Belts
1.Drop the deck to its lowest position.
2.Remove the operator’s foot plate.
3.Remove the outer deck belt guards.
4.Using a 9/16" socket on the bolt of the idler pulley, loosen the deck belt. Roll the belt off the deck pulleys.
5.Roll the belt off the clutch pulley on the crankshaft.
6.Loosen the bolt (2) and twist the clutch tie down (10) aside (see the “Engine mounts” diagram).
7.Using a square, 1/2" ratchet wrench, slacken the pump belt and roll it off the pulley for one of the hydraulic pumps.
8.Remove the old belt.
9.Fit the new belt on the crankshaft pulley.
10.Swing the idler pulley towards the engine and fit the belt.
11.Fit the belt around the pulley on the right (looking upwards from below the mower).
12.Attach the spring and use a square, 1/2" ratchet wrench to cancel the force exerted by the belt tensioner.
13.Fit the belt around the left pulley (looking upwards from below the mower).
14.Check that the belt is not twisted and that it runs correctly around all the pulleys.
15.Check that there is perceptible play between the clutch and the clutch tie down (10) when the clutch flange is turned by hand (see the “Engine mounts” diagram). Adjust/twist the tie down and, using the nut (1), tighten the bolt (2).
16.Fit the deck belt. Check that the belt is not twisted and that it runs correctly around all the pulleys.
17.Fit the operator’s foot plate.
18.Fit the outer deck belt guards.
