Pump Belt Tensioning Assembly

The belt is automatically tensioned by a spring (37). To cancel the force of the spring when removing or ﬁtting the belt, use a 1/2" ratchet wrench in the square hole in the idler arm (45).

Check that there is no abnormal noise indicating that the idler pulley is loose on its shaft. If it is loose, tighten the bolt (42) and the set screws (41), or change the bushing (44).

Check that the idler arm is not loose on its bearing. If it is, tighten the bolt (49) or change the bushing (47).

3.Remove the cotter pin (30).

4.Remove the castle nut (27) and, pulling downwards, remove the front fork.

5.Remove the upper bearing (28).

6.Taking great care not to damage the seal (31), use a hammer and a suitable rod (or similar) to knock the lower bearing out in a downwards direction.

Assembling

The assembly procedure is the reverse of the dismantling procedure.
