Husqvarna ZTH5223 Manuel D’Utilisation

English-

41

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).

Lubricate the bearings with ball bearing 
grease.

Taking great care not to damage it, tap the

Adjust the castle nut (27) until there is zero 
play in the bearings. Loosen the castle nut to 
the nearest hole and fit the cotter pin.
