Known Issues
|
|
Clutch Wear:
|
As with many snowmobiles of this era, clutch wear, specifically on the primary drive clutch buttons and secondary roller bearings, can be a common maintenance item. The manual provides detailed inspection and replacement procedures.
|
|
Carburetor Icing:
|
Carburetor icing can occur in very cold, humid conditions. Proper jetting and potential use of additives are sometimes discussed, though more as an operational factor than a mechanical fault.
|
|
Suspension Bushings:
|
Wear on suspension bushings and ball joints can lead to steering looseness and irregular tire wear. The manual outlines inspection and replacement protocols.
