Lubrication

Front Suspension

The front suspension does not require lubrication.

Rear Suspension

Lubricate the suspension pivot shafts with POLARIS Premium All Sea-
son Grease at the intervals outlined in the Periodic Maintenance Table 
beginning on page 62 and before seasonal storage. When operating in 
heavy, wet snow conditions, lubricate every 500 miles (800 km).

Lack of lubrication will adversely affect your ride and the life of the sus-
pension. For more information about suspension lubrication and adjust-
ments, see your POLARIS dealer.

MAINTENANCE

Lubrication

Driveshaft Bearing

Inject grease into the fitting on the 
speedometer sensor housing until 
grease purges from the seal on the 
inside of the tunnel.  This should 
take approximately two pumps.  Do 
not use more than four pumps.

Throttle Cable

Lubricate the throttle cable lightly 
with grease or oil. With the engine 
off, turn the handlebars to the left 
and lubricate liberally as shown.

Choke and Choke Cable

Lubricate the choke slide and cables 
lightly with oil or grease. Before 
turning the engine off, operate the 
choke intermittently to draw mois-
ture out of the choke plunger area 
and reduce the possibility of the 
choke becoming frozen.

Chaincase Oil

Check the chaincase oil level at the 
intervals outlined in the maintenance 
charts beginning on page 62. The sight 
glass (1) is located on the lower rear of 
the chaincase. Maintain the oil level at 
or slightly below the center of the sight 
glass (2). Change the chaincase oil after 
the first 500 miles (800 km), then every 
1000 miles (1600 km) or seasonally.

POLARIS recommends the use of 
POLARIS Synthetic Chaincase Lube. 
See page 102 for the part numbers of 
POLARIS products.
