The first tank of fuel is considered the break-in period for the engine of your Polaris snowmobile. Careful treatment of a new engine will result in more efficient performance and longer life for the engine.
Excessive heat buildup during the first 3 hours of operation will damage close-fitted engine parts. Do not operate at full throttle or at high speeds for extended periods during the first 3 hours of use. Vary the throttle openings and vehicle speeds to reduce friction on all close-fitting machined parts, allowing them to break in slowly without damage.
On fuel-injected models, the engine management system utilizes both a fuel injector break-in period and oil pump enrichment program. The durations of these break-in programs are independent of each other and are timed out based on engine run time. Regardless of these automatic engine break-in and enrichment features, engine break-in procedures must be performed when the engine is new or overhauled. Be sure to consult your Owner’s Manual to find the instructions for your particular vehicle.
Oil and fuel recommendations during the break-in period vary depending on the specific model of your Polaris snowmobile. Some models require premix of the first tank of fuel. Oil added to the fuel and oil injection systems will provide necessary break-in lubrication. Engines equipped with an electronic oil pump do not require an initial fuel premix. Be sure to consult your Owner’s Manual to find the instructions for your particular vehicle.
Never mix brands of oil. Serious chemical reactions can cause injection system blockage, resulting in serious engine damage. Oils also may be incompatible, and the result could be sludge formation, filter blockage and reduced cold weather flow rates. All Polaris oils are compatible with each other.
Drive with extra caution during the break-in period. Perform regular checks on fluid levels, lines and all other important areas of the snowmobile.
Always check and fill the oil bottle when refueling. Serious damage can occur without the proper lubrication.
Drive Belt Break-In
The break-in period for a new drive belt is 30 miles (48 km). During this time, vary the throttle position under 50 percent and limit full throttle use.
Always take time to warm up the belt and driveline prior to operating the snowmobile. Free the track and skis from the ground before engaging throttle.
Washing a new drive belt before installation is not necessary. If you choose to wash your belt, use warm, soapy water and air dry the belt prior to use.
A new track will stretch during its break-in period. A typical track will be properly broken in between 250 and 500 miles (400-800 km). Track break-in time is dependent on track type, riding style, and whether your snowmobile is equipped with studs.
During the track break-in period, Polaris recommends checking track tension after every completed riding day when the track is new. See the Maintenance section of your Owner's Manual for more information.
QuickDrive Belt Break-In
The break-in period for a QuickDrive belt is 100 miles (160 km). During the 100 miles of belt break-in, the rider will hear a sound made by the drive system. After the break-in period, the sound will become similar to that of a traditional chaincase.
Improper track tension can result in track ratcheting, which will affect QuickDrive belt durability. Always maintain proper track tension.
During the break-in period, this belt sheds a fiber-type material in and around the drive system. Use a dry shop towel to clean the residue.
Stop occasionally and allow the snowmobile to cool after high throttle or high track load events. This will help the QuickDrive belt achieve maximum performance. It also will break in the engine, drive belt and sprockets properly.
On-trail break-in should be performed at speeds of no more than 50 mph (80 km/h).
Always be cautious when jumping and landing a snowmobile. Avoid “power-on” landings. Damage caused to any component by improper use or abuse is not covered by warranty.
