Snowmobile Break-In
Engine Break-In
The first tank of fuel is considered the break-in period for the engine of your snowmobile. Careful treatment of a new engine will result in more efficient performance and longer life for the engine.
Excessive heat buildup during the initial hours of operation will damage close-fitted engine parts. Do not operate at full throttle or at high speeds for extended periods during the break-in period. 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. To guarantee proper break-in of your snowmobile, consult your vehicle’s Owner’s Manual.
Oil and fuel recommendations during the break-in period vary depending on the make and model of your 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 have different break-in procedures and may 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.
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 varies by belt type. During the defined break-in time, vary the throttle position under 50 percent and limit full-throttle use.
New drive belts should be washed with warm, soapy water and allowed to air dry prior to 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.
Track Break-In
A new track will stretch during its break-in period. A typical track will generally be properly broken in between 250 and 500 miles (400-800 km), though exact miles vary by brand. 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, check track tension after every completed riding day when the track is new. See your Owner's Manual for more information.
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.
