FAQ's

Q: I just purchased a set of pistons from you. What are the torque values for the cylinder and head on my snowmobile.

See Tech section for specific models. In general most snowmobiles with individual cylinder (non monblock motors) Cylinders = 22-24ft lbs and Head = 18-20 ft lbs. Monoblock motors 800xp, Mach Z 1000 and Polaris 800 IQ and Rush: Cylinders = 38 ft lbs, Head = 18-20 ft lbs.

Q: I need to order a new track for my sled. How do I know if I need a fully clipped track, a clipped every third track, or a closed every third window track?

The OEM’s have varied over the years in the types of tracks they put on the sleds relative to clip variation and window variation. Fully clipped tracks are only required on sleds that use extrovert drivers, meaning the drive sprockets on the drive shaft need to protrude through the window openings. Very few original sleds have these style drivers. These drivers are needed in high horsepower applications where the introvert style drivers tend to ratchet under hard acceleration. It’s okay to use a fully clipped track on any sled, but you are adding weight that is not necessary.

Q: Do I need any special tools to install my new clutch kit?

MCB recommends that you at minimum purchase a primary clutch puller to install a performance clutch kit.

Q: Will my new clutch kit give me more top end speed?

Typically no, but in some specific cases on certain models it will. The typical gain you will see when purchasing a new clutch kit is the snowmobile will accelerate faster, and it will backshift / downshift faster providing better performance in cornering ability and keeping the motor at the proper load so that it does not bog coming out of the corner.

It will not do any good to install a performance clutch kit in a worn out clutch.

Q: How do I know if my clutches are worn out?

See technical section and video of a worn out clutch and what to inspect.

Q: I just had my shocks rebuilt and when the snowmobile is sitting on the ground two to three inches of my suspension is being used just to hold the snowmobile up, why?

Because a snowmobiles suspension is coupled and is a two pivot style system it is very important that you inspect your snowmobiles suspension on a perfectly flat floor with no dollies under the track or ski’s. Any used snowmobile even with fresh shocks with have what we call “sag, or ride in”. Two to three inches is normal, remember you don’t hit bumps, you are driving over holes. The suspension needs to fall in the hole and fill the hole. If you’re suspension was fully taught when this happened you would be sent over the handlebars. Do yourself a favor and watch a Baja truck suspension in action. Ninty percent of the absorbtion is done in the suspension falling out and filling the hole!
