Ski-Doo Belt-Life Updates for REV Gen4 MY2019 Sleds and Older Models | Mountain Sledder
BRP has officially announced some updates which will appear on MY2019 Summit and Freeride sleds. Also, a Warranty Bulletin 2018-10 has been issued to help customers with REV Gen4 snowmobiles that experienced premature belt failure with assistance in resolving any issues.
Ski-Doo Belt-Life Updates for REV Gen4 Sleds
An investigation of 2018 sleds that experienced premature failures identified the issue was localized in very specific conditions (altitude, snow conditions and riding styles) and related to engine movement plus clutch clamping force; new mounts along with an updated CVT calibration will resolve this.
The most easily noticed change will be an air intake vent on the left side panel for all Summit, Freeride, MXZ, Backcountry and most Renegade E-TEC powered models (Renegade Enduro will not have this).
This is a product improvement in 2019 for additional CVT system cooling and the only outward visual cue customers will see as they visit dealer showrooms. Behind the side panel there is additional ducting and a new belt guard that directs air for cooling from the intake vent to the secondary pulley. This is an intake-cooling vent, not an exhaust vent.
There are more specific improvements that have been made to each model based on their expected use, which include combinations of new engine mounts (specific designs for mountain or trail use), a finned secondary pulley, new pulley calibrations and the additional intake ducting mentioned above.
For customers with REV Gen4 snowmobiles that experienced premature belt failure, BRP invites them to visit their dealership. Warranty Bulletin 2018-10 has been issued to provide them assistance in resolving any issues.
