Arctic Cat has alerted their dealer network regarding all 2005 M-series sleds. It has been determined that there are two conditions that need to be addressed on the 2005 M-Series snowmobiles. As you may already know, there is a possibility of moisture having entered the gear case. If this condition exists and the service work is not performed, damage to the gear case components may occur. Second, the current drive shaft cap screw might break due to excessive vibration if the snowmobile is operated in hard-packed snow conditions.
Arctic Cat dealers have been instructed to contact all owners of record to remedy these situations. The Diamond Drive gearbox will be removed, drained and flushed, a new seal installed and new lube added. Also, a new driveshaft cap screw will be installed.
