This listing is for One Syringe of 50G Kluber Isoflex Topas NB 52 Special Rolling Bearing Grease. This is the special grease used by ski doo to lubricate the mag + pto outboard bearings. Once this grease dissipates off the bearings - it is just a matter of time for failure. It is my understanding it should be done every 2000 miles. Syringe has just over 50 grams. Syringe makes application, and removal of grease easier than out of the tube. Product on hand ready to ship. Shipping is Usps First Class - $2.50 - USA. Questions welcomed - thanks for looking - Alex.
