Oil - Front Diff, Rear gear case - ** Service Caution! **

by Dav Ash, 2006-04-14


It is particularly important that wet brake compatible oil be used in the rear gear case of the LTA700, 450,and 750. Use of an oil in this case that is not made for this application will result in the deterioration of the rear brake parts and eventual reduction and loss of rear brakes, along with resulting in an expensive repair.
Not all dealership mechanics are necessarily up to speed on the need for this different rear gear case oil and there have been cases where shop service employees have replaced the wet brake oil with common gear oil. It pays for the King Quad owner to be diligent and be sure that the shop is aware of the proper oil to use. Some reports of dealers installing the incorrect oil has been reported.

Double check any fluid that you are interested in. Make sure it is WET BRAKE compatible.
