IMPORTANT:Replacing internal seals or disassembly of the gearbox will void warranty.

Gearbox oil should be changed after the rst 50 hours and then every 1000 hours or once a year thereafter with a SAE 90EP equivalent gear lube (1.06 quarts/1 liter). There is a drain plug on the bottom of the gearbox to assist in draining the oil and a breather plug on the top for lling the gearbox. Besides the plugs there are two seals that can be replaced without voiding the gearbox warranty. Input shaft seal #5MP114374 and output shaft seal #5MP114375. Contact factory for any other repairs to the gearbox. : 51,1*
