  • Upper Gear Set

    My SEI-116 was leaking at the seal carrier assembly(SEI#97-102-02K) on my upper unit. As I was disassembling the drive, the locknut(SEI# 98-102-07) was not very tight.

    Is there a reason that this nut was so loose?. What is the torque spec? The unit is about 8 years old with maybe 100-150 hours on it, and this is the first issue I've had with it. I'm replacing the washer and nut, in addition to the seal carrier assy.

    The nut is used to pull the bearing together to preload them. It does not have a torque spec. When removing it you need to start over with the preload. remove and install the bearings and use the nut to pull them together until you get 3-5 inch lbs of rolling torque. Use loctite on the nut.
