Husky 281 Oiler Issues
« on: October 18, 2014, 10:17:20 am »
I've got a Husky 281 one that I'm having trouble with the oiler.
I replaced the plastic oiler gear part# 503557501 twice because it gets striped out by the pump.
Thinking it was possibly the pump gear I also replaced that and it still striped the plastic gear.
I do have the spacer washer between the gear and seal.

I'm not sure where to go from here.

Here's what I'm working with.

Does the pump shaft spin easily by hand?

Also make sure the pump splines mesh up with the driver splines.

Both oil pumps turned freely with about the same amount of minimal resistance.
It seemed like the gear in the pump never meshed properly with the plastic worm gear.

This could very well be the problem?

I was using two brand new worm gears on two different oil pumps and got the same result.

Gear engagement will be tightest when the axis is centered on both  gears. If for some reason the mesh is way high or low the contact will be less and could wear the plastic gear quickly. Make sure somethings not causing the pressed non gear to seat or the pump housing...
