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.
