Stihl MS180C oiler problem

[chopper47]

I have a 180C that quit oiling properly, i.e. the flow drastically reduced. I have torn it down to the point where I can get to the oil pump but am wondering how to proceed from here. It looks like the pump is pressed into place. How do I remove it? Is it a shadetree mechanic operation or must I, gulp, ask Stihl to replace the pump in the case? Thanks for the help.

My memory is a bit rusty, but I think you screw in a long m6 bolt through the plastic case into the pump body and pull it out ! (somebody correct me if I am wrong!) Regards Toby.

I think it's an m5, but it does pull right out. I bet it's not the pump though. I would guess that you need to replace the hose. They get where they don't seal against the pump, and suck air.

Hey, thanks guys for the info. I'll check out that hose.
