254xp bar issues

[Acerforestry]

Ok thanks for the info. I've added a replacement oil pump / cover plate from a donor saw in decent nick, all should be functioning ok but result is the same - minimal oil from outlet point but now if saw is tipped slightly back when chain and brake cover are off, loads of oil is coming out of the handle end of the pump cover. Did wonder if the fit of the grommet that is supposed to seal off the oil reservoir was a bit loose; I assumed that when the cover was bolted on the seal was pushed slightly tighter, but if it is worn / enlarged, I guess that could cause what I'm getting, quite a lot of oil dripping out of the saw but virtually nothing on the bar

This will show you the parts - looks like you are either missing a rubber seal or it is out of place -

An old trick is also to feed the pick up pipe through an o ring, this will hold the pipe further from the crankcase and increase the joint between the pipe and the pump.

There are two types of worm wheel for driving the oil pump, one for .325 sprocket and another for 3/8. They are not interchangeable.

Ok, again will bear all this in mind - prior owner had been faffing about with the saw a lot in what was possibly a clueless manner so there is no guarantee that component parts are matching up

And cheers for the parts diagrams I hadn't got this set
