My HD 6401/7900 conversion doesn't oil worth a crap. When I got it it oiled everything but the bar due to leaking oil lines. I replaced the lines which solved the leaking issue but very little oil is getting to the bar. The limiter screw looked OK http://www.arboristsite.com/chainsaw/168711.htm but I modified it anyway http://www.arboristsite.com/chainsaw/156738.htm with no change in oiling It is using some oil but I can't detect any on the drivers when I pull the chain out of the bar groove. The chain is getting hot and I am detecting wear to the chain/bar after a few tanks as well as some bluing of the bar. I can also see very little "sling off" from the tip of the bar. Yes, the chain is sharp. There is very little difference between my new-ish Carlton bar and the bar that came with the saw so I don't believe it has to do with the bar. If I run the saw with no bar I do get oil at the bar mount but it is kind of hard to judge volume that way.
My thought process is leading me to believe that being run with the leaking oil lines by the POs caused wear in the oil pump leading to sub-par oil delivery. Before I spring for a new oil pump I just thought I'd check with some other 6400 owners. Is this stingy oiling common to these saws or do I have an oil pump problem? Thanks in advance.
