550xpg

[matt99]

I can't seem to keep the chain properly tensioned every time I go to fuel up I have to adjust the chain tension then its really slack when I have to fuel up done a couple hours cutting from new its on a Oregon chain can't see its the chain stretching that much. It doesn't seem to be oiling that well can't see oil coming off the bar I've got the oiler turned up to max. What am I doing wrong?

Oregon chain stretches a LOT.

 

I use 21 bpx and even at the end of the chain it still stretches. That's on a 550xpg with 13" bar.

I use Oregon 21 bpx on 15" with 550xpg, does stretch but don't hav to tension every fill up, usually goes tighter (initially) if oiler not working them very slack, is your filing up to scratch or cutting rough dry wood?

On reflection think one of my colleagues had similar problem and thread on the tensioner stud was stripped or hole cracked

All chain will "stretch" when getting hot, and brand has nothing to do with that stretch, as it is a natural and temporary result of the chain getting hot. It may help to turn the oiling up, and not over tightening the chain in the first place may also help.

Remember to remove any added tightening before setting the saw aside so it cools down. Worst case, failing to do so may result in a bent crankshaft.

 

The permanent stretch is a totally different matter, as it really is wear on rivets and in rivet holes.
