Poulan Pro 42cc 18" chainsaw blade keeps coming off!

Using standard Poulan brand bar chain oil.

Can not keep chain from coming off. Chain slips off sprocket when under load. Have the screw attachment on the bar opened to max to keep chain tight, have also tried with small amount of slack, but all to no avail. Chain continues to slip off sprocket and slides off bar when using.

Help!!

Time for a new bar and chain would be my guess. Even a loose chain will usually stay on the bar, so something else is probably bad, like a bent link in the chain and or a worn grove in the bar.

Good luck

Thanks, Bud. I figured as much. The sprocket is worn, pretty bad, has some serious grooving going on and I notice the washer that backs up to the sprocket is beginning to wear down, as well. Don't know if I will spend the money to fix this brand.....it's pretty useless. Will probably go get a Stihl and really tick off my wife. Thanks for the input.

if the sprocket is that worn, yep time for new sprocket, bar and chain, make sure and get a matched bar and chain if they are not matched you will have the same problem even with new.

if we're not supposed to eat animals why are they made out of meat?

Poulan Chainsaw Blade Comes Off

I had this problem with an 18 inch Poulan.
Turned out that the bolts holding the engine to the saw case had vibrated out of the bottom of the case and engine.
Thus the engine was moving slightly and throwing the chain.
Ordered new bolts from Poulan. Problem solved.
Hope this helps. YMMV.
