chain swapping

[Khornet]

If I buy a 20" bar (.050) for my Poulan 306a, will I be able to use my Stihl and Husky 20" .050 /72dl chains on either saw? I see on the Oregon and Windsor sites that the Poulan uses a 70dl chain. Is there a significant difference? Please explain if you would be so kind. I understand pitch and guage and the number of drive links in the circumference of the chain. Is the sprocket different?

Thanks

You will need to make your chains 2 links shorter to use them.

Sounds like the Stihl/Husky chains will be 2 drive links too long. That is close to 3/4 inch at the bar studs and your Poulan chain adjustment may or may not extend far enough to tighten the chain.

I think the difference in length is the shape of the tail of the bar and the distance between studs.

Windsor 20TMX50STA uses 72 drivers and it should fit the Poulan, unless my chart is wrong. It is listed for 10-10 Macs, but the mount is the same.

I have always run a 16" on the Poulan, but I guess I'll get a 20" bar and if the chains don't fit, I'll buy a couple that will. I was just hoping to minimize cost and duplication. Thanks for all the advice and I really enjoy reading the posts.
