Title: Proper chain length for my saw?
Post by: logman81 on November 28, 2013, 11:02:16 AM
I recently just bought a used jonsered 630 super in really good shape. My problem is trying to figure out how many links of chain I need . It currently has a Windsor  20" bar and a seven tooth sprocket and a 72 link chain. The chain is to long even with the adjuster maxed out. I need a chain with less links but don't know how many?

I don't know your saw or bar, however, if the chain is to long to adjust it may have stretched past the adjustable length of your saw.  If that is the case removing one link will solve the problem.  God Bless, Ward and Mary.

I believe I remember reading somewhere that Windsor made some 20 in bars that needed a 70 driver chain

I probably read it on here but I have no clue what thread I suppose you could take 2 out and try it. A friend of mine had a 630 seemed to be a good old saw I think there similar to a 266 husky

Yup just took two drive links out and it fits now so 70 links, now I know what size to get for it.

If the chain had stretched a 70 may be to short, If so, a couple bucks to have someone insert one link will fix it.

No the chain was fairly new so I don't think their was much stretch.

A serious chainsaw user should own a tool to break and mend chains even if its just the granberg tool that's built on a pair of vicegrips.Many times I picked up new chains at flea markets and yard sales that just needed to be shortened, for chump change. Frank C.

I've thought about buying one and doing my own chains, but that's as far as I've got.
Our local Stihl dealer will shorten a chain for 4 bucks.
I know it's right when he's done with it.
The job probably wouldn't be quite as right if I cobbled it together! :-[

Every Windsor 20" 3/8 that I have or have seen is 70dl.  4 of mine are.  So I assume they are all 70dl.

This left me curious, as my 1975 Stihl 041 had a Windsor 20" bar on it running 3/8" Stihl chain. Thought it was the same chain as the 20" bar on my new Stihl MS361.

Replaced the bar on the 041 with a Windsor bar from Bailey's as the nose roller on the old Windsor bar (original for all those chains all those 30 years) was worn out.
Just looked at the label on the Windsor bar packaging and it has this. Indicates 72.
Am I missing something?  Wouldn't be the first time. :)

I am sure they did, as did other brands. It was more common earlier than it is by now.

......

Some times it matters which bar mount the bar is for, as well as when the bar was made.
Called bar lengths seldom are accurate.

In most cases there is a clue on the bar about the dl count it is meant for, even when the bar is quite worn.  ;)

...but then there are factors like sprocket size that may change the dl Count you actually need in a given situation..... smiley_roller
