2100 CD bar tightener bolt

[haywire woodlot]

Hi, all! Do any of you saw experts out there know if the bar tightner bolt on a husky 2100 is interchangable with any of the later saws?  Ie 288, 395xp. It's getting DanGed hard to find original parts for these old dino-saws.

Something should fit . If nothing else just a metric bolt of the same size .

I have no idea of what size it is .Mine works fine so I never fooled with it .

[haywire woodlot]

A metric bolt just rattles it's way out, I believe the original bolt has a keeper of some sort on the end to keep it from coming out. All of my parts saws are already missing this part so it must be common for it to fail. It's also difficult to find a metric bolt with full threads and a slot head.

Can you use a locknut for a keeper? Or drill the end and unsert a cotter pin or something?
Most of the newer ones have a square plastic piece that fits tight over the end of the adjuster screw and slides into a slot in the case.

There's no keeper on it. Just use a bolt and burr the thread after it goes thru the adjuster that should do it. I've replaced them on other saws with a bolt, just cut a cross in the head with a hacksaw.

I brought the IPL of that thing up on Partstree .com and all it said was M5 x 40 .

T :)hanks for the info guys, I'll go down to duncan industrial on monday and see if they've got the apropriate metric bolt, ones I bought in the past have'nt  had enoungh threads for this purpose. It' ll be cheaper than getting the orignal part from a saw shop anyways.

[Al_Smith]

Most likely where you will be screwed up is the length of threads as you say . I suppose you could chase the threads with a metric tap but not too many including myself has such an item .

I really have no idea but the possibley exists that a bolt from a 3120 or some other modern Husky saw would fit .It doesn't appear from the IPL to be anything special than just a bolt with longer threads .

I phoned up to nieser's in lake cowichan, and he figured might have a match. So i drove up there and we found that the bar tensioner bolt from a 298xp is a close enough fit to work. However the 298 is a discontinued saw too! so those parts will be hard to get in future as well. I catch myself saying this a lot, But If a guy had some money...

A bolt from a 480 might work, if you have an old saw lying around. The 2100 is rather closely related to the 480 series, so it might work.

[sablatnic]

Been looking it up.  Same part number for Hu480 and Hu2100. #501 54 86-01, but donīt know if it's still sold.
Maybe you can use the bolt for the Hu281. I remember it as being quite long. It is #501 81 57-01.

Btw. It is M8 with a rectangular head, and I remember it as having a larger diameter than 8mm at the head. Don't know anything about the length, and don't have a saw I can measure.

[Al_Smith]

 A bar tightening bolt won't be an 8 MM . That is about  3/8 of an inch or the size of the bar stud  in a lot of cases  anrd it would be large saw to even use that size .

[sablatnic]

Sorry. Got it mixed up. What you call bar tightening bolt we call the chain tightener over here.
It should be M5, that is correct. Sorry for the confusion. But 40mm seem too short it is only about 1-5/8". My guess would be more like 2 or 2-1/2". Could be wrong again.
I should be part # 5017927-01, and it is not the same as on the Hu480. Just checked.

[Al_Smith]

 It just boils down to the fact that if you fiddle with old stuff you have to learn to be resourcefull . As far as little incidentals such as a bolt ,I've made them but not everyone can do this .

Here's an idea .Just take the old bolt and nut to a friendly saw shop if you can find one and see what they can some up with . Nobody ever said for example that you can't put a modified Stihl part on a Husqvarna or vica versa .

I would think on Vancouver Island you could find thousands of 2100 Huskies as they were quite popular in their day .Even yet today they hold their own as a racer but parts are  getting scarce .

[haywire woodlot]

Thanks for all the input guys. I guess should have made it more clear in my last post that the tensioner bolt from the 298 did fit and I bought the last two he had there. The guy at the saw shop said that when he reordered, they would probably be discontinued.
Al, as far as fiddling with old stuff, I bet only 50% of the bolts in that old saw are the original size, I've drilled and tapped most of them to accept larger bolts as strip out from rattling around! Luckily those old saws have heavy castings with lots of meat!
This time of year you see lots of old 2100's driving around sticking out of loads of last minute firewood, kind of like a firewooder's flag! When ever I see one in our local buy, sell  and trade rag, I try to snap it up, but they go pretty quick.

 My 2100 came from some island in Washington state after sitting for years in a barn because of a bad coil . I like you have retaped a lot of holes in that arm breaking rascal . It pulled over so hard I hard to put a D-handle on it . Powerfull old duffer ,I'll give it that for sure . The danged thing should have  had a decomp but I suppose maybe people were a tad tougher in the 80's .

However on that subject I have gained info from a well known eastern coast racer that the 2100 thin single ring models are easy to roll over .Of course mine is the double thick ring model as luck would have it .
