help identify chains

[Toyboy]

I've picked up a Husky 51 in really nice condition. My problem is it came with 2 extra 18" chains, but I've been unable to find out anything about them other then .325 .50. They are both Oregon and the only identifying # on them is on the drive link. One has 34 and the other chain is 21
What have I got here?
Thanks

You can check out oregons website for the codes. I don't remember them. Are they semi or chisel?

 

[Bob Hedgecutter]

34- pass.
21= Oregon 0.058 doesn't it?

 

[ammoaddict]

Are you sure the bar is .050? The more I think about it I think 21 and 34 are both .058. Thinking 20 and 33 are .050.

You are probably correct with them being .058 . I went out and miked them. I was going by what was supposed to be original to the saw.
I did check the Oregon website but could not get any information on the drive link #'s. Possibly I was not doing it correct.
The saw was discarded because the chain was locked up. It may have been run with the chain brake on. . It showed signs of melting.
Compression is ridicules for a saw this age. A few pulls and it's purring like a kitten. A good cleaning and a new brake assembly and it's ready for a lot more years of use.

I like the 50 series. My first saw was a 50 in 1986. Still runs today. I have since acquired a 55 and another 50. Would love to have a nice 51.

This is my 2nd 51. I have a another 51 that's in fantastic condition. terrific saws.

I have a 51 as well - great saw, changed my setup to 3/8 low pro, sprocket , bar and new chain- Piked up a mint looking 42 special on the weekend and it will get the same, have a non-spur clutch drum and have loads of small bars, just my preference on my small saws, a lot of bars are stamped at what they need length, gage and drive links - but I do have a breaker and spinner setup which helps - this is only my preferance.

Thank You Ray

The 30 series is .325 low pro

 

[Franny K]

33sl an lg are the discontinued low profile .325 in 0.050 the sl has bumper tie straps.
34 and 35 are the same but 0.058 and 0.063 though I never had any 35 so not positive they offered it.
Oregon has removed the pdf files about the chains and their part or replacement parts # perhaps 5 years ago.

The 20 series is the current Oregon .325 for up to 62cc where the 95 is the NK good for up to 55cc.

Makes nice chips Chisel type cutters use an 11/64 size file or maybe the 4.5mm there may be a slight difference in diameter. Now Oregon only calls for that size file for their 90 class mini 3/8lp.
