I have a friend who works a municipal job and they are always updating saws and when they do they leave behind chains that don't fit. Some are new or like new. I have two saws I use, one uses .325 the other 3/8. How can I tell what the chains are. Mostly Oregon. For instance one says 33 and one 34. Is there a book or something to help?

The 33 and 34 are both a .325 chain. The 33 is a .325 with .050 thickness drivers, the 34 is also .325, but has .063 thickness drivers. The 33 is the most common .325 chain, the 34 is mostly used on stihl saws, they are the ones that use the .063 chain. now there will be letters to designate if it a chisel, chipper, safety, semi chisel, skip tooth, etc.

The 3/8 chain comes in 2 sizes, the 3/8 lo pro , in Oregon is a 90 or 91 designation. the 90 is .046 and the 91 is .050.
The you ahve the full size 3/8, it is designated with a 70 series, again depending on the drive width, then again all kind of differant letter denominations depending on the cutter type and style. Is this all clear as mud now?

Ya can get lots of info on Oregon's web site, link below. For getting started there is two important things about saw chain, the bottom, so it fits your saw bar and drive spocket, and the top, which determains how it peforms in wood. 3/8" or .325 refers to the pitch, or distance between the centers of the rivets. Gauge is the width of the drivers. Most chain designs are now offered in saftey chain (low kickback) and "pro" chain that lacks kickback protection. Past that there are different kerfs (width of cutters) and different cutter profiles such as chipper and chisel and square ground and round ground. All this adds up to it would take a pick up truck to hold all the differing chains offered by any one Mfg let alone all of them. If you are competant and enjoy your saws it is amazing how fast a saw will cut with a nice full chisel pro chain from a saw shop as compared to the safety chipper chains sold at box stores.

To tell ya the truth. Take your saw and thoses chains to a saw place that makes chains. The size 3/8 covers several types of chain. There is high prohile or standard. The other is low prophile or 325 low kick back. I hope I have this right cause there is a boat load of sizes and types. Low kick back or chisel or chipper or old style rip. The list goes on and on. Also Oregon, Still, Carlton and others use differant numbers for the same chain. You will also find there are a couple of groove slot sizes. Just for fun tell the guy you know someone who has #6 chain. Try playing with the three big toys I have. Mall A2 with a 9/16 pitch chain. Mall model 11 with 9/16 sideplainer rip chain. The big beast is a Disston KB7A two cylinder 12hp with a 3/4 pitch chain. My McCulloch 650 only needs a 20 inch bar with chip chain! The dealer will be happy to tell you all you need to know. Go to a Sthil dealer and by a couple of chipper chains. They cut like the hot knife in butter, but BE CAREFUL till you get the hang of how fast they cut~!!!! Jeffcat
