Chainsaw Repair

A lot of chain, including some Oregon and STIHL models, use a thicker drive link (.063, or .058) that is thinned down to fit in narrower gauge bars.

This is why, for example, you can use the same pre-sets for many Oregon .050 or .058 chains.  Not usually a problem.

For this 3/8 low profile chain (similar to type 91), Oregon doesn't make a thicker gauge version, so the pre-sets were only made to fit .050 chain.  Oregon does make a thinner version (type 90, .043 gauge), and I see that Bailey's stocks separate pre-sets for those.

The Carlton N2C chain was also 3/8 low profile, .058, but is not listed in the current catalog.  Fortunately, my local dealer has been in business for many years and has an eclectic stock of parts.
