5/32 or 7/32 file
« on: March 08, 2016, 09:10:58 pm »
  I have a Craftsman 3.7 , ( Poulan 3700 ).  Got it used, came with a 7/32" file and guide, original 18" banana bar.  Put a 20" Oregon bar and chain on it, literature said use a 7/32 file.  It is 3/8 pitch, .050 gauge. Today I found a manual  for it on SearsParts Direct. Reading thru it, it says to use a 5/32" file.
  I have another small Craftsman/ Poulan with Lo Pro 3/8" chain ,.050 guage and it uses a 5/32" file, So what is the proper file to use on the  D70 Oregon chain on the 3.7?

.440 chain uses a 7/32" file
Regular 3/8" chain uses 7/32" file but the Stihl book calls for 13/64" file on regular 3/8 pitch RS/RM chains but I just use 7/32" file on them.
.325" uses 3/16" file
3/8" low pro or pico uses 5/32" file

660Magnum, thanks for clearing that up. I've been using 7/32" file  since I got the saw, so I was surprised when I read 5/32" in the Sears manual.

660Magnum, I finished reading the Sears manual. The 5/32 file was recommended for the Power Sharp version.  oops.   I have the non PS version and it recommended a 3/16 file.
 I have the original banana bar and chain and the chain seems to be heftier than the newer chains. I'm still mastering the art of hand filing. I'm sure I'm not the only one that has a hard time keeping the left and right cutters even.
    In the accessories section I noticed a chain (76LP-66) that does call for a 7/32 file.  So are there more/less aggressive chains that would use a different file while the pitch and gauge stay the same? Or am I over thinking this?

The Powersharp is a different animal from regular chains

I just use files like in my previous post.

You mean 76LG?  Not a 7/32 file either.

I just reread the manual for my saw, 358.354830 on SearsPartsDirect and it did say 76LP under accessories. It said requires 7/32 file. What is the difference between 76LP and 76LG?  I checked out the 76 chain thread also. I have alot to learn about chain.
 Thanks for the responses fellas.
