Does anyone know what the filing angles should be for an Oregon Type 61 .404 chain? Does it take a 7/32 file?
Wow Ray, knowledge you shared on here 15 years ago just helped me figure something outOregon 61 series chain is 7/16" pitch, use a 1/4" file.
Oregon 51 series chain is .404 pitch, use a 7/32" file.
