Chainsaw Repair

Well first off 3/8" low profile and standard 3/8" are not one in the same .Nothing interchanges to make them work .Not the drive sprockets the bar nose sprockets nothing .Even though the terminolgy of "3/8" is misleading it's one size below .325 .


To make it more confusing 3/8" low comes in two different guages ,.050 and .043 .Then again .325 comes in .050 and .063 maybe .058 for all I know .Driver guage seems to be a regional thing with what is the norm or popular  in a praticular area .


You want to really get confused try .404 .Heavy chain used normally on over 100 cc saws ,usually in .063 guage .That 48" hardnose on the saw in my avatar is .058 .

I have a 32" bar on a Mac 805/850 that originally had a .404 nose but in .050 guage .I changed it to 3/8" standard.
