Homelite 245 .325 pitch chain

[cpotter0912]

A nice little homelite 245 followed me home today. Runs fine, but the chain was toast. So I get it on the bench and start tearing it down, I find it's got a .325 bar nose, and an 8 pin. This seems insane to me on a 40cc saw. It's a homelite bar and what I think is a homelite number stamped in the drum. Can anyone shed some light on this?

A 7 tooth sprocket would be better for general use. I don't see a problem with .325, as long as it's not full chisel or the depth gauges have been aggressively ground.

Why not full chisel? Does it not cut more efficiently than semi chisel? I don't run semi chisel on anything. When I look up parts I find only an 8 pin .325 sprocket or 6 pin 3/8LP sprocket for this saw.

Nothing wrong with really sharp super chisel. My experience with it on 35-40cc saws is that once it's even slightly blunted in dirty timber, what was a stream of chips becomes a sawdust shower.

Was on there as soon as I got the saw home. Shows .325 as an option on later saws it seems. Doesn't list a sprocket. My usual source for parts doesn't show .325 as an option but when I look it up other places online the only things I find are 3/8lp 6 pin, and .325 8 pin.

A79368 is the original part number for the .325 sproket.

The IPL shows they came with .325 or 3/8

I'm finding that too. Just seems nuts, the jump between 6 pin 3/8lp and 8 pin .325 is huge. Like I run 8 pin .325 rims on modified 50cc saws.

Hard telling why they did it. My 245 has the 3/8 LP. I put the louvered muffler cover on it and took out the baffles. Runs pretty damn good.

I do plan to muffler mod it. Maybe just being a lower RPM torquey engine vs the higher revving engines of today means it'll pull the 8 pin. But I mean, they offered it so it ought to. I put a brand new Stihl RS chain on it tonight, tomorrow I'll open up the muffler and see what it does.
