Bar and chain selection

I haven't seen this saw yet.

My brother said he's got a Jonered CS58 (Note. He wasn't at his saw when he gave me the model number. But said he thinks that's the right one).

He was either sold the wrong blade or bar (or both). None the less, he says it won't cut at all. So I'm trying to figure out how to get the right bar & chain for it, as if he just handed me the saw with no bar or chain. Start from scratch, sort of speak.

He says the numbers on the original bar aren't visible.

That works. Now does he know if he was running .325 or 3/8 setup. The bar can be anywhere from 13" to 20" in the .325 line or 16" to 24" in the 3/8" pitch and what gauge was the previous setup. can .050 narrow kerf, .050, or .058 on the .325 bar and either .050 or .058 on the 3/8 bar. Which make 24 possible setups.

So you got to put your hand on it and first find out which rim drive clutch setup it has. Then you can start figuring out which BNC setup you need or desire. Personally the 24" 3/8 bar would be a little too much for the saw. I think sticking with 18" would be better.

He's almost positive it's a 20" bar. He does have the original bar.
He says he's going to try and drop it off this afternoon.
 
To find the gauge of the BNC without caliper.

Dime = .050
Penny = .058
Quarter = .063 (be a little tight sometimes on new bars)

Just depends which will and which won't. IE penny and dime fits but not the quarter then it is a .058. In this case you it going either the dime or the penny as .063 is not available for this saw in BK095 mount.

It has a modified mount that is not a standard K095 but is a BK095 mount so a K095 bar will not work.
 
But half the time I can't the find them quickly. I usually have the coins in my pocket.

It like a dime placed across three rivets is a .325 pitch chain and nickle covering three rivets is a .375 pitch chain. These are the most common handheld chainsaw pitches.
 
Wish I had the room for multiple grinders but one has to it here, I use some of the space for the blade balancer.
