McCulloch Chain Saws

[Maintenance supervisor]

Hi guys,
Just bought a pro-mac 10-10, B&C are complete rust so i cant read all the infos on the bar. I wanna know what sprocket size I have to put a new B&C and if possible dont want to remove clutch drum.
Im betting .325 but not sure. Thanks !

Btw, she has not run for more than 15-20 years the seller told me. Carb cleaner in the 3 adjustments screws holes, flesh fuel and she run again. It amazes me everytime

Bar is oregon 1650 1714UQ

It's probably 3/8 chain.

That drum is a 3/8 pitch (.375) 7 tooth.You could probably clean up that B&C by soaking it in some kerosene or diesel fuel & then take a wire brush or wire wheel on a drill to remove the rust.PB Blaster works good too,it just takes some elbow grease & patience.

The clutch drum shown is splined and would accept a variety of rim type sprockets so your options are wide open.

Thanks guy. I had a B&C in 3/8 that was on a 266xp. Not sure the oiler hole are directly right but gonna try it.

I thought about that too but the bar is broken, there’s a big piece of the bar missing at the nose sprocket. Thanks!

Hi all,I just got another 610 going again.I picked it up for $25 & it's been sitting in the garage for the last 3 or 4 months.Since I got the other 610 going the other day it must've lit a fire under meI threw a rebuilt carb in it that I've had on hand along with a newe plug & a few pulls later it was running beautifully again.I put my last 20 in B&C on it & took it over to the wood pile for a test cut.It cuts nicely,but the chain needs to be sharpened.
I pulled another 610 out of the garage & it's a good thing I did because when I pulled on the recoil it didn't want to turn over.I thought maybe the recoil was buggered up,but after I pulled it off I still couldn't turn it over by the FW.I put a mix of 50/50 tranny fluid & acetone into the cylinder & let it soak.I found that one of the pawls & spring was broke.I had an extra one of each laying around from a 610 I worked on over a yr.ago & put that on.I got the engine to break free & after a while it's got compression like a new saw.I saved it! Tomorrow I'll see if I can get it to pop,but that migt prove difficult because of all the oil in the cylinder.

You could fimd the replacement nose and I soak my rusty bars in white vinegar and water for 2 days and the rust wipes off but you HAVE TO oil it immediately.

Does any company make a bar blank you can buy and machine yourself?

You could ask "Chain Bar Repair" in Portland Oregon.

or they'd likely make whatever ya wanted.

I checked the cannon website and it seems that they'll only go back so far and then your S.O.L.

What saw you need a bar for? I'm sure something must be close enough to adapt surely

1-41 mac

Pretty sure there a heap of options for the large frame. I see bar spacers mentioned a lot for a slimline bar. If the bar stud slot is too narrow a 5 inch grinder could probably do the heavy lifting and then finish with a file. Slog out the adjuster holes to where you need with a chain file or dremel.

 

[heimannm]

I have an ample supply of 18 - 20" hardnose bars for the large frame McCulloch saws if you want to go that route.

This is the bar and chain I have for the 1-41 , you can see the nose is pretty wiped out and I'm not sure whether chain is even correct.
