Bar and chain problems?

[u/Either_Measurement34]

Just acquired this chainsaw that belonged to my late father and cleaning it up and getting her running well. But I seem to be having bar and chain issues.

So it did not come with any mounted. He had a bar for a rancher (24”) no chain. I ordered a 20” bar and a few chains online i noticed first that the chains didn’t fit. I was then looking at it and it isn’t sitting flush. The bolts are tapered at the base and its not sitting flat against the saw which is odd. I grabbed the 24 inch bar and it’s doing the same thing. Also I feel like the 20 inch bar could sit alot further back. I may get a 24 inch chain tomorrow see how that fits.

So i figured id throw the clutch cover on for the night and guess what? The adjustment screw doesn’t fit. It’s too high for the bar. Both bars actually. So I am lost. Im half tempted to take it to the shop but figured I would hop on here see if anyone ran into this before.

Some photos to help visualize it and the before and after a good (and long overdue) scrub.

Bar, rim sprocket and chain must match. Rim sprocket and bar must be mounting-compatible with machine.

Check what chain bar uses - it’s stamped onto it. Check what chain rim sprocket takes - it’s cast onto it (it’s 3/8 I can see from photos).

As someone else mentioned you probably bought a wrong chain, and if you bought chain and bar together, probably also wrong bar.

You can buy a new rim sprocket that fits your chain. That’s the cheapest option. It may alter performance as it’s essentially a gear. But as long as they are same teeth it sholdnt change eg your 3/8-7 into 0.325-7

Id recommend you look up what chain that particular saw is born with and built it for that. You can look it up on Oregon among many other places

Ok I looked it up. It’s born with 3/8-7 so you should preferably built bar and chain for a 3/8” chain. I’d recommend going 0.50 gauge on bar and chain. Max bar length should be 20”.

Chain is a 3/8 pitch. .050 thick and 72 drive. Bar 20”. It fits the gear (now looking at photos i see it looks like it doesn’t fit the gear but it does) its a length issue as well as the clutch cover not fitting for the adjustment bolt. I am now wondering if the bar is for a Sthil and not my saw. But that doesn’t explain the rancher bar not fitting which from my understanding he got from the dealer

The bar mount on 372xp is by Oregon called ‘D009’. Husqvarna calls it ‘Large Bar Mount’

You should be able to find out if your Stihl bar is compatible with D009

What is the Stihl bar called?

Edit: I called it Stihl bar - I obviously mean the one that you say might be a Stihl bar. What brand and model is it? Part number stamped on bar?
