    I'm a firewood hack who likes saws. I’ve been rebuilding Husky’s of late and have this 372 on my bench. It’s got a great top end, bearings feel great but will most likely get replaced with the seals and fuel lines. That being said it suffers from case damage. How would you all repair this or would you? Is epoxy an option or would it have to be welded? Or new case halve? Thanks for the input. -Bob.

    Welcome to the site
    It could be welded or the case half replaced
    Easier if you don't have anyone
    To weld it.

    Looks like the brake handle mount hole is wallered out too. I’d replace the case half

    Believe it or not the brake handle hole still has usable threads. Does look funky though!

    I’ll look for a used case half or whole one if I can’t get it welded.

    As for welding, is welding the magnesium alloy much different than aluminum? I have access to some really good welders but I would wager none of them has welded magnesium alloy.

    Thanks, Bob.

    If you are doing bearings for sure .. then a different case might be logical You will have to save the old one to qualify for CAD benefits some one may come along in the same situation as you. Welcome to OPE

    I can weld it, but it will need to be broken down to just the case half as I'm all but certain I'd burn the case gasket welding that much material.

    Lots of options here, I would take into consideration the condition of the rest of the saw and what type of service would the saw see after it's repaired. If the saw has a bunch of other needs a parts saw might be a good option. There's used and new cases as well as the aftermarket cases. The popularity of this model should mean a good supply of used stuff out there. Welding can be a great option and has saved numerous saw's from the scrap pile. A case half would be my last resort as they don't always have the same deck heights, doesn't mean it can't be done, it just means there may be more to it than just a simple replacement. Also don't forget about the red headed step children out there, a little orange paint can put a Jonsered part in service if that's what you can find by chance.
    Usually if you are flexible and patient, the right thing will come along.

    How many colors can be put together on that model or type of saw? 4-5?

    @srcarr52, yes it’s getting new bearings as this is a 2011 x-torq. Other than the drop damage it’s in good shape. Looked at your work, very nice and that’s coming from a metal fabricator/welder from two decades ago. I am versed in TIG/MiG/stick but never did much of anything with aluminum and no longer have equipment. I do however manage 2 dozen contractors. Half of them are welders but again not much aluminum mostly high purity piping orbital and tig. I’ll see if any of them are up for it. Appreciate your offer but in these crazy times I Probably won’t be shipping anything soon.

    @Stump Shot,

    I’m a firewood guy who already has too many saws! Just like working on them. I have another 372 as well as a 362xp, 359 and Dolmar 6100 in rotation. In other words I have no reason to be in a rush!
