husqy372xp2.jpg husqy372xp.jpg I got this saw off a friend who dropped it from a tree. Thought maybe the brake was busted but pulled it apart and found this. Is this worth ordering the parts (I'm guessing half of the frame?) or just parting out the saw? Everything runs fine except the brake assembly.
 
Looks like maybe it's broken, Jon. I don't think it'll buff out, either.
:D

Besides that, it's the wrong color.
:P

;)

Seriously, have you gotten prices on replacement parts?
 
I would get it repaired the 372 is one mighty fine saw. I think you could get a parts saw off ebay for cheap enough.
 
That's part of the engine case. Far enough away from the cylinder that tig welding is a possibility, but you'd have to strip down a bunch of stuff including the muffler and possibly the cylinder. There's ferocious force in that brake spring so it will have to be repaired very well or it won't hold.

Al Smith is the only one I know of on this forum who will say that splitting the case to replace one side is no big deal, but I've never bothered and probably never will. A couple others here have done it but at least they admit it's a major PITA. I'd rather swap the motor in my car than split open a chainsaw bottom end and rebuild it.

That's pretty much what I was thinking Brian. I got a price from the dealer around 180 for the crank case assembly but that's without the labor to swap it out.

jp:D
 
Either shop for a used bottom end and swap over the top end of this saw or else sell it for parts. He could probably get a couple hundred out of it as is if everything else is in good shape. Lots of guys out there would buy it to freshen up an old 372.

Or try the tig welding thing.
 
A good tig job on aluminum will hold under high stresses. I added to a piston skirt that way and it is still holding.
 
No I don't .I'm just an old fart that tinkers .;)

Now if you fly flea bay every so often you can find set of cases for that saw .As an example I found a complete bottom end for one of Toms 020 T's for about 50 bucks .About an hour hour and a half it was running like a new one .It's on the job as I type making him money .

Sure it can be welded but with the alloy used in die casting it's just plainly a beech to do .Even if you had to lay out as much as a hundred and a half you'll still end up with a great saw on the cheap .Now I'm talking a complete lower end now,no splitting just change the piston and cylinder . I'll take a little peek in a sec to see if there are for sale .
 
Price varies from 135 down with a crankshaft .A set of bare bone cases about 90 bucks give or take .I wouldn't get too hastey though because they appear quite often .

One thing about flea bay if you watch it long enough it will pop up .Too expensive just wait it out .Works for me and I'm tight as the bark on a tree .:lol:
 
I don't mind splitting a case, I've got the proper splitter tool. It takes time to strip everything down and get it all cleaned up to go back together. That's what usually kills the deal.

Like Al said, the alloy in those castings can be really nasty to TIG. Usually get a lot of porosity.
 
You'll have couple hours in it the way I do it with heating the case then freezing the crank and bearings on reassembley .Then though think about this model of saw which retails for 7-800 bucks new .Probabley fetch at least half or more used in good condition .
 
That case is Magnesium, not Aluminum, nasty stuff to work with! Soft and gaulding (plugs up cutters) and as abrasive as cast iron. Not to mention the flammability factor!
It can be welded, but make sure you have a really good welder doing it!
 
I don't have a heliarc rig and even if I did I have no experience on mag or diecast for that matter .The welder at work that did the cases on one of the 038 Mags had to use about three types of filler before he found the right one .That said it's not like welding aluminum plate because I can do that --if I had a rig .
 
I just brought my 272 and 372 to work for solvent tank cleaning and a little TLC.

Great saws. Worthy. Albeit the only worthy husky but whatever, I'm drinking beers.

A real good welder would be needed to do it.
Long ago I rescued a fellow loggers Husqvarna 266 from a burning lunch shack. The saw was on fire and there was no way I could save it, even after pouring 2 water coolers of water on it and a fire extinguisher. All that was left of it after was the crankshaft, muffler and b/c.
 
The water was your undoing, Willard! NEVER pour water on a Mag. fire, NEVER! It creates a chemical reaction and draws the oxygen out of the water causing the fire to burn even hotter! You have to smother it.
 
You're right Andy about the water, but the 20 lb extingiusher didn't work either. Is it true Husky has more magnesium in their XP crankcases then what Stihl normally uses?
 
Splitting the cases is a piece of cake without having to buy the special tool. Done enough now I'm tore down in less the 30mins. Dont need no special tools to put bearings or seals in and pull it all back together either.
Did bearings, seals, crank install on a 60cc poulan 365 in about 30mins to put back together. Used 1194 for crankcase gasket being there wasnt one from the factory, only sealant.
 
Not sure if it is different mix in general between Stihl and Husqvarna, but mix in Husqvarna saws is not the same in two models.
Alu/Mag mix is what is used in the cases to get it strong, but light. It is not often you hear of them breaking up by the chain brake. This one looks like it had help breaking.
Welding these cases is not easily done and in some cases impossible.
