Title: Husqvarna 41 oil tank leak
Post by: lowvirtualmemory on April 25, 2017, 11:18:46 pm
Howdy, all. 

After looking through many of the stickies and running a search through the Husky 41-specific threads, I decided to go ahead and see if anyone could offer some advice concerning my model 41 Husky. After years of faithful service, it developed a split in the oil tank housing, right along a casting mark / line in the plastic housing. After a couple of attempts at cleaning the area and sealing it with JB Weld and Seal-All, I have decided to give that approach up and seek a replacement housing to fix the problem. My specific question is this: Does anyone know whether the model 41 housing will cross reference / swap out with the model 141, 142, 36 housings? They look pretty close in size and configuration, etc. If anyone has any info or thoughts on the matter, I'd be obliged.

Thanks for your responses, Cut4fun. I've saved a couple of the eBay listings that display a singular Husky crankcase housing but multiple crankcase #'s (36 41 136 141 142) and queried both sellers as to whether the one housing will actually fit multiple crankcase model #'s of saws. I'd looked on eBay and Craigslist the past few months but hadn't found anything suitable, at least price-wise. Some of the housings approach asking prices that make me consider whether to just invest the money in another used but newer model saw of similar size. The aftermarket Chinese housings look tempting price-wise, but I'm sure I'd regret going that route as far as quality, fit, and potential cracking / splitting again.

In the meantime, I've been using my old red vintage Homelite XL. It really makes me appreciate how much faster the engine runs on a Husqvarna saw. The old XL does smoke heavily enough, however, to keep the hordes of mosquitoes away while I'm clearing brush.

I like this stuff over JB weld you tried.  Try roughing the area up.  Work up some QuikSteel putty up mixed real good in hand like putty. Then put into area. Let dry 24hrs IMO and then coat that with Seal-All.

I have done this on chainsaws and a plastic gas tank on my own SUV and still holding till this day.

I use the steel and they also have a plastic. Never used the plastic to say. http://bluemagicusa.com/index.php/blue_magic/category/27/

I can't seem to work up much enthusiasm for trying to re-glue, unless I make a winter project out of it or something. I did rough up the area with fine grit sandpaper and even tried some PVC primer (lol) as well. out of desperation. Never seen the quick steel epoxy before in my area (eastern KY) before, don't think. I'll look for some the next time I'm in the vicinity of an HD or maybe A-Zone.

There's an older Echo saw, plus a couple of the PP 42cc saws for sale in my area. Echo is a good saw, I believe. I used to have an Echo weed trimmer, and it was outstanding in every respect. I think Echo and Shindaiwa are both made by the same manufacturer in Japan. Don't know a whole lot about the newer PP's. Used to have an older used one, years and years ago, that wasn't much. But I think it was one of the smaller, junkier models, about 32cc's or so. d But did'nt I read somewhere or other that the PP Pro line are now made by Husqvarna or Jonsered? If so, might be worth looking at or trying out. Still a doubter about Poulan though.

Clean all the glue and oil off and out of the tank and case. Use a good hot soldering iron to reweld the seem back together. Go past both Crack ends to make sure you stop the Crack from restarting. These little saw just are not worth tearing down as you'll have 50 other problems after you put it back together.

Thanks for the suggestion. Using a hot soldering iron to reweld the crack seam is something I hadn't thought of. I think I might very well try that one. If done properly, should the weld / melt seam repair be flush with the surrounding surface, or will there be a depression / groove along the repaired seam? If the latter, should that then be surface coated with an epoxy product, such as the QuickSteel epoxy, do you think?

Yeah, it's probably borderline whether the model 41 is worth much more time and effort to get it going again. I guess it's the "raised poor" frugality in me that makes me want to try again, plus I hate to junk out a saw that was running & cutting fine just because of a crack in some plastic part. But regardless, the 41 won't be my go-to saw around the home again, even if repaired. Just an occasional use backup saw.

I have a 41 here and I had the same thing happen so the tank.
Jfyi
Used 41 crankcase https://store.chainsawr.com/products/husqvarna-41-chainsaw-crankcase-chassis-with-bar-stud-set-2

is on the saw I have and the saw is handy for a limbing saw even if its a poulan in pumkin with a gray top. for what it cost me was the parts may be $35.00 I like cheap saws when I can find them and dont coast mush to get running again.

Thanks for your feedback, bill. The smaller model Husqvarna saws of that series and era seem to share the "cra cked tank" syndrome from what I've found. I found the "soldering-iron weld" repair posted recently by brokenbudget to be rather intriguing, and I think I'll try that particular one next (after gardening season is over, lol!) rather than attempt another one of failed "glue" repairs. I don't really care how the finished repair seam looks--I just want it to be a successful one so that the saw is functional again. I have cut an absolute TON of wood over the  years with it--quite a few large, standing dead oaks and hickories that approached 30+ inches in girth. For such a relatively small and inexpensive saw, it has been a heck of a worker that deserves a better fate than being junked out because of a cra cked plastic oil tank.

I quite agree with you on liking "cheap saws," bill, particularly since I'm not a materially well-off man myself. And some of the "cheap" saws I've had in the past--an old beaten-up Homelite XL and Poulan Pro in particular--have outlived and possibly out-worked my neighbor's high-end Dolmar model(s). Plus, cheap saws also make good wheel-scotchers for an old truck with a weak pressure plate / clutch when parked on a hillside....
