Husqvarna 50
« Reply #1 on: April 22, 2011, 01:41:28 pm »
so i have this husky 50 sitting here and it needs a piston. was figuring on putting a stock piston back in as the cylinder is still near perfect and the rest of the saw is in fairly good shape save for the brake handle and clutch shoes.
the saw runs (albeit rattles like a can full of rocks) good, will cut well and still has good power. the piston is WAY WAY worn out, but the engine will still blow 155psi all day long :D just makes alot of slap slap slap sounds when running.
the person i bought it off of for parts said the crank was bad. when i tore it down i found the piston ovaled nearly 18thou and with a good belly half way up the skirts ;D
i "think" it's a45mm'er but the vern. caliper i'm using says i'm just shy of 45mm buy about 1/3 a mm at just above the pin.
of course the piston and cylinder are at home. so i can't check until tonight. same for the serial#.
was bought new in 1989, has that horrible squish the filter to choke mechanism......
sooo, what other top ends will fit on this saw. part numbers would be fantastic! thanks. 8)
when I grow up, i wanna be an adult.

I had read somewhere that husky 50 had 2 different cyl bolt patterns for early and late. You know anything about this Spike or others?  I cant get the pdf file to open that it was in to post for you.

But on the later I think you could put 51 55, 500, 490, 590, 5000, 5000 plus and 325 5500 540 on. Check clearance for the 46mm ones.

Some dealers used to put the 5000 top on a husky 50 to make what is called a 50 Magnum.

(Back in the 80's we were selling a Husqvarna 50 Magnum. This saw was created in Charlotte, NC by the Husqvarna Distributor owned by Jim Thompson, The guy that made Husqvarna as far as I'm concerned. They brought in Partner 5000 cylinders and pistons and put them on 50 Rancher (the old white top) saws. These saws were awesome. The first one I received we got out of the box on Thursday and blew the competition out of the water on Saturday at the Races. Back then we had Chainsaw competition's on monthly bases. Husqvarna Sweden made them stop building them in the states. We built some ourselves after they stopped. It was a simple bolt on with no modifying at all. Someday I'll tell you more about the old Husqvarna distributors that made Huqvarna what they are today.)

I know a couple guys I traded my NOS and used ones off to already.  ;D

I think I only have 3 top ends left and they are on saws right now.

thats o.k., i'll give you a couple minutes to go grab one for me ;D
sawtroll figures it is a 45mm. i tend to agree as my vern. was showing the piston slightly bigger than 44mm.
i might just throw a stock piston in it and run it. also needs clutch shoes (they're missing about 1/8"--yes an 1/8" dia). they still grab good but the spool up time is looong. and the brake handle is broken at the top. nothing major. everthing else is in good shape for the amount of use.

Well well, isn't this a timely thread.  8) I have a pretty nice 50 gray top that is going to be my next project. It's an '87, so that would make it a 44mm. The switch to the 45 came a couple years later. I wouldn't necessarily assume that the cylinder change coincided exactly with the corresponding change in the case, but I doubt that I'd be able to put the closed port 55 jug on there. But I did want to juice it up somewhat.

What I do have, (and never gave it a thought til reading this thread), is a good Jonsered 490 top end. The 50 is not a bad destination for this jug since I busted off the top mount bolt when taking the 490 apart, so I won't have to screw with drilling it out.  :D

I'm going to stick with the goofy choke and filter set up cause I want to stay with the gray top look and besides, that will make it more of a sleeper. Do a compression bump, muff mod. Guess I'll be building myself a 50Magnum.

Not aware of a different bolt pattern for these saws. Maybe something on the earliest white tops? I'll do a little research and see what I can come up with.
