Chainsaw rebuild problem?

[Let her rip]

Hi forum, I am rebuilding an MS 460 with a seized up piston and from what I can gather the saw should have a 52mm piston but it has a 44mm one.... The cylinder head is an aftermarket Chinese thing from XinLei, and it says 52 on it, but the piston is definitely 44mm. Is it possible someone put the wrong cylinder and piston in it? The hole in the crankcase is definitely much larger than the piston. Any advice much appreciated!

Thats a China fake saw not a real or even clone 460. Thats why.

You been mislead lied to.

Thanks I did wonder! Nobody lied to me it was left in the house my friend bought after the previous owner passed away. Used it for a bit but it overheated and seized up, can get a cheap replacement piston and cylinder locally for peanuts and he can keep using it but I will tell him to go easy as it is not a genuine stihl

I wouldn't wast time or money on trying to repair. Something about polishing a turd.

Might be good for plastic parts and covers.

I'd clean up the cylinder, buy a cheap piston and a set of crank seals, and run it like you rented it.

I don't think so. Look at the photos. This isn't a clone of a real Stihl saw but a complete fake.

New piston and cylinder with gaskets is only $15 at my local store and will take me all of 20 minutes to put it back together. Will be fine for my buddy to cut up some firewood and do a bit of gardening until it breaks again. Will certainly recommend he buys a better one for the long term and not to spend more money on it though

But, but, but....it says "Made in Germany"

$15!!!! A 6-pack of good beer is almost that now.............ummm 6 pistons?

Who makes those and would it fit without getting "creative".

Need to know why the P/C toasted itself, unless it got straight gassed.

I forget the brand, I will post some pictures when I get it. The guy has a repair shop and uses these parts so there's a good chance they are reasonable quality knock offs. Should be a straight fit
It wasn't straight gassed I mixed the fuel myself 50:1. Burnt out after about 30 minutes cutting through some lumps of hard wood. Wasn't aware it was a fake stihl or I would have adjusted the carb so it didn't rev so high and not worked it so hard

That's about the size of it.

That's about the size of it.

Not even, the covers are completely different after looking up pictures of a real one haha. The only similarity is the colour

 

[Let her rip]

I do really appreciate the help by the way, I was so confused when I saw the size of the piston

So thanks

 

[irhunter]

I would get new crank seals, too.

And, run her at 40:1

To the OP: please report back after she's up and running.

First off, there is no way you'll be able to find, much less buy, actual parts for this thing. So, you buy a $15, 44mm piston. How do you know it will actually fit? Just matching diameter won't cut it.
Chuck it. Buy a real saw.
