510 Te Model 1984 Looking For 2. Oversize Piston

Hi everybody,

my name is Günther and i'm an old man from Germany. I recently found a Twinshock Thumper that has to be rebuilt.

Cylinder / Piston is worn, so i have to go to an 92,00 mm bore. But at the Moment nobody in Europe (not even Andy at hva- factory) has a Piston that size) .

Maybe anybody knows, where or from whom i can buy one.

My englisch ist a bit rusty, so maybe i can refurbish that also

Welcome Gunther, I'm not very familiar with the 510TE, my interest is primarly in 70's stuff. Of all the Husky sources I've dealt with I've never seen any info on a piston for your thumper. Maybe someone will respond with an idea.

Wossner makes the pistons for the water cooled 510's. I not up to speed on the 510/4 stroke Huskys. Maybe the water-cooled model piston will work for the air cooled motor? Compare the wrist pin sizes and the stroke and compression height.

Here is a link to a new Wiseco piston on Ebay. This one should do it and they have it in the size you need.

Hi Marty - yes -that's what i need - thanks for your support

pistons for the water-cooled Models are different because the cylinder is nicasil- plated.
Air cooled cylinders have a cast sleeve.
So piston rings are different - depending on the material of the cylinder, also the thermal expansion of the piston should be different

But the tag on the box says 1983 and from the looks of the tag I'd say it a Wiseco tag so it looks like what you need. Theres always risk when buying parts for a vintage project.

the linked piston should bei the right one.
I Just wanted to explain, that early air cooled 4 strokes
need a special piston and can't use those for water cooled motors.

I wasn't aware of the difference, thanks for the heads up.
