i have old cylinder lying around it says 45L stamped on top is this 45 mm it has bore size of 1-3/4 or 1.775 with mics thanks what size piston do i need is what i am asking . i think 45 mm if you convert from thousands it is 44.45 mm ?
there are two sizes of piston for that saw, both 44mm and 45mm. I would think that yours would take the 44mm piston based on that measurement. Or buy a new kit that has both cylinder and piston together, might even be an upgrade in power for the 45mm kit.
Do you have the old piston? The "dished" pistons are 45mm.
Also, I have yet to see a cylinder marked 45L that did not have a 45mm bore.
Might be coincidence...might not.
