Proline piston warning

[Woodslasher]

I was assembling an 056 with a 54mm top end, and I had a Proline piston on the bench that I was going to install. I had bought an 056 Mag II piston from them a few years back and it seemed to be close to oem quality. This one was packaged differently and had a bit of casting flash, which I cleaned up. When I went to install it, however, it has a good 2-3mm of side to side play on the rod and it is unusable. When I looked at the box, the Proline label is slapped over a generic "white box" label, similar to the ones you see on LRB piston boxes. I will be doing what I should have done in the first place and ordering a piston from The Duke, but I wanted to give y'all a heads up about this issue first.

Thanks for the heads up! Ive never tried one of their pistons but I have used The Dukes coated pop ups before.

Well, The Duke’s piston is exactly the same as the Proline except for the coating. Looks like I’ll need to retrofit a different piston!

I wish hyway had a larger selection for older saws

What MM is that saw?

What MM is that saw?

54mm, I have a ported 54mm jug destined for the saw I hope. If not I may grind out the holes in a Mag II jug so it'll bolt on to that chassis.

How about spacers?

That'll be my 3rd option, using a 288 or 066 piston may be possible so I'm exploring that route first and the 56mm option will be my second choice.
