Does anyone have a trick for installing the pistons into the cylinder bores on a 750 maxim?

Hi Housedoc,

become an octopus ! but seriously if you dont have access to 2 sets of ring clamps you will need 3 people.

1 to hold the cylinder & the other 2 to compress/feed the rings into the bores. without clamps & the engine in the frame is difficult but not impossible.

Starting with cyl #1 & #3 at tdc compress the rings by hand as someone drops the cylinder by hand (best to have the cylinder held just above the top ring) SLOWLY drop the cylinder while you check & feed the rings into their bores. As soon as the rings are in the bores turn the crankshaft so cyl 1 & 3 go down and 2 & 4 come up the meet the cylinder and repeat the earlier instruction.

When all rings are in their bores tap the cylinder down, making sure the bottom of the bores do not foul the base gaskit and the cam chain is pulled up it's channel. heypresto the cylinder is fitted.

If you have compressors (like the Yamaha ones) This job can be done single handed, if you need info let me know
