Hi there, through past experience of getting your 2 pistons into the Puch barrels is a precarious one,lots of weight especialy with the SGS barrels and with brittle rings ,broken ones are often the result :oops: I have just restored my 175SV motor and thought i would show a failproof way of doing it!! only downside is the motor has to be out of the frame . more photo's at www.berniesbikeshed.wordpress.comhttps://berniesbikeshed.files.wordpress ... 1024&h=683 :lol: https://berniesbikeshed.files.wordpress ... 1024&h=683 :P https://berniesbikeshed.files.wordpress ... 1024&h=683

Yeah, it's not a easy task to get those piston in place. But if the motor is in frame it's posssible to take one piston at a time, staring with the front. I'm looking for a 42mm std piston, and wondering who is Gerd Krauter? :)

I just insert the pistons into the barrels with the cylinder on the bench and then I just slide the piston pins in..

once the pins are in you simply prop the barrel on something of correct height (2 bits of clean 2x4 cut to the correct height) then just instal the circlips, pull the blocks apply gasket sealer (I dont use gaskets) and then drop it down.

thats the easy way for me to do it by myself.

edit: haha oh I just looked at the pictures
