Glanzacoley Posted September 4, 2014 Posted September 4, 2014 Anyone got any tips of how to do this? Many thanks?? Quote
5e colin Posted September 4, 2014 Posted September 4, 2014 be sure the piston is level and supported propper or it could crack bets to get it done by some1 that dont it before Quote
Glanzacoley Posted September 4, 2014 Author Posted September 4, 2014 Does it need to be pressed out or is there a circlip or just knock it out mate? Quote
FMuscle Posted September 4, 2014 Posted September 4, 2014 I use a 19mm deep socket with strategic cuts on the end to support the pistons. You just need to make sure the socket is deep enough not to get the pins stuck in it... <Been there... Quote
Chops Posted September 5, 2014 Posted September 5, 2014 One method is to find a bit of tube with the inside diameter matching the outside dai of the piston and drill a pin sized hole right through the centre of it. then sit the piston in it rotated to line the pin up with the holes and use a piece of bar ever so slightly smaller than the pin to knock it through. serious care needs to be taken with the whole thing, its a massive ball ache. hitting the end of the rod with a torch can help to loosen the pin too, but its not amazing for the structure of the metal.

Ricky@Race-Tech Posted September 8, 2014 Posted September 8, 2014 We have a jig for the press that supports the piston completely. We charge £10 per pin plus postage. RegardsRicky Quote
Phil Posted September 8, 2014 Posted September 8, 2014 so stock pistons are semi floating press fit gudgeon pins? never realised this, use to take this out and fitting new shiney forged fully floating circlip jobbies. BUT recently bought some pistons and they seem to be pressfit/ interference pins which is abit confusing to say the least. odd for a forged piston! Phil Quote

Phil our stock piston and rods are pres fitted on the rods and floating on the piston phill stupid mistake from toyo :) ha ha Quote
Phil Posted September 8, 2014 Posted September 8, 2014 Those SPS pistons i got off browner have no space for circlips so must be press fit (or else they are expensive paperweights lol) unusual on forged pistons. Phil Quote
