I took some pr3 (b16) and pr4(ls) pistons on rods to get swaped over at a machine shop. They said they couldnt do it cuz pressing the pins out would wreck the pistons.

Even if he made a jig he said it would still wreck the piston.

Any though on this?

Trying to ls/vtec

 

You can't reuse pistons once they are pressed off. The machine presses on the piston to remove the wrist pin, thereby making it useless. Hav eto use new pistons and pins

 

There are tools available that place the force onto just the wrist pin, but even then there's still a chance of warping and breaking the piston.

 

yea there just garbage i just got this done like 2 weeks ago...2 other shops around ehre wouldnt do it but this guy did and only charged me 30 bux

 

anyone else?

 

its a chacne sometimes they come out ok and sometimes they dont.

 

i had it done, the machine shop said that it could possiblly mess up piston.it work just fine for me p30 pistons on ls rods, paid 25 dollars the best 25 dollars spent, i guess i got lucky
