ok caz im sure i would have to ask 6 diff ways i got a pic how do you get these pins out? is drilling the only way?

(by these pins i mean all of them not just the 3 that are marked)

 

Why?

 

caz i thought there might be a diff way to get the pins out. with out drilling

 

So he can add a piston in its place, thats why.

 

They are not supposed to be removed, unless you're making a clock.

 

^^^ lol randy your funy but dont give away all my secrets.....

caz im wanting to remove the ring

 

i know this or if you are going to have the gear cryo treated..and are going to tap the holes and use a lock screw to hold them in place so they dont try to get loose in the high rpms

but yeah we will say a clock is the only reason you would want to remove them

 

There is a thread discussing roll pin removal for the exhaust sleeves. Find that, it should give you a lead on removal. Process should be similiar.

 

thanks trochoid

 

Go over to nopistons and post this in the porting forum or on the performance forum here. You may get some hits that way.

 

BDC has a write up there, I think, Engine Building and Porting Section. that's how i finally got mine out.

You will probably need to use the screw method, I don't think you want to try the welding one.
