Last winter a do a rebuilt on my B18C motor.
Buy SRP forged pistons to raise compression (JE). Part # 149212
This winter i disasemble the block to do a check-up and install ARP rod bolts.

Bad surprise to me, the wirst pin is blue and the piston hard to move on the rod.





the pin come with the piston from ARP ans it's perfectly correct when assembled.

What i need to do? any king of warranty by SRP/JE?
Clean up the hole in the piston with a brake cylinder hone and put fresh pins?

The pin is press on stock B18C rods

 

What was the clearance when you installed them? Press pin and full "floaters" have different numbers.
warranty amounts to problems when purchased, not afer using them.

 

I use the pins comming in the box with the pistons and rings.
Noting in the instruction sheets specifie different pins for press fit rods.

Pins # 827-2250-15-51S

clearences between the pistons and pins?
pistons to wall was adjust to spec when honing the cylinder.

 

I did not say different pins. You bought something for a "floater" design rod and changed ther use, then you are supposed to know the clearance and how to adapt them to your application.
