In reply to TVR Scott :
The two black plugs you can see on the front of the block allow access to the wrist pins. There's two more on the back. You just remove the plug, remove the spring clip and then pull the wrist pin. Then you can replace the piston without any further disassembly. No torque to yield, in fact, no torque at all and the pistons I got are direct drop in. Easy peasy.
