ricksrj58 273 #1 Posted April 11, 2016 i pulled the engine from my D200 and found 1 piston and rings had been replaced,but the other one had not and the wrist pin had some wear.that is where my knocking was coming from,so replaced the crank [ it had some wear also] and ordered new everything.k301 pistons and rings will fit this engine but as we all know the rods are NLA.i did find NOS rods on that auction site. my question is since the k301 pistons are the same is there not another engine that could have the same measurement in the rods?
