Installing New Piston On Viper????


new wrist pin will slide in , it might need a gentel tap , but no press needed..
 
Your wrist pin should slide in. As for your oil pump, while holding your throttle wide open pull your oil pump cable out , the top edge of bottom half of the adjuster should center up on a dot on the top half. I'll try to get you a picture. There is also a millimeter measurement for between the two halfs when pulled apart which is 21mm or 7/8", if you use this method you do not hold the throttle open .
 
Thanks guys!!! still not sure where to measure the 21mm from is it the adjuster up from the bracket ///bracket to the adj nut 21mm???
 
it's the distance of the space, when you pull the adjuster part of the cable apart. the lowest part of the upper section and highest part of the lower section
 
if you have trouble with the wrist pin, get a piece of threaded rod and a 15mm deep socket, run the threaded rod thru the socket and the middle of the wrist-pin, thread a nut on on the both sides. then tighten the nut at the end of the socket, this will pull the wrist pin out "straight" takes a couple more minutes, but if you're having trouble, it works every time. (especialy handy when the ring land is collapsed, or there's shrapnel that has deformed the pinhole.
 
Looks like this;
