Can someone tell me the difference and what the advantages or disadvantages are between bushed or pressed? Why does it make a difference?
thanks ..

Connecting rods that are designed for pressed pins have a smaller end diameter that is actually smaller than the wrist pin diameter. The process of installing a press fit wrist pin usually involves heating up the rods then inserting the pin. Then you allow the rod to cool and the contraction will hold the pin in place while being pressed.
If they're made for a full floating wrist pin, then the rod will have a bushing in the end that is honed about .001" bigger than the diameter of the wrist pin so it can rotate in the small end of the rod. Full floaters also have an oiling hole drilled into the top of them to allow oil to get down onto the wrist pin and allow it to stay lubricated. Full float pins use spiro-locks.
Full float pins, if installed correctly, will handle more power and higher RPM's better. -
thank you very much Kevin...
great response... you helped me out a great deal here ....
