Pins fitted to pistons in southern California and the sent up to the northeast during the winter where often very difficult to remove often needing heating of the piston to get the pin out. If you bring your rods to a machine shop to be honed be sure to bring two wrist pins. If the shop is properly equipped they will have a fixture that holds two pins and then is used to set the AG300 gauge. The proper hone has bronze shoes not the aluminum throwaway type of hone. Proper fit is usually .0003-.0005. a few strokes with a fine stone will do it. There is enough variations in wrist pins that this may occasionally be needed. No big deal. Model As have full floating pins.
