Fitting Piston Pins: Installation
- Check piston-to-cylinder bore clearance before assembling piston and pin to connecting rod. Ensure oil hole in connecting rod aligns with oil hole in bearing (and arrow or notch on top of piston is pointed towards front of engine). Start piston pin in piston and connecting rod.
- Using guide bar and push rod, press pin through both piston and rod until pilot hub bottoms on support fixture and pin is centered in piston. After pilot hub bottoms, do not exceed 5000 lbs. (2275 kg) pressure with press. Make certain piston floats during pin installation operation.
