>> A << Piston Pin Installation
WARNING: This page is about a different variant/trim than selected.
- When replacing the piston pin, read off the cylinder bore size mark on the cylinder block as illustrated, and select a piston according to the flowing table.
NOTE: The piston size mark shows on the top of the piston.
- Thread the stop screw and lock nut assembly into the base. Fit the correct piston support on top of the base. Insert the press pin, threaded end up, into the hole in the piston support until the press pin touches the stop screw.
- Using the markings on the press pin, adjust the stop screw to the depth as shown below.

- Depth: Refer to the operating instructions on the special tool.
- Replace the base on press support blocks.
- Slide the piston pin over the threaded end of the press pin, and thread the correct guide pin up against it.
- Coat the piston pin with oil, and with the connecting rod held in position, slide the guide pin through the piston and connecting rod.
- Press the piston pin through the connecting rod until the guide pin contacts the stop screw.
- Remove the piston assembly from the base. Remove the guide pin and press pin from the assembly.
- IMPORTANT: Due to production tolerance variations, it is necessary to visually inspect the piston pin depth after installation to verify that the piston pin is centered. Adjust it necessary.
- Check that the piston moves smoothly.
