3. Insert the press pin through the piston pin hole. Select the 

correct connecting rod guide pin (See above). Thread the 
guide pin onto the threaded portion of the press pin.

4. Position the piston assembly on the piston support in the 

press. With the press pin up as shown, insert the guide pin 
through the hole in the piston and through the hole in the 
piston support.

CAUTION

To avoid piston damage, the piston support must seat 
squarely against the piston. Verify that the piston pin will 
slide through the  hole in the  piston support.
5. Press the piston pin out of the assembly.
6. Remove the piston pin from the press pin.

2. 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.

3. Using the markings on the press pin, adjust the stop screw 

to the depth shown on the instruction for special tool 
MIT216941.

4. Place the base on press support blocks.
5. Slide the piston pin over the threaded end of the press pin, 

and thread the correct guide pin up against it.

6. Coat the piston pin with engine oil. With the connecting rod 

held in position, slide the guide pin through the piston and 
connecting rod.

7. Press the piston pin through the connecting rod until the 

guide pin contacts the stop screw.

CAUTION

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 if necessary.
8. Remove the piston assembly from the base. Remove the 

guide pin and press pin from the assembly.
