#### Tools Required

• | J 24086-C Piston Pin Remover/Installer

• | J 24086-150 Fork Insert

• | J 24086-900 Universal Fork

Caution: Wear safety glasses in order to avoid eye damage.

Notice: After the J 24086-C installer hub bottoms on the support assembly, DO NOT exceed 35,000 kPa (5,000 psi) or the tool may be damaged.

Important: When assembling the piston and connecting rod, the mark on the top of the piston must point to the front of the engine block.

The piston pin has an interference fit into the connecting rod and is full floating in the piston.
1. Install the piston pin and connecting rod assembly.

1.1. | Lubricate the piston and connecting rod pin bores with clean engine oil.

| Important: Before installing the piston pin to the piston, set the J 24086-9 (part of the J 24086-C Kit) to the F2 setting for proper piston pin installation.

1.2. | Use the J 24086-C in order to press the piston pin into the piston and connecting rod assembly.

1.3. | Inspect for the proper installation of the piston and piston pin.

The piston should move freely on the piston pin with no binding or interference.

Notice: Use a piston ring expander to install the piston rings. The rings may be damaged if expanded more than necessary.

2. Install the piston rings onto the piston.

2.1. | Install the oil control piston ring spacer.

2.2. | Install the lower oil control piston ring.

2.3. | Install the upper oil control piston ring.

2.4. | Install the lower compression piston ring.

The mark on the side of the piston ring should face the top of the piston.

2.5. | Install the upper compression piston ring.

The mark on the side of the piston ring should face the top of the piston.

3. Space the compression piston ring end gaps 120 degrees apart.
4. Space the oil control piston ring end gaps a minimum of 90 degrees apart.
