DISASSEMBLY AND ASSEMBLY OF SUBASSEMBLIES

Cylinder Head

Disassembly

1. Remove the bracket.

2. Remove the rear lifting eye.

3. Remove the front lifting eye.

4. Remove the cylinder head temperature (ECT) sensor.

5. Using the SSTs, compress the valve spring and remove the valve spring retainer keys, the valve spring retainers, and the valve springs.

• Remove the SSTs.

6. Inspect the valve spring, valve spring retainer and valve spring retainer key. For additional information. (See VALVE, VALVE GUIDE INSPECTION.) Install new parts as necessary.

Note

• Mark each valve if the original valves are to be used.

7. Remove the valves.

8. Using the SSTs, remove and discard the valve stem seals.

9. Inspect the valves. For additional information. (See VALVE, VALVE GUIDE INSPECTION.) Install new parts as necessary.

Assembly

Note

• If installing the original valves, make sure the valves are installed in the position from which they were removed. Coat the valve stems with engine oil.

1. Install the valves.

Note

• Use the seal protector provided with the replacement kit to prevent damage to the valve stem seals.

2. Lubricate valve and guides with engine oil and using the SST install the valve stem seals onto the cylinder head valve guides.

3. Place the valve spring in position over the valve and install the valve spring retainer.

4. Using the SSTs, compress the valve spring and install the valve spring retainer keys.

• Remove the SSTs.

5. Install the ECT sensor.

6. Install the front lifting eye.

7. Install the rear lifting eye.

8. Install the bracket.

Piston - Pin Connecting Rod Assembly, Press Fit

Disassembly

1. Use the Piston Pin Tool to press the piston pin out from the piston assembly and connecting rod.

2. Remove the connecting rod and piston rings from the piston.

3. Clean and inspect the piston, piston pin and connecting rod. For additional information. (See PISTON, PISTON RING, PISTON PIN INSPECTION.)

Assembly

Caution

• PIP mark on pistons and squirt groove on connecting rods must be located on the intake side of engine or possible engine damage may occur.

• The arrow on the piston must point toward the front of the engine or engine damage may occur.

1. Lubricate the piston pin and piston pin bore.

2. Position the piston pin in the bore aligned with the connecting rod bore.

3. Use the Piston Pin Tool to press the piston pin into the piston and connecting rod assembly.

4. Fit and install the piston rings. For additional information. (See PISTON, PISTON RING, PISTON PIN INSPECTION.)
