Cylinder Head

Cylinder Head





Material

Disassembly
1. Remove the lifting bracket from the cylinder head.
2. Prior to removing the exhaust manifold, inspect the exhaust manifold for warpage with a feeler gauge between the manifold and cylinder head. Record the measurement and compare with the specifications.





3. NOTE: LH exhaust manifold shown, RH similar.

Remove the bolts and the exhaust manifolds.





4. Remove the bolts and separate the rocker arm carrier from the cylinder head.





5. Remove the press-in-place gasket.
^ Clean and inspect the gasket. Install a new gasket if necessary.
^ Remove the cylinder head dowels.
^ Clean and inspect the sealing surfaces.








6. Install the valve spring compressor.





7. NOTE: If necessary, strike the valve stem end with a plastic-tipped hammer to loosen the valve spring retainer keys.

Remove the valve spring retainer keys.
1 Remove the valve spring retainer keys.
2 Remove the valve spring compressor.





8. Remove the valve spring rotator.





9. Remove the valve spring.





10. Remove the valve.





11. Remove the valve stem seal.
12. Clean and inspect the valves, valve guides and seats. If they are serviceable, resurface to specification.

Assembly





1. Install the valve stem seal.





2. Install the valve.





3. Install the valve spring.





4. Install the valve spring rotator.





5. Install the valve spring retainer keys.
1 Install the valve spring compressor.
2 Install the valve spring retainer keys.





6. Remove the valve spring compressor.





7. Install the press-in-place gasket.
^ Install new dowels in the cylinder head, and install the gasket.





8. Install the rocker arm carrier on the cylinder head and install the bolts.





9. NOTE: When installing the exhaust manifolds, only use prevailing torque hex flange bolts with an interference fit.

NOTE: Start installing the bolts with the second bolt from the rear on the top. The hole diameter is smaller, therefore allowing alignment of the retaining bolts.

NOTE: Apply anti-seize lubricant to the bolt threads prior to installing the bolts.

Install the LH manifold and bolts. Tighten in the sequence shown.
