A 442-7299 Valve Spring Compressor 1 Start By:
Remove the cylinder head. Refer to Disassembly and Assembly, "Cylinder Head - Remove".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Clean the bottom face of the cylinder head. Check the depth of the valves below the face of the cylinder head before the valve springs are removed. Refer to Specifications, "Cylinder Head Valves" for the correct dimensions.
Place a temporary identification mark on the heads of the valves in order to identify the correct position. Inlet valves have a recess in the center of the head. Note: Do not stamp the heads of the valve. Stamping or punching the heads of the valves could cause the valves to fracture.
Use a suitable lifting device to position the cylinder head with the valve springs upward. The weight of the cylinder head is approximately 56 kg (125 lb). Note: Ensure that the cylinder head is kept on a clean, soft surface in order to prevent damage to the machined face.
Personal injury can result from being struck by parts propelled by a released spring force.Make sure to wear all necessary protective equipment.Follow the recommended procedure and use all recommended tooling to release the spring force.

Typical example
Illustration 2 g03820420
Typical example
Install Tooling (A) in position on the cylinder head in order to compress the appropriate valve spring.
Ensure that the valve spring is compressed squarely or damage to the valve stem may occur.
Apply sufficient pressure to Tooling (A) in order to remove valve keepers (1). Note: Do not compress the spring so that valve spring retainer (2) touches valve stem seal (4).
Slowly release the pressure on Tooling (A).
Remove valve spring retainer (2). Remove valve spring (3).
Repeat Steps 4 to 7 for the remaining valves.
Remove Tooling (A).
Remove valve stem seals (4).
Use a suitable lifting device to carefully turn over the cylinder head.
Remove valves (5). Installation Procedure

Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Clean all components of the cylinder head assembly. Ensure that all ports, all coolant passages, and all lubrication passages in the cylinder head are free from debris. Follow Steps 1.a through 1.e in order to inspect the components of the cylinder head assembly. Replace any components that are worn or damaged.
Inspect the cylinder head for wear and for damage. Refer to Systems Operation, Testing and Adjusting, "Cylinder Head Inspect".
Inspect the valve seats for wear and for damage. Refer to Specifications, "Cylinder Head Valves" for further information.
Inspect the valve guides for wear and for damage. Refer to Specifications, "Cylinder Head Valves" and Systems Operation, Testing and Adjusting, "Valve Guide - Inspect" for further information.
Inspect the valves for wear and for damage. Refer to Specifications, "Cylinder Head Valves".
Inspect the valve springs for the correct length. Refer to Specifications, "Cylinder Head Valves".

Lubricate the stems of valves (6) with clean engine oil. Install valves (5) in the appropriate positions in the cylinder head. Check the depth of the valves below the face of the cylinder head. Refer to Systems Operation, Testing and Adjusting, "Valve Depth - Inspect" for more information.
Use a suitable lifting device to carefully turn over the cylinder head. The weight of the cylinder head is approximately 56 kg (125 lb). Note: Ensure that all of the valves remain in place.
Use Tooling (B) in order to install new valve stem seals (4) onto each of the valve guides. Note: The outer face of the valve guides must be clean and dry before installing the valve stem seals.
Install valve spring (3) onto the cylinder head. Position valve spring retainer (2) onto valve spring (3).
Personal injury can result from being struck by parts propelled by a released spring force.Make sure to wear all necessary protective equipment.Follow the recommended procedure and use all recommended tooling to release the spring force.
