A 9U-6195 Valve Spring Compressor 1
B 268-1969 Adapter 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.
Illustration 1 g01430303
Typical example
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.
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.
Illustration 2 g01380536
Typical example
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.
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 -
