A 9U-6195 Valve Spring Compressor 1 Start By:
Remove the cylinder head assembly. 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. Use a dial indicator to check the depth of the valves below the face of the cylinder head before the valve springs are removed. Refer to Specifications, RENR2401, "Cylinder Head Valves" for the correct dimensions.
Place an index mark on the heads of the inlet valves and the exhaust valves for installation purposes.
Illustration 1 g00545731
Use Tooling (A) to compress inner springs (3) and outer springs (4). Note: Some engines may have only a single inlet valve spring and a single exhaust valve spring.
Remove valve keepers (1).
The valve keepers can be thrown from the valve when the valve spring compressor is released. Ensure that the valve keepers are properly installed on the valve stem. To help prevent personal injury, keep away from the front of the valve keepers and valve springs during the installation of the valves.
Slowly release the pressure on Tooling (A) and remove Tooling (A).
Remove valve spring retainers (2).
Remove inner springs (3) and outer springs (4).
Remove seals (5).
Remove valve spring seat washers (6).
Remove inlet valves (7) and exhaust valves (7). Installation Procedure

Lubricate the stems of inlet valves (7) and the stems of exhaust valves (7) with clean engine oil.
Install inlet valves (7) and exhaust valves (7) in the respective positions.
Install valve spring seat washers (6).
Install new seals (5).
Install inner springs (3) and outer springs (4). Note: Install inner springs (3) and outer springs (4) on the valve spring seat washers with the damper coils toward the cylinder head. This is done with double valve springs. If single valve springs are used, the springs can be installed in either way.
Install valve spring retainers (2).
The valve keepers can be thrown from the valve when the valve spring compressor is released. Ensure that the valve keepers are properly installed on the valve stem. To help prevent personal injury, keep away from the front of the valve keepers and valve springs during the installation of the valves.
Use Tooling (A) to compress inner springs (3) and outer springs (4). Note: Some engines may have only a single inlet valve spring and a single exhaust valve spring.
Install valve keepers (1).
Slowly release the pressure on Tooling (A) and remove Tooling (A). Strike the top of the valves with a soft hammer in order to ensure that the valve keepers are properly installed. Note: Refer to Specifications, RENR2401, "Cylinder Head Valves" for more information on inlet valves and exhaust valves.
Use a dial indicator to check the depth of the new valves below the cylinder head. If the depth of the new valves is below the correct depth, the
