(1) This tool is an alternative Valve Spring Compressor ToolStart By:
Remove the cylinder head. Refer to Disassembly and Assembly, "Cylinder Head - Remove".Note: Use 8T-0447 Dial Calipers to measure the dimensions in the following procedure.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Refer to Disassembly and Assembly, "General Information (Reference Material)" for more information.
Put the cylinder head assembly in position on Tooling (A). Put the cylinder head assembly in position so that the valve seat faces upward.
Illustration 1 g00614352Note: Use the hydraulic cylinder only in the position that is shown in Illustration 1.
Illustration 2 g00614355
Install Tooling (B) in the position that is shown in Illustration 2. The threaded end of the bolt must face downward.
Illustration 3 g00572756
Turn the cylinder head to a position of 90° on Tooling (A). Install plate (1) and the nut. Plate (1) can be fabricated from 35.5 mm (1.40 inch) flat stock. The plate must measure 32.0 mm (1.25 inch) by 133.0 mm (5.25 inch) with a 16.5 mm (0.65 inch) hole at the center. The plate will hold the valves when the valve stems are turned upward.

Personal injury can result from parts and/or covers under spring pressure.Spring force will be released when covers are removed.Be prepared to hold spring loaded covers as the bolts are loosened.
Install compressor plate (3). This plate is part of Tooling (B). Install the nut and the washer.Note: Loosen the nut that holds plate (1) to allow the bolt to move. The nut is a part of Tooling (B).
Loosen the nut that holds plate (1) to allow the bolt to move enough to compress springs (4). This action also allows you to remove locks (2). The nut is a part of Tooling (B).
Compress the springs with Tooling (C) and remove locks (2).Note: The following two steps show an alternate method of compressing the valve springs.
Illustration 5 g00614360
Personal injury can result from parts and/or covers under spring pressure.Spring force will be released when covers are removed.Be prepared to hold spring loaded covers as the bolts are loosened.
Install Tooling (D) and install Tooling (B) without the hydraulic cylinder. Refer to Illustration 5. Move the handle
