(1) This tool is an alternative Valve Spring Compressor.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.
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.
Illustration 4 g00572757
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
Install Tooling (D) and install Tooling (B) without the hydraulic cylinder. Refer to Illustration 5. Move the handle downward to compress spring (4).
Illustration 6 g00572759
Do not remove or install the spring locks with your fingers. If the spring should move, personal injury may result.
Use a magnet to remove locks (2).
Illustration 7 g00572760
Release the pump pressure from Tooling (C). Remove compressor plate (3) from Tooling (B).
Illustration 8 g00614365
Remove rotocoil assemblies (5).
Illustration 9 g00614376
Remove outer valve springs (6)
