Valves and valve stem seals — installation (Triumph Rocket III)

0

Removal from the cylinder head

1. Remove each valve from the head using a valve spring compressor. The compressor must act on the top cup to allow removal of the valve collets.

2. Once the collets are released, remove the following items:

• collets
• valve spring cap
• valve spring
• valve stem seal
• valve spring thrust washer

Installation

1. Apply a thin coat of molybdenum disulphide grease to the valve stem.

2. Install the valve into the valve guide and refit the thrust washer to the valve spring recess (if removed).

3. Fit the valve stem seal over the valve stem and, using a suitable tool, press down fully until the seal is correctly seated over the valve guide.

Note: During fitment of the valve stem seal, two distinctly different degrees of resistance will be noted when the seal is correctly fitted.

4. Firstly, press the seal down the valve stem until the lower side of the seal comes into contact with the valve guide. Greater resistance is felt at this contact point and further gentle pressure is then required to locate the seal over the top end of the valve guide.

5. On application of this pressure, the seal can be felt to positively locate over the top face of the valve guide. Once correctly positioned, the seal cannot be pushed down any further.

Caution! Incorrect fitment of the valve stem oil seals could lead to high oil consumption and blue smoke emissions from the exhaust system. Do not use excessive force in fitting the seal as this may break the seal ring.

6. Install the valve spring.

7. Compress the valve spring ensuring that the spring is compressed squarely to prevent damage to components.

8. Fit the valve collets ensuring their correct location in the spring cap and valve as the spring compressor is released.

Caution! Always check for correct location of the valve collets during and after assembly. If not fitted correctly, the collets may become dislodged when the engine is running allowing the valves to contact the pistons. Any such valve to piston contact will cause severe engine damage.
