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.
• 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.
• 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.
