Valve Seal/Spring Service (On Engine)
NOTE: The following procedure is only for servicing
the top end of the valve train when replacing valve
springs or replacing valve seals.
In some cases the valve train can be serviced while the
cylinder head is still on the engine. Keep all parts in order
with respect to their location in the cylinder head.
WARNING
Wear eye protection or a face shield during cylinder
head disassembly and reassembly.
1. Having already removed the valve cover, rocker
arms and pushrods, align the cylinder to be worked
on at top dead center (TDC). Install the Valve
Pressure Hose (PU-45652) into the spark plug hole.
Hook the hose to an air compressor and supply 50 to
100 psi to the hose. This will seat the valves during
valve spring removal. Do not remove air from the
hose at anytime until reassembly is completed.
2. Using the Valve Spring Compressor (PU-45257),
compress the valve spring and remove the valve
keepers. NOTE: A small parts magnet (A) can aid in
the removal of the retainers (B).
IMPORTANT: To prevent damage to the valve
seals, do not compress the valve spring more
than is needed to remove the valve keepers.
3. Remove spring retainer and spring.
4. The valve seals are now serviceable.
Cylinder Head Disassembly
1. Carefully remove the cylinder components. Place the
hydraulic lifters (C), pushrods (D), and rocker arms
(E) in a safe, clean area.
