Installation
NOTE: A Torx
®
tool is required for this procedure.
Cylinder head valve components MUST be aligned
in the proper position in order for the compressor
to function.
1. Install the sliding leafs. The two holes in each
sliding leaf must be installed over the two pins
on the base of the cylinder head.
Figure 3.4 .
NOTE: A light application of engine oil will
hold the sliding leaves to the inlet valves.
Figure 3.4 .
2. Lay the new cylinder head gasket in place,
ensuring that it fits over the guide bushings
and that the unloader hole allows air pressure
communication from the cylinder head to the
crankcase.
Figure 3.5 .
3. Place the inlet valves over the guide pins
provided, ensuring that the pads are up and
the valves will lie flat against the head
openings. A small amount of Lubriplate grease
can be used to ensure they remain in place for
the remainder of the assembly.
Figure 3.5 .
4. Position the cylinder head on top of the
compressor. Ensure the notched pins on the
cylinder head align with the recesses in the
block. Only four of the six bolt holes have
notched pins.
