SECTION 3
Assembly
Components must be clean and aII serviceable gaskets must be
replaced.
The reed valve of the 8 and 9.8 is unique and requires
special handling.
This reed valve is made of a thin 0.00787 in (0.2 mm)
stainless steel and can be damaged if mishandled.
When assembling the reed valve note that the two
7
surfaces of the valve are different. Align the notches
(1) as shown when assembling.
The reed valve screws (2) are coated with an adhesive.
When installing the reed valve, tighten new reed valve
screws to 6.1 - 7.8 in-lb [0.7 - 0.9 N·m, 0.07 - 0.09
kg-m]
NEVER reinstaII the used reed valve screws because
the effect of the adhesive has been lost and may lead
to reed valve failure during operation.
Verify that the clearance between the reed valve and
the valve seat is 0.0078 in (0.2 mm) or less after
assembly
