1. POSITION NO. 1 PLATE AND NEW GASKETS ON
UPPER VALVE BODY
Position new No. 1 gasket, No. 1 plate and then new No. 2
gasket on the upper valve body.
HINT: Since No. 1 gasket and No. 2 gasket are similar,
use the illustration below to discriminate between them.
2. PLACE UPPER VALVE BODY WITH NO. 1 PLATE AND
GASKETS ON LOWER VALVE BODY
Hold the upper valve body, No. 1 plate and gasket;
securely so they do not separate.
Align each bolt hole in the valve bodies with the gasket;
and plate.
3. INSTALL AND FINGER TIGHTEN BOLTS IN UPPER
VALVE BODY TO SECURE LOWER VALVE BODY
Install and finger tighten the three bolts.
HINT: Each bolt length (mm (in.)) is indicated in the
figure.
