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 gaskets
securely so they do not separate.
Align each bolt hole in the valve bodies with the
gaskets 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
