(Assembly of Valve Body)
(See page AT±121)
1. POSITION PLATE AND NEW GASKETS ON LOWER
VALVE BODY
Position the new No. 2 gasket, the plate and then the new
No. 1 gasket on the lower valve body.
HINT: Since No. 1 gasket and No. 2 gasket are similar use
the illustration below to discriminate between them.
2. PLACE LOWER VALVE BODY WITH PLATE AND
GASKETS ON UPPER VALVE BODY
HINT: Hold the lower valve body, gaskets and plate
securely so they do not separate.
Align each bolt hole in the valve bodies with the gas-
kets and plate.
3. INSTALL AND FINGER TIGHTEN BOLTS IN LOWER
VALVE BODY TO SECURE UPPER VALVE BODY
