SUCTION MANIFOLD ASSEMBLY REPAIR.
This task covers:
a. Inspect
b. Disassembly
c. Repair
d. Assembly
INITIAL SETUP
Tools
Equipment Condition
General Mechanics Tool Kit (App B, Sect III, Item 1)
Suction Manifold removed (Para 3-19)
Calipers (App B, Sect III, Item 3)
Materials/Parts
Wear Ring (App F, Item 39)
NOTE
Repair of the 600 GPM suction manifold is shown, repair of 200 GPM suction
manifold is similar.
a. INSPECT. Refer to Figure 4-1.
(1)
Inspect the bronze wear ring (1) in suction manifold (2) for wear. If wear is noticeable, use formula A - B = C to
determine wear on the bronze wear ring (1).
(a)
Measure the inside diameter of the bronze wear ring (1) to determine dimension A.
(b)
Measure the outside diameter of the impeller wear ring (3) to determine dimension B.
(c)
Subtract dimension B from dimension A.
(d)
Dimension C is the difference between dimension A and B
NOTES
If the difference between dimensions A and B on the 200 GPM suction manifold
P/N 43865 exceeds 0.024 inch, replace the bronze wear ring.
If the difference between dimensions A and B on the 600 GPM exceeds 0.026
inch, replace the bronze wear ring.
(2)
Inspect suction manifold (2) for cracks, corrosion and worn or damaged seats.
b. DISASSEMBLY.
(1)
Remove setscrews (4) from suction manifold (2).
