REPAIR
a. Clean parts, using steam or solvent.
b. If sleeve bushing were removed, check sleeve bushings-(12) and sleeve bushng bores in manifolds (1,
i
9, and 10) for wear or damage. The outside diameter of the sleeve bushing (12) must be between
0.010 inch (0.25mm) and 0.070 inch (1.78mm) larger than the inside diameter of the bore into which it
is installed.
c. Inspect manifolds (1, 9, and 10) for cracks, distortion or evidence of leaking.
WARNING
High pressure compressed air tanks, piping systems, and
air operated devices possess potential for serious injury to
eyes and exposed areas of skin due to escaping air
pressure.
d. Plug manifold ports and apply compressed air at 20 psi (138 kPa).
e. Check for leaks. Replace manifold if leak is found in exhaust passage.
f. Inspect drain cocks (2) for signs of leakage, corrosion and damaged threads. Replace, if defective.
g. Inspect capscrews (3 and 8) for damaged threads, rounded heads and excessive corrosion.
h. Inspect water transfer connections (6) for cracks, corrosion and obvious damage. Replace, if defective.
ASSEMBLY
a. Install drain cocks (2) to manifolds (1, 9, and 10)
b. Coat the outside of the sleeve bushing (12) with antiseize compound.
CAUTION
Do not strike the sleeve bushing face with any tool,
including the soft-head mallet, or misalignment and exhaust
leaks may occur.
c. Using a wood block to the face of sleeve bushing (12), drive sleeve bushing (12) into the manifolds (1,
9, and 10) bore by gently striking the wood block with a soft-head mallet.
d. Position gaskets (11) on each manifold end, with bolt holes aligned and sleevebushing (12) through
center hole of gasket (11).
