Proven Results

COOPER CASE STUDY: Great job by our Northeast Region Cooper shop team in manufacturing this new custom-designed air intake manifold for a Clark TCVC-20 (12,000 HP) located in Mississippi. Cooper engineers designed this two-piece manifold to replace a cracked one-piece bank manifold. The new manifold is a drop-in replacement of the original, and the two 20’ sections are much easier to handle and install than the one piece. The Cooper service team will install the manifold during an upcoming overhaul.
