New Exhaust Pipe Connector Makes A Tighter Seal Between Pipe And Manifold

Usage:




3208 Industrial And Truck Engines

Description of Change: A new connector assembly is used to fasten the exhaust pipe to the exhaust manifold on the above models. The new connector has an improved shape in the area that fits against the exhaust manifold. The improved shape gives a tighter seal to prevent possible leakage of exhaust gas.

Adaptable As: Direct replacement. The new 8N4709 Connector Assembly can be used in place of the former 9L7132 Connector Assembly on all earlier models. Two are used, one at each side of the engine. The former connector assembly is canceled and, if ordered, the new part will be sent.
