Bendix 107516N is a Genuine Bendix OEM cylinder-head field maintenance kit for Tu-Flo 550 and Tu-Flo 750 air compressors used on heavy-duty truck air-brake systems. The kit rebuilds the compressor head: it includes the inlet and discharge valves, valve seats, springs, unloader pistons, head gasket, governor-mount gasket, and supporting o-rings — everything required to restore compressor breathing without removing the compressor block from the engine.
