Description
Air compressor pump service kit includes the 38-stroke connecting rod / eccentric bearing assembly, head gasket, diaphragm, filter, valve flappers, valve keepers, o-ring, and screws. Kit is compatible with standard Thomas 405AA38, 405AD38 models.
If you have a sudden loss of performance, if air leaks out of the intake filter, or if the compressor just isn't performing like it should, order this kit. A loss of pressure or slow pressurization is usually caused by either damaged compression rings, gaskets, and/or damaged or sticking valves.
Remember to tighten the bolts down to the proper torque specs as noted by the manufacturer.
