Air Compressor Pump Rebuild Kit for B4900A pump, includes complete gasket kit, ring set (for LP and HP pistons), oil seal, and conrod insert bearings.

Note: Does not include the valve plate assembly or the air filter.

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 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.
