Improvements Made To Remanufactured 0R-3008 Fuel Transfer Pump{1256}

Usage:

3406B And 3406C Truck Engines

Several improvements have been made to the Remanufactured 0R-3008 Fuel Transfer Pump available for use on these truck engines. The improvements include:

* The use of pump "MASTERS" to insure correlation between the test machines at the remanufacturing plant and the original equipment manufacturer. This assures test accuracy and repeatability.

* The use of an air/electronic gauge to insure proper clearance between the tappet plunger and the tappet body. This helps prevent fuel dilution of the engine crankcase oil.

* The use of a spring tester to help insure quality of the transfer pump center spring and proper pump discharge pressures.
