Introduction
This Special Instruction provides detailed instructions on the installation of the sleeve into the compensator group of the 3408E and 3412E Unit Injector Hydraulic Pump. If leaks are experienced at the joint of the compensator and the adapter block, the 174-8943 Sleeve may be installed to improve sealing. The new press fit sleeve contains the O-ring more securely than the original slip fit sleeve.Note: Engines built prior to the serial number break that contain the new sleeve have a "S" stamped at the end of the part number on the serial number plate of the pump. The reworked part numbers appear as "144-0835-06S". Individual Components

Invert the compensator assembly (1). Hold the compensator assembly securely within a vise or a press table.
Start the sleeve (2) by hand into the compensator assembly (1) .Note: It is important that the groove on the outside diameter of the sleeve is oriented toward the O-ring in the joint. If this is not done, there will not be sufficient room to properly seal the O-ring.
Press the sleeve (2) flush with the surface of the compensator assembly (1) using the 1P-0467 Drive Plate or by using an acceptable bearing insertion tool.Installation Of The O-Ring Seals
