CARTRIDGE 6E4266 - Caterpillar

Introduction
The following procedure is used in order to adjust the amount of lubricant that is supplied by the automatic lubrication system.Machine Preparation
ReferenceBefore you perform this adjustment, refer to Testing and Adjusting, "Machine Preparation for Troubleshooting".
Stop the machine on a hard level surface. Move the transmission control lever to the NEUTRAL position. Shut off the engine. Place blocks in front of the wheels and place blocks behind the wheels.
Engage the parking brake.Adjustment Procedure

(1) Stem (2) Adjustment screw (3) Locknut (4) Discharge chamber (5) PistonThe amount of lubricant that is supplied to the bearing is determined by the volume of discharge chamber (4) . This volume is controlled by adjustment screw (2) . Adjustment screw (2) controls the travel of piston (5) . When you turn adjustment screw (2) clockwise, the lubricant that is injected decreases. When you turn adjustment screw (2) counterclockwise, the lubricant that is injected increases.Note: One 360° turn of the adjustment screw is equal to approximately 0.23 cc (0.014 cubic inch) of lubricant. All injectors are factory preset half way or four turns from the assembly line.Movement of stem (1) indicates that the injector is working. When the injector discharges lubricant, stem (1) moves into the body of adjustment screw (2) . When the injector is filling with lubricant, stem (2) moves back out of the body of adjustment screw (1) until piston (5) rests against the stop.If an injector has been repaired or an injector has been replaced, proper adjustment of the measuring chamber is required. Proper adjustment of adjustment screw (2) and the measuring chamber will depend on the bearing that is being lubricated.Note: The lubrication system should be in the vented condition when the injectors are adjusted. Make sure that the lines are not pressurized when the injectors are adjusted.
Remove the cap that covers adjustment screw (2) and loosen locknut (3) .
Hand tighten adjustment screw (2) clockwise into the lubrication injector until it bottoms out. Turn adjustment screw (2) counterclockwise to the specified number of turns. To return to factory settings, turn adjustment screw (2) half way or four turns counterclockwise.
Tighten locknut (3) to 75 10 N m (55 7 lb ft) after the adjustment has been made. Replace the cap.
