Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Note: Turn adjustment screw (1) by hand. Do not use wrenches.
Remove the cap that covers adjustment screw (1) and loosen locknut (2).
Hand tighten adjustment screw (1) clockwise into the lubrication injector which will push stem (3) downward into the body of the lubrication injector. Continue turning until the adjustment screw has bottomed out.
Turn adjustment screw (1) counterclockwise to the specified number of turns. This action sets the injector for the desired amount of grease to be displaced. Refer to Testing and Adjusting, "Lubrication Injector Banks - Adjust" for the specified setting of adjustment screw (1). Note: The 5T-5045 Lubrication Injector (SL-1) and the 307-3245 Lubrication Injector (SL-V) actuate differently. When you back off adjustment screw (1) on the SL-1 injector, stem (3) will follow the adjustment screw. When you back off adjustment screw (1) on the SL-V injector, stem (3) may remain in the float position.
Tighten locknut (2) and replace the cap.
