HYDRAULIC AR-LOWER 4415605 - Caterpillar

Introduction
It is both important and necessary for a short block or Remanufactured engine to have adequate (needed) lubrication during the first few seconds of its initial (first) start-up. A start-up without this needed lubrication can cause bearing damage.It is our recommendation to ALWAYS DO THE PRESSURE LUBRICATION PROCEDURE as given in this publication, BEFORE the initial start-up of a reconditioned or rebuilt enginePressure Lubrication Procedure
Some type of oil reservoir with a pressure gauge is needed to do the pressure lubrication procedure. In the procedure that follows, a tank assembly from a 1P0540 Flow Checking Tool Group is used for the oil reservoir. If one of these tanks is used in the pressure lubrication procedure, the inside of the tank must be thoroughly cleaned.
NEVER use the same tank assembly for both, the pressure lubrication procedure and the fuel flow checking procedure. It is not possible to get the tank assembly clean enough to do both operations. ANY AMOUNT OF DIRT, DEBRIS, ETC. CAN CAUSE FUEL NOZZLE FAILURE, if the tank is used for fuel flow checking after it has been used for the pressure lubrication procedure.Other sources of clean oil under pressure, such as a service shop central oil supply, can also be used for pressure lubrication.
1. Refer to the Operation and Maintenance Guide for the engine that is to have the pressure lubrication. Find the amount of oil needed to fill
