TURBOCHARGER GP 10R1012 - Caterpillar

All Earthmoving MachinesIntroduction
The purpose of this instruction is to aid in the proper use of the 4C3502 Engine Repair Indicator Kit designed for dealer Product Support Sales Representatives (PSSR).The kit enables a few simple tests to be made which will assist the PSSR in evaluating a machine's condition and in many cases determine if a before failure overhaul is recommended for the engine. When a determination cannot be made from the following procedure the dealers Service Department should be consulted for further machine evaluation.The tests described in this instruction are not intended to be a substitute for any type of inspection which might be performed by a qualified Caterpillar service mechanic.Before making a call on a customer, inspect each item in the kit to ensure it is included and in good working order. The test should be first performed on a machine in the dealership to become more familiar with the tooling.
PEEP8211 Engine Evaluation WorksheetThe Engine Evaluation Worksheet, form PEEP8211, included with the kit should be used to record the data obtained from the test. The worksheet aids in the completion of the machine condition evaluation and determination for a before failure overhaul.This instruction covers each separate section of the evaluation worksheet and the use of tooling, tests and procedures for each section.Necessary Parts
The following chart lists the items in each 4C3502 Engine Repair Indicator Kit. Replacement parts/forms can be ordered from the Parts Department except for the items with alternate sources indicated.
The kit contains only a sampling of Lubrication and Maintenance Interval Decals. A complete listing of available decals is published quarterly in the Service Magazine.
Customer And Machine Information
It is essential that this section of the worksheet be completed in full for proper documentation of the inspection. This information will allow you to begin a history file, by machine, that may be referenced later. It also contains key information to assist your Service Department should they be required to further inspect the machine or conduct repairs.Machine Working Conditions
The questions in this section are related to the machine application and its operating environment. These questions are required for the Engine Overhaul Estimator Guide calculations.The question regarding load factor assigns a rating to the amount of time the engine is fully loaded and therefore burning a maximum amount of fuel. The following descriptions will assist in rating the particular machine application being evaluated.
The load factor descriptions may also be found in the Performance Handbook and on the Overhaul Estimator.
Track-Type Tractors
High: Steady ripping, shuttle pushloading, agricultural drawbar work at full throttle, little or no idle or travel in reverse. Medium: Production dozing, pulling scrapers, most pushloading. Low: Considerable idle or travel with no load.Motor Graders
High: Ditching, fill spreading, spreading base material, ripping, heavy road maintenance, snow plowing. Medium: Average road maintenance, road mix work, scarifying, snow plowing. Low: Finish grading, light maintenance, road travel.Skidders
High: Skidding large loads [6810 kg (15000 lb) for the 518; 11350 kg (25000 lb) for the 528] in steep terrain (over 10%) with high skidding resistance.
