If the engine is to be used for core credit, refer to: * SELD0164 Core Acceptance CriteriaReference Literature
Refer to the Parts Manual for parts information for a specific Engine Arrangement.Each Remanufactured Engine arrangement has a Literature Group attached, which includes:* Parts Manual* Operation & Maintenance Manual* Lubrication Instructions* Torque Specifications (for fasteners) .. andSpecific Special Instructions that will provide, as close as possible, the most current engine/machine configuration.Refer to Special Instructions in this instruction.An attached envelope will contain:* Core Credit Request/Packing List .. and* Engine Delivery Service Record.Special Instructions
For maximum life and optimum performance, it is factory RECOMMENDED that the following specific Special Instructions be performed at installation.Each Special Instruction will be referenced by:* Form Number* Title* Model Designation* Effective Product Identification Number (PIN) .. and/or* Effective engine serial number or engine serial number rangeA brief review of the instruction is also included.SEHS9398 .. Installation of Multipoint Pressure Sensing System (MPPS)
793 3SJ1 - 12The Multipoint Pressure Sensing System Version of the SEHS9399 .. Automatic Ether Injection System (AEIS) provides a low oil pressure warning whose switch point varies with engine speed.The current low oil pressure warning on EMIS has only a single switch point which may not signal a loss of pressure at higher engine RPM until the oil level is very low.The (MPPS) measures engine RPM and oil pressure and compares it to a switch point curve of oil pressure vs RPM.It uses this to determine when a low oil pressure condition exists for any given RPM and signals it through the EMS Panel.This feature provides better protection of the engine in the event of a loss of oil pressure when running at or near rated speed.SEHS9340 .. Jacket Water Heater Installation Procedures
All Machine Models
The jacket water heater keeps the engine water temperature warm when ALL the ambient air temperature is below 13°C (55.4°F).The warm jacket aids in preventing rough combustion after cold start-ups.SEHS9241 .. Operator Instruction Card for Automatic Ether Injection (AEIS) Card
All Machine Models
This provides a new card to be installed in the machine cab.SEHS9227 .. Installation of Switches/Sensors with Sure-Seal Connectors
All Machine Models
This instruction provides the necessary procedure for field installation of upgraded electrical components where the original parts used screws, studs, blade, bullet or MS connectors instead of Sure-Seal connectors.Sure-Seal connectors offer improved reliability over the mentioned terminals.Installation of an upgraded component in place of the former component requires installation of a mating Sure-Seal connector on the machine harness.SEHS9632 .. Installation of 3516 Remanufactured (MUI) Engine for 793 Machines
793 3SJ1 - UpThis instruction contains adaptability and installation information.For improved service life and optimum performance of this Caterpillar Remanufactured engine, it is RECOMMENDED that this Special Instruction be performed at installation.Exchange of Parts
Each Remanufactured Engine is built to a reference engine arrangement, as shown in the Reference Literature Chart in this instruction.All 3500 series MUI Remanufactured Engines are remanufactured to the most critical engineering changes for the arrangement ordered:* Alternator belt guard* Camshaft* Connecting rods* Crankshaft* Exhaust manifold* Exhaust thermocouples* Fuel lines and clamps* Gear train* Governor* Lubrication tubes clamps* New exhaust valves,* New oil cooler cores* Oil pan* Pistons* Turbochargers* Valve lifters All non-metallic parts (gaskets, seals) and fasteners (bolts) are replaced and the improved parts are Remanufactured where applicable.This minimizes or eliminates the need for the user to make modifications and reduces downtime provided the CORRECT arrangement was ordered.However, some of the engine related engineering changes incorporated in the Remanufactured engine received may require machine changes at installation time to achieve optimum performance available from this updated Remanufactured Engine.The Special Instructions, as shown in the Reference Literature Chart, provides the effective Product Information Number of all the changes which may apply to the machine.If the machine's Product Information Number appears in the Reference Literature Chart it is RECOMMENDED that the update/changes be made to maximize the performance of this new Remanufactured Engine.Each Remanufactured Engine is built to the advertised Rated Power @ at specified RPM, that agrees with the original engine's power rating and rpm.This is recorded on each Remanufactured Engine Information Plate. Do NOT change/adjust any fuel setting(s) before referring to the specific Fuel Setting and Related Information Library.Inspect (Replace as Required), (Optional Parts Replacement), (Recommended Parts Replacement)
