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 and* Effective Product Identification Number (PIN) ... and/or* Effective engine serial number or engine serial number rangeA brief review of the instruction is also included.SEHS8880 ... Governor and Decelerator Control Linkage Modification
D11N ... 74Z1 - 372This instruction provides the procedure for modification of the 3T1049 Governor & Decelerator Control Group.The modification simplifies the linkage between the governor and the operators platform.The improved linkage eliminates the needle bearings at the control rod connections.The needle bearings were susceptible to dirt contamination, which caused the linkage to become difficult to operate.The improved linkage is not as susceptible to contamination and will improve service life.SEHS8895 ... Installation of Fumes Disposal Tube
D11N ... 74Z1 - 372A new fumes disposal tube plus additional parts are available from the Parts Department as replacement for the existing fumes disposal tube.Installation of the new group will allow the fumes to exit in front of the radiator core and help eliminate radiator core plugging resulting in HOT spots and possible overheating.SEHS8951 ... Installation of Engine Enclosure Group
D11N ... 74Z1 - UpIn some applications engine enclosures are needed to help keep debris (non-metallic material, rocks/dirt) out of the engine compartment.This debris can fill the engine compartment and shorten the engine vibration damper life and damage the engine oil pan.This instruction gives the procedure for field installation of the 6Y2396 Engine Enclosure Group.SEHS9173 ... Installation of Automatic Ether Injection System (AEIS)
D11N ... 74Z1 - 729The automatic ether injection system controls the amount of ether to be injected into the engine intake manifold during cold weather starting.Correct operation of this electrically controlled system is required to prevent possible damage to the engine during cold-start conditions.SEHS9186 ... Installing the 1W0723 Fan Guard Group
D11N ... 74Z1 - 846It is RECOMMENDED that Machines with Product Identification Number (PIN) 74Z1 - 846 be updated with the new 7E4931 and 7E4934 Guard Assemblies.SEHS9241 ... Operator Instruction Card for Automatic Ether Injection (AEIS) Card
All Machine ModelsThis provides a new card to be installed in the machine cab.SEHS9397 ... Installation of Multipoint Pressure Sensing System (MPPS) Version of Automatic Ether Injection System (AEIS)
D11N ... 74Z1 - 961The Multipoint Pressure Sensing System Version of the 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.SEHS9257 ... Installation of Overspeed Monitoring System
D11N ... 74Z1 - 828An engine overspeed warning system is now available for all D11N 74Z1 - 828 Tractors.The system will require the installation of an:* Engine speed pick up at the flywheel housing.* Electronic control mounted in the manhole (wiring harness from manhole to dash) ... and* A new cover at the top of the dash.SEHS9340 ... Jacket Water Heater Installation Procedures
All Machine ModelsThe 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.SEHS9227 ... Installation of Switches/Sensors with Sure-Seal Connectors
All Machine ModelsThis 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.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* Connecting rods* Crankshaft* Exhaust manifold* Exhaust thermocouples* Fuel lines and clamps* Gear train* Governor* Improved camshaft* Lubrication tubes and clamps* New exhaust valves* Oil pan* Oil cooler cores* Turbocharger* 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
