Remanufactured Engine References
Distribution engines are built to the OR-3980 engine arrangement. Made as ordered engines are built to the OR-3990 engine arrangement. Both of the remanufactured 3508 EUI engine arrangements for D11N Tractors (4HK) are built to the following references.* Reference Engine Arrangement ... 7E-9077* Reference Engine S/N ... 7YG1-UpEach remanufactured engine arrangement has a literature group attached, which includes:* Parts Manual* Operation & Maintenance* Lubrication Instructions* Torque Specifications (for fasteners)* Other specific Special Instructions that will provide references, as close as possible, to the most current engine/machine configuration.An attached envelope will contain:* Core Credit Request/Packing List* Engine Delivery Service RecordAll 3500 EUI remanufactured engines are remanufactured to include the most critical engineering changes for the arrangement ordered. A list of typical critical items follows.* Camshaft* Crankshaft* Cylinder Packs* Exhaust manifolds* Exhaust thermocouples* Exhaust valves* Fuel lines and clamps* Gear train* Governor* Lubrication tubes and clamps* Oil cooler cores* Turbochargers* Valve lifters All non-metallic parts (gaskets, seals) and fasteners (bolts) are replaced and updated parts are included where applicable.This minimizes or eliminates the need for the user to make modifications and reduces downtime provided the CORRECT arrangement was orderedSome of the engine related engineering changes incorporated in the remanufactured engine received may require machine changes at time of installation to achieve expected performance available from this updated remanufactured engine.Each remanufactured engine is built to a specific power rating at a specific rpm, that agrees with the original engine's power rating and rpm.This information is recorded on each remanufactured engine's Information Plate. Do NOT change/adjust any fuel setting(s) before referring to the specific specification found in the Fuel Setting and Related Information records.Reference Literature
