3500 Engines and Short Blocks
Engine Configurations and "Updates"
Cat Remanufactured 3500 Engines may require modifications and additional parts for installation. To determine the correct Reman engine for each application, refer to the machine model and new engine arrangement number in the engine application chart on the following page. Caution: Some Reman engines are serviced at a slightly different level than their new engine counterparts. The new engine may not include a fan drive, for example, when the Reman engine does. If in doubt about the exact consist of a Reman engine, consult your dealership technical coordinator. Another source of information is the Reman "Hot Line" (in North America) on 1-888-88-REMAN.
Cat Remanufactured engines are remanufactured to the latest critical engineering changes. Customers will receive the most technically advanced engine available at time of engine remanufacture. Critical engineering changes incorporated into the Reman engine may require machine modifications at the time of engine installation. Search the latest service literature for the engine model being purchased (especially Service Magazine articles) and read any Installation Special Instructions shipped with the engine. Together, the service literature and Special Instructions will tell what engineering updates are included in the Reman engine and what modifications may need to be made to the machine before engine installation.
To look up replacement parts for a Remanufactured engine, refer to the new engine serial prefix and arrangement numbers. New parts are directly interchangeable unless the block has been bored or the crankshaft remachined undersized. The corresponding new engine arrangement number can be found on the Reman engine block identification plate. The engine block identification plate also includes the crankshaft rod and main journal sizes for each engine.
"Future Dated Orders" (FDO) vs. :Distribution" (Dist.) engines
Reman "Future Dated Orders" (FDO) 3500 engines will ship from the Caterpillar engine plant (Lafayette, Indiana) 90 days after the order is received by Caterpillar. Reman "Distribution" (Dist.) engines ship immediately from stock, using normal Cat parts distribution procedures.
Retrofitting newer engines to older machines
Reman is often used to update older machines in the field. When a Reman 3500 engine is used to update an older machine, the pricing logic is as follows: Dealers are charged the purchase price and core charge for the engine purchased. Dealers receive the core refund for the core returned. For example: MIU (Mechanical Unit Injection) engine cores are eligible for full MUI core deposit refund when purchasing a Reman EUI (Electronic Unit Injection) engine, subject to normal core acceptance criteria. The MUI core refund may be slightly less than the EUI core deposit. See the Core Acceptance Criteria for 3500 Engines (SELD0164) and EUI retrofit Special Instructions (777B-SEHS9690, 785-SEHS9688, 789- SEHS9674, and 793-SEHS9686) for detailed conversion information.
Former MAO Options
Effective January 1, 2004, the "Made As Ordered" (MAO) prgram was cancelled. It has been replaced with the "Future Dated Order" (FDO) program. The "MAO" program offered the ability to order engine arrangements in different paint stock colors, please note this option is no longer available in the new program. In addition, factory installed MAO attachments are no longer available. Service parts will need to be ordered through the normal distribution channels.
