ENGINE STORAGE ENGINE STORAGE When an engine is to be stored or removed from operation for a period of time, special precautions should be taken to protect the interior and exterior of the engine, transmission and other parts from rust accumulation and corrosion. The parts requiring attention and the recommended preparations are given below. 1. With the engine at ambient temperature and cool to the touch, drain engine crankcase oil into a suitable container. Dispose of the oil in an environmentally friendly manner, according to state and/or federal EPA recommendations. 2. Fill the crankcase to the proper level with the recommended viscosity and grade of oil. Preparing Engine for Storage 3.
Fill the fuel tank with the recommended grade of fuel oil. Operate the engine for two (2) minutes at 1200 rpm and no load. Do not drain the fuel system or the crankcase after this run. It will be necessary to remove all rust or corrosion completely from any exposed part before applying rust preventive compound. Therefore, it is recommended that the engine be processed for storage as soon as possible after removal from operation. 4. Check the air cleaner and service it, if necessary. The engine should be stored in a building that is dry and can be heated during the winter months.
Moisture-absorbing chemicals are available commercially for use when excessive dampness prevails in the storage area. 5. If freezing weather is expected during the storage period, check the antifreeze/coolant for required freeze and inhibitor protection. Add antifreeze solution to the cooling system in accordance with Detroit Diesels recommendations. Refer to the How to Select Coolant in this guide. Temporary Storage (30 Days or Less) To protect the engine for a temporary period of time (30 days or less), follow this procedure: NOTE:
If an antifreeze solution is not required during storage, flush the cooling system with a good soluble oil (3% 5% by volume) rust inhibitor to prevent 132 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION
