This manual covers the overhaul, repair and maintenance procedures for Thermo King di and se 2.2 diesel engines. Design changes and improvements have been made to the di and se 2.2 engines over the years in a continuing effort by Thermo King to provide the latest in diesel engine technol- ogy. Before beginning any service to your engine, please review the engine chart on page 108 to determine which version di or se 2.2 engine you have. Doing so will help assist the mechanic with determining special service procedures and interchangeability of components between the various engines. Although the di 2.2 and se 2.2 engines are different ver- sions of the same engine, the following components are not interchangeable: Injection pump, gear case cover, gear case backing plate, oil base, transfer pump, flywheel housing, intake and exhaust manifolds, oil filter and housing, crankcase breather, water pump, thermostat housing and timing gears. Refer to the Parts Interchange Section located in the rear of the manual. APA06 Thermo King di 2.2 Diesel Engine All Thermo King 2.2 diesel engines are four cylinder, four stroke, water cooled engines that use a direct injection fuel system. The engines are configured so that all maintenance can be performed from one side of the engine. This heavy duty engine is designed with five main bearings on the crankshaft. Its rugged construction, when combined with a routine preventive maintenance program, will provide many hours of satisfactory service. Eventually, even the best designed engines require an overhaul. This manual provides the proper procedures to restore the engine to a rebuilt condition. A properly rebuilt engine will provide thousands of further hours of satisfactory service. The specifications section lists the sizes and tolerances used in the original assembly of the engine. All tables for oversize and wear limits for particular components are found in the sections dealing with these specific components.
