Perkins 1104D (Mech) Industrial Engine Service Manual

The engine lubricating oil is supplied by a gear type pump. The engine lubricating oil is cooled and the engine lubricating oil is filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine parts when oil viscosity is high. Bypass valves can also provide unrestricted flow of lubrication oil to the engine parts if the oil cooler should become plugged or if the oil filter element should become plugged.

Engine efficiency, efficiency of emission controls, and engine performance depend on adherence to proper operation and maintenance recommendations. Engine performance and efficiency also depend on the use of recommended fuels, lubrication oils, and coolants. Refer to the Operation and Maintenance Manual, “Maintenance Interval Schedule” for more information on maintenance items.

Engine Cooling and Lubrication The cooling system consists of the following components:

  1. Gear-driven centrifugal water pump
  2. Water temperature regulator which regulates the engine coolant temperature
  3. Gear-driven oil pump (gear type)
  4. Oil cooler

Engine Service Life
Engine efficiency and maximum utilization of engine performance depend on the adherence to proper operation and maintenance recommendations. In addition, use recommended fuels, coolants, and lubricants. Use the Operation and Maintenance Manual as a guide for required engine maintenance.

Expected engine life is generally predicted by the average power that is demanded. The average power that is demanded is based on fuel consumption of the engine over a time period. Reduced hours of operation at full throttle and/or operating at reduced throttle settings result in a lower average power demand. Reduced hours of operation will increase the length of operating time before an engine overhaul is required.

Product Storage
Perkins are not responsible for damage which may occur when an engine is in storage after a period in service. Your Perkins dealer or your Perkins distributor can assist in preparing the engine for extended storage periods.
