Description
Perkins 400C Testing and Adjusting Manual covering the 402C-05, 403C-07, 403C-11, 403C-15, 403C-17, 404C-15, 404C-22 and turbocharged 404C-22T industrial diesel engines.
This factory technical publication combines systems operation information with practical testing and adjustment procedures. It is intended for diesel technicians, engine rebuilders and machinery workshops diagnosing or servicing the listed mechanically governed Perkins 400C engines.
The manual explains engine design and operating principles before providing inspection, testing and adjustment instructions. Subjects include the fuel, induction, exhaust, lubrication, cooling and electrical systems, together with checks for important internal engine components.
ENGINE DESIGN AND SYSTEMS OPERATION
The systems operation section provides technical descriptions and model-specific engine design information. Confirmed subjects include:
- Engine layout and cylinder arrangement
- Cylinder and valve locations
- Combustion type and compression ratio
- Valve lash and firing order
- Crankshaft and camshaft rotation
- Cylinder head, piston and bearing arrangements
- Timing gear operation and alignment
- Engine lubrication and coolant circulation
FUEL SYSTEM
The publication covers the mechanically actuated fuel injection system used by these engines. Workshop checks and adjustments include:
- Fuel system inspection
- Finding top-centre position for No. 1 piston
- Fuel injection timing checks
- Fuel injector testing
- Fuel quality testing
- Fuel system priming
- Front gear group timing
- Fuel shut-off solenoid testing
AIR INLET AND EXHAUST SYSTEM
Diagnostic information is provided for assessing engine breathing, combustion condition and related mechanical components:
- Air inlet and exhaust system inspection
- Wastegate testing where applicable
- Engine compression testing
- Valve lash inspection
- Valve depth inspection
- Valve guide inspection
LUBRICATION AND COOLING SYSTEMS
The Perkins 400C Testing and Adjusting Manual includes checks used to investigate oil-pressure, oil-consumption and cooling-system faults:
