John Deere 3029, 4039, 4045, 6059, 6068 — DYNAMIC TIMING (ALL PUMP TYPES)

Fuel System/Dynamic Timing DYNAMIC TIMING (ALL PUMP TYPES) Two types of dynamic timing are used: • Dynamic timing at full load rated speed when engine can be connected to a dynamometer (e.g. tractors). This method is more appropriate, as it corresponds more closely to the realistic use of the engine. • Dynamic timing at no-load when engine cannot be connected to dynamometer (e.g. combines). NOTE: Stroboscopic lamp (M) can be used for all engines while the magnetic probe can be used on recent engines (214170CD- ) only.
