Caterpillar G3600 A4 Systems Operation & Testing Manual

This 116-page Caterpillar publication covers systems operation plus testing and adjusting information for G3600 A4 Engines. Publication KENR9773-05, dated February 2019, provides detailed information on engine control, ignition, gaseous fuel, air handling, lubrication, cooling, basic engine components, starting and electrical systems, followed by practical testing and adjustment procedures.

Engines & Applicability Covered

The manual contains specific information for the following G3600-series A4 engines:

• G3606
• G3608
• G3612
• G3616

The cover identifies the engine serial-number ranges ZZY 1-UP (Engine), JFE 1-UP (Engine), BB2 1-UP (Engine) and XH7 1-UP (Engine).

Main Systems & Subjects Included

• Electronic Control System operation and parameters
• Engine monitoring and protection system
• Electronic Control Module (ECM), Integrated Sensing Module (ISM) and Cat Electronic Technician (ET) functions
• Engine governing, speed control and timing control
• Ignition transformers, spark plugs and detonation monitoring
• Air/fuel ratio control and gaseous fuel parameters
• Fuel metering valve, gas shutoff valve and precombustion chamber operation
• Air inlet and exhaust system components
• Aftercooler, air inlet choke, exhaust manifold and turbocharger
• Exhaust bypass valve (wastegate)
• Lubrication system and engine oil flow
• Cooling system, jacket water system, aftercooler and oil cooler system
• Cylinder block, liners and cylinder heads
• Pistons, rings, connecting rods, crankshaft and camshaft
• Manual barring group and valve mechanism
• Air starting system
• Electrical system, grounding, alternator and circuit breaker

Testing, Adjusting & Service Coverage

The testing and adjusting section supports a wide range of inspection, measurement and adjustment work on these engines, including:

• Engine governing and engine speed sensor adjustment
• Hydraulic oil pressure adjustment for electrohydraulic actuators
• Ignition transformer checks and spark plug service information
• Gas pressure testing and adjustment of pressure to the fuel metering valve
• Finding the Top Center position for the No. 1 piston
• Camshaft timing checks and adjustment
• BTU and precombustion chamber adjustments
• Fuel-quality setting, misfire detection and G3600 tuning procedures
• Air inlet and exhaust restriction checks
• Crankshaft positioning for valve lash setting
• Valve lash, valve bridge and gas admission valve lash procedures
• Engine oil pressure measurement and inspection of excessive oil consumption or bearing wear
• Cooling system visual inspection, pressure-cap testing and coolant temperature sensor testing
• Water temperature regulator testing
• Connecting rod and main bearing inspection
• Crankshaft deflection checks
• Flywheel and flywheel housing inspection and runout measurement
• Vibration damper checks and engine alignment inspection
• Air starting pressure regulator, lubricator and strainer procedures
• Charging system, alternator regulator and battery testing

The manual includes detailed system explanations, diagrams, tables, required-tool information and measured values. For example, the fuel-system section specifies fuel supply pressure and regulated fuel pressure and provides the procedure for checking and adjusting pressure at the fuel metering valve.

Why This Manual Is Useful

This publication combines an explanation of how the G3600 A4 engine systems operate with the procedures needed to test and adjust those systems. That makes it particularly useful when diagnosing operating conditions, checking engine settings, performing timing or valve adjustments, inspecting mechanical components, or working with the electronic control and gaseous-fuel systems.
