Introduction and General Safety Instructions

The opening section covers the symbols used throughout the manual, illustration conventions, and a full set of general safety instructions. This includes work environment requirements, personal protective equipment (eye, foot, head, face, hand, hearing, respiratory and fall protection), safe handling of diesel fuel, biodiesel, compressed natural gas, liquefied natural gas, liquefied petroleum gas, coolant, lubricating oil, refrigerant, solvents, starting aids, and hazardous substances including diesel engine exhaust, mercury and vanadium pentoxide. Electrical safety around batteries, high-temperature areas, heavy objects and pressurized systems is also covered, along with job safety assessment and ergonomic work practices.

Engine Identification

This chapter explains how to read the engine dataplate, fuel injection pump dataplate, engine control module (ECM) dataplate, air compressor dataplate, variable geometry turbocharger (VGT) dataplate and exhaust aftertreatment assembly stampings. It includes the Cummins engine nomenclature system and the Cummins Service Engine Model Identification procedure (100-005) and Product Technology procedure (100-006), which together describe the ISB6.7 CM2350 B103 engine’s electronic control system, air handling, fuel system and exhaust system features. The CM2350 control module with two 96-pin connectors and the Bosch common rail fuel system are detailed here.

Operating Instructions

This is the largest operational section. It covers the normal starting procedure, cold weather starting, starting after extended shutdown or oil change, jump starting with parallel and series battery connections, engine operating range, engine braking system with variable geometry turbocharger exhaust brake, engine shutdown procedure, and the electronically controlled fuel system. It also explains the unique operating characteristics of engines with aftertreatment diesel particulate filter, airless selective catalytic reduction (SCR), and on-board diagnostics. Engine indicator lamps — wait-to-start, check engine, malfunction indicator, stop engine, high exhaust system temperature, aftertreatment DPF, and diesel exhaust fluid lamps — are described in detail with what each illumination or flashing condition means and what action the operator should take. The electronic fuel system section covers ECM inputs, diagnostic fault codes, fault code flashout, throttle-activated diagnostic switch, engine protection system, fault code snapshot data, and the INSITE electronic service tool.

Maintenance Guidelines

The maintenance section provides the full maintenance schedule with intervals at daily, 12,000 km / 250 hours / 3 months, 24,000 km / 500 hours / 6 months, 48,000 km / 1000 hours / 1 year, 96,000 km / 2000 hours, 120,000 km / 2500 hours, 241,500 km / 5000 hours / 4 years, and 300,000 km / 6500 hours. It includes oil drain interval determination based on duty cycle and fuel consumption for municipal, tipper, cement mixer, long haul, short haul and coach applications, as well as urban bus and fire truck operation. A maintenance record form is included for tracking completed procedures.

Maintenance Specifications

This section gives the general engine specifications, lubricating oil system specifications (oil pressure, capacities, temperatures), cooling system specifications (coolant capacity, thermostat range, operating temperatures, pressure cap), Cummins/Fleetguard filter part numbers, diesel exhaust fluid recommendations and specifications, fuel recommendations and specifications, lubricating oil recommendations and specifications, and coolant recommendations and specifications. It covers fully formulated coolant/antifreeze, water quality requirements, coolant replacement requirements, and aftermarket oil additive usage. The oil drain interval tables for ISB6.7 CM2350 B103 cover up to 25 metric tons and occasional 32 metric tons drawbar applications with severe and normal duty oil types.
