Description

Cummins KTA50G12 & KTA50G14 Engine Parts Catalogue – Aggreko M04300017-D

This is the complete illustrated parts catalogue for the Cummins KTA50G12 and KTA50G14 industrial diesel engines, released by Aggreko under document number M04300017-D and current at Revision D dated 05/10/2015. Every assembly on the engine is broken down into exploded component views with reference numbers, Cummins part numbers, part names, required quantities and, where applicable, dimensional or material remarks. It is the parts book a workshop, parts counter or field technician reaches for when a KTA50 needs a specific bolt, gasket, bearing, injector, turbocharger or cooler core identified before an order is placed.

Cylinder Block, Crankshaft and Main Bearings

The base engine section lists the cylinder block kit, cylinder block casting, main bearing caps and cap screws, plain washers, dowels, expansion plugs, drain cock, bearing supports, piston cooling valves and cylinder liners with their D-ring and oil seals. The crankshaft chapter covers the KTA50 crankshaft assembly, counterweights, connecting rod bolts, Woodruff keys and both crankshaft gears. The main bearing set chapter separates standard-size upper and lower main bearings, thrust bearings and the individual bearing part numbers used in a full rebuild. Crosshead, valve and cylinder head mounting hardware is listed in the adjacent chapter.

Cylinder Head, Valvetrain and Injectors

Here the KTA50 cylinder head is broken down into intake and exhaust valves, valve springs, rotators, collets, valve spring retainers, valve seat inserts, valve stem guides, expansion plugs and pipe plugs. Rocker lever assemblies, rocker lever shafts, bushings, cover gaskets and rocker housing hardware follow. The injector chapters cover the complete injector assembly for both G3/G12 and G14 ratings, injector cups, O-ring seals, filter screens, plunger links, tappets, top-stop nuts and the STC tappet repair kit. Injector mounting hardware, banjo connectors and oil transfer connections are also included.

Lubrication System

Lubricating oil cooler cores, O-ring seals, cover gaskets and lock nuts are listed with part numbers. The lubricating oil pump chapter breaks the pump into its housing covers, drive gears, shafts, shims and lockplates, while the tubing chapter covers supply and suction tubes, rectangular ring seals, clamps, brackets and the pressure relief valve components. Oil pan options with their gaskets, drain plugs, threaded inserts and adapters are shown, along with the oil level gauge, sight glass and temperature sensor. Oil filter head assemblies, bypass valve components, filter adapters and the scheduled oil sampling hardware close out the lubrication group. Oil control valve and STC oil connection/manifold hardware round out the circuit.

Cooling System and Aftercooler

Water transfer tubes with their retaining rings and O-ring seals open the cooling section. Water header covers, gaskets and captive washer cap screws are listed next. The aftercooler chapter lists the cooler core, cover gaskets, rectangular strip seals, mounting spacers and hardware, and the aftercooler plumbing chapter details the water transfer connections, hoses, dust seals and grommet seals in both early and late specifications. The water pump chapter covers the pump assembly, water pump gear, water inlet connections, drain tube and O-ring seals. The LTA thermostat housing is broken down over three chapters covering housing castings, thermostat seals, bypass and transfer tubes, wear sleeves, retaining clamps, brackets and flexible couplings. The auxiliary cooling inlet and water filter assemblies complete the circuit.

Air Intake, Exhaust and Turbocharger

The intake manifold chapter lists air intake manifolds (front and rear configurations), air crossover connections, T-bolt clamps, hump hoses, gaskets, mounting spacers and the intake air pressure sensor and adaptor. The exhaust manifold chapter lists individual exhaust manifold sections, V-band clamps, adapters, exhaust outlet connections, heat shields, flange nuts, lockplates and exhaust manifold gaskets. Turbocharger coverage is split by rating: the G14 50 Hz turbocharger is detailed as a complete kit with its bearing housings, compressor housing, turbine housing, impeller, diffuser, thrust collar, split ring seals, oil baffles, V-band clamps and repair kit; the G12 dual-speed 50/60 Hz turbocharger is listed with its mounting gaskets, O-ring seals, lock nuts and flange head cap screws. The turbocharger oil supply hose chapter includes V-band clamps, sensor adaptors and exhaust temperature sensors.

Fuel System and Electronic Control

The fuel manifold chapter covers flexible fuel hoses, fuel block connections, clips, threaded plugs, O-ring seals and banjo fittings. The fuel pump drive chapter lists the accessory drive support, fuel pump support castings, coupling halves, drive shaft, hourmeter drive gear, accessory drive gear, bushings and tamper-proof seals. Both HFO fuel pump options are covered – the G3/G12 pump and the G14 pump – together with Woodward and GAC control systems, including electric servo actuators, electronic speed controllers, coax stop valves, control rods, left- and right-thread rod ends, mounting brackets, fuel water separators and actuator cable harnesses. The electronic fuel control actuator chapter lists the actuator and its O-ring seals, and the fuel filter head chapter covers filter heads, adaptors, lockplates and male union fittings. Fuel pump mounting hardware, jaw coupling spiders and gaskets close the section.

Drive, Mounting, Starting and Electrical

Camshaft assemblies with their Woodruff keys, camshaft gears and thrust bearings are listed, along with camshaft covers and gaskets. The engine barring drive chapter covers the complete barring drive, Woodruff key, O-ring, retaining rings, barring gear, compression spring, housing and barring shaft. Flywheel and flywheel ring gear are listed with their retaining hardware. Starting motor coverage includes both the G3/G12 and G14 configurations with ground wire and mounting hardware, and the mounting starting motor chapter adds the starter flange covers. Gear covers, front gear covers, front camshaft covers, accessory drive covers and pulleys are all broken down with gaskets, bushings, oil seals, wear sleeves and keyway seals. Alternator, alternator mounting and adjusting link hardware follow. The vibration damper chapter lists crankshaft adapters, spacers, roll pins, hex flange head cap screws and both the yellow and blue 12-pad damper options. Engine support front and rear brackets, front support, L.B. rear support and R.B. rear support are catalogued with their Aggreko part numbers. The magnetic pickup chapter closes the catalogue with the pickup, adaptor and wiring harness.

Why This Parts Catalogue Matters

Ordering the wrong part on a KTA50G12 or KTA50G14 is expensive and slow. This catalogue removes the guesswork. Each exploded diagram shows how the assembly goes together and which reference number corresponds to which Cummins part number, quantity and remark. That means a fitter can confirm a main bearing size, identify the correct injector cup for a G3/G12 versus G14 rating, check whether a turbocharger oil supply hose uses the early or late seal specification, or verify a vibration damper pad count before the order goes out. For workshops maintaining Aggreko generator sets and other KTA50-powered installations, this is the reference that keeps the parts counter and the service bay on the same page.
