0The John Deere 6359T is a 5.9-liter,
six-cylinder turbocharged diesel engine belonging to the John Deere
Series 300 family. Produced from the late 1970s through the 1980s, this
power unit served as a primary power source for mid-sized agricultural
tractors, combine harvesters, and various industrial equipment
applications.
The 6359T represents the forced-induction evolution of the naturally
aspirated 6359D engine, delivering a significant power increase while
maintaining the same compact footprint and robust construction. This
engine is distinguished by its replaceable wet-type cylinder liners,
forged steel crankshaft, and mechanical fuel system, characteristics
that made it a preferred choice for operators requiring durability and
serviceability in demanding field and industrial conditions.
The 6359T engine is a four-stroke, compression-ignition diesel unit
featuring an inline six-cylinder configuration. The engine employs a
turbocharger to increase air density entering the cylinders, allowing
for greater fuel combustion and subsequent power output without
increasing displacement. The bore and stroke dimensions are nearly
square, a design choice that balances torque characteristics and engine
speed capabilities. Rotation is counter-clockwise when viewed from the
flywheel end.

The cylinder block is constructed from high-grade cast iron, featuring
an open-deck design that accommodates replaceable wet-type cylinder
liners. These wet liners are manufactured from centrifugally cast iron
and are in direct contact with engine coolant, providing superior heat
dissipation from the combustion zone to the cooling system. The block
incorporates seven main bearing webs supporting a forged steel
crankshaft, a configuration that distributes combustion loads across
multiple bearing surfaces for enhanced durability under turbocharged
pressures.
The crankshaft is both statically and dynamically balanced to reduce
vibration during operation. Connecting rods are forged steel, selected
for strength and durability under sustained turbocharged diesel
operation. The wet liner design allows individual liner replacement
without removing the engine from the equipment frame, enabling in-frame
overhauls that reduce maintenance downtime.
The cylinder head is manufactured from cast iron and utilizes a
cross-flow design with intake and exhaust ports on opposite sides of the
head. The combustion chamber is of the direct injection type, with the
bowl-shaped recess formed in the piston crown. The valvetrain employs a
single camshaft located in the cylinder block, operating the valves
through pushrods and rocker arms. This overhead valve (OHV)
configuration provides two valves per cylinder - one intake and one
exhaust - arranged in a vertical orientation.
Valve Arrangement: 2 valves per cylinder (1 intake, 1 exhaust), overhead
valve.
Camshaft Drive: Gear-driven from the crankshaft.
Valve Lifters: Mechanical flat tappets.
Valve Seat Inserts: Induction-hardened steel inserts for both intake and
exhaust valves.
The fuel system is a mechanical injection system designed for diesel
combustion. A Stanadyne / Roosa Master rotary distributor-type injection
pump is mounted to the engine and driven by the engine timing gears.
This pump generates high-pressure fuel and distributes it to the
individual injectors in the correct firing order.
The injection pump incorporates a mechanical governor to maintain engine
speed under varying loads. Mechanical injectors are positioned at the
cylinder head and inject fuel directly into the combustion chamber
recess in the piston crown. A fuel transfer pump, integrated into the
injection pump assembly, draws fuel from the tank and supplies it to the
injection pump through a filter assembly.
Injection Pump Type: Stanadyne / Roosa Master rotary distributor pump
Governor System: Mechanical variable-speed governor
Injector Type: Mechanical pintle-type
Injection Order: 1-5-3-6-2-4
Fuel Filter: Spin-on type with integral water separator
Fuel Lift Pump: Mechanical diaphragm type driven by the engine camshaft
The lubrication system is a full-pressure, wet-sump design. A gear-type
oil pump, driven directly from the crankshaft via a gear train, draws
oil from the cast iron oil pan through a strainer-type pickup tube. The
oil is pressurized and directed through a full-flow spin-on oil filter
before circulating through main oil galleries to the crankshaft main
bearings, connecting rod bearings, camshaft bearings, and valve
mechanism.
The turbocharger receives pressurized oil through a dedicated supply
line, with oil draining back to the crankcase via a gravity-fed return
line. A pressure relief valve maintains system pressure within operating
limits.
Oil Capacity (with filter): 13.2 L (14.0 qt)
Oil Capacity (without filter): 12.5 L (13.2 qt)
Oil Grade: SAE 15W-40 meeting API CD, CE, or CF-4
Oil Pressure (Rated Speed): 345 kPa (50 psi)
Oil Pressure (Hot Idle): 105 kPa (15 psi)
The cooling system is a pressurized, thermosiphon-resistant design
utilizing a centrifugal water pump mounted to the front of the cylinder
block. The water pump is belt-driven from the crankshaft pulley. A
wax-pellet thermostat regulates coolant temperature by controlling flow
between the engine and the radiator.
The cooling system is designed to accommodate the increased thermal load
generated by the turbocharger, with coolant circulating through the
cylinder block surrounding the wet liners for maximum heat transfer. A
mechanically driven engine cooling fan provides forced airflow through
the radiator.
Coolant Capacity (engine only): 18.0 L (19.0 qt)
Coolant Capacity (engine with radiator): 24.0-30.0 L (25.4-31.7 qt)
Thermostat Opening Temperature: 82 °C (180 °F)

System Pressure Cap Rating: 70-100 kPa (0.7-1.0 bar; 10-15 psi)
Water Pump Type: Centrifugal, belt-driven
Turbocharger: A single turbocharger is mounted to the exhaust manifold,
utilizing exhaust gas energy to drive a compressor wheel that
pressurizes intake air. The turbocharger is journal-bearing type and is
oil-cooled only.
Intake System: Intake air is drawn through a dry-type, dual-element air
cleaner with a safety element before entering the turbocharger
compressor inlet. Compressed air then flows through a cast iron intake
manifold to the cylinder head ports.
Exhaust System: A cast iron exhaust manifold collects exhaust gases from
the cylinder head and directs them to the turbocharger turbine inlet. A
dry exhaust stack or muffler is mounted downstream of the turbocharger.
Electrical System: 12-volt or 24-volt system depending on application.
Heavy-duty alternator rated at 40-55 amperes and a starter motor of
approximately 3.0-4.0 kW.
