The UTB tractors were sold in the USA as rebadged Long tractors, here is a bit of info on them.
DESCRIPTION tractor manuals downunder manuals this is the Long UTB tractor
The engine installed in the wheel tractor models 360, 460 and 510, is a high speed
diesel unit with four strokes and three cylinders-inline. The engine crankcase is a cast
iron unibloc with dry type replaceable cylinder liners, and with the housings for the
crankshaft main bearings and valve tappets.
Helical-teeth timing gears, camshaft located in the crankcase and overhead valves;
intake valves are shielded to increase turbulence of the aspirated air. The power train
is driven by the crankshaft which revolves in four thin shell main bearings and
includes: Light alloy pistons with toroidal combustion chamber built in top, three
piston rings (two oil scrapers and one compression ring), forged steel connecting rods
and liners lubrication and a second one through the small end for piston cooling.
Aspirated air is filtered through an oil bath air cleaner.
Fuel is injected directly into the high turbulence combustion chamber built in piston
Double diaphragm fuel lift pump, double filters connected in series and water trap on
the first filter.
Injection pump of the plunger type with all speed governor and automatic timing
device: type Rotary,with fly-weight mechanical governor.
Separate four hole nozzles (360/460) or three hole nozzles (510) clamped to the cylinder
Forced feed lubrication from camshaft driven gear-type pump with built in relief valve.
Full flow filter screwed to the crankcase and provided with an internal relief valve
which bypasses the oil flow when filter is clogged.
A centrifugal pump, belt-driven by the crankshaft-mounted drive pulley, forces the
coolant flow which enters the radiator when the temperature reaches up to thermostat
The cold air drawn by the fan which is secured to the water pump hub, cools the
coolant inside the radiator. Direct electric starting with solenoid engagement, 12 volt motor and starting aid for low temperatures.
