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
top.
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
head.
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.
CIRCULATING WATER AND RADIATOR COOL
ING SYSTEM
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
setting.
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.

Chamberlain manuals by Don

[11/04/19]  

Quite often I get requests for wsm`s for the Chamberlain C670 & the C6100. Personally over the last 20 yrs I have yet to see a paper wsm for these tractors.i think this is because by this time JD owned Chamberlain industries, Knowing JD as I do , its not surprising to me that there never were paper wsm`s for these 2 tractors, There were manuals on micro fiche for dealers, but I never managed to find a method to digitize such manuals.But all is not lost …Again just a personal view, I think both tractors were cobbled together to use up the parts Chamberlain industries had on hand Both the 70& the 100 are much the same , based on the Chamberlain 306 & the 354 tractors ,You could say the C670 is an update of the Chamberlain 306 & the C6100 is the update of the Chamberlain 354. The 70 having the Perkins 306 engine and the 100 the Perkins 354 engine. So if you want to work on the 70 or the 100, then use manuals for the 306 or the 354… hope this helps someone
