1T7XXX is just listed as D3400 engine, the SP could be many different things.
from the green color my guess it is ww2 surplus
The SP on the serial no. Is normally "special parts" so could be lift pump or governor modifications or it could be different flywheel to take an an automotive style clutch, there are a few of those rollers in th UK, I think they were brought over to help build the airfields in the Second World War

instead of perfection some times we just have to accept practicality
dont use zinc containing oils in this old stuff as the bronze gears and bushings dont like it and will be come chemically pitted. i personally use caltex textrans tdh (which is made for tractors and cane harvesters) it is a 75w-80 oil meets caterpillar TO-4 specs) in the gearbox and hydraulics of my d4 and torque fluid 454 in the final drives there is 434 for different temp range these are zinc free and safe for bronze gears. ask you preffered oil company tech service for advice or the equivalent to these oils.
i also use delo gold ultra 15w-40 in the engine.
That's neat 4sure, i like seeing powerunits in old original equipment like that. Looks like the main clutch might not dis-engaged by the looks of that fuel tank on the front??.
1Txxxx s/n's started with 1T7001 in 1942 and were only produced until 1945. What kind of main clutch and throttle does it use. Governor looks like it might be set up for foot throttle, possibly foot clutch also. I'd stick closer to original lubes. Straight 30 wt or even 40 wt detergent in the engine and 85-90 gear oil in gear train. By chance is there a worm gear involved with the finals?
it has a hand throttle with an identical hand throttle assembly as a d2, also a hand clutch.
i had never seen a Huber roller let alone one with a cat engine before i saw this one so i really don't know much about the roller side of it.
desperately after some manuals for the roller though

More photos please.
