Scott, maybe you have checked it but I think there is a gearbox that has a fill point in the floor of the cab, next to the clutch pedal. Make sure that has TO in it up to the elbow. I think it is to lube the worm gear from the drive shaft to the vertical control shaft in the knuckle buster box.

There is a seal assem. between the starting engine and head to seal the water passage. The one for a D4400 is 5B7780 but don,t have a book for a D3400 like the 212 has but they could be the same, not sure without a parts book as they are the same starting engine but not the same diesel.

what does this unit weigh ?? i was guessing 13-14000k beforei hauled it maybe 16-18k after it seemed a little heavier than my td-40 {could have been how it was loaded too}anyone know ??? thanks --scott

I show a shipping weight for basic unit of 13,130 lbs.

My book shows 1U-166 to be built in 1946, 1 -- 218. catskinner

Hi catskinner,
I checked again and you are right.....must have missed a line;)
Does show production into 1947 with 219 - up but no high end count.
Still a pretty rare low production model although there doesn't appear to be anything unique about it.

Also lots of publishing errors in various sources....some don't even acknowledge the 1U model, some claim it to be single drive instead of tandem:rolleyes:

is the power assist steering oem on this or was it an addon ??? it looks like oem parts but not oem installation maybe an addon or upgrade IMO --- scott

SJ is right, 5B7780 is the seal between the pony and the diesel water jackets for a D3400 engine.

The 212 graders older than 9T308 didn't have a shear pin in the control box vertical drive shaft.

Your gear box in the floor will have a pipe plug direct into the box instead of an elbow and a plug like the later graders had. Should make it easier to fill, 90wt gear lube goes around that elbow S L O W L Y!

The Operation and Maintenance instructions book I have lists your grader and is a Form FE034351-01.

The steering box adjustment is mainly done by taking the top adjusting nut off and removing shims beneath the two half nuts and then replacing. I believe this would lower the "rack" or driven gear sector so it's tapered teeth fit tighter into the worm. Be very careful after you adjust it so you don't over tighten it and put the box in a bind. The other thing to check is that the worm shaft does't have any slack in the bearings. Shake the input shaft from the steering wheel and eliminate any endplay by removing shims under the end cap.

Power steering units are not listed as an option or attachment in the parts book even on the later 9T series. I think they were all aftermarket units.

anyone know of a parts house that might have one of these seals in stock and can ship it direct ??? these morons in az have to ship it in from la then verfiy i still want it even though i have ot pay for it up front then they will ship it to me 10-14 days ---thanks

got it ordered --scott
