D68U Need info

Would really help if you can post the s/n of the blade....I can most likely tell what's needed from that as there are a few combinations.

Thanks OM. He can't find the s/n on the blade. I'm supposed to meet him later today to look at the machine. I'll see if I can find it.

Hi, Invisibledog.
If my memory serves me rightly, the serial # on those blades was usually in the top right corner, within about 1 foot of both the top and the right side. There was a stamped aluminum plate rivetted to the back face of the blade with the number also stamped into the back of the blade under the plate, in case the plate somehow went missing, possibly due to some past carelessness (???????????????).

Hope this helps.

No sign of a s/n anywhere on the blade. It has been repainted several times, so the numbers may be filled with paint. If there was a tag it is long gone. I took some pics, with the owners camera, of the blade and some part numbers on some of the brackets. Hoping to id it that way. I'll post some pics as soon as he emails them to me.

See if you can spot any numbers on the hydraulic cylinders, sometimes you can back in to id that way.

I didn't see any numbers on the cylinders, but I did finally get some pics. Maybe these will help. If not I'll have to make a trip to the machine for another look to see if I can fine some numbers.

From what I can see you have the 15C5001-up blade s/n C-Frame which is a combination cable/hydraulic version (has cable pulley mounts) but the upper blade braces suggest the blade is from the 9E1-up blade s/n hydraulic only version.

Back to your original request, there are no bushings that are replaceable.
The trunnion mounting ball is the same as the D4, D5 & D6 along with the same bearing and cap. The usual fix for worn trunnion bearing is to torch off and weld on another cap rather than cut the whole thing out.

Thanks OM. I'll pass the info on to the owner. He restores aircraft and makes replacement aircraft repair panels and is very particular about his stuff. I can see him making replaceable bushings and pins for it.

That is one very tidy tractor for 1955 build
Unless there is slop in the hydraulic ram eyes the rest looks almost as new.
Tolerances are not the same as in aircraft. The tapered pins for adjusting blade angle need to slip in easily to save fighting with them when changing the angle especially if there is dirt stuck to the blade putting it out of balance.
Would like to find one as good as that.
