Best looking restoration that I have seen in a long time . Complete with weights the much better looking square front axle, fenders , PTO covers, 800 series hitch etc.
 
Looks really good! Were you able to find a supplier of the "patent decals"? There should be a decal in the front center of the battery box and the air pressure decal on the left side of the battery box. The auxillary power outlet on the right rear corner of the battery box should have a "6V" decal as well. In J.R. Hobbs book "John Deere Tractors: The First Numbered Series" he has a studio photo (dated April 1955) of a 70 diesel showing the spokes on the steering wheel to be green. How many hours did it take to do this first class restoration?
 
It has all the decals on it now, I just did not have them on when I took the photo. I am not sure about how many hours, but It has been in my shop for about 4 months and I worked on it 5 to 6 days every weak. Some long days and some short days. I would guess I averaged 30 to 35 hours a weak... Dang I am retired!! I am going to have to go back to work somewhere so I can get some rest.
 
I rebuilt the ignition system for the pony motor, also installed a new clutch in the pony motor 2 times (the first one failed after about 6 starts. The pads on the clutch came lose on both sides. glue???) I installed new seals in the pony motor transmission as well as the brake. Turned the flywheel starter ring 90deg.(Bad places in the teeth)and replaced the fiber thrust washers and reset the end play on the crank. Replaced the cam gear(broken tooth). Replaced bearing in the governor drive gear. Rebuilt the water pump. Installed a new rad.core as well as several gaskets and other odds and ends. Its a lot of work for an old retired man working by himself. A lot of time was spent on cleaning parts and getting them ready to paint.
 
This is not my tractor. This is a customers. I am retired and I do this type of work to keep me busy. He is going to show the tractor.

I can see why . A magnificent restoration and attention to detail .
 
I don't think I see that U-shaped piece with a hole in it that slips down on the crank on the 800 hitch and keeps the crank from turning. You lift the piece up to adjust the hitch. If it's not there, the crank can turn a bit towards the seat and catch under the seat box when the hitch is being raised. Don't ask how I know! PC397 covers the 800 and 801 hitches. The part I am referring to is shown on page 4, #9. It is called a clip and the part # is 31593A.
 
Well, not so complete. I was rechecking all the fluids before the customer took it home and found the crankcase over full and the power steering empty. Now I have to pull the power steering pump and put new seals and maybe more in the pump. Wile trying not to knock all the paint off. Anything special I need to look at wile inside the pump?
 
Check to make sure the shaft is not grooved badly. Also, check to see if the seals were installed correctly. Maybe it has been leaking for a long time.
 
Sorry to here that. When I had the same problem on my 70 gas std. I did replace the main shaft although no obvious grooves were found. When I resealed the pump on my 80 I did not put in a new shaft and it still leaks some.
 
A new shaft costs about $260, but you can get a completely rebuilt pump for $450 from a company in Michigan (Owasso)
 
The pump was in a mess. When I opened the pump I found that sometime in the past the key had sheared and the shaft had spun in the gear. They had welded up the groove that had wore in the shaft and turned it back down. They cut key slots in the shaft(one on both sides) and used what looked like the flywheel keys from a briggs lawn mower engine. They used double seals on both ends but the shaft was grooved bad. The gears looked real good but the bushing on the input end of the shaft and the bearing on the output end were questionable so I ordered them too. Hopefully it will make a good pump when I get it back together.
 
With all of the required parts to rebuild the pump you can see why rebuilt ones cost $450. Did you get all the parts from John Deere?
 
Got all the parts from John Deere except the shaft. Got the shaft aftermarket for around $250, The shaft alone from John Deere was over $400.
 
Still amazes me that you can get all the parts to from JD to rebuild a power steering pump on a tractor that is 64 years old.
