I am after an exploded diagram for the early Fergy post hole digger with the wide gearbox, and 2 loose side lifting arms.
There is no Id plate but the 4 holes and mark shows that it did once have one .
Pretty sure its the MF 723.
Thanks

Hi Charles.
Thanks for replying, yes that's the one.
Can you still get the input and output shaft seals for these.?
Local agco chap said to bring the old ones in, and they will match them up.
Am hesitant to do this in case they cant get them.
Am also on the lookout for a replacement pto shaft.
It was missing the male section with the spring loaded protection clutch. Is it 1' x 15/16' ?
Or if to replace the entire shaft, what is its measurements from closed to fully extended.
Thus, you see why I was looking for some drawings, or a parts manual for these details.
Thanks again.

I recently rebuilt the gearbox of one of these . They are very simple and will not give you any grief at all .
Yes the seal , both input and output are readily available at bearing shops , they cost about $20 Aus d each straight off the shelf . I was surprised as they are quite large and unusual looking things . The bronze bushes wear and score , you can dress these up a little with emery and fill the box with runny grease instead of oil to keep leakage down to a minimum . The original shaft didn't have a clutch , some owners fitted the one off the potato spinner that used the same gearbox . I have two of these post holers , neither has a clutch .
These photos might help , I can take others if you'd like .

Thank you for your prompt and helpful reply.
Great pictures, good to hear the seals are not made from 'Unobtanium'.
Do you have the part nos available?
Interesting to hear of the pto shaft not having the clutch, but was often substituted from another piece of equipment.
Want to make sure I preserve this equipment for future generations, and for some trouble free use for myself.
If you have the time, a brief overview of how it came apart, ie which shaft first, followed by any handy hints would be appreciated.
I realise we all live in the real world, and time is often scarce, but any further advice/ help would be appreciated by me, and I am sure by others also reading this.
Thanks again, and hope you have a good weekend.

No worries Trains
I wrote a detailed account of the dismantling on the Grey Fergie Forum here .
http://www.greyfergieforum.com/viewtopic.php?f=22&t=69&start=160
The hardest thing is the removal of the crown wheel , patience here is all you need .
The seal numbers aren't really that useful , the old one as long as it is still reasonably intact is all the bearing supplier will need . Just make sure that they understand that it is an Imperial size so they don't try to give you a metric one .
If you have any specific trouble just ask .

Hi Chaps,
Still looking for the measurement details of the male part of the pto shaft, and of the length of the shaft fully compressed, and fully extended.
If I can find an original pto shaft, that would be great, however to make something up to fit, I need the above measurements so I can order the correct pto shaft.
So if anyone has one currently fitted, can you measure from uni joint to uni joint when its in the fully extended position, that would let me know how much of the shaft is still left in the female part of the pto shaft.
Kind regards
Trains

I have only just today put the first coat of paint onto the shaft of the post holer I am working on at the moment . Once the paint is hard enough to handle tomorrow I can take further photos and measurements as well , The Universals are Hardy Spicer , the main shaft is a piece of 2' or there abouts steel tube and the sliding part is a section of heavy walled 1' square .

My hands are about to be operated on , they are giving me grief at the moment, so the focus is unfortunately blurry , it was the best I could do .
Some measurements , Fully closed , including universals the shaft measures four foot ten and one half inches .
Fully open with only about one inch remaining inside the sliding socket the shaft measures six foot three inches .
The bar is as you suggested one inch by fifteen sixteenths of an inch and is seventeen inches long . The universal joint and socket adds a further ten inches to make twenty seven inches overall .
The adaptor piece at the end of the pipe shaft is eight inches long , this receives the solid bar .
The pipe shaft itself is thirty seven and one half inches without the universal joint or the adaptor fitted , it is made from two inch medium walled pipe , much lighter than you would expect .
Hope this helps I am happy to clarify anything if you need it .
