The Fordson Tractor Pages Forum

Hello to all. I put the raised pto on last year and after use I see I have a leak. It does not show in this pic , this was before use. I have to find my manuals on this repair but wanted ask if I will have to take it back off to put the seal on the upper drive. Thanks for all help and info.

Hi Gerald
I'm Just working on repacing the seals in my regular pto and your unit is on the same page in my power major parts book. it looks like you might only have to drain the axle oil if the level is higher than the shaft, Then undo the ring of bolts that hold the shaft flange and draw it out. there seems to be the pto shaft with a gear on it and a bearing at both ends that appears to be press fitted only. I am assuming that this shaft/ gear will come out without taking the rest apart. The seal is part no E27N 7305-A which according to my book is the same as the standard seal for the regular PTO shaft. I just looked on a well known auction site and there is a guy in the states that has them around $22 plus shipping .
I hope this helps
Regards Robert

Thanks Robert, I have not been able to be on my power major much this winter, too many other projects but I have manuals from this site somewhere. The raised pto is great addition, I was always worried before raised pto when I was having to raise bushhog while it was spinning. Now one move to the lever and pto stops spinning but still have lift. Thanks again for the info.

hello gman

it is possible to take out the upper shaft only

( about a year ago ) i orderd a new sael for it, and if i'm right it's the same seal as the normal pto shaft

Thanks janus, all help is greatly appreciated.

Hello to all. I went to the local new holland dealer and he had the seal in stock, how about that. I thought a little high on the $ amount,$32.00 us $'s, but this place is known as being high on their prices although I try to do business with local companies. I found my repair manual, have not looked at it but I believe I can park on a slope to let rear end oil flow forward and should not have to drain any, we'll see. Good luck to all and again thanks so much for this site and the help I have received. Ole Blue would not be up and running if not for all the help. Thanks again.

I just looked at repair manual and the way I read it once I remove retainer the seal will be there either on the gear shaft or maybe in retainer, should not even have to take upper gear shaft out. Of course most of my projects always seems to have something go wrong, just last week doing my brakes on car I had my girlfriend be there to take a few pics if I needed to look at them to put it back together. I fixed one side and went to other side and floor jack would not work. I asked her what's the odds of this and she stated 99.9% because every time you do something there is always something that goes wrong. Anyway if there is any advice on this repair all help is appreciated.

Help needed on removing the seal. The seal is inside the retainer and I don't see any clips to release to get it out or anyway to press it or pull it out with the way the retainer is made around the seal. I don't want to damage the retainer by not knowing for sure how the seal should be removed. I'll get pics of it up a little later. Any advice is greatly appreciated.
Thanks

Hi
The seal wont be on the shaft it will be in the retainer its a tight press fit in there. It also has the bearing behind it as you look from the back of the tractor so it wont come past the bearing if that's tight too, it will depend on how tight the 2 support bearings are in there housings or on the shafts as to what will come out when you take the retainer off.
You could end up with retainer and shaft as one lump, If the rear bearing is the loosest interference fit in it's housing.
You won't know until ya try what way it will come out.

when its apart make sure the bearings don't turn in the housings or on the shafts as they can wear and become loose on both parts. I just had a green colored tractor in the shop for pto work and it had done this. Parts where $5000 Tractor worth $6000 so it got a $1000 in new parts and a pot of bearing fit for $60 which is what the guy wanted to spend .

Yes the hill idea works but a couple of times i tried it i needed more parts and by the time they came in it was raining and it delayed the job longer than having it in a shed and draining the oil, Plus I was working in mud putting it together .
I guess my luck is as good as yours . Like an old guy said once if it wasn't for bad luck id have no luck a tall some days .
Regards Robert

Thanks super. The upper shaft and bearings are in great shape, they are separate from the retainer and seal. Only the seal is in the retainer and it is in bad shape but just don't see how it would press out. Like you it is starting to rain so got to get tools inside. The part I have has the correct number on the bag and it appears to be correct as to size, both inner and outer dimensions. Thanks for the advice, I'm looking for another manual thinking it may give info. Thanks again .

Hi
ok to get the seal out you have to either try and punch it out from the back with a bar at an angle in the seal ( work from the end where the pto shaft is) or use a small chisel and carefully Peel the seal in to the middle and loosen it in the housing (working from the rear axle side). You Will have to be carefull not to damage the casting where the seal fits in when doing it. You have the new seal to use as a guide to whats in the housing which will show what ya hitting out .
I hope this helps ya. I got to head and look at a green tractor that wont move( transmission failure ). so i wont be around much more till monday But im sure someone else will help you if needed.
Regards Robert

Thanks again super. I have some pics now. Everything came out with no problems I'm trying to make sure I don't damage retainer, I'm having a hard time with the fact that the first lip is overlapping the seal and solid metal piece thats under the lip of the retainer Seems the solid part of the retainer would get damaged if I beat the seal out.

Anyone know if maybe the first metal piece that is under the lip of the retainer is the way the original seals were made?
The gear and bearings look in very good shape
Thanks for any and all advice.

The seal will have to come out the inside of the retainer, Gman. Working from the outside,put a small punch through the hole and lean it over at a 45 degree angle or more, so that the end of the punch sticks in to the rubber part of the seal, then drive it out. You may have to move the punch around and do this in several places.
You can also use a heel bar or seal puller from the back of the retainer. Tap it into the soft part of the seal, and pull it out like you were pulling a nail.

You can also screw some sheet metal screws into the metal part of the seal and pull it out with a claw hammer or wrecking bar.

Thanks JC. I used a punch but it is bending the metal piece that is shown where the screwdriver is pointed. URL=http://imageshack.us/photo/my-images/716/img9611e.jpg/][/URL]
The new seal appears to fit right to the retainer. URL=http://imageshack.us/photo/my-images/9/img9615nk.jpg/][/URL]
The only way I see this metal piece coming out of the retainer is by making the metel piece unuseable again.
Thanks for all advice.

The metal piece is part of the old seal. Go ahead and drive it out.

Thanks JC, thought this was part of old seal but wanted to make sure before I destroyed it. Thanks to all for the advice and info. Got to make a gasket for the ring and hopefully later today she will be back together. Again thanks very much.
Gerald

Thanks to all for the help. The old seal was enclosed in metal almost like a bearing. New seal in and she is back together. All seems to run fine. I'll have to get out and run her with bush hog to see if the leak is taken care of.
Good luck to all.

Hi
Glad It all worked out for you. And Hope the leak is cured There is nothing worse than it re appearing 2 days later . Internet fixing is pretty hard some times its easy to go out in the shop and do this stuff when its your Trade but trying to explain it to a guy thousands of miles away i find sometimes its hard. and some times the part I have may be slightly different to the other guys . My PTO seal is different to the one you had or it was put in the other way round
Have Fun and stay safe with the bush whacker Looking forward to the good news .
Regards Robert

Thanks super, I ran the raised pto yesterday,no leaking, but without any load so we'll see. I did notice that it seemed to shift a lot smoother now, the old seal was in bad shape. Thanks again for your help.

Hi Halloween, maybe this post will help you on your pto seal.

Hello to all around the world. This is an old post but thought it may interest some new members. I think the seal looks to be good, after working the other day I still do not see any leaks around pto shaft.

I missed this thread first time round. Great descriptions of what to do and excellent photos. Have learned a lot. Many thanks.
Would love to find a raised PTO, but what are the odds on that?!
Best, Adrian.
