Converting Early Nuffield PTO to Later Style
Вставка
- Опубліковано 21 вер 2024
- Anybody with a Nuffield built before 1960ish will have the early pto system where the pto comes in first and the hydraulic pump second which I find very irritating when using mounted pto equipment like rotovators and mowers. Here I convert my tractor to the later style where the hydraulic pump comes in first using parts from a later tractor.
We also had a Nuffield 10/60. It was a 1967 model. The most efficient part of this BMC was the PTO shaft. One of the disadvantages was that it did not lift hydraulically when the clutch was pressed.
great video i now know what to expect my 1060 pto is jumping out.
Thank you for sharing :)
Your information is very useful
Brilliant, I have a 342 and would like to make the same modification - thanks very much for posting this video.
3/42 & 4/60 already have this style of pto, perhaps your tractor has a replacement hydraulics from a early tractor.
@@montegoson I’m guessing it’s highly likely, many of them become Frankenstein hybrids over time and the previous owner didn’t have any history on it.
The lenkage that's at top won't engage to lower my lift on my Leland 384 Tractor. The lift comes up as soon as you start the tractor even when I move the lever to lower it.
Thanks Mike C
Quite normal for the usual back pressure in the system to lift the arms when the pump is running. Do they go down when you press down on them?
@@montegoson no
Ok it’s not a tractor im 100% familiar with, does it have position control or just the early draught control? I’m thinking draught control button could be stuck in.
Appreciate your wisdom.
Riddle me this… the Nuffield is a British tractor and yet you are referencing “standard” measurements during this video instead of metric (3/16”, 3” , 1 5/8” etc.).
Don’t get me wrong, I use standard measurements all the time. I am used to using a calculator to change metric to standard on my Leyland (and my Yamaha motorbike).
Just curious as to why you aren’t using metric in this video?
Thanks again for sharing your knowledge!
The world is a mixture of Imperial and metric measurements, and so are Nuffield’s. While the piston bores and most bearings in the gearbox are metric the rest of the tractor is Imperial. The spacing of the front axle bolts are 2 inches not 50.8mm. Even the liners that are bored metric, if you measure the outsides you will find Imperial decimal sizes that are easy figures like 4.300 inches as opposed to a metric figure like 109.23mm, writing or speaking the imperial figures it is far less likely that errors will occur! Besides all that if I was to cut a piece of wood or dig a hole, both would be measured in inches as any metric figure given to me would have to be converted to feet and inches to have any meaning to me, at the time I grew up England used feet and inches, £s, shillings & penny’s
@@montegoson I did not know that. Thank you!
What a pity Morris Motors didn't do this in the first place, or, did the worthy Dr. Merritt suffer the curse of hubris?
Bravo
I was under the impression the very latest pto that had the hyds live all the time, you only needed to engage pto. These where much superior to the old system, the were fitted standard from the silver roof leyland?
I’m converting to the later Nuffield style, not the Leyland style. I not sure if the type you refer to would fit the Nuffield castings.
i have a problem with my leyland 255 hydraulic .They go up well enough but once they're up they start going down a few inchs and then back up repeat repeat aman said its the flow valve can you help me
Thats normal for Leyland position control, could be a leaking internal pipe or worn seal on the piston but not the worlds greatest position control!
ameennn i new you where going to say that. is their a easy fix or have i to the back end
I have a Nuffield 10/42, one day I was brush hogging and hit a rock and stalled the tractor. I started it back up and kept going, no problem. When I was done I disengaged the pto and could never engage it again. I wiggle the shaft left to right by hand and try pulling the lever and it just will not go in. Any thoughts on what it could be?
Sorry that’s a mystery to me, obviously something has bent but no idea what it is.
Worth a shot, I’ll tear it apart and see what I find. Thanks for the reply.
what is the weight of the hydraulic power unit? Looking to change out the right rear seals and wanting to lift the unit with a chain fall.
tony gyuro Never weighed one but I would guess about 200kg
I have a 272 ,which i replaced the hydraulic unit with one of a 270 . Did a couple of days mowing with it , then got the machine gun noise . Do i need to replace the tube and shaft , or just the tube ? And then shim it as explained ? THANKS In advance.
Probably get away with adjusting the lever somehow so the tube engages deeper!
Great video how many Nuffields have your got ?
I have 6 running Nuffields
Hi! nice video! question: can I pull the axle for a seal-replacement the same way without risking bearings on the end of the axle to fall into the gearbox on a Nuffield 3/45? Cheers, Henri
Hi Henri, you have me confused this is a video about the pto shaft and you talk of pulling the axle to replace the seal! Do you mean the pto seal or the seal behind the wheel?
@@montegoson Good morning! I have pulled the axle a qwrt of an inch and dare not go further: what is the bearing on the end of the axle: a bronze "glide" bearing or a needle bearing. With the latter I run the risk of needles falling into the crankcase when I pull the axle out..... .On my 342 no problem: glide-bearing, but what kind of bearing is on the end in a 3/45? maybe you know. I've asked around but there aren't many 3/45's around here. many thanks and your video's are a great help. Both my tractors are still doing a good job on my little farm even though 60 odd years old! Henri
The pro- axle to change the rubber rings and file. gtz Henri
file=filt (stupid spellinghelp)
If you put the pto lever in the rearward engaged position that will stop the drive tube dropping, then the pto shaft can be pulled out of the rear of the tractor to replace the seals.
Interesting .Just wondering if you have a 10/60 hyd/pto housing on a 4/60 transmission
Could be 4/60 or DM4 hydraulic casing on my 6 cylinder DM4, but its certainly not a 10/60 casing as it only has 3 bolts holding the top link anchor casting!
Necesito saber como se arma la cámara 10/60
Hi, I have a 344 Leyland, do you know which seal is fitted to the PTO operation lever on the side of the gearbox.
thank you.
Andrew Thefarmer. I think standard is a fat O ring but there is a proper seal made that fits. but im in the middle of a field turning hay and have no idea of the size
The standard seal is a fat Oring, I think I replaced mine with a 1 x 0.5 x 0.25 lip seal
hola amigo, desde Venezuela tengo problemas con mi Nuffield 4/65 cuando acciono el TDF agarra un ruido en el croche suena duro.. que podrá ser..?
Sorry I don't understand a word!
montegoson yo tampoco entiendo tu idioma amigo, uso traductor de google para entender lo que dice.!!
Slm lar 10/60 1968 modele olurmu bana yardimci olabilirmisiniz
Are any of them standard or all 6 pots
6 cylinder Universal and the rest are 10/60's with 4 cylinder engine.
montegoson very nice we've got a dm4 but the engines stuck would you do a video of one of your standard ones, great videos by the way
What would be the point of a video of a standard 10/60?
montegoson just be interested to see a video of your 4cyl instead of 6
learn something new everyday, might be swearing on you viedio now, but shame solution isnt as straightforward/cheap for a major😧😂
