I have a correction to make, and I'm surprised nobody has pulled me up on it! I said that the pressure in the control circuit was 3000psi. Of course it isn't. It's fed from a low pressure port on the auxiliary pump and is only about 250 to 300psi. Still enpough to blow out the seals on the input shaft and fill the bell housing with oil though.
Amazes me how somebody's dreamed up the idea, designed it, built it, built the tooling to make it. Just boggles my mind. Maybe to some it's simple engineering but I just think it's Brilliant especially when you think how long ago this was developed....
It's a nice design, if it had been me, I would have had two hydraulic clutches and done away with the freewheel, but that's just me 😉. Thanks for watching.
I made 3 episodes and are still awake. Dry humour which I think you will get. Great explanation now I know why it may run of the hill if it is not put into the high position. Great work. Jeff Moore
Better part of 3 decades ago i went thru an Auto/Diesel program at what was touted to be the oldest Auto/Diesel Schhol in the US. Though my career path didn't exactly keep me turning wrenches professionally to earn my bread, i've never stopped being interested nor stopped getting my self greasy. That being said, you're delivering "Uni" quality content! An excellent teacher you are!
An excellent explanation of Multi Power and how it works with a let the dog see the rabbit kind of approach…..just goes to show what a remarkably simple yet quality piece of engineering it is….thank you Mr Fudd👍
I was watching just to know how the multipower works but after that kind of explanation i could start fixing it myself if i had one. Awesome videos. Keep up the good work.
Just now found this very good vid. My mf65 w/multi would kick in and out randomly under load. Found out the intake screen on the aux. pump was plugged causing low flow/pressure. Works great now and cost me nothing. Cheers.
Really good to see how it works having spent two summers as a youth driving a 165 multi power. Especially the explanation of the lack of engine braking in low. Ashamed to say that this was used to freewheel down hills, thank God no accidents resulted.
Thank you Clarence, a MF 65 ran away with me coz I had it in low when I was 13 and scared me. Now I know why. Lend your baking tray to Muck and get him to do the same job on an early duel power. I did a stint lecturing at Reese Heath college and converting what you know into terms a student can understand is a challenge. Cheers Jim in NZ.
Another reason for periodically switching to high is to lubricate the needle bearing between the input shaft and top shaft. Not so much of a problem on the mk2 box that you were working on, more so on the mk1 box
I wanted to say thank you for the wonderful explanation. I have been looking at purchasing a Massey Ferguson with multipower but shyed away not understanding the set-up. Now I'm intrigued and want one in my line up of equipment haha. Keep up the great work!!
Wonderful video series. I have a 185 with working multipower and its awesome to have. My father has a 165 with nonworking multipower and im going to encourage him to fix it after wathing this series. Thank you for these videos !
Thankyou Clarance from Dan in Ireland.,Multi power was a game changer.there were so many stories about masseys with multi power running away..everyone knows they were fast and you couldn,t tow start one. this clears everything up.
Thoroughly enjoyed series had 590 mp for many years mp worked as good as new after 7500 hrs, secret is to operate and maintain as said in handbook. Keep up the good work
Thanks for that, always wondered exactly how multi power worked. To digest everything you've said I'm going to watch all three videos together (again) without interruption from the grandkids 😊👍
I've just bought one of these. Your explanation got through load and clear. I'm yet to try the multi power. At the moment I can get high and low on the shifter, but only 1st and reverse. I'm imagining the 2nd 3rd selection rod is off its neutral position. When I get time I'll pull the fill plug for a look. Jono 🇦🇺
Very good , your tutorials are first class . So I have just been watching them again ! I have my 590 gearbox in bits at the moment as the multipower has never worked in my ownership. The slip rings have worn grooves in both the input housings so I have new ones ordered , together with slip rings and clutch discs.
Really good informative video, your clear explanation of how the Multi Power drive line works is really first class. I liked watching your video and compared it with my own videos I made when was overhauling my MF165 that I made for reference. Keep making good videos like this one.
Thank you for the conclusion to multi power how it works . Nice to see it out on the bench and explained clearly. I want a classic MF with multi power now !
Excellent work! Thank you for taking the time to do this. I found your series because I’m looking at a 135 that’s for sale near me and wanted more information on multi-power.
Thanks for this explanation, long-winded though it is. We had just a plain '66 MF 135 with no multi-power at home growing up but the manual always referred to the multi-power option without explaining the mechanics of it. I always thought it was engine power boosting My father had grown up working with horses and only adopted the Ferguson TVO in the early '50s after getting married and taking on more land than horses could manage. Apart from how to change the engine oil and squeezeing the brakes he never learned much about mechanics. And never let his sons do anything he couldn't do ! Multi-power is a quite sophisticated system - more sophisticated for example than the optional extra overdrives on large saloon cars at the time. The machining tolerances then were nothing to what could be done via CNC in the '80s let alone today. Of course tractors back then had to be "run in" handily for so many thousand hours before really putting the power down. Otherwise you risked engine seizure. The MF 135 carries such a lot of sentiment by small and medium sized farmers all across the globe. Fair due to the boys in Coventry🧚♂
Thanks for that great explanation of the multipower Clarence . I’m about to split my 590 and dismantle the gearbox. I’ve checked the input oil pressure and flow from the auxiliary pump (around 4.5 litres /min at 275 psi ) This seems to be in accordance with MF workshop manual. In any case the 4wd clutch and independent 4wd both work ok so I feel the problem must be with the input shaft to the gearbox. Never had so much fun !
I'm glad I seen this video I got a old massey I move hay with the mutipower has been repaired 10 times or more all I want is to hold it back down hill I'm gonna pull it down and weld it up now that I see what's up
Very interesting thank you. Now I know how it properly works! You get people saying it's a god awful system well I say it's only bad when those are people who don't know how to operate/maintain it!
@@Mc-beardy yes I agree! I've never had any problems with my 135 multi power but when I first got it everyone said to be careful with it. I really enjoy using it and where I live its relatively flat too
Thanks a LOT..........Now i know what the multipower IS........... and i can understand what it does........ i´m wery happy to have found this video :-)
Hi Fud-Weasel I was wondering have you come across a problem of the low range not working on 12 x 12 transmission on MF4235. The middle and high range is working fine. Regards Bernard
There were problems with a spring in the range selector on this transmission if I remember, it's been a long time since I saw one. Unfortunately if it is related to the spring you are looking at a £5 part and a £1500 labour bill because it's horrible to get to. I hope I am wrong and it is something simpler.
Excellent series and like many others I thought I had an idea of how it worked 🤔 how wrong was I ☹️😂 great video again lookin forward to the next one 👌
Hi, i used to work for a Massey dealer, we did loads of multi power repairs plus a few times we removed the system altogether from the gearbox using a kit from Massey that came with all new gears etc, which turned the box back into a 6 speed, one advantage of this was that you could now tow start the tractor
@@ClarenceFudWeasel Can remember dad fitting opico turbo kits to 590's when he worked at John I Fearns of Bakewell, later i worked with him at Windsor and Stephenson Tideswell, we fitted a few TB Turbo kits to 290's and 690's, can still remember the lovely sound they made at full throttle, good old days
You made clear the last tractor I had with multi power was an mf 270 it work pretty good on all fronts made sure I kept it in high going down hill never run it for too long in gear was a good tractor but I'm still trying to figure out how to turn a 1085 into a 4spd or maybe I'll just get a 699 instead thanks for the videos
Hello From Southern Victoria Australia, I Never knew about how you should not keep it in low too long, when I used to drive one for example when I cut hay I'd start off in low Multi power 1st or 2nd high then flick it up to high Multi power then when I come to a corner I'd always flick it to low to go round the corner a bit slower, the clutch when pulled apart looks similar to a motorbike clutch too, Lance Maskell from Bundy Bears Shed from up north in tropical Queensland did one up a while ago, he is doing up a Massey Ferguson 135 Multi Power and is putting a faster diff in it, I think he got the diff out of a 185, they do road trips and take camping gear with them, the one we had sat on 40km / 25mph at top speed, he was hoping to get as fast as 60kph / 37mph on the road.
According to the original design specifications, it was supposed to be driven in high and only switched to low for short periods when the going was heavier.
From memory, I think the 6 speed non-multi-power was dropped in the 500 series and later 100 series giving only the option of 12 speed multi-power and 8 speed.
@@ClarenceFudWeasel I was looking at a silver top 590 at the weekend that has never left the village it was first arrived at from new. My mate bought it at the nextdoor farm auction to him and its really in mint condition. It's got no multipower though hence the question. Cheers mate.
@@ClarenceFudWeasel I'm not sure, I should know I drove it back from the sale. I'll find out. One slight problem he's got covid at the min so i'm avoiding them like the plague.
I used to work at a MF dealer in the 90’s. If I remember correctly, Multi-Power was still available to order as a factory option for the earlier 300 series models
Excellent video, extremely informative, I'm shocked at how cheap to repair, can you please tell me how much oil flow and pressure is required? My 1200 MP slips a bit, I'm suspecting pump is very worn Thanks
The control circuit is supplied from a low pressure port on the auxiliary pump which as 250 to 300 psi if I remember, not 3000 like I suggested in the video 😯.
Just a few comments, I would think as the hyd seals wear the pressure on the clutch decreases (progressively) so there's less force on the clutch plates so will gradually slip and so heat up and warp etc. This system reminds me of the Haldex unit on 4x4s like LRs. I would think it's an item that needs servicing based on hours use. One point to ponder at design time, would it not have been better to have high speed as default (no hyd pressure) and low speed as the pressurised torque path? I like corrections, I know often during a presentation some data is best guess (based on experience) to keep the narrative flowing, and then later someone points out a (confirmed) revised data point.
So my multipower in my 1962 MF-65 worked fine for many years. Then I would notice that it would make some noise trying to switch from 3rd High, MP low to 3rd high, MP high on the highway. It got worse, to the point that switching to high seems to make no difference in any gear at any forward load. Here is what is weird. Switching to MP high going downhill DOES engage engine braking. Can you think of any reason that MP high would not engage in forward torque loads, but still does cause engine braking when there is reverse torque? Also (and possibly related): what oil should be used in the MF-65 transmission?
Thanks so much for the video. I have a 35 deluxe multi power. Was planning a fluid change but not sure what fluid to use. Is it different from the regular gearbox.
It's one compartment from multi power to differential so just a standard universal tractor oil such as Witham Qualube All Farm 3 or equivalent will do just fine. Thanks for watching.
Very informative thankyou. I will let you know what's wrong with mine when I get to it. Do you have to split a 590 to change the aux pump or is it accessible from the top cover?
You don't have to split it for the aux pump, but you will have to lift the back of the cab up to get the top cover off and it helps to be skinny! Thanks for watching.
Cab doesn't need to be lifted on a 590 to get the top cover off but you will need to remove the cross member. Auxiliary pump can't be removed without splitting as it is bolted to the plated drive from the front.
@@andrewplumb6189 No, I worked for a Ford dealer and a John Deere dealer over the years, but we always had Massey at home, which is why I collect them.
Hey! Great videos! I do have a question.. I have a 74 MF 165 w/multi power.. I only use the tractor for finishing mowing.. I seemed to have lost my pto power and the high range mutipower drive.. even low seems a bit weak. Any suggestions where to look first? Thanks..
If your 165 is fitted with the hydraulically actuated iPTO, it sounds like you might have a problem with the low pressure hydraulic system which operates the PTO clutch and the Multi-Power clutch.
@@ClarenceFudWeasel thanks for the direction to look in! Can that be accessed under the seat/lifting arm cover? I’ll do some reading in my service manual
@@brado8523 The auxiliary pump is under the hydraulic cover under the seat, you can check the pressure in the multi power cooler/filter pipes if I remember.
@Oliver Lee390 People used to do that quite frequently, I never understood why. By the time it's in enough pieces to weld, they might as well have spent $50 and fix it properly.
There aren't any I'm afraid. For pressure and flow tests, disconnected the feed to the multi power spool valve and plumb in an adaptor for your tester. It should be 250 to 300psi.
The actual control linkage is pretty straightforward. It's not precision engineering, the pins wear and the holes stretch, unfortunately half of it you need to split the tractor to check.
@@ClarenceFudWeasel the bottom of the linkage looks like a flat bar with a peg pointing down towards the transmission. The peg isn't connected to the transmission though.
Yes it can and will do….and dual pwr is quite a substantial unit for a tractor….worked for a plant hire company many years ago who ran a 7610 with a tanker for dust suppression….they would put any donkey on it and that is exactly what happened…. It totally mashed the dp unit up and filled the entire transmission with all the metal bits….looked like Gary Glitters boots…what a bloody mess it was
I have a correction to make, and I'm surprised nobody has pulled me up on it! I said that the pressure in the control circuit was 3000psi. Of course it isn't. It's fed from a low pressure port on the auxiliary pump and is only about 250 to 300psi. Still enpough to blow out the seals on the input shaft and fill the bell housing with oil though.

Can you think of any reason that MP high would not engage in forward torque loads, but still does cause engine braking when there is reverse torque?
Also (and possibly related): what oil should be used in the MF-65 transmission?
The first place I would check is for broken multi power clutch pack disks. It's a splitting job I'm afraid.
Argggh. OK, it is what it is. Thanks.
Thanks so much for the video. I have a 35 deluxe multi power. Was planning a fluid change but not sure what fluid to use. Is it different from the regular gearbox.
It's one compartment from multi power to differential so just a standard universal tractor oil such as Witham Qualube All Farm 3 or equivalent will do just fine. Thanks for watching.
@@ClarenceFudWeasel thanks alot.
Very informative thankyou. I will let you know what's wrong with mine when I get to it. Do you have to split a 590 to change the aux pump or is it accessible from the top cover?
You don't have to split it for the aux pump, but you will have to lift the back of the cab up to get the top cover off and it helps to be skinny! Thanks for watching.
Cab doesn't need to be lifted on a 590 to get the top cover off but you will need to remove the cross member. Auxiliary pump can't be removed without splitting as it is bolted to the plated drive from the front.
@@andrewplumb6189 Thanks, it's thirty years since I have done one. 🙂
Did you work for an mf dealer?
@@andrewplumb6189 No, I worked for a Ford dealer and a John Deere dealer over the years, but we always had Massey at home, which is why I collect them.
Hey! Great videos! I do have a question.. I have a 74 MF 165 w/multi power.. I only use the tractor for finishing mowing.. I seemed to have lost my pto power and the high range mutipower drive.. even low seems a bit weak. Any suggestions where to look first? Thanks..
If your 165 is fitted with the hydraulically actuated iPTO, it sounds like you might have a problem with the low pressure hydraulic system which operates the PTO clutch and the Multi-Power clutch.
@@ClarenceFudWeasel thanks for the direction to look in! Can that be accessed under the seat/lifting arm cover? I’ll do some reading in my service manual
@@brado8523 The auxiliary pump is under the hydraulic cover under the seat, you can check the pressure in the multi power cooler/filter pipes if I remember.
theoretically speaking......can you pull the MP pack and reseal it just by splitting a-la clutch overhaul?
I have never done that, let me check later and get back to you.
Can you get the multipower pack out without taking all of the top of the gearbox apart? Looking at a 178 with the multipower not working
In a word, no. You can only get the overrun clutch out from the top. Sorry to bring bad news.
@@ClarenceFudWeasel Apparently the pack was welded solid so that will be fun to get working, and expensive
@Oliver Lee390 People used to do that quite frequently, I never understood why. By the time it's in enough pieces to weld, they might as well have spent $50 and fix it properly.
Good video
Thanks for watching.
very interesting
Thanks for watching.
If you can give any information on parts and/ or repair for a 4wd or 4wt axle on a 168 thanks 😊
Is it the MF Cat 3 axle you have or the Four Wheel Traction that you have? I believe the 4WT was a Selene axle wasn't it?
@@ClarenceFudWeasel on what I could find on the Internet a four wheel traction, 4WT is on the axle
And one more question.....where are the test ports for MP?
There aren't any I'm afraid. For pressure and flow tests, disconnected the feed to the multi power spool valve and plumb in an adaptor for your tester. It should be 250 to 300psi.
What part of the multipower linkage can get loose or cause problems?
The actual control linkage is pretty straightforward. It's not precision engineering, the pins wear and the holes stretch, unfortunately half of it you need to split the tractor to check.
@@ClarenceFudWeasel the bottom of the linkage looks like a flat bar with a peg pointing down towards the transmission. The peg isn't connected to the transmission though.
doesent the shaft turn in the same direction all the time and the clutch takes 4 seconds to disonnect
The direction of the shaft doesn't change. Why would it?
I want buy a multipower pump can I find a new one ?
or just second hand is availabe ?
You should still be able to get a new one from Agco. There are also manufacturers in Turkey and India who still make them
Enjoyed this series my uncle was nearly killed by a multipower, I always thought it was a inherently poor design not understanding the actual workings
Tops
Thanks for watching.
dual power could go bang if put from hi to low at high speed with a heavy load pushing behind the tractor would multi power do the same
Yes it can and will do….and dual pwr is quite a substantial unit for a tractor….worked for a plant hire company many years ago who ran a 7610 with a tanker for dust suppression….they would put any donkey on it and that is exactly what happened…. It totally mashed the dp unit up and filled the entire transmission with all the metal bits….looked like Gary Glitters boots…what a bloody mess it was
I guess you could probably do the same to multi-power if you really worked at it, but I have never seen it. Thanks for watching.
