1970 Massey Ferguson MF 40 Industrial (TPH won't come up)

[Rooftop Special]

Good Morning Guys,

A month or so ago I bought a 1970ish (the previous owner didn't know exactly what year) MF 40 industrial. When I bought it he said he had recently topped off the hydraulic fluid and the TPH hitch stopped coming up. I checked what I believe is the dipstick for the fluid (right side under seat) and it appeared low but not dry. I'm not entirely sure he used the right fluid. However the front loader works fine, I'm assuming it's all connected and uses the same fluid? I've tried every combination of messing with the draft / lifting levers with accelerated idle, etc. It has the three pedal type transmission with forward/reverse/neutral.

I've ordered the repair/owners manuals. Any help before they get here would be appreciated.

Thanks in advance,

Casey

Is it possible fluid isn't running properly past the loader valve to the 3 pt?

Did you try all the things I suggested in your thread in the repair forum back on 4/24? If I remember correctly from your pictures you have a front pump running your loader and internal tractor hydraulic pump runs the three point. You have an instant reverse transmission so I was thinking you needed to have the tractor moving to run the rear pump or have the tractor in neutral and step on the forward pedal or the middle pedal to power the rear pump. This is how the PTO operated on an industrial model I looked at so I am thinking the rear pump operates the same way. I never heard how this advice worked.

Hey namyessam,

I started the tractor over the weekend and stepped on the middle pedal while manipulating the controls and it didn’t do anything. I didn’t try it while moving as I have a flat tire right now (spun bead). I guess I didn’t realize you also suggested trying it while moving as well. I’ll try that next time. My issue right now is I’m only where the tractors at every month or so.

Thanks for the help,

Casey

Does the tractor have a gear shift lever that can be shifted in to neutral then step on the forward pedal. Does the tractor have a splined shaft sticking out of the rear housing above the drawbar? If it does, engage it in the engine position. If it has a designation for ground it will only run when the tractor is moving. Step on the forward pedal and see if it turns. If it does, the internal pump should be running and you should be able to lift the TPH. Like I said before, I am not that familiar with industrial tractors with the instant reverse but did look at one about 4 years ago and thats how it operated.

It doesn’t have a PTO. The previous owner said he added fluid and mentioned taking the Transfer Cap off to do so? Is this where you add fluid? Sorry for “silly” questions.

I read that inside the Transfer Cap is where you direct the fluid for a front loader, which my tractor has, could he have monkeyed something up with the Transfer Cap.

The unit is low on oil so I probably need to add some before further troubleshooting. It calls for M-1129A (or equivalent). What is a good fluid to use? I think I’m going to drain what’s in there, flush the system using diesel, drain, and re-fill with fresh fluid.

I’ve got both of the manuals now and I can’t find where the drain plug nor the where to fill it up at? I’m a very mechanical person and it’s sort of embarrassing to have to ask.

Thanks,

Many industrial tractors do not have PTO's. The reason I asked was to use it as an indicator for power to the rear pump. Does the loader have a large filter hanging off the right side of the loader frame? I thought that loaders with front pumps have the oil tank built into the loader frame and the tractor hydraulics used the transmission / differential fluid. I would be very carefull before buying any fluids for the tractor until you are sure of the correct fluid or you could seriously damage the internal components. From tractordata.com it looks like these tractors were made with three different transmissions. They may all require different fluids. It seems I ran across a thread for an industrial that used just automatic tranmission fluid for the oil. As for the transfer cap I am clueless. I would hope someone else would jump in here and help you out. Maybe you could PM Hutch and see if he has any better info on industrials. I think he goes by shona13. Sorry I cannot be more help.

I was reading through the manuals and you're correct. The front loader is operated by a pump on the front of the tractor that is driven by the engine crank. The fluid runs through the frame and it has the large filter on the side.

G'day Rooftop Special.
As far as the three point linkage the industrial Masseys have the same hydraulic system and yes if the previous owner removed the hydraulic transfer cap to put oil in he could have possibly not replaced the Standpipe back in the pump correctly ,an easy way to check is to:
set the tpl levers ,Draft in the UP/ fully back position ,The Position control lever in the transport Position, remove the 3/8 " npt plug on the side of the lift cover it is on the front right hand side Above the transmission/Hydraulic dipstick You will be able to recognize it because it has a Allen Key Drive ,It is in fact a Grub Screw.anyway remove it ,IMPORTANT PULL THE ENGINE STOP OUT SO THE ENGINE WONT RUN and crank the engine ,watching the hole and oil should come out of the hole
If oil does not come out remove the transfer cap, it is held on by two setscrews ,it is located just above the plug you removed,before removing make sure the lift arms are fully lowered and just to be safe lower and depressurize the loader they are not common systems in any way but just to be safe, remove the cap you will or should see the Hydraulic STANDPIPE Stick out about 3/8 Th inch if you can see nothing but a hole this means that the standpipe has fallen inside ,no big deal, remove the side plate Right hand side ,the one with the Transmission dipstick ,Warning make sure the engine stop is out and the key removed,put your hand in there and feel forward you should feel the pipe ,3/8 Th inch diameter by 12to13 inches long line it up with the hole in the cover at the top ,remove it and replace the O rings reinstall the Standpipe and put your left hand inside you will feel the hole in the pump where it fits in line the pipe up and put a Philips head screwdriver down the pipe hole and give the end a light tap enoughto compress the O ring into the pump ,Replace the O ring on the underside of the cap( same size ) replace the cap and she will work.

To drain the hydraulic/transmission there are two drain plugs ,both on the left hand side one roughly where your left toe is when sitting on the tractor and the other further back About where your left heel would be,the transmission holds about five gallons I use universal tractor oil here in Western Australia But we don't see temperatures below 5 degrees C I would not use Power steering oil the differential and gearbox ,hydraulics all use this common reservoir and in my opinion when the tractors were built there was no special oils required so keep it simple.

Th transmission oil fill point is on the left next to the gear stick speed change lever.

The Power shuttle transmission has a charge pump which is driven by the flywheel via a splined connection and is for the purpose of this discussion much like an automatic transmission in an car except you have four forward and four reverse gears.
The transmission unit uses Dexron 11 ,or locally available automatic transmission oil and is filled via the filler hole next to the trans control pedals about 2.5 gallons.
hope this helps yourself and other members who have similar problems.
As always.
Happy Days.
Hutch.

Hutch...........Thanks a lot for the info. I finally got the loader to work because the standpipe was not in the right position in the pump. I did not know about this until I read your post. Many thanks. Brian
