Anyone who knows anything about the 4WD system on 1979 Massey Ferguson 148 4WD?

Hi, and thanks for your reply. Do you think it's possible to make only one new one from a workshop without it becoming very expensive? Do you know workshops that do this? Thanks Jan

See my argument is, that somebody made it many many years ago with lesser tooling than what is available today
Do you know of any machine shops in Norway they would be best

As @Mur Huwcun says other parts will be available or adapt to fit that's the fun of old iron you have to think outside the box

Thats a modified walterschied slip clutch. If you can repair the threads or drill and tap four more holes between the damaged ones the rest of the parts should be available

I have information on 4 wheel traction but will have to look it out.

I doubt that waltershield clutch would have been part of the original conversion?
In any case it's easily obtained now

Could you supply a picture of the front axle and front hubs for clarification of axle make.

I am so impressed and thankful of the assistance and help you all give. I have searched a little around Walterscheid slip clutch on Internet. They look very similar and I hope to find something I can use.

Be interesting to see a picture of the whole tractor, thought they stopped making the 148 in 1976.

Probably still made them for export
I'm sure they were still making 200 series cabless tractors in banner lane when I visited around 1991

Yes that must have been the case, MF were still making the 148 for export.

Thats an overload clutch and it will no longer work as the middle has been welded to the outside, it must of been fitted from new to protect from damage to gearbox,

it should be easy to make up a new one, buy a new same sort of clutch unit,
its the splines on the input end from the gear box that will be the hard bit,
might be a case of fitting the new clutch hub with the old spline on input shaft,

a good machine shop should be able to do this, measure where to cut to end up at same length when finished,
mark and cut excess off, drill a small pilot hole up the input shaft on new hub in the lathe, take out old center input shaft, turn down to a really tight 3 thou over sized fit in lathe, needs to be tapered a little on the end, warm with the gas the outer part of the hole in the shaft, press the outer splined part in to the hole in inner part in a hydraulic press, this will hold it straight, put into the lathe and tac weld on both sides, spin the lathe and let it cool, then put a good run on top and bottom, again spin the lathe to cool it
once this is done, a good run all round it will hold it, mount the outer hub in the lathe, mark the diameter of the 4 holes to hole the pto yoke on, by just marking a circle by just touching it with some tooling,
fit into 4 jaw chuck and it need a hole marked at each jaw, to get them evenly spaced out, drill and tap out the threads,
put it all back together and refit
