Tractor fixing help

Orla K

I'll start off by saying I was asked to look these things up by someone, who isn't very internet minded and I'm not very tractor fixing minded.

It's a massey ferguson 675, the orbital unit is broken, I've had a look around and the only replacement part found is about €1000. So he's looking for a cheaper alternative, I found none matching online, maybe a few possible ones on ebay(don't know if they will match the model) but I have found plenty of seal kits.

So now the idea is that the seal kit may be able to fix it but the owner isn't too sure if it can be done. So my search for a youtube video showing how to replace a seal kit and that's about where I get lost in a pile of videos which have no relevance to tractors.
Can it be fixed? and is there any online guides to it?
Thanks

If you open up the unit, it should be obvious if something is broken or if a new set of seals will do the job.

Here's a guy stripping one down:

Doesn't look too daunting, just a few o-rings by the look of it.

The one in the MF 675 is a Danfoss, according to this:

...but it's unlikely to be too radically different.

AFAIK, you must replaced with identical unit (numbers on d end),by law
you wont be covered in event of an accident
