New Holland / Case propshaft bearing

[norse]

The propshaft Bearing has failed on my New Holland T7.250, I am told that it will need a kit to repair this including the shaft,bearings and housing etc,whilst researching online for the options I have found that these repair kits are available from spurious suppliers including QTP,I just wondered how the quality of these components compares with the genuine new holland ones ?

Unless the spurious kit has oe spec bearings etc in it, I wouldnt trust them.

It must be gone a long time if you need the shaft?

when the bearings fail it damages the she shaft and housing so is all supplied as a kit,the genuine new holland kit includes the prop to the front but the spurious ones just have the short stub shaft,I was asking about the quality of the kit mainly the bearings.

It's only the key way that fails in them normaly let's front bearing housing spin and undo axle retaining nut. If it's not gone too far you will just need new bearings can get bigger key way machined in old housing. You don't need to take axle out to get them out just pivot it back bit of a fiddle nut can do them in about 4 hours

If it’s the support bearing mine went at 4000 hours. Axle off job. Resulted in a £2500 bill. I am not happy as the tractor this one replaced covered 11500 hours with no issue in this department. I seriously question these failures especially as all this kit rises in price.

Short shaft spline overlap was i think increased to cope with axle suspension near end of travel, prop balanced to higher speed, uj's were sealed for life although can be replaced with different suppliers and same goes for the support bearings.
I usually go for known branded bearings where possible albeit thats not failsafe in todays world of outsourced components.

went with genuine New Holland in the end as it comes with front prop as well,the nut and bearing support housing are modified to lock the nut better,it was the front bearing that had failed and the nut was still tight! got it all stripped yesterday,managed to drop the axle support down at the back to give room to work will have to split the uj on the prop and fit back together in situ with a g clamp,bit of a fiddle but easier than removing the axle.

You can get the prop off completely if you drop the back of the shaft down a lot with the front tyres nearly off the floor. Take the whole shaft out and swap the UJ in them for greasable ones.

Good man it's much easier to do it without taking axle out not too bad I normaly use the old prop shaft cut the old uj to get it out and put a new one in situ when putting it back together

 

[norse]

Uj's were fine, I don't think there is room without removing the axle support or splitting the uj

 

[lexion780tt]

If you split uj will come out a treat if tight just enough room to cut uj with thin cutting disc

Any chance of some photos, planning on changing the bearings on ours this winter as a precaution.

The end of the yoke on the prop was damaged as we had to move the tractor off the road as it was about to shut due to a cycle race so it had bruised the end of the prop against the sump and axle carrier,i just cut uj out,the biggest job was removing the nut on the housing that carried the bearing housing

Ill get a few,hardest thing is stopping to take some when your hands are filthy, I have a service bulletin that I can email to you if you send me your email address,it details how various parts have been improved,mine was the bearing that failed without any warning,there was a slight noise and then a lot of noise and smoke a mile further!

That would be good thanks, I will pm you now!

 

[PSQ]

Check that the repair kit contains the latest spec parts, as NH sell both the original light bearings and carriers and the later beefed up parts to upgrade the earlier machines.
Ours failed at 2,400 hours on a T6080 while ploughing. Put it down in part to the auto 4wd kicking in / out on endrigs when it senses steering angle.

It is the latest kit that has the four studs to anchor the nut that holds the bearing housing on, had to make a socket to undo the nut on the housing,it was quite a struggle to get undone

Here are a couple of pictures

My socket made from a 3/4" socket a bit of tube and 2 bits of key steel, unfortunately I had to sacrifice a good socket as I needed one that's a good fit inside the tube,it must be ok as it's has the 3/4 Milwaukee impact wrench hammering at it for a while to get the nut undone
