awemawson:
Back from your travels then John?

awemawson:
So the Speedi-Sleeves have proved a bit of a red herring. The one I originally ordered proved too long, the sleeve would have overhung the shaft shoulder by 2 mm where it reduces from seal diameter to bearing diameter. This potentially would not only have interfered with the bearing, but acted as a sharp edge when installing the sleeve. I realised this before it was dispatched and had it replaced by a shorter one that they had in stock.

Now I hadn't realised but the seal actually has TWO lips - an outer smaller one as a dust shield where the wear groove is, and an inner one 10 mm further in where the actual oil seal is. This seating is not noticeably worn, but the Speedi-sleeve wasn't long enough to reach it and having a 'one on one off' situation wasn't ideal :( There is a Speedi-sleeve listed that is the ideal length, but it's on 8 weeks back order :bugeye:

So rightly or wrongly I've decided to re-assemble it with the new seal and bearing and see what happens. If it leaks again I'll order the right sleeve and live with the leak until it arrives.

So I put the trumpet back to together today and managed to get it back on the tractor. To aid this I turned up a 'guide stud to help alignment.

Just got the brake and dif lock linkages to refit and it should (may) be good to go.

micktoon:
Its some job you have there Andrew , just for an oil seal , I hope to god it fixes the leak after all the effort of fitting the new seal, I will be keeping my fingers crossed for you :thumbup:

Cheers Mick.

awemawson:
Glad to say Mick that that phase seems pretty much over now (fingers crossed)

This morning I got the brake and diff lock linkages back on without too many issues - a few fork holes needed cleaning up, new split pins and she's back.

Replaced the screw on hydraulic filter - the back axle oil in most tractors is used as the reservoir for hydraulic implements)

Then I pumped oil back into the axle - all 47.5 litres. The filler plug is under the back of the cab, so even if you could get a decent sized funnel in it, actually pouring from a 25 litre drum would be pretty hard. So in a flash of inspiration I used my diesel transfer pump. This is a small submersible that fits through the drum opening and works off 12v DC (ie the tractor battery).

All went well pumping the first drum, then part way through the second drum oil started pouring out of the brake operating rod aperture. :bugeye: This is sealed with a little rubber boot - I think it's a daft design to have it below the normal oil level, but that's how it is. Turns out that the spring that closes the boot tight on the shaft was stretched. It now rejoices in a small ty-wrap holding it close to the shaft and seems ok. I would have replaced it in the normal course of things but they seemed unobtainable. However google found me one this afternoon, and I'll keep it 'just in case'. Continued pumping until dip stick showed full (oil previously never reached the dip stick!) and there were no immediate signs of leaks.

Then I fitted the Hedge Flail right hand bracket (this is what all this palavour has been about!) and put the wheel back. Drove it round the yard a bit, proved that the brakes still worked, and put it back on the loading dock to put the other flail bracket on.

No oil leaks from the wheel bearing seal yet, though it's very early days - there was a single drip from the brake rod seal, though that is likely residue from the previous leak.

So now at long last I can measure up the spacing between the flail brackets so I can start welding up the new flail mount - that will provoke another thread I'm afraid :lol:

vtsteam:
Good!!

i hope...
