Hi. Here we go with the latest problem for you to apply your brains to.
I started to fit the hubs to the front axle. Now I thought they would fit easily onto the stub axle but this was not the case. Should the bearings (especially the outer one) need a tap on the inner race to get it seated? I did this and it went on but then there is no end float so that can't be right. Then it was a real bugger to get off again when I decided that things were just not ticketyboo.
So when it was off again I tried it on the other stub axle and it slid straight on.
Now the bearings are all new (part number RTC3534) as is the stub axle they don't fit on. The stub axle they do fit on is the original one just with a new collar fitted for the oil seal. The new stub axle is part number 599827. All the parts are Britpart (yes, I know).
So how is this sounding? Is the new axle at fault or is the old one worn out? Do the bearings need a bit of persuasion or is an absolute no no? If you do tap the bearings home and they are tight how do you get the correct end float?
As always i'm grateful for any opinions. If you want to see the story so far have a look at my rebuild thread.
Thanks.
 
I've just been doing an axle today. I'd got a bit of overspray on one of the stub axles and that was enough to make the bearing too tight. You want it tight enough to be happy that it won't spin on the stub, but not so tight that the pre-loading won't work with confidence. Sounds like you're pretty close, if you can't feel any burrs maybe just a go over with some wet and dry until you're happy.
 
My money is on the new stub axle slightly too big but the only way to tell is measuring it.
I can probably get time to do that tomorrow. The only problem is that I don't have a known 'correct' one to compare it to. All the others are the existing ones so may well have some wear.
I still have all the old bearings and the old stub axle so I will probably just have to do a comparison of which bits fit each other. It's going to be a bit of a bugger if I have to take the stub axle off again though.

I had been thinking about this overnight and I fancied having a go at the axle with some abrasive. I've got a roll of emery paper and I could get a good even action going. Is emery too abrasive? Should I stick with wet and dry?
 
[QUOTobsticle, post: 3820182, member: 103730"]Hammer them in. The britpart bearings will self destruct anyway within 10000 miles. :p[/QUOTE]
Fair comment
 
Later stub axles have different bearings to early stub axle with land if I recall correctly.
You are spot on. Old stub axles are no longer available so you automatically get sent the later type but the bearings are different. I have spoken to Paddocks and I can send back one of my unused hub bearing kits and get the right ones.
So now this hub has got the wrong bearing races fitted. Do I remove them or just use that hub on the rear later and build up one of the rears to use on the front?

I'm a bit late to the party on this thread but I noticed that problem too.

The newer stubs get sent out and you need the newer half shafts to go with them. Pain in the arse.
 
I didn't know you needed new half shafts as well. Fortunately I needed new front half shaft outer ends for both sides anyway or I would now be scratching my head as to why they didn't fit either o_O

I'm not 100% sure about it myself as I'm not at the stage of reassembly yet but have been reliably told the whole shebang is just that little bit different to stop it from going back together again.

If you can see / measure any differences it would be good to know (for those who follow)
 
Well that's put my purchase for the month on hold! I am building up a supply of parts for doing the axle rebuilds and I was going to get a set of bearings etc for each corner, not cheap crap but proper jap bearings, but it looks like it will have to wait until I have striped them down first. FFS!

Also finding good quality bearings at the moment is not easy...

(Well for the earlier series 2a ones I need - not too sure about series 3 stuff)
 
The later half shafts are very expensive , what was wrong with your original stub shaft.
It was worn where the bearings go and the thread was buggered. Having said that if I had realised the compatibility problems I would have just bodged it back together anyway.
I have fitted new half shaft outer ends both sides as the old ones were really worn out but I was able to reuse one of the stub axles so does this mean that the side with the old stub won't work withthe new half shaft?
I haven't put the driven flange back on yet but so far I can't see the problem with the half shafts. What do I need to look out for?

Because of what's gone on here I would recommend stripping the lot, examine everything to see what is serviceable before ordering any parts. Even then get your supplier to confirm compatability. I've really been caught out by this and i'm still not sure that the parts I've got are correct.

In one way I'm fortunate as the only criteria I have for deciding on which parts to order is price. Cheapest only. This will no doubt come back to bite me in the arse at some point later. In fact it already has a little as they don't fit well and often need 'fettling'. But if I don't go cheap it will probably not get finished.
Never mind! I might win the lottery on Saturday and then it can have gold plated wheel nuts if it wants. Only gold plated though not solid gold. They'd be too soft and the wheels would fall off!
 
Today I have stripped and examined both rear hubs. The first bit of the thread on one of the stub axles is knackered but i'm going to do everything I can to repair it so I can at least be sure what bits where.
