Differential Questions

[Sienna PI]

Hi All!
I have just had new bearings and seals fitted to the Input axles on my diff' - after bolting them back into the unit I have noticed that there is a gap between the bearing retainer and the "cup" on the end of the flange on both sides (approx 2mm on offside and about 5mm on nearside)...
i)  should there be a gap here?
ii) or should the cup fully cover the bearing retainer?
iii)the gap is larger on the nearside - should they have the same gap either side?
Cheers, Sienna PI.

Its mebe just the seal aint pushed as far back as it could be.
Or, mebe, the two halfs have no been shuvved onto the taper enough,
or tightenend up enough to get em back on.
you tried tightening the bigg nut, if this is tight, then its no gonna budge.

Butt,as long as its on the smooth bit, then it will seal

Is the cup welded or an interference fit to the output shaft?

Try measuring the distace from the flange to cup. They may not be in the same position.... :-/

or is it bent moer on one side than t,other

Hi!
Thanks very much for your responses - Yes I have tightened the castle nuts tight and am thinking that they have not  pressed the new bearings etc. on fully by the garage I took them to. Here is a photo of the nearside.

And here is the offside.

that looks like the oil seals are no in farr enuff
just went,n took some pics for ye.

the oil seal is at a jaunty angle, so as its right doon on ya side,
an a bit off ont t,other side

AND, maybe, but its a bigg maybe,  the bearing has no been pushed  on farr enuff,
or the  hub bit, no gone onto spline/ taper enuff.

pics are a bitt iffy, but shows ye what im on aboot.

{ Ohh for any one woe can get 3 d images,
the paper goes  3 d when ye look at it,,
does me heed in at times, a most weird experiance seeing
me kitch in 3 d !!!!! }

As M says .. Something's not right there either the bearing or the oil seal .

Here  ye go Sienna, some better pics, an a explanation as to why yers are like they are.

with woodruff key at outer end like so





and  it will sit like this,  its still loose, so will move doon a wee bit
wen tightened up ont bigg nut



Not ont inner end,like this




If key is at bottom end nearest diff, it will sit like this



keyway int shaft, bearing reet in too



with oil seal in spot



So, it looks like the actuall key is too far doon the slot
this stops the hub bit frae gaa,n doon  to sit correctly

hope this helps ye oot

Hi!
Many,many thanks to all your responses especially GT6 M -your photos are invaluable and made it quite clear for me.
I rang the garage today (that pressed on the new bearings etc) and they are happy for me to take the Diff' to them to check the problem (Fingers crossed!) 8)
Cheers!
