A30/35 propshaft

Post by TStanb »

Hi
I've been kindly given an A30/35 propshaft for my smooth case remote 948 gearbox.
I only need the front coupling and U/J, however it appears the MM gearbox output shaft is wider than the "female" A30/35 coupling on the propshaft.
Is this correct or is it me not lining up the splines properly (this has happened with me on other vehicles before)?
Thanks

Before you do anything make sure that the prop shaft is of the correct length.

Why does the length matter if he's only using the front section?
I can't see that the front section of the Austin wouldn't be of use on a Minor myself.

Yes it will be cut and shut anyway because it is going into a special.
I suppose what I am saying is...does an A30/35 propshaft fit onto a smooth remote MM box?
Does the gearbox's drive spigot's splines correspond with the propshaft's splines?
thanks

Yes. MM and A35 gearbox are the same.

Only difference is the series 2 MM and A30 boxes. MM has a slightly shorter tail shaft.

Thanks.
It WAS me being incompetent, then...It hurts but that's much cheaper than having to buy a propshaft

I removed the u/j from the front and it fitted easily.

HOWEVER, once cleaned, greased and reassembled, it (the u/j) does not move quite as easily as it did before I took it apart.

QUESTION... if one of the needle rollers fell over into the end of the cup during reassembly, would the u/j still move and operate? Or would it seize solid or be VERY stiff?
