shit, A+ CWP does not A series
Turbo Mini Forums

Hi Guys,

just at the stage of the gearbox build where i put the pinion gear on the main shaft and what do you know the bastard will not go on far enough due to its diameter.

does anyone know if anyone makes a 3.2:1 CWP to suit A series remote box?

i do not want to go to rod change as they suck.

if not i may have to go back to a 3.44 diff and use different drop gears to get 3.2:1

does anyone have a list of the different ratios available for the a series gearbox?

any thoughts guys?

I had the same even with an (early) A+ box.

It's the bearing retaining plate, they made the bore of it larger for the later boxes that had larger pinions.

Otherwise it's identical, I just sourced one from a late A+ box but you can simply bore the one you have out slightly (or even grind it carefully) until the pinion runs inside it without rubbing.

Schrödinger's cat - so which one am I ???

Rod is 100% right, get another retainer, or bore yours out.

I concur

You cannot get a different retainer, they're all the same.
You'll need to grind the one you have. Easy.

Thats where you are wrong Vegard

There is deffo a diferent retainer especialy for the 2.9 and 2.7 ratios

And I doubt Rover would have filed or ground out all post 1992 retainers just for the fun of fitting 3.1, 3.2 or 2.7 final drives

I doubt Rover were making many post 1992 remote change boxes

True, but I can't remember any other physical difference in the retainer plate between the remote and rod change boxes.....

The bearing it retains is certainly the same and, from memory, the little locking plate for the lay and reverse shafts (which is also located by the main retainer) is also the same ???

I may be wrong as I'm going by memory so if the remote box used a slightly different retainer, just machine the existing one out just like Leyland/Rover did later on anyway.

A picture and a thousand words and so on:

Forgive my thickness but is this the retainer?

If something is worth doing, it's worth doing half of.

there is not big problem to modify.
i have 2,9 diff on magic wand box and 1,3A+ block
i hope to find the photos to show.

I'm correct, you're wrong!

It's a good job that we all know there is more to life than being right all the time

Someone told me the other day.

He who makes no mistakes makes nothing!

If something is worth doing, it's worth doing half of.

How much weight difference is between them then?

I seriously doubt it!

Woopsy

Vegard, i'll be honest and say it matters not a jott to me My info came from Somerford Minis catalogue, and looking again you are indeed right.

Either way, you're right and im wrong

How do you get to become such a mind of information
