Anyone know if the later type (Burman) steering boxes fitted to 2200cc
Rover P6s are a direct swap for the earlier type?
I was about to swap the one on my 1972 2000TC for one I'd bought off
eBay when I realised that they look rather different. The manual
identifies my eBay bargain as the later type, but doesn't say whether
it'll still fit. I'd rather not remove the worn one until I'm sure of a
replacement.

Chances are that it is. Later s/boxes are usually made to fit the
original cars, rather than modifying the cars to fit later boxes.

That certainly goes for the SD1. AFAIK they fitted a manual box,
and 3 different power s/boxes. Burman, Alford & Alder, and Cam
Gears. All used the same mounting points, and were
interchangeable.

What does vary though, are the pumps and mountings. The SD1 had
different pumps according to which box was fitted. I don't know
if they are interchangeable on the P6, I suspect not, so you may
need to source an appropriate pump with it's mountings.

Should be easy enough to check, by measuring the mounting points
in relation to the column shaft and ends of the rack, and
comparing them with the one fitted.

Thanks Mike, that makes sense.

It's manual steering, so at least that's not an issue.

Trouble is, the wiper rack has to come out before the inner mounts can
be seen properly, and that means removing the top panel first. Neither
are especially difficult, but it all adds time. And I could still find
that the column has a different number of splines or is a different
length...

I've only decided to do this now, because the engine's out of the way.
While it'd be nice to sort out a few problems while it's convenient, I
don't want it to drag on for too long.

I do have a "spares" car with the older type box in good nick, but still
haven't decided whether to break that one or fit a diesel engine as
discussed a few months back. I do know that if I start removing parts
from that one, I'll never get it back on the road.

None of the four cylinder models had power steering - much though they
needed it. The V-8s had lower geared steering and power wasn't even an
option 'till about half way through the model run. Men were obviously men
in those days.

As regards the SD1 racks some had specialised mountings made specifically
for the rack - so were only interchangeable if you had those. Which
sometimes you don't if buying an exchange one.

Trivia

Thats the "plenum chamber" cover, interesting meaning.

plenum - an enclosed space in which the air pressure is higher than
outside enclosure

or a structure consisting of an area that has been enclosed for some
purpose.

A lot of terms have now been lost and new ones have taken there place
especially in the rubbers and felt bits spare parts.

Just an thought.

Yup. IIRC the Alford & Alder box had bent MS straps holding the
rack whereas the Cam Gears one had cast ally blocks, but it was a
long time ago when I changed from one to tother, so I may be
wrong.
Same mounting points though.

AFAIR I have a manual steering rack for an SD1. Any idea if it's
worth
anything?

They're about 50 quid exchange for a recon one from Rimmers if that helps.
Suppose someone racing one might want manual steering - but I doubt any
would for road use.

Cheers Dave. Well I won't chuck it straightaway, so if you hear
of someone who wants it, they can pick it up for nothing,
(Horsham W Sussex area) or the cost of P&P.
Mike.

For anyone interested, I can happily confirm that the later type
steering box (from 2.2 litre cars) _is_ a direct replacement for the
earlier type (from 2.0 litre cars).
Swapping them was a little involved, but nothing too difficult. The
wiper rack has to come out first, which means removing the plenum cover
(thanks Rob!). I find it easier to remove the bonnet too so that the
rack can be twisted 180degrees to lift out.
The brake fluid reservoir has to be moved because it bolts to the old
steering box, but can't be bolted to the new one. I moved the coil to
the front of the brake servo (the mounting holes line up perfectly) then
made a bracket to mount the fluid reservoir where the coil had been.
This is close enough to its old position not to effect the pipework.

A helper is needed when lining up the splined input with the steering
column UJ. And then again when you have to do it a second time after
finding that one of the mounting bolts won't fit and has to be replaced
by a stud and nut!
