very old RR 4 speed box into 110

Have a problem. Got a 1975 RR engine and gearbox but the box won't
fit my 1984 110 according to the mechanic. It's the same box and
transfer (albeit with different output gearing) but the problem is the
handbrake. Even by swapping my linkage over to the replacement box it
has been found that the older box has a smaller handbrake drum which
is a push linkage rather than a pull, according to my mechanic, as
well as being in the wrong place with regards to the 110 handbrake
location in the cab. Currently, he can see no way to fit the
handbrake so I'm left with a bill for him removing and now refitting
my original box to the new engine.

Does anyone know of a solution to this dilemma please?

It isn't rocket science and any half decent mechanic can knock together
a linkage that will work. ISTR the handbrake operating in a strange way
when we put one in a Lightweight a few years ago. The solution was to
place the handbrake lever between the front seats (no centre seat) and
use a cable to operate it. To turn a pull into a push just needs a lever
connecting to the handbrake actuator that has a central pivot. The
handbrake cable then connects to the lever on teh other side of the
pivot point.

On the lightweight it took us about an hour to make the lever and get
the brake working. We used a Range Rover handbrake lever.

If yout mechanic still claims it can't be done I suggest you get him to
finish the job without a hand brake then you can take it to someone more
competent.

can you not swap the handbrake drum etc over from one t-box to the other?

My mechanic suggested that but said that would involve removing the
end of the transfer box which would mess up the preload somewhere?

dunno, but I doubt it. The drum is on the rear output shaft, the backplate
bolts onto the casing somehow. I've never actually pulled one off. I
expect the book has something to say on the subject.

Putting a RR autobox into a 110 had interesting results for the handbrake -
both are cable operated but the old 110 LT77/LT230 had a completely
different mechanism. Even getting the parts for the ZF/Borg Warner setup
didn't result in being able to connect the cable meaningfully, so I ended up
inventing a gadget to do it involving several lumps of metal.

Your mechanic is right.

There is a shim which determines the bearing load on the centre diff. I don't
see that this could be replaced easily with the box in situ, although it might
be thee most satisfactory approach overall.

Just had a glance through the HBOL which doesn't make any mention of that in
removing/refitting the handbrake. You do have to get the driving flange off
the end of the shaft to get the brake backplate off, but it looks
straightforward enough. It's possible that the HBOL is talking bollox, but
I reckon that it should be possible to swap the brakes over from one box to
the other without difficulty.

Sorry, I thought tthe suggestion was to swap the entire back half of the
transfer box.

Simply replacing brake components wouldn't cause this problem

well, it *sounds* like that's all that is needed. Maybe the larger brake
won't fit the early box, though, without swapping ends. But unless I'd
tried, I wouldn't know for sure. and modifying the brakeplate would be
easier than most mods.
