101 Power Steering

[101RRS]

Other than the red 101 camper does anyone have power steering on their 101.

In the UK they use a box out of some old Brit van or a RRC/Disco 1 box but both require cutting into the front chassis rail which I am not keen on.

I have heard that a P38 box will also go but have not heard anything about that mod. I have also heard a Patrol box works but again I do not know anyone has done it.

Likewise with power steering on the red 101 camper which was done by AJ in Melbourne no one seems to know what system it has on it.

I have not problems steering the 101 on the road or offroad but in tight manoeuvring it needs to be moving slightly forward or back to turn the wheel. The strength is there but the shoulder ball sockets are no up to it.

So if your 101 or you know of a 101 with power steering can you post up the system in use and what mods to the front end are required.

Thanks

I was talking to AJ about this some months ago. There was another type that clamped on. Might be worth giving him a call to find out what solutions he has.

Yes there are the old ram types that bolt onto the steering rods like 60s Holdens and some series landies have them but they do not work all that well and I would prefer a steering box type unit.

The one I saw on one of AJs was off a Mazda IIRC. The box mounts to a new cross member mounted between the chassis side rails forward of the OEM front member on an angle more forward on the RHS and touching the front cross member on the LHS.

I'm thinking the steering lever on the bottom protruded to the rear with the tie rod end in line with the original track rod.

A bevel box is fitted below the original steering column to re direct the rotary motion from the inclined vertical axis to a lateral axis aligning with the input shaft of the PAS box.

The bevel box (usually sourced from a forward control van like a Mitsi L300 or Delica) needs to be modified to reverse the direction of rotation, this is usually achieved by moving the input bevel gear from driving the top of the output bevel gear, to the input gear driving the bottom of the output bevel gear. The actual process requires removing the input gear from the input shaft, the gear turned over and refitted to a lengthened shaft.

A P38a box would fit in position the same as the mazda box, alternative the PAS box off some Toyota Land Cruiser is the same orientation. What is more, a friend recently fitted a Toyota LC box to a non-PAS FJ40, they fitted it up only to find the box turned the wrong direction. They solved the problem by getting an alternative LC box that turned the correct direction. This means that by finding the correct LC box you wont have to modify the bevel box.

On the day I saw AJs 101, he had just picked up a bevel box off some sort of armoured vehicle which he thought would be much stronger in place of the van one. It may well have been the gear box off the turret traverse mechanism.

Thanks Diana - never heard of that one before - sounds a bit Heath Robinson - very British in thinking even though it uses Jap parts.

I must admit I was thinking about going around all the light truck dealers and if I can find any light truck wreckers and climb under their forward controls to see if there any ideas there.

Hi Garry

Its rather simple actually, the new cross member was merely some heavy angle iron.

If you could find the bevel box off the armoured vehicle it mounts under the floor where the OEM steering box sits, it may even poke through the floor.

The output shaft then points in the correct angle towards the PAS box and then just find the LC box that turns the correct way. The rest is making a new shorter drag link and connecting up all the shafts.

The ram type system is very good if done right.
Vickers were the main manufacture of this type of set up in Australia.
I can still find Australian manufactured forklifts with 2 tonnes of counterweight sitting over the steering axle and you can spin the steering wheel around lock to lock without moving the vehicle forwards.
I dont think Vicker exist, or make these steering set ups anymore.
Vickers steering rams are still repaired by most hydraulic specialist workshops.
The main thing which must be done to fit as a ram anchor ball joint point on the chassis inline with the cross chassis drag link.
the vickers ram shaft will need the correct sort of adaptor to fit on to the original drag link or LHS CV joint housing.
The Ram must have the correct tappered pin or adaptor from the cross chassis bell crank to tigger the rams valving..
The above set up will work as hard or as little as you like, it is all about hydraulic pressure from the pump.
The above will require little as possible modification of the vehicle.
It believe the Red 101 which AJ done is one of Two he done and use the Nissan steering box.
I have seen a 101 done with a Disco steering box which used a Disc steering wheel and columb and I have driven this vehicle, it worked well and I
do have pics some where.
The disc mod had the steering box and columb offset slightly from its central positon in the middle of the floor.
I have been looking at the vickers type set up, but have not come across a suitable ram at work.......the whole steering thing has not been a issuse with me as I just eat my spinage.
Garry I f you are getting to old to drive your 101 I can find a good home for it.

This is what I did with the 6x6. Though may not suit your application.
4 bolt box on its side. Works very well.

Thanks - on a 101 the 4 bolt can go in - I have detailed instructions on how to do it but as mentioned above it does require cutting into the front chassis section Grumble PAS Conversion

Thanks also Diana - I assume your description is how AJ did Alan's (????) 101 camper.

Ron, I assume the 101 you are talking about with the Disco box is the white 101 with Toyota running gear.

Anyway -I take it that other than the red camper and Rons mysterious 101 no one has or come across a local 101 with power steering - in particular one with a P38 steering box - any one with a P38 want to pull their steering box out and see it if will fit with minimal modification to the chassis .
