Your support is appreciated!
If you have a Defender/Tdi problem and do not know how to fix it, drop me a line!
Maybe I can help!?

I agree with discopete. The worm diameter increases in both side in such a way that the contact is maintained in all the angles
Something else I just learned after all these years, cheers Mike.
Thanks for this one Mike, still rebuilding my 90 onto its new chassis. Getting there but having problems with indicators and wipers. Will get there in the end. Keep them coming Mike, really informative and enjoyable vids.
Thanks, mike👍
I’ll show this to my MOT man! Every year he advises about play in the steering when there’s nothing at all in the straight ahead position😂
They should know this with a steering box - a rack and pinion is different
Thanks!
No problem!
Esoteric mechanical insights and marvels...
Excellent video ! Thanks very much
You are welcome!
Mine just failed MOT aim excessive movement in the steering. Trawled through your playlists and here it is. I’ll give this a try tomorrow. Good demo on the board as well. 👍🏻
This Malawi 110 leaks from the input seal - I was thinking of just buying a new box and sticking it on, but at £850 plus shipping - maybe not, so looks like another video in the near future!
Eye watering! I’ll look forward to the next instalment👍🏻
Brilliant!
Another question answered. Thanks Mike.
Quicker to do a small video than write an explanation!
Once again brilliant explication.
The worm gear doesn't have parallel sides, they are concave to allow for the contact with the wheel
I love how you class string as sophisticated equipment!! However I did notice it was red in colour, I hope it wasn't a Snap-on ball of string you are using or I may have to go back to watching Netflix!!
No it was regular string!
Great explanation. Can you do a full video on the steering death wobble and possible ways to sort it out.
I never had this with Defenders but a lot with Disco 1's - fortunately there are hardly any D1's here
Abosolute gold these vids. Very informative 👍
Glad you like them!
Hello
I am the owner of a Discovery 1 and a Jaguar MK10 with 420 power steering. I follow with very much interest your channel. But in the case of the Adwest power steering box play I could not fully agree. The steering worm is not from a constant diameter. The diameter varies. Minimum in the center and increasing to both sides, in such a way that the wheel in the steering arm maintains a constant distance with the worm gear. In adittion the gear ratio varies the steering id slower in the central position and faster in both sides. I wonder how the designers in the sixties could desing such a piece without any kind of CAD
...am I the only one who thought initially that the string was fluid piddling out of the back?
Built in leak!
Hi Mike.
Great videos by the way my drop arm has just started to leak fluid is there excess pressure buils up when on full lock
and is that the reason for the leak.
It was fine and i'm doing some restoration work on it (Disco 1 V8 ) so have to keep moving it in and out of the workshop.
The thing is it just started leaking today is this cause by pressure build up getting in and out of the workshop.
TIA Andy.
You should not hold the steering on full lock for more than a few seconds, but it seems the lower seal is in need of a replacement anyway
Hi Mike. When you adjust the nut, is it necessary to have the front wheels of the ground, jacked up?
Best with wheels up as you take the weight off the steering
So when there's there's a lot of slack in the straight ahead position movement on the steering wheel and the nut with the alan key is turned in as far as it goes with out it being forced down there is still slack does that mean it's too worn on the worm screw and a new box is now the only option
Could be - it would need stripping and maybe adjusting from scratch - the main selector shaft needs removing to set the worm - could be a bad bearing
yes, I have a Burman steering box that leaks.
My disco 2 has a lot of play in the steering. 210000 miles. You reckon adjustment make any difference or needs a new steering box?
Yes you should be able to adjust it out
hello I’ve got a quick question for you there’s movement in my steering wheel even though I’m not turning the corner is driving straight excessive movement would you say the steering box is no good excessive movement even when it’s parked up not running does the box need adjusting I’ve tried to adjust the box but it seems like it’s binding any help would be much appreciated thanks
You didn't mention what vehicle it is, but I would not recommend you adjusting the steering box without experience as you can make the problem worse - try to find a local independent shop to have a look - will not cost much, but better than the box locking up on the road!
Even us as the back of the class understood that
There are many who have come from regular rack and pinion steering systems to Land Rovers and are unaware that the boxes have this feature where rack and pinion does not have this issue
@@BritannicaRestorations Sorry Mike, my comment wasn't clear, it was a compliment to your simplicity in explaining.
Even I understood and I have always sat at the back of the class.
Q, what's happened to the Range Rover classic project Mike??? Is it still at the paint shop.....🤔
On the back burner - looking for parts for it - not easy!
I'd imagine that there would be more engagement points from the worm gear to shaft instead of just one,like a daisy with slotted petals? Are any other steering boxes retrofitable?
There are 3 teeth on the main shaft wheel
They are a strong box, but older ones are prone to leaks
@@BritannicaRestorations sounds a bit like an ex of mine...
Sorry I was getting confuse with a Gemmer box - the Adwest only has one tooth on the wheel/selector
@@gdritchie sounds like me a bit after an ex lol
I have a blog and it includes this page on rebuilding a Series steering box. The worm gear, main nut and rocker shaft arrangement are very similar to the Adwest box and it has the same play at each side, and is also susceptible to damage if adjusted offset. The photos of the internal parts may help your explanation. I think the play is specifically the main nut travelling along the slot of the rocker shaft fork at full lock, not the length of the nut from the rocker shaft axis (that length increase ought to decrease radial play if other factors weren’t present): www.nickslandrover.co.uk/steering-box/
The design of the series box is better in the fact that the recirculating ball cage has a locating pin which moves on the selector shaft /output slot, where as the Adwest is rather like an old worm and wheel gearbox - only due to the constraints of design, there are only one tooth on the selector 'wheel', so in extreme left and right positions the tooth contact is reduced, hence play, but the series should have no play in the same situation as the pin is allowed to move in the slot
Having problem with my steering get a cluck when turning right and goes turns it own way sometimes and gets wobbles is it my steering box have legit check over everything 10 times
So all the steering components are in good order and you still have problems? You could have the steering box overhauled, but I would have a competent mechanic check the steering, axle bushes, swivel balls etc. first.
Sounds like a poorly maintained vehicle
@@BritannicaRestorations yeah getting a steering box today and if that don’t work ima send it off a cliff lol replaced 2 tie rods yesterday wasn’t the problem
Those are expense boxes I heard
That's why I rebuild them
get one from a nissan patrol, or toyota 80 series.. nissan are stronger.. i have a l/rover box on my 75 ford f250 highboy.. couldnt find anything else at time. also have a box off a 280.?/.. mercedes.. you need to cut, weld drill..or go to a garage..
