101" special wheel nuts for front step

[Lotz-A-Landies]

Just a question out of interest (and something I have).

What thread are the wheel studs on the 101"?

Are they the same M16 thread as the Range Rover classic and Series III Land Rover or something else?

(I have 5 wheel nut/step studs which don't fit either the 9/16" BSF SIIB studs or the Stage 1 studs and wonder what they are off.)

101 wheel nut part number is 90577473 and is not a unique 101 part - so I guess it is the same as a series 3.

The nut for the front wheel step is part number 592926 and the book does indicate it is unique to 101s (at least in 1977). I assume you appreciate the normal wheel nuts bolt onto the special step nut to hold the actual step on.

I know you have part numbers for everything so from this you should be able to work out the specific answer to the question which is most like yes - the actual nut thread is the same.

No I don't have an SIII book (or any book for that matter) at work so will have to check later when I'm home.

If I had known that the 101" used standard Range Rover classic/Series III wheel nuts then I wouldn't have had special nuts machined up. I could have gone out and bought some off a 101" :( ( damn )

Regarding the other 101" nuts, if the nuts for the step are anything like the ones for the SIIB it will be because they are flat both sides. I'll be using standard RRc wheel nuts, of which I have a heap.

So that now leaves me with a quandry, "what are these special nuts that are too big for the SII hubs and the wrong thread for the SIII/Stage I/101"? :confused:

The outside of a 101 wheel nut fits a disco wheel brace perfectly - just tried it. A series I wheel nut thread is too small but I did find another landie wheel nut lying around - its outside is the same as a landie 101 or disco but the thread is too small and is in fact the same as a series 1. Now I am all confused because I have about 50 disco wheel nuts somewhere and cannot find any of them and that will give the answer.

My 101 books do not list the specs of the nuts or studs except the standard nuts and studs are not unique to the 101 and came from other landy models in service in the mid 70s.

The step nuts are unique but they obviously screw onto the wheel studs and normal 101 wheel nuts screw onto them.

Don't get very confused about that. At the very end of series IIa there were 109" Land Rovers with exactly the wheel nuts you are talking about. The same 27mm socket as the Range Rover classic Disco series 1 wheelnuts (or it's AF equivalent) but 9/16" BSF thread.

If you are willing to part with it, a friend is looking for some. What's a wheel nut worth????

Ford and Chev Blitz are 5/8 UNF and 15/16 socket, while Morris-Commercial (also 25pdr and Bofors guns!) are 5/8 BSF and 15/16 socket. Both types come in Left and Right threads. A possibility?

5/8" BSF sounds like a possibility, but do they have a wheel nut with a stud at the other end?

So - ur after my nuts:eek:

Well the one I think you are after does fit Series 1 studs (whatever thread they are) but the outside hexagon fits a Disco 1 wheel brace. If you want it send me a PM with an address and I will send it off - gratis - free - zip

I can supply BSF taps in 9/16" & 5/8", both right and left hand. Do not have any BSF dies over 1/2". Can supply NF taps and dies in both sizes and both hands.

That raises some interesting possibilities - do you know what the is thread on Series 1 & 2 steering tie rod ends. ???? 5/8" and could they be used to make up a track rod for one of my SIIBs?

Regarding the special wheel nut/step thingo, I have enough specially made ones for my hybrid front axle, and thought that I had enough for the regular SIIB front ends. Unfortunately now that I find that 5 of the 12 needed for the 2 vehicles are 5/8 or larger, so I probably need a couple of 9/16" ones. If I can't find some at any of the usual suspects, I may have to have them made also.

No, I don't know. Get a cheap plastic vernier caliper that reads in fractions, and a set of screw pitch gauges and measure them. Tie rod ends are commonly 11/16". Most later LR's, & RR's, have 11/16" 16tpi LH & RH tie rod ends. 11/16" x20 are sometimes seen on other vehicles and 11/16" x 18tpi were used on GM & Ford vehicles & others for decades. Steering rods are easy to make.

Thanks Brian

I have a good quality Vernier (tool steel) and sets of metric and imperial pitch gauges but have never bothered to measure a tie rod.

My reluctance is the cost of a 11/16" LH thread tap (I probably have an 11/16" RH BSF tap) when it will only ever make up two steering rods.
