Yes, its because the speedo drive is at the bottom that is causing me concern, I want to get this right before the engine is installed. You say "it locates on the very fine brass threads of the speedodrive." Could you be more specific please, what locates on the fine threads {1/2" X 26tpi}, the cable or the seal? Do you have to dismantle the drive mechanism to access the seal ring? Or can you get to it from outside ,? Is it behind the part with the slot in it that drives the cable? I didnt really want to take the mechanism off now that its all sealed up with a new gasket but I will if I have to.

Is this the early one? see pic.

The speedo cable fixes on to the fine brass threads of the drive unit.  The seal is behind the slot where the drive fork locatates.  Put some oil into the gearbox now before you install it and check but it will be oil tight. Your are worrying about nothing, honest. 

The speedo in the picture is the early type but is not the specifc one I was thinking of for your car.  It should have a black face, 80mph (yeh really !) and the needle rotates in a clockwise direction.

Hi
If its any use, the Frisky 9E uses a Clockwise speedo  Smiths 2.5 inch dial   Clockwise sweep 10  to 80 MPH
 Dial info   is   SN3103/71   1530

The 3T also uses the  identical speedo. Ray has tried one of my anti clockwise speedo and confirms it didn't work on his 3T FriskySport

Hope this helps (I realise I'm playing with the big boys here!!)

What, you mean if I use this speedo my car will only do 60mph instead of 80?  :D

I may be waisting my time with this speedo then as it comes from a AC acedies with an 11e that has an add on cog driven speedo drive which I guess reverses the rotation. Now I'm thinking if I link this one up it will be turning the wrong way. Hmm, will try it out tomorrow.

Oh dear! My fears are realised. My speedo works the opposite way around to that of my drive. Grant is right, I now need one of those black dialed 80mph speedo's. One with a clockwise needle rotation. Does anyone have one for sale?  At the same time does anyone need a speedo from an AC Acedes IC? I also have the drive mechanism to match.

Do they run anticlockwise then?

Number is SN 3177/00    1216

I'm willing to swap with something suitable.

some do some don't with the early bonds. the 1216 is rpm so wheel size is the issue i guess . don't know what all the other numbers can signify - but some sad old codger will  :D stuart ? grant ? are you there ?  ;D

will get back to you bob

Yes, still here.  Not 100% sure on this one.  The number refers to Smiths specification and the ratio. However, since the speedometer is driven from the gearbox and not the road wheel then should the wheel diameter be an factor ?.  It is on a Bond which drives the speedo from either of the back wheels so there has to be a difference between those with 8" and 10" wheels. However on a Frisky, Scootacar, Tourette and IC all fitted with a Villiers 9E with gearbox speedo drive then will they have all the same speedometer ? despite having either 8 or 10" wheels.

this all emphasises the difficulties with RUM cars, rather than isetta, messerschmitt , treinkel etc , nothing seems set in stone . johns leads look likely though one would break your budget .
see attached a letter where nick mander was explaining same to me re Bond A speedo driven by a mamod type wire running on the front hub !

I guess not. The IC  has the 11e with gearbox that doesnt have the speedo drive sunk into the underside of its caseing. It runs off of a seperate transmission box, so what with this and the bigger wheels I think the waters are too mudded to work out the ratio's unless someone has knowledge of what the numbers mean.

Thanks John. I did spot these but at this stage I just dont know if a ratio of 2:1 is what I require. More research I think.

I'm told that the last four digit number on the dial indicates the revolutions per mile. Can a scootacar owner out there please tell me what the last four digit numbers is on there speedo please, then I will know what I'm looking out for. CHeers.

are they all 10" wheels ?including bobs . i did say rpm which i meant as that .

tha  Bond A has a much more realistic instrument  ;D interestingly having 2000 rather than the apparently correct 1800 ( 8" wheels ) as the figure but again it's just the one that looks the part that i found - a moped or the like probably, it has that little mounting bracket on the side , but that will go .

obviously wheel size must be important if 2 vehicles both ran on the same gearbox drive but one car had wheels twice the diameter a totally different speed would be recorded in each car . WHEELSIZE is important - or sprocket hmmmm
