HI I am running the Edlebrock webber 500, you have to get this right or you will damage box, thanks for contact

Hi Terry
i cannot see how the kickdown cable would damage gearbox as otherwise damage would happen if you manually change down the gears with the shifter. As the two are linked via a shaft. Maybe Chris Spain will be able to help with the Webber set up.
There is a problem with the steel seals on the input shaft that if revved past 2000 rpm in park it could cause the seals to fail and allow the front clutch to burn out. Their are now Teflon replacement seals.
I would point to to www.jpat.co.uk look at their catalog page then zf lots of pictures of zf. I also believe they might have the kickdown measurements on there for the different cars.

Cheers Glenn

HI Glen, as I understand it the kickdown cable has to be fitted correctly and the right ratios to throttle as the gear box then knows how hard you are accelerating, without this info the clutch packs would stay loose and burn out,this will not happen instantly but over a period of time.and of course it does the change down.hope I explained It ok.

I think this is a slight misunderstanding of the way an automatic gearbox works. The brake bands rely on oil pressure generated by the rotating pump at the (usually) front of the gearbox, and are controlled by the internal governor to change up and down at speeds and loads set by the internal adjustments (in the case of the BW 'boxes, sprung valves) at the time the gearbox is specified for a particular installation.

The kickdown cable adjusts the changeup points depending on the throttle opening so that, in general, the change up occurs at higher revs (i.e.more power) with the 'pedal to the metal' than on gentle throttle.

This doesn't answer your question about the coupling of the kickdown cable to the Weber carburetter, mine is Strombergs like the pictures above.

The cable should be installed with approx 1 - 2mm slack with the throttle closed and kickdown indent should be set to just before full throttle. As for the size of the quadrant you need, you will need to determine that with your carb set up. I have mine set to select 4th gear at approx 40ish MPH on a very light throttle
You are almost correct when you say that you can damage the gearbox. however you will only damage the gearbox if you run the box without the cable working for prolonged periods.
Hope this helps.

Les.

Please can you let me know what changes you had to make to the bell housing etc. I love my automatic Stag but I have to admit now that I wear hearing aids, the noise level at 70mph is perhaps a little more than I would prefer. I am half looking for a 4speed ZF box for as and when my BW65 says it has done enough. So any knowledge around what is involved is knowledge worth storing up. The car for now runs on twin Strombergs. They do tend to make a smell when the car returns to the garage after a run. I usually vent the garage for an hour or so so as the smell of petrol does not invade the whole house.
Look forward to your reports as to the reduced noise levels and improved MPG.
Cheers

HI Nigal ,sorry I cant tell you how to modify your bell housing, My engine is a Rover v8 so the gearbox and bell housing from a Range Rover bolt straght on, sorry I cant help.

Smell?? It's like perfume - the best air freshener I've ever come across

The ZF kit comes with a new convertor housing to suit.

The overall effect is to reduce the engine speed lots:- approx 2800rpm = approx 75 mph iirc. (my speedo isnt very accurate, i'd need to check against sat nav for more accurate numbers)

The T&L ZF kit is comprehensive, only thing it does not include is labour and transmission oil.

The BW boxes are becoming more difficult to get parts for now.
