*HOW TO* Convert F20 to Cable Shift - F17 Turret (Morse Cable Bulk Buy)
*HOW TO* Convert F20 to Cable Shift - F17 Turret (Morse Cable Bulk Buy)
This is a ‘How to guide’ for fitting a Vectra C 1.8 F17 Gearbox turret to an F20 gearbox fitted to 1991 Nova Trip and converting it to cable shift.
I also want to arrange a bulk buy for the cables required to fit all the parts to the car. More info on ‘Morse Cables’ in the thread.
Parts Required
F17 Gearbox Turret and Cable Mounting Bracket (good idea to take the Vectra cables although they are too long for the nova they may fit other cars)
Vectra C Gear Selector (pretty sure any selector will do from any cable shift car, the Astra VXR or H has a shorter throw so I’m told as well)
Shifter Cables
Push-Pull Cables
This is a summary of info regarding shifter cables which I’ve gathered over the last while and its probably the most important part of getting the setup to work in the car.
The shifter cables in the Vectra are known as Push-Pull. Identical cables can be found on boat throttle cables. Most commonly know as Teleflex Morse Cables, normally 33C Teleflex. The Teleflex 33C cables are terminated in ‘Clamp’ ends, usable but better with bulkhead fittings on a car. So 33B is for bulkhead. The inner cable ends are normally 10/32unf.
The Vectra ones are 30 series cable with 65mm/85mm Travel.
and similar ones can be bought from most marine outlets, unfortunately the shortest length readily available is 4 feet, which is around the length of the Vectra ones which are too long. Nightmare!!! Custom ones it is then… (bear in mind this is on a nova, Astra / Corsa main differ)
NB - These are heavier duty than the standard Vectra ones and will be fit for more abuse.
The only thing left to buy is M6 to 10mm ball joints to tie into the turret and selector (the F17 turret has 10mm ball joints on it)
Please PM me if you are interested. You will need to mock up a length and tell me.
Pics to follow and I’ll put up more info / pics of the fitted cables once I fit mine. I'll put a pic up of where my shifter is on my nova and if your happy to put yours in the same position then you can get the same length cables as me.
