Throttle cable

I expected this to be a nice quick job but it proved far from the case and as I type it is not fully resolved...bear with me and I can explain..

The throttle cable needs some "customisation" to fit to the air intake butterfly valve. If you proceed to fit the cable straight off the shelf, when connected up, throttle travel opens the valve no more than 10% of its full required throw.

So...first piece of customisation... the plastic end connector needs approx 2cm removing off the threaded end and on the piece which screws onto the threaded end that also needs trimming back - hope the pictures below explain that more clearly...


The smaller "pyramid" shaped piece then clips into the butterfly valve frame:


The above customization provides sufficient throttle throw and fully opens the butterfly value.

The throttle cable routing is the next puzzlement...running down the outside chassis rails whilst trying to avoid contact with suspension mounts / steering column is a challenge and although I have routed it I am not happy with how it currently sits...There seems too much cable for the distance it needs to run from the pedal box to the butterfly valve.

So a frustrating session on the build, whilst i have got full throttle travel I am not happy with the cable routing... I am now starting to wonder if I have the RHD Throttle assembly - have I been given the LHD in error? is there a difference between LHD and RHD throttle cables even? - I need a chat with GBS to resolve.

Pedalbox

Whilst the scuttle is in position I had a look at the pedalbox since fundamentally it looks straightforward to fit and with little work required to be done.

To complete it, so to speak, it needs 10 M8 rivnuts fitting, and simply positioning screwing into place on the chassis, firewall.

first challenge and one which I had noted on other builds - the throttle pedal screw on initial fit does not fit straight into the locating hole in chassis - very puzzling.... 


Solution is quite straightforward and a light bulb moment sat in bed drew me to the folds in the pedalbox base where it folds out to lay flat on the chassis. Simply put, the folds need tightening - so taking a toffee hammer to the fold and using a straight edge (steel rule) - tap along each fold line to tighten the fold to a defined right angle. place back in position on the chassis, push the throttle bolt through the pedal box into the chassis frame and bingo it goes in straight - result!



The box will need some selective trimming and bending dependent on respective fit to firewall and chassis but overall as mentioned earlier this is a nice quick job to do.

M8 rivnuts applied to the top edge of the box where the lid fixes in position and also along the bottom edge into the chassis frame (be careful, these holes are quite close to the edge of the chassis frame). Finally a couple of further holes to secure into the firewall and job done its fitted.
