Suttons Posted January 14 Share Posted January 14 Hi all this is my first post on the forum, I’m looking for a bit of advice. I was looking forward to taking out my caterham 140 supersport today, and when I started the car it was revving really high. I looked under the hood and traced the accelerator cable to the return spring which seems a bit stiff, so not sure if they need replacing or if there is another issue.

Member Jonathan Kay Posted January 14 Member Share Posted January 14 (edited) Welcome I suggest starting by checking exactly which bit is sticking. Disconnect the cable at the throttle end and at the pedal and then see which parts move smoothly and which don't.

Area Representative Golf Juliet Tango Posted January 14 Area Representative Share Posted January 14 (edited) Wecome Common reasons for this in my experience (some may not apply your car): the cable rusting or with ice crystals inside the Bowden cable the pivot bolt tightening up You shouldn't need an assembly guide to sort this out but they are online and downloadable here:https://caterham.dk/Assembly_Guides/index.htm Edited January 14 by Golf Juliet Tango Link to comment Share on other sites More sharing options...
Suttons Posted January 14 Author Share Posted January 14 Hey all thanks for all the replies and help, I’ve managed to fix the issue now. The problem was the pivot bolt being too tight. Is it common issue for it to self tighten over time? Link to comment Share on other sites More sharing options...
7 wonders of the world Posted January 14 Share Posted January 14 No, if the shaft was lightly greased on assembly and a little clearance left as the nyloc nut is fitted all should be well. Link to comment Share on other sites More sharing options...

Not sure this is correct. In my experience the accelerator pedal is held by a bolt into a captivated nut in the chassis. There is a bush in the bracket upon which the pedal rotates. Bush enables the bolt to be fully tightened without pinching the pedal. I’d suggest dismantling and cleaning then applying a little copper grease before reassembly.

Mine bolts into a bush on the spaceframe. Just as Paul has also posted. I suppose if it is/was a persistent one might use a threaded rod and a nyloc on the outside end.
