Tuscan Throttle Moving With Clutch

[cammmy]

Hi All

Got my Tuscan last summer and been absolutely loving it but it's had one issue the whole time that I would like to sort.

The throttle pedal is moving with the clutch pedal. On the way down its not a problem as the cable stops it but when releasing the clutch, it brings the throttle up quite far and I have to take up the slack. Is there a stop that I'm missing, or is it a cable adjustment issue?

Attached are pictures as idle Vs after releasing the clutch

Cheers

Clean complete area, lubricate the shaft and bushes and check throttle cable and loud pedal zero adjustment
(There should be a little free play)
This should solve your problems

Awesome, thanks. Does lubrication require disassembly or is getting wd40 in there enough?

[cammmy]

I'm thinking my cable has stretched. I've taken everything out of it that I can at the engine end, Including winding the clevis on all the way down. It's better but still a bit of play at the pedal and the throttle return is basically coil bound at full throttle, which I'm not happy about. It seems that there's no adjustment for the cable at the pedal end?

Wd40 is good for cleaning, however for lubrication I would recommend an oil/grease.

PS: You are missing the cover in front of the compartment where the door ECU and dash ECU are located (to the right of the footwell)?

[cammmy]

Okay cool, thanks.

Yeah, it's missing the whole cover for the pedal box.

Judging by the rust on the pedal box I'd guess the smaller rear pivot bar has rusted and/or bent, meaning the rocker levers are sticking on it. You'd be best off taking it out and rebuilding it with a new stainless bar.

Nice one, thanks. I'll look that.

Spoke to racetech and as you say, they suggested the bar rather than the cable. They said that they have the bar in stock but they are waiting on a supplier for the bushes with no ETA. They suggested I could try cleaning it up but there's a risk of breaking the bushes on disassembly. I may just have to order and wait.

I've just re-done mine and both the main alloy bar and the small one were corroded, plus the smaller one was bent as it's a bit thin for the forces it has to deal with from the brake pedal. I replaced both with stainless.

Nice one. Did you disconnected the clutch and brake master from the box and leave them in place?

Any tips for getting the pedals apart or is it straight forward? I have the Graham Varley Sagaris manual but it doesn't seem to have anything in there about getting the pedal box apart.

Yes, disconnected and left in place. The 2 bolts through the clutch master are a bit fiddly but brake ones are captive studs.

The pivot bars slide through and just have circlips on each end to hold them in. I had to tap mine out gently as the corrosion meant they wouldn't slide. It's not complicated but worth taking pics so you know which spacers go where, as not all the same size.

Cool, thanks. Will do. Hopefully the supplier doesn't take to long to make the bushes.

Did any of the bushes break when you did yours? I'm contemplating whether to have a go at getting it apart to clean it up as a stop gap, but not if the risk it too high. I have a press, that might be less likely to break them than a pin punch/hammer?

[Basil Brush]

As long as you are careful you should be OK. If you try and remove the nylon bushes from the pedals and rockers you may break a few, especially the small ones, but you could clean/replace the shafts and leave the bushes in place.

Nice one, thanks. Not looking to remove those currently.
