Hi,
Last year i swapped the gearbox on my hill climb Puma for a ford racing puma box. I also swapped the clutch from the same source which was a relatively new clutch.
Since then the biting pint has felt quite high and today i notice that the front wheel were spinning quite fast, with some force, when the engine was running but the car was in neutral. I couldnt easily stop the wheel spinning but when i did the revs died and the idle dropped almost as if the car was going to stall.
Clearly i've done something wrong. Any ideas?
I guess its box back off tomorrow. Am i likely to need a new clutch too?

Well if you think there is an issue with the engine running, wheels in the air, in neutral and foot nowhere near the clutch pedal...Last year i swapped the gearbox on my hill climb Puma for a ford racing puma box. I also swapped the clutch from the same source which was a relatively new clutch.

It has nothing to do with the clutch. Because the clutch is fully engaged at that point and the input shaft is being driven.
That's more indicative of a gearbox problem. Unless you're describing things wrong.

From what you describe then yes the clutch is engaged. It would only be disengaged if you had your foot on the clutch pedal.So, as has been said, the issue is inside the gearbox.
Does the gearbox have the right type and quantity of oil?

Ok, interesting.The only part i left out was the car was in the air as i was changing the oil. But i see what you mean-the imput shaft if somehow transmitting drive.

As I said, and as Steve said, of course the clutch is engaged, your foot was not on the pedal to disengage it.I was thinking the clutch is somehow engaging?
Ok, appologies, just my lack of understanding. I'm a panel beater not a mechanic, sometimes its a case of a little bit of knowledge being a bad thing.
I've been to my workshop again this morning and tried it again. With the engine running and wheels in the air the wheels spin quite fast. When i apply the foot brake there is a clunk from the gearbox.
So yes, it could be incorrect oil in the box i suppose. I refilled it with raceline oil which was supplied as suitable for an Ib5 gearbox.
I dont have time at the moment but i'm going to do my first event and after that swap the box to a spare i have

Its perfectly normal.
All of the fiestas do it when you lift the front wheels off the ground with the engine running.
Most cars do it to some extent, it is called clutch drag. It can, however, cause additional problems like difficulty engaging gears at standstill, particularly reverse.All of the fiestas do it when you lift the front wheels off the ground with the engine running.
You can google it & it should really be sorted out.

THE CLUTCH PEDAL IS NOT PRESSED. The clutch is fully engaged.
It is entirely drag within the gearbox, nothing to do with the clutch.
As i said, im not a errr...natural mechanic! I've been rebuilding my Mk1 golf after two years of bodywork and i've done most things 2 or 3 times...generally as i hadnt done it right the first time
So lest just say the clutch plate is the wrong way round, its already done 700 miles and 5 hillclimbs. I need the car for a test day on the second of next month but as i've just handed my notice in to go self employed i'm quite busy at the moment.
Do i risk it and run the car for the test and then the first event two weeks later. Or, really what i know i should do, take the box off next weekend? The new box i've just bought will give me a higher final drive so it'll be quicker anyway

Gearbox's often drag in neutral with the wheels free and the oil cold this gets less noticeable as the oil warms & thins and is normal, I often trip ABS lights on by accident freewheeling cars on the ramp due to this condition (fronts spin rears stationary) like Stevie
said already the clutch has nowt to do with it
