Cant select any gears, HELP

This thread is carried over from CHITCHAT so apologies if you have already read it.

 

On leaving Eastbourne after this mornings mini Blat from Devils Dyke to eastbourne my gearbox failed on the outskirts of eastbourne.

 

I had to drive the last 30 miles in first gear at 15mph from easatbourne to burgess hill with no ability to use the clutch or change gears. by the time i got to the Firle straight between eastbourne and lewes on the A27 i had a tailback any rover driver would be proud of, what a whopper.

 

I fiddled with the clutch cable (of which i have a spare) and that seems to work ok but with the engine turning over you CANNOT select any gears other than neutral.i had to put it in 1st, start the engine (without the use of the clutch) and kangaroo up to speed and stay there.

You can select all the gears with the engine off, but thats not helpful.

 

Dipping the clutch with the ignition on makes no difference to anything either

 

Any ideas as to what this might be would be gratefully received

 

Theres talk of it being a Clutch release bearing?

 

Its a caterham standard 6 speed 1.6K Supersport, lightened fly, with about 7000 miles on the clock, was fine this morning but now its dead.

 

Hope someone has an answer

The fact that you can select gears with the car not running points to a clutch

related problem.

 

Put the car in first gear (engine not running), put your foot on the clutch and get someone to try and push the car. If car will not move then it is clear clutch is not disengaging engine from gearbox.

 

Assuming this is the case you then need to check cables, pedal box etc.

I have had a clutch release bearing break up and the debris caused the clutch to seize. I drove back from Amsterdam with it like this, but with crunch gearchanges I was able to get most of the way in sixth.

Many thanks lads

 

I will try the diagnosis techniques tonight to try and narrow down the problem.

 

Having limited mechanical knowledge i will work through the possibilities until i define whats not doing what it should.

 

regards

Not too sure of the commonality of all of the internal components between the six speed Caterham box over a Ford type 9 five speeder, But I lost gear selection in my Type 9 box, because the roll pin on the selector shaft/fork assembly in the top of the box fell out, (apparently a known problem) leaving me with only fifth to get home with. it might be possible to lift the lid of the box in situ and get someone to go through the gears. if the shafts move but the selector fork does'nt , this might be the problem I wish I had known at the time that it is possible to fix this problem without getting the box out of the car. If it is the roll pin that has gone, it can be retrieved from the bottom of the box with a magnetic pick-up tool. A new (preferbably double) roll pin can then be fitted with a bit of dexterity. The racing guys usually wire lock these pins into place as a belt and braces safety measure.

good luck

Sorry to say, but Nige is your best bet... he knows his way around every thing outside the engine.

 

Bottom line is... its engine out time, so what up grades are you thinking about?

 

We have a friend's HPC in bits at the farm and it, like me, is on the Bordeaux Blat - if you need the W. Sx Sevens workshop... its either Nige or wait until I get back from Bordeaux, but then of course I have silage - can you drive a tractor?

OK

 

I tried the diagnosis technique as suggested by Alicat last night.

 

1. car in first gear, engine off, try pushing = no movement

2. car in first gear, engine off, try pushing with clutch pedal down = car moves 🤔

 

Now with the engine on and off i can select all gears with NO crunching *smile*

 

It appears to have sorted itself.

 

I also tried Steve Robinsons technique of doing VERY SMALL adjustments to the clutch cable nuts by the pedal box end and all seems as it should be.

 

will try a careful blat tonight round town and no doubt will report back if its all gone pear shaped again.

 

PS John Howe - I can probly drive a tractor as long as the field is fenced in so i cant get lost *smile*

 

Thank you for all the help

John, just a word of caution!

 

If you problems were cured by taking up the slack on the clutch cable, then you need to say why did I need to adjust it?

 

I suggest it is most likely the begining of the end of your clutch cable. If you always carry a spare, then no problem, but if you don't - yesterday was the day you should have ordered a spare ....

Hi John

 

Ever since the first cable snapped on the way to redline i carry a spare.

 

If you think it might be the begining of the end of my current cable i'll keep an eye on it.

 

the present cable has only been in since february, can they really last such a short time?

 

either way I'm prepared,

 

now where did i put the spanner set?

 

regards

Its most likely that the part that falls in to the bellhousing when the clutch cable brakes caused your problem. It jams the clutch and the only cure is to put the car in gear, press the clutch pedal and have someone push you back & forward.
