Hi all

Clutch has been playing up for a while, biting point has got incredible high and almost slips on first and second.

However on the way home from Nottingham today i heard a "Bang" and lost 1st and 2nd was extremely problematic.


Has the Gearbox decided to blow, or has the clutch plate gone.

Any thoughts on PRICES and What has Happened?

Thanks Alot.
 
depends on if u do the work urself or not and if u use 2nd hand parts from a scrappy. cost me 350 to change clutch, but a lot of ppl here got theirs done for 200ish. fiat dealership want upwards of 500 so all depends on ur garage rates. gearbox will be more expensive. prob up to 600+ for a new one or as little as 100 for 2nd hand box + fitting.
ill let the more experienced ppl say what could be wrong.
 
Does 1st engage with the engine off? If so it's likely to be something in the clutch. If it won't go in with the engine off then you need a gearbox as well. That's only an educated guess, can't be 100% without taking the box out.
 
First of all, if you are still managing to drive anywhere I would keep off the motorways unless you have breakdown cover (though Leeds to Nottingham is a bit tricky without the M1).

You say that clutch was starting to show symptoms of high bite and slipping a bit so I would suspect that first. However, these clutches usually break before wearing out (i.e. slipping is less common). The thrust bearing cuts into the tines of the pressure plate. Sometimes you will get a bang as one of the tines breaks off. The clutch gets hard to depress.

There could be a gearbox problem instead or as well but probably best to eliminate (or fix) the clutch first.

With engine not running, can you depress the clutch fully without undue pressure or strange noises? If "no", there's more than likely a clutch problem (though it could be gearbox issues including linkages).

With engine running and clutch depressed, can you engage all gears (if necessary lifting and re-depressing clutch)? If "no", there's more than likely a clutch problem.

The only "real" way to assess the clutch properly is to remove the gearbox. If you aren't about to do that yourself, time to start shopping around.

There is a guide on the forum if you want to see what's involved.

I agree the Bang could of been the clutch breaking up
And Been Fluid based - No cutting corners either :( (ie make Clutch bite harder)

Eitherway - i'd be getting clutch checked out first, and see what happens there

If new clutch is on - and it still causes problems, then i'd say box has gone too

Dont use the M1 =P i use the A1 and A614, more fun to use the back roads, and the M1 is chaos around sheffield at rush hour, A1 tends to be quiter untill m18 at Doncaster.
I use the A1 as its easier from where i live to get to (not Leeds city, just generalize with Leeds)


Right, down to business;

I can engage all gears with clutch off. no weird noises or undue/excess force require (with clutch up and down).

Before this happened 1st and 2nd were getting noisy when selecting (speeding up noise) e.g., when going 4th - 3rd - 2nd, or when building speed 1st - 2nd - 3rd.

jacked the car up today, no obvious leaks or cracks in the gear box. all seems fine. nothing seems different to when i've had it up before.

planning on taking engine out when i have chance.

talking to local garage explaining symptoms and what happened they believe its the clutch at the moment, but say they cant be sure until the engines out. i use these guys regularly and are an independent FIAT and VW specialist.
 
Little more insight today.

engine out and and gearbox off;

clutch is in pieces (before i took it out). gearbox seem ok, no leeks or cracks in the casing. and no puddle of fluid on the floor.

before dismantling tried selecting gears with engine on and off, 1st is un-selectable in both scenarios. (presuming that the gear itself has gone) rest seem fine.

so now on the hunt for a clutch and gearbox for a 1.2 8v 55plate punto.
if you know anyone please post
 
fit a 6 speed while your at it :p

Haha, ive seriously thought about it. ;)


Right then...

Turns out that where the shaft goes from the clutch into the gear box there was a small crack =(

Oil has been seeping from inside the gear box onto the clutch which explains all the symptoms

Noisey gear box = Lack of oil in gearbox :bang: (not completely dry thank fully)

Slipping clutch = Oil on clutch plates (n)


Gearbox is in Chleckheaton Gearbox and Clutch nr Bradford repair at the moment and will be retuned tomorrow fully reconditioned. (I seriously recommend these guys for the yorkshire drivers, if you cant drive the car they will pick it up for free. and they have a lot of experience and good service quality) :worship:

So car will be on the road by Thursday all been well =D
 
Out of interest, why take the engine out to access the gearbox/clutch? Both are removable with engine in-situ.

I personally didn't know you could do them separately and was removing from above. the jack i've got is enough to get under the engine but not remove anything, simple wheel jack.

the garage used the lift and have removed just the gear box and clutch from below.

(working with what you've got :eek:)


By the sounds of it, it is been welded. just a "simple" recondition. hopefully there is no lasting damage to gears due to the leak
 
My concern would be why did it crack.

the 'box can be taken out from below without a car lift.
Jack the car up high onto axle stands and lower the box with the jack onto a plank & drag it out from under the car. Much easier than taking the whole lump out. But as the OP syas you use what you've got to do the job.

Some of these would be nice to have in the garage -

I was thinking the same when i was talking to the garage. They mentioned the bearings but i couldnt workout the relation between the bearings and a crack (maybe you can) :(

also that everything would be sorted in the recondition. so my last "simple" was incorrect. so hopefully bearings and internal damage is replace. which i guess is why its "recondition" :confused:

I would love stuff like that, but literally don't have the space. i have a 2 car driveway, with no garage. =/ i have a small "storage" area about 3x4m. which is where the engine got put out of the weather :)

i think i could proberbly do it thinking through, but not much space. Rather not try it, i can get it out from above so will stick with that method when the situtation requires (or take it to the garage (y) )
 
Car is back on the driveway =D fully fixed (y)

Offical repair list from Chleckheaton Clutch & Gearbox generally says that 2 of the bearings had collapsed and caused a leak of fluid onto the clutch. gearbox fully reconditioned (ie all gears checked, new bearings, oil, etc) new clutch also put in

now to get used to a stupidly low and light clutch peddle (had got used to the high biting point on the old clutch :cool:
 
Mine has a low biting point ever since the new clutch. I dont much like it either.

A garage lift would be nice (just dreaming/nighmaring) but who has a tall enough garage never mind having a garage in the first place.
