Sorry to have to ask a question that's probably been asked so many times before. I've tried the search but it's not much use.

I probably need a replacement gearbox for my Cinq as it recently seems to have started making a noise it shouldn't.

Anyway....

I read in the last week or two someone mentioned number, eg 531 or 315 or something, for a just right gearbox. IIRC, that was a version of Punto Mk2 6 speed.

What would that number have been please?

Alternatively, can I obtain and replace the input bearing (was suggested, I have no clue as to the noise) on the Cinq 5 speed box? Impossible to do? Not worth the effort?

Thanks.

C.514.6.10 is the code for the Mk2 Punto gearbox.
Remember these gearboxes are designed to run with bigger wheels than 13".

Thanks. Is there just the one mk2 Punto box? No variants? There seems to be at least three (if not twice that?) for the mk1 Punto.

The Mk2 petrol has 2 variants. C.514.5.10, 5 speed and C.514.6.10, 6 speed.
The Mk1 I am not sure on what variants. The ratios between the 1100 and 1242 16v 6 speed may vary but are C.514 type.
You can also use a gearbox from a new shape Panda. I fitted one to mine off a ~2006 1.1 model.

Not making a race car. Replacing with a 6 speed appears to be the popular thing to do.

Shorter ratios in 2nd, 3rd, 4th, will make it generally a little bit faster unless rev'ing all the way to 7000rpm through the gears. I ever fit 14" wheels it'll make up for the otherwise 4%, or so, drop in speed up. Slightly longer 6th (than existing 5th) may mean a little quieter motorway cruising, more so with larger wheels.

The extra gear, 5th, might make for slightly faster motorway overtaking. But I very rarely go on the motorway. It's perhaps meant for hauling five people and luggage up a motorway hill in a Punto.

On Clubcento, maybe here, someone published a list of ratios for Punto 55/60/75 and top speeds with the 13 inch wheels. Quite a lot lower for the 55 and 75, eg, 93mph at 6000rpm in 6th. Meant for 15 or 16 inch wheels perhaps. Longer for the 60.

The downsides are that I don't want to lose steering lock nor faff around with the rack to fit a spacer that I'd have to get made by someone somewhere somehow.

Thanks for all the info. That could be my best choice to use a newer box from a Panda.

Was that a five speed? Were the ratios the same as the Cinq?

The Panda gearbox is a 5 speed and works really well with my 1242 engine.
Not sure about the ratios but seems better than my old C.514.5.13 Seicento sporting box.
