Google isn't always the answer to everything!
If you wish to Google something try land rover Discovery hydraulic clutch damper.
Or Honda hydraulic clutch damper.
Or Nissan hydraulic clutch damper.
Or take a chance and believe my post which tells you it's not a problem and don't worry about it.
You could even do a search on this site for clutch damper.
It was on this site I saw the info about fiat 500 / panda clutch damper , clutch pedal issues and retrofit.
 
Sometimes the function is also to limit the speed at which the clutch can be engaged and so limit shock loading the drive train.
 
Sometimes when they go wrong they absorb so much of the clutch pedal travel the clutch doesn't disengage fully causing gear selection problems, grinding etc
 
I am totally with you Murphyv310
believe they also help with smoother
Gear changes by smoothing out torque pulses to gear box.
friction plate damper springs also involved. All of that is more springs than I think are healthy.
In case of this petrol Panda it must be fully protected from torque overload!
 
Hi.
Not all DMF's have springs in the driven plate TBH. I don't think the 1.2 has a DMF, the engine mounts are very flexible in this version and it has the feel of a solid flywheel as well.
I can see the reason with the TA, it has a cylinder firing on each turn of the flywheel whereas a 4 pot it's every half turn so to damp out vibration a heavy flywheel would be needed on the TA with its 2 pot engine, a DMF would be the answer but of course DMF's are not exactly light. At anything above tick over there would not normally be a problem. The thing is in days gone by with a 2 pot engine a solid flywheel would have been fine, the 2CV, Fiat 500 & 126 coped fine but the TA is capable of over 100bhp and lots of low speed torque so those pulses need to be damped out, a mere hydraulic clutch damper wont help, so Phils "damper" is a bit of a mystery.
 
Thanks Murphyv310 the whole picture makes more sense to me.
The hydraulic damper fiat is using on diesel 500s/pandas etc is to stop clutch pedal vibration/noise when releasing clutch pedal.
 
If it is a hydraulic damper (and I'm not saying it isn't) it's designed to remove vibrations transmitted via the fluid from the clutch pressure plate fingers and release bearing back to the clutch pedal.

The flywheel/clutch tends to swish as it goes around causing a pulse back through the fluid and this is ment to remove it.

Dual Mass Flywheels dampen and protect the crank and gearbox from excessive torque.

Though we tend to think of these producing something like 145Nm of torque, the intial spike as the flywheel and clutch come together can be massive.
There's a formula to work this spike out, but it's long gone from my mind!
 
To conferm to all those members ....Yes it is a clutch damper and is connected to clutch pipe work.
I sent a pic to SG Petch in york who confirmed the part via their auto data spread sheets..
 
If something has access to the parts data base for Panda 12+
Please check the part numbers for the clutch pipe to slave cylinder(it may be only available as part of clutch master assembly)
Check if part for twin air is same as diesels. If it is then the twin air is meant to have the hydraulic damper.
We have to remember that it is a fiat and may have had whatever was to hand fitted when built.
The pipe with damper cost fiat more than pipe without but it would cost a hell of a lot more to stop production of non damper pipes in short supply.
 
clearly not fitted on all pandas .
The pretender already posted for you that his twin air doesn't have one.
