What about just undoing the black line in the red circle and screwing to where you want it to go?
I take it a clutch damper is the same as CDV?

 

@johnlear did this some time ago. He never takes pictures though which would be useful but can detail precisely. He has not been so active of late but I think has been caught in major engine work. I don't remember mention of unusual thread sizes.

Clutch hydraulics are usually 5/16" pipe (7.9mm) rather than the 3/8" (4.75mm) brake pipe size.

Your slave cylinder thread size is M12x1mm. The threads at the pipe junction will be the same size.

 

I bypassed it on my AR 147 1.9 16V, The clutch peddal was a bit more direct and straight forward. Rapid changes were also better.

 

the question is ... for what reasons exactly did Alfa put this part between
that must be clarified, cause we are talking about the clutch

 

The clutch damper is just to reduce speed of clutch movement to lessen the strain on the clutch if you release it too quick.

When I did the clutch hydraulics on my brother in law's 916 GTV I removed it and that improved clutch feel greatly.

 

@thomash you are correct

It's more for sloppy drivers and introduces clutch delay

 

On my 147 1.6 there are no threads on the damper. One would need to fabricate a new line, which is difficult as the connection on the master is not threaded but some sort of bajonette,.like on the slave

 

Does a clutch damper work for both pedal directions ?

 

on a 147 16v yes

 

@mechtild , try this.

It would probably need some 5/16" pipe made with the correct flare as a bypass.

Lots of people have used the Busso drivetrain in Stratos replicas. I don't think anyone has bothered to fit the damper. I certainly didn't and it's been fine since 1996...

 

Thanks all, ordering a 15cm long flexipipe with m12 1mm thread male unions on each end, hope it fits! Loosened out the unions to make sure nothing snaps and all good. ^speaking of Lancias, the clutch damper on the 156 is the same as Lancia Delta evo1 & 2s!

Male? Isn’t the damper it self with female unions or am I just being very Swedish?

 

I did this on my GT, I don't know if the specs will help though as the GT has a different damper design.

It did make a huge difference to the pedal feel. I had an issue with an inconstent pedal before and this smoothed it right out.

 

While on the subject, anyone knows if my car has a clutch damper? Also, is it dual or single mass fly wheel?

 

Best to open the bonnet and have a look for the damper.

 

@AlfaGermany , it smooths out any vibrations which may reach the pedal.

@tadaska , 147 and GT cars seem to use plastic quick clip fittings probably on fairly rigid plastic pipes. This should be the ePER page for your car. I think you would have to be creative possibly with a suitable piece of steel pipe and possibly some heat and hose clips.

 

My valve and all connections are toast but still functional. I noticed this after removing the battery tray for the first time, have only had the car a few months (05 147TS).

I don't have the ability to service this at the moment by splicing in, but I can take it out and take it somewhere. Maybe the old fittings are salvageable-- is this the only way to proceed? I assume no hose can be purchased without the valve, which would fit both ends (some Alfa or Fiat part for example)?

Incidentally, when I saw this I thought oh great, some random rusted s* to replace, but as I've read up on the improvements (John Lear's AU thread notably), I'm seeing this as an opportunity for an unexpected upgrade!

 

My rule upon sighting something like this is to not touch it. If it works, leave it alone. Most likely it wont fail while you own the car.

 

Heres what I ended up with with, removed the damper/old pipework completely to de-clutter and did a rebleed. It would of been hard to make any of the existing pipework work.
So far so good, clutch pedal feels normal again, not noticed any vibrations.

 

@IgoRR , are you able to post a picture of your modified clutch pipework so other (and I) can see what changes you had to make due to the 147 and GT quick clip connectors.

 

Hi mate,

here are some photos of the delay valve opened and how I bypassed it.

 

Where did you buy the fittings?

 

Didn't buy the fittings, had my hose with the delay valve deliver to a hydraulic shop that did the work.

 

It looks like some sort of sleeve joining the 2 parts. How is a bit of a mystery but a hydraulic shop would know.

 

If you have a steel line like that in some production facility and it get's knackered or broken they have ways of fixing it yes. Exception is that this is a hydro line for a car clutch/brake system.
