clutch removal etc.

Search for Techniclutch on alfa155.org - they don't appear to have a great rep unfortunately.

My clutch is from here:

http://www.walkers-garage.co.uk/shop...en-uk/d38.html

I got the alcon 6 paddle version+upgraded pressure group.

Very happy with it. It is still possible to use a bit of control, although there is a very short travel between on and off.



They also have lightened flywheels listed.

I had a simple question.
I'm not really good informed about the clutches available for our car, but I can say that I have no trust in such sintermetallic clutch plates.
Why don't you use, if you want to do a real upgrade
(because that's what I would do) a multiple disc clutch?
Something like this:

it's 67 and 77 mm. Just measured the old tube.

Get a 90 degree 76 -> 63 mm reducer elbow . This fits perfectly. j1v has written about that long ago and I can confirm it fits.

Your flywheel looks perfect.
Strong clutch cover is what you really need, or a multiple disc clutch as Gery suggest (given that you drive the car only on track and not in the city trafic).

I wouldn't worry about that seal unless it's damaged. I assembled my gearbox with a old seal and silicon stuff and it doesn't leak at all... Strange in your case.

[mindus]

BTW, it's a good chance for you to check the solar gear wear if you haven't done that yet. I had to make the whole new unit after I've discovered huge play in those small gears...

[jimnielsen]

what about this one??

[arjunior45]

I think it will do the 'work'.

[jimnielsen]

In the end I decide to go for an OMP clutch plate, I have received it now (see pics), so, soon the car can go back together again. One of the advantages of this type of clutch is that you can unbolt the clutch center that contains the splines and have a clutch plate made up with it very simply (the rest is just a bit of flat steel with riveted on friction pads..

[SteveNZ]

Out of interest do they give the specifications of the clutch?

When the plate is worn out you can just get the pads replaced in theory, as long as this does not happen!!!

[jimnielsen]

Steve, its just a clutch plate - I have not bought a new pressure plate at this stage. That's a shocking photo! I hope that does not happen to me! The clutch plate is quite lightly constructed, but looks well made and solid!

yes, but can you imagine what might happen if a part of the 'flat steel' brakes? It happens to me once and the cover plate was made out of aluminum!!!
That's why I do NOT like these kind of 'star' clutch plates.

[jimnielsen]

Well.. I got a 76 - 63mm reducer elbow, but it does not fit - its just to strong to stretch over the 80mm throttle body inlet!! How have others addressed this issue? I can't find an 80mm to 64mm 90 degrees reducer elbow??

help!

[wrinx]

Did you try warming it up?

[jimnielsen]

yes, we put the 76mm end in boiling water, but its a '5 layer' silicon hose and its pretty stiff... perhaps I need a cheaper one??

[Juan AR155Q4]

Ouch!!! I?m waiting to arrive a similar one!!!

[mindus]

Well, it's not an easy job, but it fits. I've did that "job" several times with Samco silicon hose and another one with non branded silicone hose. No need to heat it up. Try to push it hard and at the same time turn. And it slips on the TB.
You're just not persistent enought
Finally, try to use some kind of leverage tool. Did that once but there's no need for it actually.

Look at how beautiful 76 mm hose sits on OEM 80 mm TB.

[AlfaJack]

Silicon lubricant should help no end

[jimnielsen]

I agree that yours looks great - maybe I am not strong enough!

[jimnielsen]

No - It won't go on for me! Epic fail. Hmmm. Its not even close really, the one I have just isn't very flexible..

[AlfaJack]

OK, odd suggestion but can you trim or file out some of the inside?

[Juan AR155Q4]

Mine's arrived yesterday.
I'm trying to fit in a spare TB I've but seems impossible.
It's non branded, maybe isn't as flexible as Samco... or maybe I'm weak as Jim!

[AlfaJack]

I was searching for my boost leak yesterday and took the chance to measure the TB and the pipe.

TB: 80mm but needs to go over an 84mm ridge
Pipe: 64mm but needs to go over a 67mm ridge

I think an 82 - 65 reducer elbow might be better - if available.

[jimnielsen]

Thanks Jack - I searched everywhere for an 80mm - 64mm 90 degree reducer elbow (thats 3.125" to 2.5") Could not find one. So I bought a simple 3.125" 90 degree elbow - and I am going to modify the 2.5 inch SS tube that I use to that it terminates in 3.125" as well.

jim.

[Juan AR155Q4]

What about this?

[AlfaJack]

Looks like you could get away with that
