    Default Clutch Problem

    Now that I have fixed the boost problems that my Q4 had, it has brought to light another issue. The car drives fine in 1st, 2nd and 3rd gears, but in 4th gear, as the boost controller allows the boost to edge up towards 1.1 bar the clutch slips and the rev counter quickly goes to 6.5k RPM. So I am going to have to remove the clutch and replace the clutch plate. Not what I'd hoped for really! I have a few questions....

    1. I can't find in the manuals on this site the section on how to remove the clutch - which manual is it actually in?

    2. Please tell me that you don't have to take the engine out to remove the clutch?

    3. Any recommendations on a clutch plate for a Q4 that is just to be used for track work?

    Thanks to all who helped with my boost issues.... JimN

    I think clutches like this are good for heavy usage: http://cgi.ebay.co.uk/OMP-Racing-228...QQcmdZViewItem

    Engine can remain in place.

    I am sure Steve knows the where abouts of the manual to change the clutch...

    No Haynes manuals for these cars unfortunately

    From what I can make out in the manuals, you have to remove the gearbox side suspension and drive shaft, as well as the complete lower suspension cross member - prior to removing the gear box and then the clutch. Its a bit hard to tell as there isn't a single manual for the whole operation. Can anybody who has performed a clutch change on a Q4 give me a few pointers. I'd like to remove the minimum amount of "stuff" to get the job done. As I don't have a hoist this is going to be a job done on my back on the garage floor I guess - how high up do I need to get the car to get this job done?

    thanks JimN

    did it like that to my twinny also.. better to remove the crossmember, even if you don't have to... gives a bit more room for manoeuvring..

    Get the car at least 50 cm off the ground so the box can be taken out easily. try making a ramp to hang the engine in, or support it in another way, don't trust just the engine mounts to the right of the car, that's how you get a nose like a bulldog

    Jim...very nice indeed. Leaving a Corvette standing....!

    The grill on your Q4 looks interesting, could you post a picture if you get a minute?

    yes, it does have insert thingy's but they sure look like they were made as part of the original bumper. This car is a December 1994 build.

    .......... I got the following from alfa155.org... Can anyone confirm this procedure / order for the Q4. I have looked extensively at all the manuals but I'm really confused as to what parts of this are different for the Q4. Do you really have to remove the lower cross member for the Q4? (and hence the exhaust (front)).............


    just a quick running order,

    Jack the car up & get the wheels off & on stands
    loosen driveshaft nuts,
    split NS suspension & remove driveshaft
    remove battery & tray,
    remove slave cylinder & disconnect speedo & reverse switch
    support engine,
    remove starter & gearbox mounts
    loosen subframe bolts/remove NS ones,
    loosen/remove bellhousing bolts,
    remove gearbox,
    remove clutch,

    refitting is reverse of removal....




    ........


    all help appreciated.

    So far I have jacked up the car, and removed the gearbox side driveshaft... not really sure what to do next.

    Ok, so I will remove the exhaust and the xmember - do i have to disconnect the drive shaft that comes out of the differential and heads towards the rear of the car to get the xmember out?

    I think the gearbox and the centre diff will have to come out a one piece - so you will need to disconnect the prop and the two front drive shatfs. Sorry I cant be more helpful

    I will try and sort some pics if it helps

    Sorry, I thought I had some better photos but these might help a little.

    I think you might be able to leave the centre diff in place actually and just remove the gearbox.

    Thanks for those great pics.. they will really help, as its hard to see what is joined to what under the car. At least I can see on your pics as well where the starter motor is!

    Thanks again..

    While I was taking off bits to get the clutch out I was surprised to see that the car has an exhaust gas temperature probe in the exhaust system, as its not mentioned in the manual that specifically covers the Q4 exhaust removal.

    www.nielsen.org/alfa155Q4/egt.jpg

    Is this something all Q4's have?

    Nope, never seen that! Does it look like someone has put it in as aftermarket?

    Wish my flexi pipes were in that gooder condition!

    Was it connected to anything? I had a small "something" on the V6 exhaust but never worried about it. My V6 was a Japanese "Sport" model...
