Technical Clutch change

[bikes-for-me]

Just wished i had a workshop,electric ramps,air tools ect.
Next time i think i will invest in some higher axle stands,and a jack that jacks higher.
I was reading a thread about 2 blokes who have been fixing cars for 30 yrs,they did a multipla clutch and said they would never touch one again.

Wimps ! Although when i had my Alfa i paid for the clutch on that as it was a 4x4 and engine room was a no go

:bang: Got it all together now less wheels,still on stands,went to try it and clutch does not seem to work.The clutch pedal seems very light with no bite on it,did bleed it but did not make much difference.
Will have another go tomorrow,just hope the clutch release bearing did not fall out when putting gearbox in.:bang:

 

[JTDman]

No way man, i seen your post and thought great hes finished.
Hope its not so bad.

:bang: Bloody guted,dont wont to strip it all again.When i took my clutch release bearing out .It was all broken in bits,so i did not have anything to go by,and dte cd is not much good.I fitted it with the cone facing to clutch,and the arm with the extra leg on to bottom fork. How did you fit your clutch relase bearing,if i have to take it out again, i shall be investing in higher axle stands and trolley jack.
If i take the plunger from the clutch slave cylinder,and free the pressure from the clutch release fork arm.I can move the arm in the wrong ie to the wing or battery side easy,but if i try to move it the right way ie the way the clutch slave plunger works,i cannot.Not sure this is normal. The clutch slave plunger moves the arm ok tho.
I am not giving in till its working,so all tips most welcome.Taking the gearbox off is the last resort,so what can i try first folke,its driving me to drink.:bang:

 

[JTDman]

Domed front of the bearing pointing towards the clutch, did you try the fork with the bearing in place before you fitted the box back on? if so id of thought it would be ok unless its fell off

 

[JTDman]

Even if you did need to re fit it i would have thought you would get away with splitting the box and just levering one side open to do it.
Fingers crossed mate.

Went and brought one of theses easy bleed kits that you run off tyre at 20psi,to bleed the clutch.My clutch pedal feels so soft,even tho it stays up,not sure if its right.
It did not make any difference,but i thought the fluid would come out with more force then it did,no air bubbles tho unless someone puts the clutch down while bleeding.
If the release bearing not sitting right,would that make the pedal feel so soft.I wont to try all options before i split gearbox.Think its looking that way tho,but would be gutted if split it and its was ok.Perhaps a new clutch slave :bang:

If someone can can check this for us and let us know it would be a great help.Thanks

Come on dont be shy,we need more people like JTDMAN.:worship:

Im not able to push the arm in the "right " direction, sorry i cannot remember if the arm would travel in the "wrong" direction.
Too much pressure to operate the arm by hand .
Mine was really lite when i first done it then got heavier.

Bit stuck on what to do next,do i take the plunge and drop gearbox,or do i buy a new clutch slave and try that.Thing is clutch arm works when pedal down,just seems very light and not doinga thing ie same as changing without using clutch pedal.

 

[bikes-for-me]

Big thumbs up mr JTDMAN,you are the only one to be bothered to help.:worship:
Think i am going to drop gearbox and see if release bearing is put on ok.The clutch assembly its just a matter of putting the clutch plate inside the pressure plate and bolting it up,and then align it up with a centering pin or socket,if i am right.
Now the release bearing,the cone side faces the clutch pressure plate.Then the arms on the release bearing go around the clutch release fork.The release bearing has arms one side is like half a T,does this go to the top or bottom.
I have took photo of old bearing if it posts.
Also do you just fit bearing lose,of is it fixed in and does the release fork arm have to be in a set before you fit gearbox.
I ask because i have downloaded marea manual,and it shows the clutch release arm positioned towards engine before fitting.And then it shows moving the fork arm back to direction of n/s wing once gearbox fitted.
I wont to make sure clutch and bearing are all fitted right this time,dont wont to drop gearbox again,all help very gratefull.:worship::worship::worship:

Hi bikes-for-me

I'd be only to happy to help with checking out the clutch fork movement, but I am currently Multipla-less. Guess where it is? Yep, you got it - having a new clutch fitted!

So, sorry I can't help.

 

[JTDman]

Well as far as i know the bearing can only be fitted one way, i mean the way the arms are i just made sure the bearing was pushed all the way back onto the fork up against the shaft bearing holder .(if that makes sense.)
Why do you think there is a problem?
I thought we had decided the shafts spinning was ok?
Hope your not loosin the plot yet.

When i put it all together less the wheels,left it on stands.Started it and went through the gears there is no clutch ie if you put it in gear without using the clutch pedal its the same if you use clutch pedal.No clutch bite just crunching,if that makes sense.
My partner helped me put gearbox in and it was a struggle ,the clutch release bearing fell off at first attempt.If you say there is a bearing holder,then it shouldnt fall out if put in right.This time i will make sure i have a proper gearbox support .Did you move the release arm forward before you put in.:worship:

 

[JTDman]

Wish you lived bloody closer , what i meant by the holder was just the tube section that holds the input shaft seal. The release bearing travels up and down this, ive gotta admit im a bit stumped with what is going on with yours at the moment without seeing it.
When i fitted mine the bearing was all the way back into the bell housing on the gearbox as in where it would sit normally.
Dont forget you need to filll your gearbox with oil before you go running it, still dont know how you dont have drive and are able to change gears without using the clutch unless you start it in first then match the revs to the next gear.

 

[JTDman]

Thinking about this and i hope not , it reminds me of when we did mine the first time round and fitted the clutch the wrong way round.
It would go into gear ok with the engine not running but as soon as it was running it wouldnt, we thought the clutch plate was oversized and burned it in:idea: 4 th gear and clutch slip and it worked but as ive stated it was only in contact with the flywheel bolts and not the friction surface.

Pretty sure fitted the larger cone side of plate facing gearbox.I think the release bearing might be up side down.Just seen a picture and the arm end with the extra leg looks like it should be at the top,and i am pretty sure i fitted it at the bottom.:bang:

 

[bikes-for-me]

Well got a gearbox support today and going to start to drop gearbox tomorrow and have a look.I just have a feeling its the release bearing,i put mine on with extra arm on bottom but seen a picture with it on top,just that cooky 257 put his on the same way as mine and his works ok.
Any tips on checking that the clutch is lined up,i got a tool from machine mart that says it does 90% of cars but does not tell you how to use it.I screwed the end in that matched the inner clutch plate,then put the best size one on next to that that fitted the pressure plate.There is a hole engine side put end of tool in that,then screwed pressure plate up.I think the clutch plate needs to be lined up with this hole on flywheel side ,as when i took the old clutch off it did not look 100% lined up with the pressure plate.Perhaps some one could advise .
