Car Forum / MINI / August 2004Vibration - clutch/flywheel
Hi all I had my clutch and gearbox replaced last year and when I got the car back there was almost unbearable vibration from the clutch area. the bloke said leave it for a few thousand miles and it would stop. well the vibration decreased but yesterday I replaced the top steady bushes and the vibs are back again. it doesn't matter if the clutch is pressed or not and it is there throughout the rev range. any suggestions to the cause and remedy? it is a verto clutch on a 1988 uk mini. cheers Barnaby > Hi all > [quoted text clipped - 12 lines] > cheers > Barnaby He *DID* line the 'A's up didn't he ? My first thought, did he align the clutch plates up with an appropriate sized clutch tool? You wont be able to answer that question until the end cover is removed to discover if that is the case... jono  SignatureBarspeed Mini`s - Devoted to the Classic Mini "Persisto Transverbero Adversum" Email - barspeed@hotmail.com The Rover Mini Se7en Register - http://www.geocities.com/minise7en2001/ Barspeed Mini`s - http://barspeed.topcities.com Barspeed Mini`s Group - http://groups.yahoo.com/group/barspeed Barspeed Motor Album - http://barspeed1.topcities.com Ford 100E Group - http://autos.groups.yahoo.com/group/Ford100E If you have received this email in error please click below. barspeed@hotmail.com Barspeed is not a company or a profit making organisation. > > Hi all > > [quoted text clipped - 14 lines] > > He *DID* line the 'A's up didn't he ? thanks for your replies Jim wrote... > > He *DID* line the 'A's up didn't he ?

However the Flywheel and the Pressure plate, and the diagphram spring plate do have to be correctly matched when put together. There are 3 "legs" on the Pressure plate that both onto the spring plate, and if the A mark on the Pressure plate isnt matched to the A mark on the Spring Plate, and to the 1/4 mark on the the Flywheel, then they probably wont be in balance. So your solution may be take the clutch out, split it all, and then rebuild with the correct alignment.

Always remember to leave out the bell housing bolt at about the "7 o'clock" position, (when looking at the engine form the off side), or replace it with a shorter bolt. This is a real bugger to get out/in, if you are doing the clutch in Situ. The rest is a piece of piss - apart from clearing the brake servo out of the way, undoing the bottom O/S engine mounting, undoing the flywheel nut (big socket needed, screwdriver in the flywheel teeth), splitting a stubborn flywheel off the crank, re-bolting the top engine stabiliser afterwards, walking on water etc Have a nice weekend!

I've been out there today having fun. every thing is apart there was no obvious misalignment there were no marks, but it is a verto so only one way it will fit properly due to the location lugs. I did indeed have fun with the "7 o'clock bolt" and also the one below the engine mount. luckily I don't have modern fangled servos to deal with. was a good exercise though and now I see how the clutch works. thinking about having the flywheel assembly balanced to see if that solves it. thanks Barnaby > Always remember to leave out the bell housing bolt at about the "7 o'clock" > position, (when looking at the engine form the off side), or replace it with [quoted text clipped - 30 lines] > > > > Which is only about 1/10th the amount of fun as what it sounds like. |
