cluch problem

[gedis]

i have gearbox of the car, and cluch including the flywheel, we fitted flywheel with burn marks on another car and it works perfect(not damaged/twisted). the end of the crank looks very good with not a mark on it, i work on starlets and other 4e cars alot and never had a problem like that before done about 40-50(8 of them is my car ) gearboxes but this is just does not ad up

looks to me like they havnt been aligned properly.

alignment is not normally an issue sx-turbo....as if u dont get the clutch aligned correctly, then the gearbox gives extreme trouble to get fitted up.....so everything needs to be alinged correct so that the gearbox actually goes on

and see that gedis has done this about 50 times now....i think its fair to say he has the alingment thing down to a tee...lol

got another box again and the same problem again, something is very wrong

 

[gedis]

just found one of the dowels between gearbox and engine missing, could that whats causing a problem?

 

[gorganl2000]

those dowels help take a lot of pressure off the box "twisting" from the pressure of the clutch system-----along with the bolts

should be worth it to see if they sort out the problem

hey i have your same problem exactly !! me thinks that slave piston is not forcing the fork to work the thrust bearing enough !! did u solve your problem pls ??
thx balulli

 

[Andymodic]

its a tough one, have you checked the fork??

 

[balulli356]

problem solved i put a spacer under the clutch pedal and therefore the pedal is pushing the piston of master further on and gears go perfect now (btw clutch got really hard to push now but dont care as long as it's fine

after seeing all your problems put a dial gauge on the flywheel bolting surface, rotate the crank and see if its flat and true and spinning correctly.

another one that i've seen do this is if there is alot of thrust movement in the crankshaft itself. i'm not talking huge but it doesn't take alot of cause these kind of problems. With the dial gauge still place use a bar between a couple of bolts or something to try and pull the crank out the engine. there shouldn't be hardly any movement. had a gt4 do this eating clutches, had a right headache with it. then it started stalling the engine when you pressed the clutch in, eventually it started knocking so stripped it down and found the thrust bearings were gone. so clutch engagement would push the crank instead of doing its job properly, then when it got bad when you pushed the clutch in the crank would push against the failed thrust bearings, move inwards to far and crank would catch on the block causing it to stall.

worth a try to eliminate it atleast.

Hope that helps
