Clutch Issues

[i eat dirt]

hey i have recently converted my car to manual and now when the car is going to take off it feels like the clutch isn't lined up 100% and there is mad vibration going through the tailshaft! enough to hear it knock on the tunel a couple of times.

anyway i called my mechanic and explained the situation and said that the clutch couldn't be lined up incorrectly or it just won't work at all, he then explained it could be a warped fly or pressure plate also about ceramic something rather could cause vibrations, but it is an organic clutch soo that was ruled out.

just need to know if i have installed the clutch slightly out can it cause the problem? can i just get it re-aligned?

any info helpful

cheers

Your mechanic is basically correct - if the clutch assembly isn't aligned correctly, then the gearbox just will not go back on.

Did you disassemble the driveshaft during this swap? Or is it a different driveshaft from the original?

same shaft as before,

another mechanoc mate says it could be the spigot bush? but it runs fine with clutch out.

steps i am taking now is machined flywheel, brand new clutch and getting a mech to assemble the clutch.

fingers crossed!!

any other suggestions??

did you know the history of the gearbox you purchased?

sounds like it could be the rear main shaft bearing.

if the bearing is gone, it can allow the shaft that your tailshaft connects to to move.

hence causing movement and vibration. put it up in the air and try moving the front of the tailshaft by hand, you should get very little movement.

hope this helps....

okay soo it is still doing it i have checked the rear main bearing and it seems to be fine.

i did however notice that when i installed the new clutch the spline/shaft (the thing at the front) had a lil movement in it like side to side,

im not sure but i dont think that it should have play, am i right?

you shouldnt be able to feel any play what so ever on the input shaft (the shaft with the splines that goes through the clutch) if you have movment in that id say youve found your problem

gay,

soo i guess i'm looking at rebuilding the box.

does anyone know what would cause that in the box?

like a bearing or housing inside te box being stuffed?
