Check the obvious connections and alignment of the MC. If it's on the piss it may draw air in during movement. If nothing obvious presents itself topside it's likely a CSC issue. Doubly so if there is black gunk building up in the fluid. Also if you feeling the car move when the syncro's are trying to brake the input shaft motion you're wearing them very quickly. Also, if the clutch point has changed without any mechanical reason (ie after you had the correct PP installed and the crush depth set) but after the MC was changed it's possible the adjustment is incorrect and you're not getting full travel out of the MC. Ok I'll check all the fittings on the MC and see if I can see any air bubbles in the resovoir. The MC is a remake of the factory one with metal instead of plastic so hopefully it doesn't need readjusting. How much would it change between MCs?

Also if I do need to drop the box, can you recommend any clutch experts in Adelaide? I used to do boxes in my driveway but buggered if can be bothered trying to do that anymore.

Said the pressure profile feels wrong, eg when you put the clutch the floor it should feel lighter as you get closer to the floor but mine feel linear/heavy the whole way despite the takeup point feeling normal. Going to drop the box and he will set it all up on the bench to figure it out. Clutch is still in warranty so hopefully not an installation issue and something has just failed.

rollex Member 683 Member For: 10y 5m 1d Gender: Male Location: Australia Posted 20/12/16 12:07 AM Author Share Posted 20/12/16 12:07 AM Ok so the box is out and he bench tested it and said the clutch is completely disengaging and functions fine. He said the spigot bush is pretty average and he suspects it is transferring power to the box whilst the clutch is disengaged causing the crunching. Other than that he said it is quite strange as it is a needle bush and even when dry shouldn't be too bad however there isn't much else that could be causing the problem. Fingers crossed all good once he changes that. 1 Link to comment Share on other sites More sharing options...

The rest of my post was incorrect, so I deleted it. Edited 20/12/16 01:01 AM by arronm Link to comment Share on other sites More sharing options...

Also when driving the takeup point was always 1 inch off the ground. The clutch worked fine for over a year before this problem occurred which suggests something has broken. Also if that was wrong it wouldn't be inconsistent with it working fine some days, currently it is random. Some days (hot or cold) it disengages fine however it has steadily gotten worse over the past few months. He remeasured everything up for good measure (lol) and said there is nothing wrong with the clutch or the setup.

What do the splines on the input shaft look like. Plate could be binding Link to comment Share on other sites More sharing options...
