I have recently bought a Mal Wood CSC for my BA XR6T. I live very remote and have been in talks with the local mechanic about changing it. He has never done one before and seems tentative and worried about doing the procedure, he said he has read up on it and asked a mate who has done it before and is quoting me around 5-8 hrs to remove the box. My question is from my understanding you disconnect the box from bell housing, remove or slide back box, remove CSC, reinstall new CSC, bolt box back up. Is it that simple or is there a lot more involved. He is telling me that I should be replacing my clutch while the box is out. I said well I think the previous owner has replaced with some form of heavy duty one as the clutch is very heavy and bites hard.
