Hello all.

 

I recently purchased a non-running 1978 1275gt Clubman. 

 

We have got it running but having a few problems with the hydraulic clutch system.

 

We have replaced the slave cylinder, and most associated pipework. Bled the system twice but I am still loosing pressure at the pedal. It comes back after pumping the clutch but disappears again.

 

Whilst tinkering with it at the weekend, it developed a noise that sounded like it was coming from the bell housing and disappears when the clutch is dipped.

 

Can anyone give me any ideas, I would love to drive Winnie the Mini this summer 😊

 

Thank you

Sounds like the master cylinder seal is worn out and the noise from the clutch could be the throwout bearing.

Thank you for your reply.

 

I will give the master a bit of TLC and that should hopefully solve that problem.

 

Forgive my ignorance but I am assuming its an engine out job to replace the bearing?

 

Thanks for your help.

As said above the throwout bearing can be changed with the engine in - just support the engine and remove the end cover and mount.   Though some of the bolts can be a real pain to remove. :xxx: :xxx: :xxx:
