Hi all,

We have recently bought a 75 diesel tourer. I've noticed that the clutch appears to slip at 2k rpm under full throttle. Having spent some time investigating I've found the clutch master cylinder is weeping from around the dust boot. No trace of fluid from where the box and engine meet so I'm hopeful the slave is okay.

I've also noticed that when driving, putting your foot behind the clutch pedal and attempting to pull the pedal upwards even though it doesn't move the pedal.. the clutch doesn't slip. So.. I've bought this master cylinder.

Upon attempting to fit it, I found removing the current master cylinder marked LUK is proving difficult to remove from the bulkhead but I'll sort that tomorrow, just pull the full pipework through the bulkhead.

Question is.. the Luk unit has a nut fitting at the begining of the nylon pipe where the original ap unit does not. So.. if I'm to swap the pipework over will I need a new pipe to fit the original ap unit fitted at factory?

Thanks
Rob
