Default Clutch

Hi friends,
I recently purchased a Rover 75 Classic from a very decent fella who assured me that it had recently had work done on the clutch, replaced along with the flywheel. Some members may recall I asked for advice re bleeding the clutch as the pedal was very low and 1st and reverse gears were sometimes difficult to engage. I have followed the advice to the letter and now I find I can't get it into gear at all. I have now resorted to what the local garage owner calls the stick trick (holding the pedal down with a length of wood overnight). I'm now more than a little concerned and cheesed off as I'm getting nowhere fast, please can anyone help I really hope I haven't bought a dud !!!
Andrew.

Sounds like a slave cylinder issue to me, do you know what parts were used in the clutch change?

Remove the air filter housing and take a picture of the slave cylinder pipework that exits the gearbox at the top.

Post the picture here, we will e able to tell you if it's on the original slave cylinder or not.

Even easier to photograph, as he has a diesel no need to take off the airbox.

I'm still curious as to where in Durham Andrew hails from, bearing in mind I was in Chester Le Street today, Peterlee yesterday, and Brandon village on Monday, I'm generally kicking about and don't mind taking a look for him

When doing clutches on these, we always emptied out the master cylinder using an old piece of slave cylinder pipework plugged into the slave feed pipe, bled out all of the contaminated fluid, some were discharging plenty of black fluid containing particles. This is essential to do as the contaminates will only collect into the slave and do damage rendering the unit eventually as a failure.
This exercise took place doing mine two weeks ago, flushed out 4 reservoirs full before it came clean. As we know the main failure seems to be the slave cylinder for a number of reasons.
Hope you can sort it !

Behold the Frabtel Master cylinder Bleedomatic 2000 (TM)



I go one step further John, and remove the master cylinder piston, clean out the make up valve, and wash out the reservoir with brake cleaner, then rebuild with a smear of red rubber grease.

Followed on by two bleeds, both using an easibleed, first one with the fluid shaken to aerate it, which scours the interior of the pipework then a second bleed with new fluid until it runs clear.

I generally then leave the master pressurised while I have a cuppa, to make sure there are no leaks from the piston, before finally disconnecting the quick coupler.

The master once the condom is replaced, which I tend to do by compressing it against the lid , then blocking the vent hole to prevent it from decompressing, this ensures only the minimum amount of fluid is actually displaced when refitting the lid, can be treated as prefilled "as new" and connected up to the slave.

But as you say, many slave "failures" are actually as a result of not flushing the master first
