Clutch clutch clutch..... GRRRR
My fellow Disco Drivers... I need to pick your brains again. Having convinced myself that the clutch had gone U/S I tried to get the gear box out at home on the garage floor. I've changed a disco 1 clutch but in those days I was single, childless (i've got 4 now), had access to a car ramp and walked to work.
After 4 days of drilling out and grinding off the bolts holding the cross members on I ran up the white flag. Local transmission shop reckoned it was the master cylinder, they changed both it and the slave and it all seemed good (spigot bush still screeches but I am aware of that issue).
Until today. Having driven Canberra to Sydney without incident I now cannot engage 2nd gear if the car is moving; i.e. I can't do a 3-2 change. Also, if I park on the drive facing uphill, engage reverse. disengage the handbrake and then dip the clutch pedal, she doesn't roll back.
I am hoping that the system just needs bleeding but I have that chilly feeling.
Grateful, as ever, for the thoughts of the brain trust.

Try bleeding a see what happens. Is the fluid level down? Did the garage use name brand cylinders? The no-name brand ones have a massively high failure rate.

Clutch
Don't you People Sleep??

Lookit the time of posts.
As for your G/B or Clutch problem
have you tried Double Shuffling from 3rd to 2nd
see what results you get,may also be a G/B problem
or try
but first chock the wheels
pump up the clutch and use a suitable item to lock the
pedal to the floor
then look go under and slowly open slave Cyl Bleeder
see if any air comes out
it may be sucking air back in on the return
Worth a try before you go back and tell them to fix it properly with genuine parts.
they've probably charged you genuine prices for Luckychickenfoot Parts.
cheers

If they are branded parts, they should have the brand name cast into the cylinders. If you see "Girling", it is positive sign...

Very tricky to bleed these things. Take it back and and ask nicely if they could have another go at bleeding it.

Dear All
I have just flushed a bottle of fluid through the system. It might just have done the trick. Lessons learned:
1. Have a little faith.
2. Use OEM parts.
3. Go for the simple solution first.
I'll keep a close eye on things and the first signs of trouble will win Daisy a new master and slave cylinder.
Many thanks for all the advice - much appreciated.

My previous experience with an old rangie was to undo the clips holding the lines to the fire wall and dip bellow hieght of the reservoir, I spent hours before this trying to get a clutch and this helped to remove the air lock, I think I jacked up one side of the car too. Hope this helps you might have an airlock some where

One master cylinder, one slave cylinder, how could it get so complicated. I've now got 2nd gear from 3rd and the clutch disengages properly in reverse. I do now have a hint of a crunch when engaging 4th(!).
Unclipping the pipe from the bulkhead is new on me but I'll give it a look at the weekend.
Meanwhile I had an interesting conversation with a transmission shop. They have been having difficulties with TD5 clutches it is thought because later master cylinders had slightly narrower bores to make the clutch softer at the expense of slave cylinder piston travel. The solution being to get hold of 'new old' stock.
Finally (for now) there is also the school of thought that simply letting the car stand will allow the bubbles to float up and out of the system. Well I cycle to work in the week so Daisy is all tucked up until Friday!
