Help.. Is it a Clutch or Gear box problem ? - Land Rovers Only

starblaze61 · 06-04-2007, 01:16 PM

Hi all , UK Landy lover Here
I have an old 1972 SWB series 2a / 3 Landy , which I love to bits.
The problem is while driving it the other week as I doubled the clutch the pedal hit the floor with a clunk and stayed there , so I pulled over and I flicked the pedal back up but now the pedal has next to no travel and I am unsure what maybe wrong ... Clutch or Gear box ?

Someone said maybe the master cylinder or the ? Rod to the box .
If you look in the engine bay and someone pushes the clutch pedal all the linkage moves very slightly .
I hope someone can help me with an idea or two .
Thanks a lot
Su

Probably either your master cylinder has failed..... less likely your slave cylinder at the box has failed... even less likely the rod that goes from the slave to clutch in the box has snapped.... I would check the master first....

Thankyou for the reply .. will check the master hopefully tomorrow.

IF and I hope its not the Rod you mention ... is it a very big job to do ?

Thx again for the help

If it is the rod, then it is a pull the tranny job. It is not a complicated job, but will take some time. All the floor boards have to be removed, drop drive shafts, remove hand brake..... I can pull my tranny do about 3 hours of work on it, and have it back in a longer day.....

Had the same problem with my 109. Sounds like a hydrolic problem. Most likely a MAster or slave problem. Not a big issue as they are both inexspensive to repair.

The problem will not be with the gearbox, as the clutch, and transmission are really two seperate system, albeit clutch disc drives the gearbox.

There are supposed to be two springs, attatched at one end to the pedal stock, and onto the bulkhead, top side of the footwell. Since the pedal didn't come back up, for starters, those springs are probably gone and you never noticed as the pressure plate was pusing the slave cylinder back, slave pushes the fluid back to the master, and master cylinder piston, in turn, pushes the pedal stock back up. A ruptured flex line, between the slave and the steel line going from the master, could have caused the problem. A mechanical failure of the pushrods, either on the MC end or slave end is pretty remote.
First thing you should have checked was to see if all the fluid in the MC had drained out. That will give you a pretty strong lead as to where to look next.

Also don't forget to check the lines for leaks. I got a pinhole in a line once and had no pedal.

I just fixed a similar problem on my Series 3. Mine was a bad clutch slave cylinder. Being so close to the exhaust, it would fail to retract when it got warm. I would push the pedal down, it will extend then the pedal spring pulls the pedal back up but the slave cylinder rod remains extended and the next push will just push the slave rod a little bit until it tops out. The pedal felt like it hit something solid about an inch down. I would have to wait until it cools off a bit before it would release and work again. When I took it out, it was in bad shape. It had a lot of rust on the inside. Swapped in a new slave cylinder and all is well now.

Not so fast. This might not be correct. The question is about a 1972 IIa/III.
So the question now is- What gearbox is in it? If it is a IIa gearbox (and clutch) there is no need to start pulling trannies.

As mentioned, check fluid level, check for leaks, return springs and linkages.

Notice that the Rod is the even less likely, and the master cylinder was most likely..... He had asked how hard it was if it was the Rod...
