Td5 Clutch playing up.

[rijidij]

My clutch has been doing funny things the last week. It feels normal and operates normally most of the time, but occasionally the pedal has very short travel from fully depressed on the floor to when the clutch engages. My first thought is a leaky/worn seal in the master cylinder.
Just thought I'd get a second opinion from anyone who's had the same problem before I go pulling things apart.

Cheers, Murray

mmm dual mass flywheel

Could well be the master cylinder. They are hopeless. (same ones that have been fitted since about 1975)

Just change the complete thing. Not sure re-sealing it is worth bothering with.

As Psimpson says - it sounds like the master cylinder (which basically is unchanged since 1958 - just went to the one with a reservoir attached when dual circuit brakes were fitted). At the cost they are, replace the whole thing, but try to find a better quality one if possible. Note that they are the cylinder most commonly fitted to trailers with override hydraulic brakes, just have to fit the old pushrod. Since part of the problem with new ones may be that they have been in stock too long, getting one from a trailer supplies place that has a larger turnover than a Landrover parts place may be an advantage.

At least the fact that it is intermittent means it can't be the clutch fork pivot!

It is possible that it is low fluid - have you checked this? But that merely means you have to find out where the fluid went too - look on the floor under the mat! Other place it can go is into the flywheel housing via the leaking seal on the slave cylinder.

ive had 3 fitted under warrenty by LR all with in 26 000k's, ive since fitted an alko trailer one and have done 30 000k's....

the only difference between the LR ones and the trailer ones is the piston in the LR one is steel where as the trailer ones are alloy. so i put the leaking down to the rod pushing the piston (steel) onto the alloy bore and scratching it to death. alloy on alloy is much kinder

Ive had to change mine once so far. Its now just clocked over 62k miles, and I have just checked and the last one was fitted at 31,215 miles in December 04.

could be about time for another one!
