Not sure whats happened to clutch/gearbox


Recommended Posts

Hello. Whilst driving the yesterday, I was shifting into 3rd when all of a sudden my clutch peddle went completely wobbly! There is no resistance to it at all. I was not far from a town so I thought I would shift through the gears whilst trying to time it. Anyway, I had not driven without a clutch before, and my timing was carp! :unsure: Which unfortunately lead onto the next problem; So I shifting , without the clutch, coming up to a junction going down through the gears, Im getting a bit panicked (and very pi**ed off) when just like the clutch peddle my gear stick just goes totally wobbly (I was being forceful), just wobbling around all over the place! So Iv got a wobbly clutch peddle and a wobbly gear stick, I cant engage any gears what so ever (fortunately the landy is in neutral...Im assuming as it rolls freely :huh: ). So I got out recovery and got towed to my garage. Before this I was having no problems with shifting through the gears at all, 3rd has always been a bit stiff, but it has been like that since I bought it almost a year ago. I have serviced it regularly and the oils have always been clean, like I said there was no warning, one moment I was happly driving along (I may even have been singing along in the car! :rolleyes: ), the next moment no clutch! And so on. Im just wondering if you guys have a prognosis of what you think could have happened, and perhaps an idea of how much you prognosis would cost to fix (thats the worrying part! :( (my garage is cheep on labor, bonus). Cheers for any impute :(

Could be the master cylinder. Is there any fluid dripping down the clutch pedal?

Something similar happened to me, but there was no doubt as to what occurred as the seals on the master cylinder had failed big time and I was sitting in a pool of hydraulic fluid!

Broke the gear selector on my 110, could move gear stick but just stayed in same gear. Was in France at time and local garage fixed it for £50! Have also had master cylinder suddenly fail (clutch goes straight to floor with no resistance) and then start working again? Changed it anyway at first opportunity.

Hey, no fluid dripping that I have seen, and I had a good look. Yeah Mark, sounds the same, it totally went, came back a wee bit, but I only had an inch or so of peddle working, then went completely I think I will be living in hope that it gets fixed for £50 though!

Cheers

perhaps the pushrod has broken through the operating fork, does the pedal move up/down or is it jammed down ?

& the gearlever there's a cup at the bottom end which is secured by a grubscrew could be this screw has worked loose,

It is likely that either your Master or Slave cylinder has let go the internal seal could have given out but the dust cover is keeping in the fluid, or its already gone onto the floor. check your fluid level and see if there is any left. You Should replace both cylinders as most people will tell you that if you only change one the other one will only let go...

As for your gear selector it is likely that the ball joint at the bottom has broken off with the force, this is a really easy fix (if it is just that) replace it with a new/previously enjoyed one you can pick one up from a scrap yard/ebay for a few pounds easiest way to check this is to lift up the gaiter you should be able to see the top of the gear box and the gear selector top. It is probably that it is broken below the mounting bracket this is removed by four bolts.

Yeah Western, the pedal is moving up and down, the recovery guy said the same thing about the pushrod, is that a big/expensive job to fix? Im not so sure about the screw coming loose, as the gearlever was the same as it has always been, it just seemed to go loose/wobbly all of a sudden, I think I have broken something there as I was forcing it.

Cheers Jason, that could be likely with the dust cover holding the fluid back, as a little fluid had gone, but it was only noticeable once I removed the cap to check the level. Fingers crossed for the gearlever being an easy fix.

The guy who is working on the landy is a good bloke, plus its been a hobby of his doing up old landys so Im not worried about being stitched up or anything, the main worry is the cost of the fix, but so long as the gear box is sound it shouldn't be too bad Im guessing? Having said that I don't know how hard/easy it is to do any of the fixes mentioned above :blink:

Cheers a lot ;)

Clutch pedal usually goes solid if the fork has punched through. 300Tdi clutch pedal will saty down when pressed, so has to be hooked up (it 'goes over' the return spring). 200TDi is normal and will return from the floor on the spring, but will still go solid on a second press of the pedal. On a rare occasion the guts of the slave will go into the bell housing and the pedal will always be floppy. In this scenario the fluid will immediately drain out of the master and come out of the drain plug. Check the master cylinder reservoir for fluid and top it up if necessary. Repeated pressing of the pedal may well restore clutch action for at least a short time - where any leaks (and the location of them), will tell you the problem. If no leaks, then clamp the flexible part of the clutch pipe with a brake pipe clamp or the careful use of mole grips, then press the pedal. If the pedal is solid, then the master and pedal assembly are fine, so slave, fork, or clutch itself is the problem.
