Thread: Clutch Master cylinder gone?

    Clutch Master cylinder gone?

    Got into the TD5 Deefer today, and the clutch pedal almost touched the floor before I could engage. Sure enough, no fluid in the master unit, and a pool of fluid under the clutch pedal. Not a good sign! I picked up a new unit from the local land rover spares guy, but he cant fit it for a month . Before I find someone else to fit it, is it an easy job? It seems like unbolt the old one, fit a new rubber on it, bolt on new one, top up fluid, and pump pedal to get air out? Is it that simple, or is there something else I should know?

    Its about that simple - do a search on here as there have been a few threads on the subject.
    The only catches are that some of the bolts are rather hard to get to, and you need proper pipe nut spanners for the pipe unions. I have not done a TD5, but all the others I have done (110, S2a, S3) are a lot easier to remove the whole pedal assembly after undoing the pipes (six bolts with captive nuts). Fold the bonnet right back or remove it to make life easier. Last one I did took about three hours all up, including repainting the pedal bracket.

    That is essentially the case, but it is a fiddly bugger of a job. Our techs (experienced) can take an hour or more to do it. How handy are you with a spanner?

    this is spooky, just got back from Brissy and noticed a few drops on the floor mat coming off the clutch pedal.As I plan to leave on a 5000km trip Saturday morning and I have no way of getting a spare between now and then, should I panic or just keep an eye on the level, and top up as necessary???Do they just let go or can you nurse it along??

    Can't comment for TD5 but can for 300Tdi which I presume is the same or at worst very similar...

    I've changed the master several times

    * Take off bonnet
    * Unscrew rectangular plate on top of clutch tower
    * Unscrew push rod and retaining nuts bolts (can be fiddly)
    * Fit new MC (reverse of opposite)
    * Bleed

    Personally, the most frustrating part for me has been the bleed. Last time it was a 3 person job (pedal pumper, reservoir filler, bleed nipple operator) but a brake bleeding kit could reduce the people needed.

    I'd allow less than an hour to do the MC changeover. Add bleeding to that.

    On the Tdi, apparently the clutch pedal should be about an inch below the brake pedal at rest. Any higher and the plunger in the MC can over centre an prematurely wear the seal out. My mechanic told me this after mine failed after 6 months.

    Thanks guys - handy with a spanner? Do all servicing myself, and would rate myself a competent amateur . However, no pipe spanners, so I think that this time I will drive it down to Len's Landrovers, who said he could do it this afternoon.

    If I wasn't so busy this weekend, I would have got the spanners and tackled it this myself. Thanks for all the fantastic replies!!

    Just dropped it off - they have a nice 62 early series II in for renovation. It was in vietnam, and they tried to convince me that the work on the side was fixing bullet holes . Good lads, and obviously know there stuff..

    You can manage without pipe spanners if you have to. I replaced the clutch MC in mine in a campground in the Barossa recently. Took 30 mins from start to finish with minimal tools. I surprised myself!!!

    The only real bugger is access to the bottom bolt.

    That's why I find it easier to remove the whole pedal assembly - you can pull it out and reinstall it in a lot less time than messing about with that bottom bolt! (and a lot less skin off too). Whether you can do it without pipe spanners depends on how easy it is to move the unions, which largely depends on how long since it was last done, and how much salt water has got on it in the meantime.
