"Bedford crash gearbox techniques" - Shows a certain age!!!

I had my slave clutch cylinder out a while ago, and was amazed at the crud in it in a 4 year old car. I cleaned it all out, flexed the seal a bit between my fingers, put it all back again, and it worked fine. While I was at it, I replaced the rigid steel bundy tubing, the rubbish "brake" flexible, and replaced the lot with SS Goodrich flex. Lubricated the release bearing rod as best as possible as well.

You had seen this, did you ?

I had actually missed that page, hopefully I will get away with the repair kit apposed to the whole slave cylinder, once again many thanks dieter.

One possible cause of the slave cylinder failing is the siezing of the clutch lever as Jerry mentioned. Once you've removed the clevis pin that joins the slave cylinder arm to the clutch lever, see how easy it is to move the free end of the clutch lever to and fro - if it's in good order there should be nearly 1cm of almost resistanceless play, if it doesn't move at all then the lever shaft may be seizing in the gearbox casing - the Achilles heel of the PG1 gearbox. Getting oil or grease down the shaft isn't straightforward, but worth a go nonetheless - replacing the lever involves removal of the gearbox, which is about 8 hours labour...

Good luck!
