Clutch rebuild

Hi,
I have a leaking clutch master cylinder and I am going to try and rebuild it.
I have the seal kit.
Has anyone done one before and any photos or advice?
It's for the later commer I think? 1972
Thanks
 
This is what it looks like in bits



The hardest part is getting the pin out of the end of the pedal/cylinder rod (and replacing it) The big return spring needs to be levered out of the way to get access to the pin, awkward but do-able, I think I used an open end spanner as a lever slipped in behind the spring to give me some room. Would also advise giving the assemble a blast with a pressure washer or air line to get rid of some of the grease and dirt that builds up so you can see what's what.

The van now drinks clutch fluid so I am hoping my diagnose is right and it needs a rebuild?

How successful was your rebuild?

I eventually fitted a new cylinder after about three years but it probably would have lasted longer. I changed it when I had issues after fitting a new clutch - changed master and slave but it eventually turned out to be a faulty new clutch plate:rolleyes:
Another tip is to give the seals a smear of red rubber grease on assembly to lubricate the cylinder bore.
 
With the time and effort involved in removing a cylinder to rebuild I also prefer to just put a new one in, much better long term.
 
I also just put a new one in along with a slave and had a new line made up. I didn't want to be faffing about with it more than I needed to.

The spring was a bit of a pain but nothing as annoying as the brake shoe spring pins to get in and twist.
 
Check the inside of the cylinder for any major scoring or pitting if you find any, i wouldnt even bother to rebuild it as it will probably leak again after a short while.
A new one is a quick and easy one time job..:)
