Clutch and cambelt change

[geoff]

1/ Btw what is the reason the old clutch gets so heavy?

2/ I sprayed lubricating oil to the clutch fork and bearing area and it made it a little bit easier but the clutch cable eventually went again.

3/ Is that the pressure plate gets somewhat hardened due to all the heat etc during its hard life.

1/ Difficult to say exactly

2/ Lubricating worth doing !  Also lube the cable, worth considering a rerouting of the cable.

3/ Doubt it

Look at this topic for some good information .. https://www.berlingoforum.com/thread-164...plasticine

Also.. something I wrote on another topic that may be of interest ... 

"make a small well around the shaft at the top using plasticine and fill the well with oil. As the clutch is operated the oil will run down the shaft and reach the bottom bush making the operation lighter.
Later type actuators at the front of the gearbox work differently so this fix doesn't work then.
I am an advocate of lubricating the cable with oil - it removes easily - and I use black moly-grease on the auto adjuster. Worked for me and no issues with it over many 1,000's of miles.
Also when you look at the cable routing it couldn't be more convoluted, I rerouted mine for the smoothest single curve possible - top of and around the engine bay / wing area. Rerouting makes a big difference.
I have to say that it will never be as light as a hydraulic clutch but it doesn't have to be hernia inducing with a cable either. My last vehicle was transformed by doing this mod.
edit : there is no chance of the clutch plate getting contaminated with my plasticine trick."
