Stiff clutch pedal
Posted: Tue Jul 30, 2013 11:09 pm
My 1970 Traveller's now about 90% reassembled and drives in and out of the 'nigel farage'. However the clutch pedal's much stiffer than I'd expect.
When fitting the recon engine and original box I narrowly decided against replacing the clutch, as wear was visible on the plates but they looked still serviceable for some time to come. The car had been off road for the previous 20 or so years.
Since then I've fitted a new clutch pedal to replace the worn original, complete with new pivot bushes. Also I've replaced the bushes either side of the relay shaft mechanism. Yet the clutch pedal still needs about two or three times as much foot pressure of a modern car's. I don't know if Minor clutches tend to be stiff or not, but my 1950s Rover pedal isn't stiff like this.
The pedal doesn't initially feel stiff for the first 3 inches or so; resistance only begins as the arm on the side of the gearbox passes beyond a certain point. If the arm's disconnected from the mechanism, the pedal moves freely. Therefore I suspect the problem is with the clutch itself or the way I assembled it, not the mechanism on the outside of the box.
I've always understood that the forks of worn clutch plates offer less resistance, not more. Many years ago a chap showed me old versus new plates on a Cortina clutch he was changing, and how much easier it was to deflect the sprung sections on the worn one.
Any suggestions, other than fitting a new 3-piece clutch kit to see if this solves the problem?
