[Healeys] Clutch Slave push rod problem

[Al Fuller]

Hi Phil:
  
 You don't mention the reason for having to replace the clutch master and 
slave cylinders, so my answer below does not take into account any 
interaction between what may have caused that and your rod length 
dilemma...
  
 All that said, if it ran 25 years for you with the nut making the clutch 
rod longer, what is stopping you from just putting it back like it was and 
driving another 25 years!?!

Subject: [Healeys] Clutch Slave push rod problem   
 Hi all, 
  
 Last week  a friend and myself  installed a new clutch master cylinder and 
slave cylinder on my 1961 Austin Healey 3000 BT7. On removing the slave we 
noticed that a small nut had been put on to the end of the slave cylinder 
push rod by a previous owner (I have owned that car for 25 years so it was 
some time ago!).

Why we wondered?

We put on the new slave (without the nut) and bled the system. Low and 
behold without the nut we where unable to engage gear as there was very 
little movement on the clutch pedal. Realizing that the the nut had been 
put there for a reason we removed the push rod from the slave and replaced 
the nut (1/4 " in width) and hey presto we then got more movement on the 
pedal and could engae all the gears. the push rod appeared to be a standard 
size.
  
  I have now got a extended push rod, but as its 14mm longer than the 
standard one it may not work.

Does anybody know whats going on? We assume that the real problem lies 
inside the gear box. What would be a better solution (without going inside 
the box)?

Any help welcome.

Phil
