Clutch push rod

Hi Ian,

I spotted a description for clutch push rod length for a '54 laydown box is 7 3/4"

It is with some very nice clutch setup tips as well.

Hi Steve I bought new pushrod from NOCS at7.25 inch ,am going to try 7.3/4 in silver steel(do I need too harden the ends.excuse my ignorance?).going to put new plates in also.thanks for your reply,read the tips,very interesting.Ian.

Mine was one of the postings in the link shown above about the length of the push rod in the laid down gearbox and the anomalies of the various lengths mentioned. At the time I received not a single response to this so I used a trial and error method with 1/4" silver steel rod, hardened at the ends, and found that 7?" seemed to give the best result, although mine were not new plates. Another query I raised at the time, but again received no response to, was whether there should be a 1/4" ball between the pushrod and the mushroom stem. The parts list does not mention one although the rotational nature of the worm gear clutch actuator would suggest a need for one. This would also account for the 1/4" discrepancy between the lengths of a new 7?" rod from the NOCS and the 7?" length I found to work OK.

A more expert opinion appreciated.
