Couldn't wait. Out and Under... Being retired has its benefits.
I have the original Mark 2 push rod and the new adjustable one I bought from
Rick.
THEY ARE NOT THE SAME LENGTH. The Mark 1 Adjustable push rod is 4 1/4" long
fully extended; the original Mark 2 push rod is fixed at 4 3/4" long. The
half-inch apparently matters.
The parts catalog lists two part numbers for the push rod: 6100278 for the
Mark 1 and 6100856 for the Mark 2. Of course they don't say what the
difference is, but - assuming my old rod is the original - we know: 1/2" in
length. Rick only lists one part number for the push rod, it's the
adjustable Mark 1 push rod. There is only one part number for the slave
cylinder in the parts catalog.
The first item in C.A.T. Service Notes (P. D-1) says don't adjust the rod
anyway. It's dated 1965; apparently they fixed the length in the Mark 2.
The slave bracket mounts on the transmission side of the bell housing.
There's only one way to put it in; two bolts on the side, one on the bottom.
That puts it closest to the pivot arm. The slave mounts to the engine side
of the bracket. It'll only go in one way also.
