Having spend some time in fairly intense conversation with the underside of
the 59 TR3, particularly in the area of the clutch slave, I had a couple of
questions.
1. There are only 2 slaves used throughout the TR2 through TR 4A production,
the early, short Lockheed unit and the later and more plentiful Girling
#313440. Correct?
2. Whatever I can find showing illustration of installation shows the early
slave mounted through the support bracket on the back side (back of car) of
the bracket and the Girling unit bolting on the front of the bracket. The
bracket appears to be the same and attaches to the trany the same. Correct?
3. Is the stay rod for the purpose of supporting the bracket and preventing
it breaking out at the aluminum bellhousing only or might it serve as an
adjustment possibility on the alignment of the Girling unit?
4. There are 3 holes on the clutch operating shaft actuating lever into
which the fork end of the slave push rod might attach. Is it the opinion of
anyone that these holes are for possible adjustment of alignment of the
slave?
The failed slave I removed had worn extensively on one side of the bore due
to a severe misalignment of the centerline of the push rod and the piston.
On reinstallation I attempted to correct this. The supporting bracket is
not bent and the attachment points at the bell housing are ok. The tranny is
rebuilt with a new clutch operating shaft. I ended up shimming out one of
the mounting bolts on the barrel of the cylinder to correct the misalignment.
I tried fooling with the stayrod but it had little effect due to the
rigidity of the bracket, besides it moved the slave in only one direction,
the wrong one.. The only hole which the pushrod even approached alignment
was the bottom hole of the three holes on the actuating rod.
Anyone have any info or relevant experience on the alignment of the slave to
the clutch operating fork? Seems like there ought to be a better way than
shimming, but I can't determine what.
