Hello all: I mic'd a couple of input shafts today to refresh my memory.
Here are the
Stock 'early' shaft at the seal area is .700"
Stock 'late' shaft at the seal area is .770"
Stock 'late' shaft below the seal area is .690"
With that in mind, is a mere .010" smaller enough to not allow the early
work on the late shaft? Probably a pair of them stacked anyway using the
new release bearing shafts. My idea of installing a third seal on the
the release bearing shaft may or may not be needed. Of course it would be
a pain to change that seal, the diff would have to be disassembled similar
the PG diffs.
There is also a reference by Steve Semon on the placement of the pilot
there is a possible problem with the bushing being too far out of the crank
similarly if the bushing is too far into the crank then the input shaft has
move back and forth.
Hope some of this helps.
