That's good info, I didn't have that before, did some more checking, came up with this below,
but if all I need is 0.035" to 0.045" movement at the release bearing, and I presently have
0.440" available at the release bearing before hitting the pressure plate with the clutch
release fork, it looks like I'm worrying about nothing. Plenty of clearance at the pressure
plate housing next to the clutch release fork with the bearing only moving max 0.045"...
And I need to rethink my hydraulic clutch release mechanism design!
I wrote this up before seeing your comment, it's interesting thinking, had fun doing it:
Took another look at the Tee Post mount, the fork, and the release bearing...
There is only 0.512" protruding out of the fork...
And those side rails on the mounting stand are 0.191" high,
that leaves 0.321" available to cut, but I also need to allow room
for the fork to rocker back and forth, how much do you suppose that is?
I tried to measure it, came up with about 0.025",
so that leaves only 0.296" max that can be cut !!
Had another thought though, let's check where the release bearing
sits on the tranny snout, I can measure that...
It turns out that the rear of the release bearing collar is
exactly flush with the rear edges of the bell housing...
That means that the rear of the release bearing is also flush with the front
edge of the tranny, so with a straight edge I was able to measure just how
much travel the release bearing had available, turns out is is exactly 1/2" !!
Using the same ratios that I used above, 0.55" movement at point "D"
gives 0.44" at point "A" (the release bearing), but we
want 0.50" movement at the release bearing (point "A")
which requires 0.62" of travel at the slave cylinder (point "D")
Since I already have 0.55" travel available at point "D", I just need to
add 0.07" to get 0.62" movement at "D", getting 0.50" at the release bearing.
In order to get this, I only need to trim the tee post by 0.030"
But I'd be touching the pressure plate housing, so I need to add
additional clearance for the pressure plate...
I ran the numbers several times, and came up with these results:
Trim the tee post 0.080" gives 0.070" clearance,
Trim the tee post 0.100" gives 0.100" clearance,
Trim the tee post 0.150" gives 0.170" clearance,
It looks like all of these trim options will not cause other problems,
taking into account the angular movement of the fork on the tee post,
the amount of post exposed under the fork, and the amount of the tee post
required to fit into that base mount on the tranny, I have about 0.296"
available for a maximum trim job before I might run into a functional interference.
So, the real question is, just how much clearance do I really
need for the pressure plate housing ??
My feeling at this point is to trim the tee post 0.100" and see if I can live
with 0.100" clearance at the pressure plate housing...
