Craig- I didn't have any trouble at all bleeding the line after the slave
was rebuilt. I also remember that there's a wrinkled sleeve inside of the
throw-out arm that keeps the arm from torquing under load, it's kind of like
a cylindrical wave washer, that holds the pivot pin in the arm. If this was
worn, the aluminum arm
can wear out also. Another thought, we lost the clutch at the beginning of
last season after only about 2 1/2 hours of running- due to using a sintered
bronze clutch disc (too high-tech for an LBC). When we got a replacement kit
(disc, pressure plate, and T/O bearing) and assembled it, the clutch was
IMPOSSIBLE to depress- the kit was unusable for a 1300. The store swore up
and down it was right, and we must have installed it incorrectly. The
problem was that the friction surface of the pressure plate was too thick-
it wouldn't let the disc free under any circumstances. To make a long story
longer, sometimes no matter how well you do your work, as long as you trust
vendors to give you the correct parts, you're at their mercy.- I know this
is no consolation, but let me know how it works out, and if you want to know
where we finally found the correct parts, just ask.
