G'day down on West Island Peter,
You may not need a new angle drive. One of the components of the angle
drive is a short piece of squared speedo inner cable (the input shaft)
pressed inside a gear shaft. Often the fit is not quite tight enough and
the piece of cable starts to pin inside the shaft.
You can test for this by holding the female (driven) shaft with a small
screwdriver and then trying to turn the input shaft. There should be no
slippage.
You have to tap the input shaft inward, to push off the larger frost
plug to disassemble the thing and then you can clean the oil out between
the piece of speedo cable and the hole, into which it is pressed, by
washing thoroughly with brake clean.
I then dribble in a little red Locktite, leave it over night to harden
pop it all back together and Bob's your uncle.
I actually have one sitting on my desk awaiting this attention as I
write this.

G'day listers
I'm in the middle of a cumulative disaster (not uncommon for me) -
started
with having the speedo recalibrated to suit the 3.54 diff. Speedo shop
said it
looked like the cable was too long and causing problems at the speedo
head.
Took 1/8in off gearbox end - no difference. Proved to be the square
section
was too big to go into angle drive. Shaved this but then no drive at
all.
Assumed too much taken off so ordered new one from Healey Factory. When
it
arrived it proved the wrong one - small nut on gearbox end. Discover
that
although I have a BN1 3 speed, the angle drive's a BN2 (large knurled
nut)
Returned this only to get similar but slightly longer one in return -
this
time Healey Factory's mistake, & no BN2 ones in stock. Managed to get a
new
inner cable made locally, installed and all appeared OK, but - still no
drive.
Checked visually that angle drive turning, but, when cable inserted, no
drive.
I assume non-meshing or stripped gear in angle drive.
Can anyone give me any guidance here? Are these angle drives susceptible
to
failure? Are there any "whatever you do don't...." 's? (If so, I've
probably
done it!)
I have a replacement angle drive on order (A$120.00) but I wonder if
again I'm
barking up the wrong tree.

PS How does the angle drive detach from the overdrive?
