[Healeys] Update on clutch woes

[gradea1 at charter.net]

Hi Simon-hope your blood pressure has come down. Yea, parts are parts,
but the correct ones are most important. Additionally, anyone mucking
with the OD, that doesn't know what they are doing, is trouble. Glad
you are up and running-such a fine Healey it is. Enjoy your manual
shifts! Hank

Subject: [Healeys] Update on clutch woes

	I received a lot of help and advice with regard to the clutch problem
on my MkII BT7 for which, again, many thanks. 

	Here’s where we are:- 

	1) I replaced both master and slave cylinders and even converted the
former to having an adjustable push rod which, mercifully, I did not
have to use. No change. 

	2) I bled the system more times than I’ve hot dinners, as they say.
No change. 

	3) I had the gearbox out and back 3 - or was it 4? – times.
Centring that thing to a nanomillimetere if there is such a thing. No
change except to blood pressure. 

	4) I had fairly fruitless discussions with the supplier who assured
me that “Nothing like this has happened before”. No comment will
be issued at this juncture as the lawyers say. 

	5) I gave up on the new kit and decided that the new clutch cover,
being 10+mm higher in the centre than the old, was the likely culprit.


	It was indeed the culprit. Restoring the old cover cured the problem
100%. 

	6) I’d only swapped the clutch in the first place because I had to
remove the gearbox for an overdrive issue. On inspection the old
clutch parts looked pretty good and, while you’re in there….. 

	However, new clutch feels better than the old which is good. 

	7) The supplier refunded me in full thus let me keep the plate and
bearing for free which was some compensation. 

	Lightened flywheel by 14.5% off. Gives a nice feel. Not a huge
difference but more responsive. I’m pleased with it. 

	The overdrive pressure issue was solved by an uprated accumulator and
other related bits. 

	You may recall that the pump would not go back in, despite my best
efforts? I thought I must be doing something wrong but gave up in the
end and drove the OD and box up to OD Spares. Dave put in a new front
casing as someone – NOT me – had used some “Plastic Padding”
(JB Weld?) in the area at the top of the pump’s travel. I presume to
reline a scored bore. Anyhow, somehow or other, that stuff prevented
my getting the pump back up the last few mm. So, in effect, that half
of the OD has been rebuilt. 

	And it works! 

	I’d not had the car on the road until yesterday as I’d been
waiting for the return of my handbrake from the platers. That’s back
in and looks much better than before. I even managed to adjust the
handbrake cable as, miraculously, it was all greased and nothing was
jammed on the threaded rod. 

	What next? 

	Simon
