Last time I replaced a clutch one of the disk springs (dampers?) was
broken and, yes, this caused some judder.<br>
<br>
Glad you got your problems worked-out, Simon. I admire your
tenacity.<br>

<p class="MsoNormal">Simon, so glad the clutch issue is behind
you. You may recall from my clutch saga a few years ago that
the replacement parts I received were the issue, although in
my case it was the clutch disc. So I think we must all be
wary of replacement clutches – measure everything and compare
old to new. I am told there are companies that will re-face a
pressure plate. Perhaps this is a better option, although on
a high mileage item, weakened springs may be an issue. I have
never run across that myself.<o:p></o:p></p>

<p class="MsoNormal">So just get in and drive it!<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-GB">I received a lot of help
and advice with regard to the clutch problem on my MkII BT7
for which, again, many thanks.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Here’s where we are:-<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">2) I bled the system
more times than I’ve hot dinners, as they say. No change.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">It was indeed the
culprit. Restoring the old cover cured the problem 100%.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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…..<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">However, new clutch
feels better than the old which is good.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">7) The supplier refunded
me in full thus let me keep the plate and bearing for free
which was some compensation.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Lightened flywheel by
14.5% off. Gives a nice feel. Not a huge difference but more
responsive. I’m pleased with it.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The overdrive pressure
issue was solved by an uprated accumulator and other related
bits.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">And it works!<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">What next?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Simon<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
