<div dir="ltr">The original post was about a Toyota 5spd conversion. One has to make a new fulcrum bolt for the clutch arm to rotate on and the length of this bolt effects the length of the arm's movement. It is possible to adjust the throw out bearing's movement on or off the clutch plate. <div><img src="cid:ii_159139627ec8e71f" alt="Inline image 1" width="471" height="346"><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr">Ira Erbs<div>Portland,OR</div><div><span style="font-family:'Times New Roman',serif"> _______ _______</span><br style="font-family:'Times New Roman',serif"><span style="font-family:'Times New Roman',serif"> (______ \____1959 BN4____/ _______)</span><br style="font-family:'Times New Roman',serif"><span style="font-family:'Times New Roman',serif"> (_________________________)</span></div><div> BT7 engine and disk brakes</div><div><br></div><div><span style="color:rgb(51,51,51);font-family:"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:14px">A racing car is an animal with a thousand adjustments.

<div class="m_-8503602604804219024moz-cite-prefix">There must be some way to adjust. Often
the rod can be lengthened/shortened by adjusting a nut, the slave
cylinder perhaps can be moved forwards/backwards, shimming etc. I
presume the return spring in the slave cylinder is strong enough
to push back the piston.<br>
Excessive wear on the clutch cover can be caused when the bearing
is just touching the fingers, but not enough to spin the bearing
at the same speed, and/or by a foot resting lightly on the clutch
pedal.<br>
With the clutch pedal released a clutch roller/ball bearing should
not spin.<br>

roller/ball clutch release bearing are of this this
construction. It is slight and when they have gone to far the
rest of the part is worn as well. Anyway, considerable wear on
the clutch cover fingers indicates to little clearance and
proper adjustment of the clutch is at hand.<br>

<p dir="auto">Based upon my experience with the TR6 clutch,
which uses that system, I would be reluctant to make the
change. They have a habit of wearing away the "fingers" of
the clutch diaphragm.<br>
I have found that the most common cause of carbon release
bearing failure is a lengthened slave cylinder push rod
which causes the bearing to be in continuious heavy contact
with the pressure plate "platen" at all times. Furthermore
the pressure rises as the clutch dics wears which exuberates
(my $10 word of the day) the situation. <br>
There MUST ALWAYS be free play at the clutch slave cylinder
push rod when the clutch pedal is not depressed.<br>
