He suggested putting a return spring from the slave cylinder to the clutch fork, but I thought that would increase pedal travel too much as the cylinder push rod would have to travel farther to overcome the larger gap between the bearing and the clutch cover. Note this is theoretical, I decided not to do it; we reused a graphite bearing with over 100K miles as it had plenty 'meat' on it (but I'm in the habit of putting the gearbox in neutral at every stop--the downside being possibly greater wear on the pilot bush and input shaft)<br></div><div><br></div><div>The roller release bearing can be found here:<br></div><div><br></div><div><a href="https://www.ahspares.co.uk/austin-healey/performance-parts/Clutch/RELEASE-BEARING-BALL-RACE.aspx">https://www.ahspares.co.uk/austin-healey/performance-parts/Clutch/RELEASE-BEARING-BALL-RACE.aspx</a></div><div><br></div><div>Cheers,<br></div><div>Bob<br></div><div><br></div><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><b>From: </b>"Brian Drab" <bgdrab@eastlink.ca><br><b>To: </b>"Oudesluys" <coudesluijs@chello.nl>, "healeys" <healeys@autox.team.net><br><b>Sent: </b>Sunday, December 11, 2016 9:14:27 PM<br><b>Subject: </b>Re: [Healeys] Clutch-related noise<br><div><br></div><style><!--

On a BJ8, these have a solid carbon contact surface and do not move other than in or out depending on the pedal motion. I literally just replaced that bearing on a BJ8. I do realize that there is much more expensive throw out bearing that does utilize ball or roller bearings but I have never actually seen one of these. </span></p><p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:windowtext;mso-fareast-language:EN-US">I know of no way to increase the pedal travel on a BJ8. The pedal to master cylinder is non adjustable and the slave cylinder to clutch is also non adjustable. </span></p><p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:windowtext;mso-fareast-language:EN-US">When I mentioned, in an earlier post, the input shaft bearing of the transmission - this shaft is at engine speed with the clutch released, and motionless when the clutch pedal is depressed, which allows one to select gears without grinding them. Road speed has no influence on the transmission input shaft. I had exactly this problem on a vehicle (not a Healey) and that was the problem and was solved by replacing that bearing. </span></p><p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:windowtext;mso-fareast-language:EN-US">I certainly don’t know if that is the problem in this case but, to me, it is the only logical thing that is moving at engine speed (not road speed) with the clutch released and the only thing that would be motionless (relatively speaking) when the clutch pedal is depressed.</span></p><p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:windowtext;mso-fareast-language:EN-US">Brian Drab</span></p><br style="font-family:"Comic Sans MS";color:windowtext;mso-fareast-language:EN-US"></div><div><br></div></div><div><br></div></div></body></html>
