It could very well have been damaged during installation at the factory. I never took it apart before installing it so don’t know. Nothing jagged at the end of the bore (but there was an issue down there). Yes, the peddle hits the floor before the piston bottoms out. And I do have the spacer installed. The part of the seal that touches the very end of the bore is the flat end lip of the seal, it goes up against the recuperation hole and keeps fluid from going up into the reservoir when the peddle is pushed in and forcing all the fluid to the slave cylinder.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'>Here is what I “think” the issue was; At the very bottom of the bore where the recuperation hole is, there “was” an area that wasn’t machined deep enough to have clean machining all the way around the hole. An area just about the size of the inner part of the seal hadn’t been machined, it was a few thousands lower than the machining around the outside (a slight pocket if you will). That, I think, caused the rubber seal to “buckle under” with the very high pressure (could be over 1000psi). If you have seen my video of the overhaul of the brake booster you can see at the end of the video where I put pressure gauges on the brake output and you can see the pressure of 1500lbs from the brake master cylinder (same principle as the clutch master). <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'>What I did was to “grind” the bottom of the bore with a wood dowel that I put some sand paper on the end and spun it to take the higher area around the hole down to the hole, only a few thousands of an inch, now the seal has a flat surface to seal against. So far its working, but we’ll see.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'>Coolvt, how in the world did you have this problem for so long??<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'>Jerry Christopherson<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'>9473187<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'>TAC Insp. #58<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Tigers [mailto:tigers-bounces@autox.team.net] <b>On Behalf Of </b>Gary<br><b>Sent:</b> Thursday, July 15, 2021 4:38 PM<br><b>To:</b> tigers@autox.team.net<br><b>Subject:</b> Re: [Tigers] Clutch issue<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:12.0pt'>It looks like it was damaged when it was installed.<br>Where it is broken should not be touching anything, no?

Gary was the only one curious enough with some guesses. The problem was the seal inside the clutch master cylinder, the one that covers the recuperation hole in the very end of the cylinder bore (#4 in the blow up of the clutch cylinder exploded view in the green manual). Somehow it had failed as you can see in the photograph. The question is how and why did it fail, I have some ideas, but won’t go into them now, but I think it had to do with the machining at the factory that caused it.
