Or are you asking before putting it all back together to make sure you’ve covered all the bases?</div><div>Normally a grabby clutch is due to the friction surface (interface between the disc and pressure plate/flywheel) and lack of compliance in the clutch disc itself. In your case I would look for a crack in the pressure plate and the flywheel friction surface. You might want to have a cut taken off the flywheel surface to be sure there are no irregularities or build up of glaze. You’ve already done this on one side with a new pressure plate.</div><div>I would not stop the throwout bearing sleeve from spinning. It should have no effect on this problem one way or the other. Being brass, if constrained it will wear in one spot where the fork interfaces with it. Might be doing that anyways.</div><div>Good luck!</div><div>Phil Gott<br><br><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Apr 22, 2020, at 5:59 AM, David Gott via Fot <fot@autox.team.net> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><!--[if gte mso 9]><xml><o:OfficeDocumentSettings><o:AllowPNG/><o:PixelsPerInch>96</o:PixelsPerInch></o:OfficeDocumentSettings></xml><![endif]-->
Hi Nick,<div><br></div><div>The way I see it there’s only a couple of variables left. Which hole is your slave attached to on the clutch fork? Does it make a difference if you move it to the “furthest out” hole? </div><div><br></div><div>How is the surface of the flywheel? I’m sure you checked it out changing all those parts. Maybe it’s burred and causing the clutch to grab? Did you scuff it down a bit? </div><div><br></div><div>Here’s the long shot. What about the crankshaft thrust washers, is there all of a sudden too much play, like a thrust bearing fell out? Maybe it’s changing the way the clutch slave interacts with the pressure plate.</div><div><br></div><div>That’s all I got!</div><div><br></div><div>Dave Gott</div><div><br><br><br><a href="https://overview.mail.yahoo.com/?.src=iOS">Sent from Yahoo Mail for iPhone</a><br><br><p class="yahoo-quoted-begin" style="font-size: 15px; color: #715FFA; padding-top: 15px; margin-top: 0">On Wednesday, April 22, 2020, 5:08 AM, van.mulders.marcel--- via Fot <fot@autox.team.net> wrote:</p><blockquote class="iosymail"><div id="yiv5972241541"><div><div style="font-family:Verdana, Arial, Helvetica, sans-serif;font-size:10pt;color:#000000;"><div><br></div><div><br></div><hr id="yiv5972241541zwchr"><div><b>Van: </b>"van mulders marcel" <van.mulders.marcel@telenet.be><br><b>Aan: </b>"Nick Black" <vintagenick42@yahoo.com><br><b>Verzonden: </b>Woensdag 22 april 2020 11:07:28<br><b>Onderwerp: </b>Re: [Fot] Its Opinion Tyme Again...<br></div><div><br></div><div><div style="font-family:'verdana' , 'arial' , 'helvetica' , sans-serif;font-size:10pt;color:#000000;"><div>Very weird that changing all those parts has no effect.

It suddenly started acting like an off/on switch with no chance of slippage to get goin. The engagement was so sudden that it broke a side gear in the locker. Upon review everything appeared well within spec. I changed the clutch disc. transmission input shaft and changed the throwout bearing sleeve. No dice...same issue.</div><div dir="ltr">Got it apart again and have changed everything...disc, pressure plate, bearing, crankshaft bush, cross shaft bushings, clutch hose, clutch slave cylinder and clutch master cylinder...pedal assembly seems smooth without any binding.
