Hi Zeebee,
Sounds like you're making good progress on your GT!
I'd pull the clutch arm pivot pin, chuck the arm up in the vise and then use heat and a good penetrating fluid to loosen the adjuster up. A little anti-seize on the adjuster will help prevent future grunting.
Once that's done, you could pull the outer body of the throwout bearing out to have a look see. Might help to clean the t/o bearing bore a bit with "Scotchbrite" or similar and squirt the rubber o-ring seal liberally with silicone spray.
Reassemble everything and hook the cable up. Hand lever effort still too high? If the clutch is otherwise working okay, it could possibly loosen up with use. If the clutch doesn't disengage you may be able to hold the hand lever in (engine off) and roll the bike back and forth to break the plates loose. If not the trans will probably have to come out. Cheers,
Charlie.

| Well... we have vroom! I took the heads off the GT to check all was OK, and I'm glad I did. The bod what put the new barrels in a few years back must have been blind or something as he used the wrong bloody head gaskets! And he glued them down with something impressive. So after finally persuading the heads to come off by pretty much prying the headgaskets apart, I spent about 4 hours cleaning the incredibly lumpy gasket remains off. And whimpering about the definitely worn but still straight pushrods. The barrels were fine, no marks, no rust traces, nothing. So now it's all back, a new coil (GT40, which seems to work OK) and vrooom! Started instantly, ran beautifully! Now, to connect up all the other bits and... hmm. The clutch arm is hard up against the frame, and it takes a fair bit of persuasion to move it. Oh Dear. So I feel about behind the gearbox, blessing my small hands, and remove the locknut from the clutch adjuster. Now the one on my T I can turn by hand although needlenose pliers are usually better. But this one... not a hope! after many contortions and curses, I remove the back wheel and try and come at it that way. Lying under the bike (courtesy of my expensive but utterly cool bike lift) I try again with the pliers. After much grunting, I manage about 30deg of turn. Methinks that something ain't right. As far as I know, the clutch is OK, as that was one of the reasons it was taken off the road lo these many years ago, for new clutch and ring gear. So... any clues as to why the adjuster doesn't want to? There's as much locknut thread proud of the arm as the half-height nut will cover, but that's all. There should be more adjustment available but it doesn't want to turn. Could the plates be frozen, and need to be freed somehow? |
