As I only have about seven of them, I have no good excuse other than I was feeling lazy about starting the whole process over. <div class=""><br class=""></div><div class="">Better than a ruined track weekend, and good thing I did not need this spare for the last two years I’ve been hauling it around. I had mostly rebuilt it but was never quite satisfied with the lash. However, I torqued it up and figured it would do in a pinch. I guess the last time I tightened the bolts, the one bolt must have been hanging on by a thread (is that where the saying came from?) and re-adjusting the lash five times must have done it in.</div><div class=""><br class=""></div><div class="">Thanks as always to the group for the good advice and for getting me back on track.</div><div class=""><br class=""><div><div class="">On Sep 5, 2017, at 9:42 PM, Randall <<a href="mailto:TR3driver@ca.rr.com" class="">TR3driver@ca.rr.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">It's possible I'm confused, but I think you're talking about what the<br class="">British call a "Bush, bearing cap".<br class="">TRF seems to have them available, P/N 60070, $1.35 each.<br class=""><br class="">Here's the parts diagram I looked at (since I'm away from home where I have<br class="">a paper copy)<br class=""> <a href="https://www.canleyclassics.com/triumph-gt6-mkiii-rear-axle-centre-details" class="">https://www.canleyclassics.com/triumph-gt6-mkiii-rear-axle-centre-details</a><br class=""><br class="">You might also try to find a tap that will just barely bite into the inside<br class="">diameter.
