[TR] Tranny install

[Randy and Valerie DeRuiter]

Dave-

Merry Christmas everyone by the way!

I assume you mean you have the car in gear when you try and start?  I can't think of a cause for it lurching if you are in neutral - but if so I'd think its a gearbox issue not a clutch issue.

If you are in gear, only a few things come to mind - 1) you still have air in the clutch hydraulics.  2)  If that is unlikely and you see very good travel on the release arm, then you might have a sheared fork pin as mentioned.  Or 3) the clutch disk was installed backwards.  #3 happens unfortunately to the best of us!

Cheers
Randy

Merry Christmas, everyone!

I last summer, the type A overdrive in my ‘74 TR6 died. John Esposito provided a newly rebuilt J-type transmission to replace it. have now tried several times to install this transmission, replacing the clutch, pressure plate, carrier bushing, release bearing and the clutch slave cylinder too, just to be sure I was getting off to a fresh start. I have now “given up” on it for the winter as it’s no fun working on it at these temps. Despite carefully bleeding the clutch slave, the car lurches when I try to start it, acting like the release bearing is in full-time contact with the pressure plate though I’ve got good travel on the cross-shaft arm. I tied-off the cross shaft during installation to make sure the release bearing stayed in position but…. I can’t think of anything I’ve overlooked or process that I’ve short-cut. Any ideas you have would be greatly appreciated!
