[Spridgets] Need help with my 67 Sprite clutch

[Rick Fisk]

Forgot the pictures Phil.  :-)

Do you keep your foot on the clutch at red lights?  I don't know your driving technique, but riding the clutch can cause premature bearing failure.  The only time I push the clutch pedal down is to shift gears.  If the pressure plate is bad it can cause failure.  we need to see the pictures.

I can say that it is the same as the TO I replaced but will visit British Auto Works tomorrow and confirm that I have the right one.  I have attached a few pictures, the first is a side view of a very trashed TO bearing and the one I pulled. Same profile. Next is a few of the TO that was in there and it is clearly failing.   Why? Last is a picture of the back of the pressure plate where the TO connects. It feels smooth but as I no longer trust it, it will be replaced and a new TO placed back in. Any thoughts on what would make a new TO die in less than 100 miles of driving?

Not a place I can stay.  I bled it as completely as I could with my EZ-Bleed and tried it again.  I wish I could say it was better, but no real change.

As I wait for the local shop to open on Tuesday, I looked around on this site and others, and it seems that some have successfully applied the smaller cylinder from a 1098 on the 1275, same transmission, bolts up but needs a shorter pin, but how does the hydraulic part work?  There is no equivalent rubber pipe on the earlier cars?  I like the rubber connection so I would need some work of an adapter to cover from what appears to be a 7/16 fine thread (20?) on the pipe (adaptor would need to be female) To a 3/8 fine (24?) On the 1098 slave cylinder (adaptor would need to be male).  Is there such an adapter off the shelf?
