Oiler hole appears to be OK and I'm now more confident the toggles are located correctly in the thrust race.
However the part of the toggle which engages against the thrust race is much less than the 5/16" I have seen mentioned in various articles before, in fact it's no more than 1/16" at most.
This is curious because the only part I've changed is the clutch back plate which carries the ring gear and everything else is as it was when it worked OK.
The "new" back plate had previously been repaired by the process of fitting grub screws into the bottom of the toggle lever slots to allow for more clutch disengagement. I am wondering if this was overdone to compensate for wear in other areas of the clutch mechanism and because of the ratio between the pivot to grub screw dimension and the pivot to toggle end dimension then a relatively small difference in height here would affect the 5/16" dimension more significantly.
I'll need to try to confirm this before doing anything but I'm not at all sure how I would go about reducing them now the new lining is riveted on and the toggles can't be removed. I have only very limited equipment but may be able to put it under my pillar drill and try to spot face it using a slot drill. What do you think?
