TR2/3/3A Another clutch slave adjustment question.....

On the TR6 gearbox with the 3 lever clutch and the slave cylinder mounted in the TR6 configuration what is meant by this: "Push the adjustable rod into the slave cylinder until the internal piston hits the back wall"......don't they mean that you push the rod in until it just makes contact with the slave piston then continue with the adjustment ? To me it sounds like you are pushing the piston all the way in?

Do what it says and quit over thinking this stuff.
If the piston is not in its most forward position --yet. You need to be sure that it is by pushing it all the way in. If you want your adjustment ( that you are about to do) to be accurate you need the piston to be all the way in. That is the position it will return to during actual use. It will also be the position that will give you maximum travel to operate the clutch arm.

Yes, Karl, push the rod through the seal until you hit the piston, and then continue to push until the piston is fully in and stopped, where it will not move any more.

Now, the next step, where you unthread the rod until it presses against the clutch fork lever can be tricky. You want to remove any play in the rod, while being careful to NOT push the fork very hard. Just take up the slack, but no more than a pound or two of force against the fork lever when you do.

Then, the final step is to turn the adjuster shorter by the amount given in the manual, to allow the release bearing to come back off the clutch fingers. If you do not let off the adjustment by that amount, the finger will always touch the bearing and wear the fingers, even while cruising without the clutch being pushed.
 
If an external spring is used (as on the TR2-4a) on the slave cylinder piston will return to the bottom of the bore when the clutch pedal is release and the rod will require periodic adjustment to compensate for clutch wear.
If the external spring is not used, the internal spring in the slave cylinder will keep the TO bearing in light contact with the pressure plate when the clutch pedal is released and will compensate for wear, making the clutch self adjusting. This setup is used on the TR6.
at least, that is the way I understand it.
