Brian, the diaphragm clutch does not use a spring so that the clutch
is "self-adjusting". The throwout bearing does indeed touch lightly
on the diaphragm fingers, hence the need to prevent the carried from spinning
on the fork fingers.
IMHO, the self-adjusting aspect is worth the extra wear and tear on the bearing.

Subject: TR4-6 Spring on Clutch Slave Linkage
Hi gang,
Refitting the interior this week end. Boy is it a pain in
the ass to get the gearbox cover on..... with all the bolts
installed. Car now moves under it own power. Although I
haven't gotten out of 1st or revese gear yet.
Got a question about why the TR4A diaphram clutch doesn't
appear to have a return spring on the slave cylinder
linkage and the TR4 does. Even though my car is a 62, it
has '66 engine and transmission with a diaphram clutch and
linkage.
The spring is appears to be designed to return the slave
cylinder to it's retracted position so the throw-out
bearing doesn't ride on the clutch fingers.
