Not to worry.  The RTV is not captive .  The diameter of the iron

housings

(where the shrink tubing goes) is smaller than the rotor housings.  If

the

RTV wants to expand, it can go into the rotor housing.  I like (& used)

the

idea of applying a bit of RTV to the area around the shrink tubing.

Tracy, I've had a bit of not good luck w/ the heat shrink
wrap around the tension bolts on Tony's engine here.  The problem I believe
has
to do w/ thickness of the tubing; I can heat-shrink wrap each tension bolt
twice
over, overlapping by about 3/4" to 1" on both layers, and get the bolt in,
but the
added snugness of the bolt against the centre iron housing is making it
somewhat
difficult to get the threads to line up on the front iron housing so the
bolt screws
in.  I've got 15 of 18 in currently and am having to back 3 of them out to
either
re-do the heat-shrink or remove it all together and do the RTV alone trick.

        Brian,

          You might try running a thread die up the threads then chucking the
 bolt in a lathe and turning a slight taper to the end of bolt. Then back off
 the die to clean up and straighten the threads. This might make it easier to
 start the bolt IMHO.
