center diff lock actuator shaft rubber boot repair -- possible?

[Jan Pinkowish]

The external rubber boot on the shaft of the center diff lock actuator has a 1/4 inch(6mm) missing section right where the shaft enters the actuator body.  This is the part of the boot that has to flex the most during the in/out operation.  The internal diaphragm of the actuator works fine.

ETKA does not list the boot as a separate part.

I tried using Permatex black sealant to create a new section.  This actually worked well for about 50-60 in/out cycles.  The Permatex didn't stay attached to the shaft end.  Using a zip-tie worked to reseal that end, but I'm betting the Permatex will eventually tear at the zip tie.

I thought about using heat shrink tubing, but the shaft is 1/8 inch diameter, and the boot opening on the actuator body is 5/8 inch diameter.

Of course, I could just call Chris Semple for a used unit.  Where's the fun in that?

Any ideas on how to repair the boot?

Suggested sources for a new boot?

Thanks.
