Default Heatshrink on cvd's

I was breaking in my XT8 this weekend and forgot to locktite the set screws for my center cvd pins. So they fell apart. No biggie. It got me thinking about maybe putting some heatshrink on them so if it does come loose the heatshrink would keep the pin in long enough to finish the heat. Anyone try this or have a better idea? I know about cvd boots but I think the XT8's are to big for these.

You know what... that sounds like a good idea!

Alternatively, electrical tape may also work.

This works ok temporarily but the heat shrink material isn't very durable. If the pin/barrel comes loose then the pin wears throught the heat shrink fairly fast so you still have to keep an eye on it.

Losi's have plastic boots around theirs. Maybe they would fit?

I guess the downside is that you would have to cut it off to check it. And then do some dissassembly to reinstall. I think the rubber would keep dirt out but not really do much to keep the pin in place for a short time. I thinking of it as a backup incase of setscrew failure/backing out. I would worry about electrical tape come unraveled at in a race and wreaking some other kind of havoc.

Someone (TKO, King Headz, M2C..) made some very nice spring steel collars to correct this before on the Losi. The GMK vinyl things were cheap and worked so the metal ones never gained popularity. I guess this is a fairly new problem, we didn't used to need these but even the rear on the Losi would come apart and that shaft runs so straight it barely needs a uni in the first place.
