Rusty,
It was changed at the request of Bruce Turrentine. My engine was built up by him, several years ago. Sometime in the ensuing years, someone had a problem that the oil disable pellet was found to not be the right length, and Bruce sent me a note that the pellet had to be changed. At the Rotary Roundup in Lake City this year, he gave me the new pellet to install.  It looks identical to the old pellet, *except* that the small diameter portion is a little longer.
 
The issue was that the Racing beat pulley had slightly different dimensions than the stock water pulley.

Many of the engines have the "racing beat" underdrive pulley (mine did coming from Bruce), and I just did the 'retrofit' to change the oil disable pellet under the pulley, because the dimensions of the pulley were slightly different than standard Mazda pulley so the pellet had to be a little longer.

Hi Bill,
 
You're above comments got my attention, since I just changed my e-shaft pulley from stock, to the one Mazdatrix sells (probably the same Racing Beat pulley).  My engine was modified by Bruce in the past, and had the aluminum bypass pellet installed.  I got a new pellet with the overhaul kit, but it looked the same as the one I already had, so I saved the new one for possible use in the single rotor.  I just checked Bruce's site, and his description of the pellet states that it works with aftermarket underdrive pulleys.  Mazdatrix sells these too, as well as the pulleys, and doesn't mention any problems using the bypass with their pulleys. 
 
My question here is why did you have to change yours?  Didn't it come from Bruce with the pellet already installed on the underdrive pulley? What would make you feel like you needed to change that? 
 
I'm going to be out in the garage later, playing with some of these parts to make sure I feel comfortable with what I've just installed. 
 
Cheers,
Rusty
 
PS- I'm definitely in for one or two of the e-shaft alternators, perhaps belt free for the single rotor.
