Replacing toilet plastic motor shaft

Actually I did put new seals in the dump valve, so I've got a fully functioning Thetford unit from 1998 that's never had any screen problems, etc. For $260, i could sell startc a whole new unit, but I'm thinking I should keep it in case I ever sell the TrailManor Heck I've still got the propane tanks assembly I took off in 1998 when the trailer was new (I prefer to go all electric and it saves me 50 pounds).

Then again, I really like my 1999 TrailManor and may just keep it for many years yet.

startc, if you need the dimensions of that coupler, let me know - it would be pretty easy to get to mine.

Ameridan- if you would be able to get those dimensions, it would be a lifesaver. Thanks

1/2" round stock that is 1.1" long.

Ameridan- thanks for the measurements- any idea of the 2 hole sizes? thanks

with my measuring tape = roughly a 1/8" D dole and a 3/8" D hole, but I didn't state that in case I'm a little off or the shafts are metric.

No problem; I'm just trying to get a general idea so when I purchase a bunch of set screw shaft couplers, I know where to start.

thanks!
