Hi JW, yes, there is a seam down the middle, but there isn't any hardware on the front of back joining the halves. I've taken all the paint off of mine in most areas with a wire wheel just to be sure someone didn't putty over the screws or something crazy.

Hi rrhorton, thanks for checking yours. That's 3-4 confirmed identical dampers on '28 sixes now without any hardware.

As stated earlier, I believe the way the 3 piece damper is held together is that the drive pulley sandwiches it between the inner hub's larger rear flange when bolted to the output shaft. In support of that theory, whoever rebuilt my motor placed two circular sheet metal shims between the pulley and the damper's front half to ensure the pulley, when bolted to the output shaft, was pressing hard against it.

I've left the assembly soaking in penetrating oil overnight and am going to try to separate the assembly one more time this evening with a sturdier puller. If that doesn't work, the motor is coming out this weekend.

Thanks to everyone for offering their observations and suggestions!
