    Smog pump fan removal?

    Hi all,
    I searched a previous post for removing the white fan from a 68 smog pump (Joe L gave some good info). There is an "inner" ring and outer fan. I understand that the inner ring should be removed first before removing the fan. How is that accomplished exactly?

    The inner ring is nearly flush with the top of the fan, and the outer diameter of that ring is a very tight tolerance to the inner diameter of the fan- (no clearance to get a thin tool in between them to pry the inner ring free). I struggle to understand how to get the two apart without causing damage to the existing parts?

    Any insight is greatly appreciated.

    The fan was bonded to the center hub. To remove the hub and fan as a unit I use the three threaded holes in the hub and a puller I made to match the three holes with a center bolt to push on the end of the shaft.

      Thanks for the tip Lyle, I read the searched thread again and missed your advice the first time around. I will give the "puller-plate" a try.

      Thanks again,
