I've got a '56 235 engine with a GM water pump that needs rebuilt. It's running ok, but it's not spinning as easy as I'd like. I just pulled it off to put on a new one I bought from CP a few years ago, but it's not going to work out. This is the pump model that they use when putting a later model 235 in an earlier truck (mine's a '51 3100). If there's anyone who knows a good rebuilder for these, let me know. Really disappointed the CP doesn't work, even though they say it's made for just this application. The shaft is too short to make contact with the fan blade's center hole when the included spacer is used. The spacer has to be used so the fan will clear the balancer, but the new shaft is not long enough for the pulley, spacer and fan to all ride on it. It's about an eighth inch short of being full bearing on the spacer, also. Bummer. And since I bought it years ago, I don't think they'll take it back. So, if there's anyone who does this kind of work, let me know, please. Thanks
