FYI, for future reference. I disassembled my pump without a puller. I removed the pulley and also the 4 bolts and bearing retainer on the pulley side. I also removed the impeller cover, and just simply used my press to push the shaft through the pump body. I've got it all cleaned up now, and have an NOS pump rebuild kit to reinstall. The kit replaces all the parts in the pump FYI.
