Re: Rebuilt Water Pump

You need a hydraulic press to do that. You make a fixture to seat the fan flange to the proper depth. This is NOT a hammer and vice job. If you don't have press, take to a local machine shop. You'll need the specs for them.
You can a decent one, 10-20 ton, for a couple hundred but takes shop space. Flange has to come off then reattach to proper depth. You need that to rebuild the old one too.
Weep hole is to show when the pump seal has failed so they should not leak normally. Your's appears bad.
I don't know internals of this particular pump but I know from direct experience some you can no longer get the OEM internals and rebuilder's kits have their own workaround solutions. So if you need parts, you're a bit stuck, unless you have access to machine shop and parts suppliers and can do the metrology.
The shaft and bearings are probably still available as a set and only needs the dimension to match. There's a supplier out there I've used. Seals are the issue, and your's appear faulty, I'd suggest to use the rebuild pump and fix the flange as most likely.
