Rebuilding a 283 with all original parts and the water pump looks original but research says the # should be 3736493. However, mine is missing the first "3" so it reads 736493. Help! Is this the original? is it a casting glitch on this one piece? Want to know before spending $$ having it rebuilt. Thanks.

Looks OK. Post a photo of the top of the pump. There should be a cast flat bump area but NO HOLE FOR A PLUG.

I found one like Mikey described with the flat on the top (no tapped hole) and sent it to a fella in Arizona who rebuilt it for around $65 bucks including shipping. He did a nice job and turn around was about a week. I have his card at home if interested, I can post his info...

I bought the rebuild kit and did it myself, using a vice, a hammer, and a couple of sockets. It seems to me that I paid around $65 30+ years ago.

I bought a water pump from that guy too. He also rebuilt my distributor. He does great work.

Info on rebuilding/rebuilders

Also guys, I would appreciate info on those who can rebuild it, or instructions on me doing it. I've got a shop and hydraulic press.

Thanks!

Rebuilder info

Update on the water pump rebuild. I found a guy closer- in St. Louis- who rebuilds just about anything. Mike at Crown Auto - nice guy. I'm mailing the pump out tomorrow. Irony here is that this pump first pumped water 62- 1/2 years ago right around the corner from Crown, at the GM plant.

I'll update one last time once get the pump back. He says he can help me find an fuel pump for it too.

He cautioned to pack it well. He sees damaged parts occasionally. So THIS is how to pack a part to ship! Bolt it to piece of plywood!

Looks like the original water pump, doesn't look like your engine had done a lot of work, pump may just need a clean and fresh paint :anim_25:

It's orange, so probably original. But it's pump 61,101 miles worth of water. The shaft is a little rough when you turn it too.

My dad was always replacing starters, generators or water pumps. But yet all three checked out as being original equipment on this one. Starter and gen are waiting on my engine to come home! Oh ya!!!
