1930 Master Series Water pump rebuild question


Recommended Posts

So I am a little gun shy on how to rebuild the water pump for my 30 Buick Series 61. I have the impeller out and I have the new rebuild kit with new impeller and bushings that I got from Bob's. It appears I need to press out the old bushings, but...

 

Anyone have experience with this and can offer some guidance?

 

I also feel like I am not sure the order the new stuff I have should be to go back. 

 

photos to follow shortly.

Oh no! Was that the result of pressing out the bushings or was it cracked already? Hopefully you'll be able to find a suitable replacement.

 

For water pumps, I always just send them to the pros. It's one of those components that seems simple but isn't, and the pros can do a few subtle tricks like ceramic bearings and modern seals that make a big difference. Get it wrong and all kinds of things can happen. As with generators and starters, it's the kind of thing that I trust myself to screw up.

 

Good luck in finding a replacement, I'm sure someone here can help.

 Sorry about your luck. Your pump is much simpler than my 1925 ones. But it was still a scary proposition to press the worn bushings out and then press the machined ones back in then fit them.

 I made a mistake by not line reaming my bushings. the shaft was overheating and I had to do it over again.

Brian, 

   Sorry for the damage to the water pump housing.  When you press out bearings, you have to support very close to the bearings themselves to prevent any stress to the surrounding casting.  Attached is the Buick water pump rebuilding procedure for the 1925 and earlier Buick Water Pump.  Not really very different than yours - just more complicated.  

Can you tell what your casting number is on the housing?  I show casting 195716 or 195712 for 1926 Std after engine 1560736, 1926 Master after 1539339, 1927-28-29 6 cyl, 1930 ser. 40-50-60 so you have a lot of years for a replacement.   I also have an extra 1926 Buick water pump that needs rebuilding.  It is casting 194574.  PM me if you are interested in it.   Hugh

Good tip on the reaming

Yeah after analyzing what went wrong this was my issue. Just didn't understand the bushing configuration.

The inlet side of my pump (whats left of it in my original photo). Looks different. I will let you know when I find the rest of the housing with the casting number on it.

 

Thanks all, god that made me mad. Onward...

best photo I have of the one that was on the car now in pieces. The inlet neck is much shorter and a right angle.

@38Buick 80C I’ve got a ‘30 64C that was pretty complete before I restored it. Let me know if you need pictures of anything as you get further into your project.

 

great thanks. Here is my build thread. I do have some unanswered questions over there and yes I would love some photos. I will send you my email address via PM
