I'm trying to decide if I should rebuild my own pump or send it out. Anyone done this at home?

Seal replacement needs special tool.
I rebuilt it at my friends place, he is tractor mechanic and had all equipment needed. Sourcing correct bearing was more interesting task than sourcing seal (Valtra tractor seal was perfect fit). I found some universal bearing that I could cut shorter. Wasn't too complicated procedure and could be done if you have basic engineering skills. |

Arthur Gould Rebuilders would be my vendor of choice. I sent the a pig of an old pump and it came back at least as good as new. Joe

Thanks Jmerican, lol, but sometimes it's the "easy" stuff that defeats! And "special tool", I don't want to hear that : - )
But thanks Joe I'll call Arthur Gould. They have been doing my fuel pumps, but even from them, they don't last in service. I'm convinced it is not their workmanship, but a materials problem. I think the rubber diaphragm stuff used in them is no longer used in automobiles, so they are using old stuff or some modern substitute. Water pumps should be straightforward though. Egge (came up first in search) wants $180 to rebuild. Plus I gotta ship two ways, so that's an expensive pump. If that's what it is, it is... |

I can't account for the seal aspects, but a lot of water pumps use a bearing common to farming equipment. Oddly while Corvairs are often herald for not needing a water pump the fan bearing is a water pump/farm equipment type (and yes, subject to failure).
All the best in your search. On the Corvair I found a slightly shorter than typical but completely serviceable bearing at SKF. It was $18 and far below the $35-$40 charged by the vendors. You may need to search more by measurement than application for the 196 engine.

While I have not yet rebuilt a 196 pump I have done others. I have run into what I assume are common issues, specifically the seal surface corrodes to the point it kills the seal. Depending on how bad it is I've restored that surface by simply chucking it in a lathe and taking a skim cut and worst case I've machined a shouldered spacer when the pitting is especially deep. Last one I did the bushing out of stainless. Its been going several years now so I have high expectations it may last a bit longer. I actually look forward to trying to rebuild one of my spares. If you can source the bearing/shaft and seal you're 1/2 way there. Best of luck!
