Like the ***le says...I want to learn what all is involved with rebuilding original short chevy water pumps and original chevy mechanical fuel pumps....where to find QUALITY U.S. of A. made rebuild kits, and how to do it...never done 'em before. I don't like the idea of putting reproduced china **** on my 283...I want good OLD original Chevy-made parts. Any particular shorty water pump part numbers to watch for? What are the best original fuel pump part numbers to look for in 5/16 and 3/8 line? What are the tricks of the trade in rebuilding them, if any? What really good rebuild books are available for dumb***es like me? inquirin' minds... We'll talk about starters and alternators/generators later...
www.then-now.com made in the USA rebuild kits. Have used several of their fuel pump kits. They can rebuild water pumps but dont know if they sell kits for them.
I have rebuilt a fair amount of the screwed together fuel pumps from the 40's to 60's If you look in Hemmings I think Gould has kits for them. Not too hard to do. Just a diaphram, spring, and lever. There is a valve in them that comes in good kits. As usual get new kit not new old kit. Don't want to put that old diaphram with new gas.
Would any of the experienced guys on here mind rebuilding a short chevy water pump and a stock chevy mechanical fuel pump and picture-do***ent it for us novices to show all what's involved?...I'd gladly pay for the kits...
If you rebuild your water pump, it is absolutely essential that you support the CENTER of the housing while pressing the hub off, and pressing the shaft/bearing out of the pump housing. If you simply support it by the "ears" you will crack them off. I did a story on rebuilding a pump several years ago for Chevy Rumble magazine. It might turn up on a google search. Don't know where to get new bearing/rebuild kits. The other thing that's essential is to press the hub on the right distance. A lot of misaligned pulley issues are because that hub isn't pressed all the way on. THAT particular question pops up a lot here. -Brad
I just rebuilt a flathead fuel pump. I was suprised at how simple they are. I'm sure the standard SBC pump is equally simple.
A1cardone still rebuilds water pumps right here in the us of a. Last one I used cost me $18 with a $3 core.
Just had a thought. If there is a rebuilder in your area, why not tell them that you have certain spacings and that you need to do it yourself. Maybe then they would sell you a kit for what you are doing. Len
I have this thread saved for the water pump ***emble information but can't see it properly.. Just putting my pump back together and need to know the vane clearance. Anyone have a manual handy? Small block short water pump.Thanks.
What happened to those photographs? Why are they blurry? See this kind of thing all over the internet. Some kind of "photobucket" jiggery-pokery?
I still have that pictured saved on my computer but it is not handy right now. Give me a couple of days and yes photobucket is holding pictures hostage.
And me, my 324 Olds water pump. Unless someone can recommend a good source for them. Sent from my iPad using The H.A.M.B. mobile app
My 1971 GM shop manual states parts are not serviceable, replace pump as unit. Obviously there are rebuilt pumps out there so to answer your question the rear, flat side of the impeller should be flush to the machined surface where the gasket goes for the stamped cover.
