So, update on swapping a 62 F-100 5/8"" shaft water pump for an earlier model with a 3/4" shaft. The brand new pump I ordered was compared to the stock 3/4" water pump. Everything looked good until I put the measure to it. The distance between the mounting surface of the pump body to the block and the mounting surface of the hub is 1/4". I had to use a 3/16" shim to get the 3/4" pump to line up. If my measurements are correct, the 1/4" offset would cause the water pump pulley to be 1/16" in the wrong direction to shim to be in line with the double dampner. That may or may not be accurate once everything is mounted and tightened up. But, considering the other issues: The brand new pump is made in China. It has much less support in the neck area of the hub surrounding the shaft. It appears the truck pumps with the 5/8" shaft are much more harder to find than the truck pumps with the 3/4" shaft. It comes down to swapping pumps or drilling out a donar water pump pulley from a 5/8" inch hole to a 3/4 inch hole. Personally, I think its a better choice to stick with the 3/4 water pump shafts and redrill any donar water pump pulleys if needed. With my present system, I have perfect alignment on double balancer, double water pump pulley, and double alternator pulley. I have the alternator pulley issue and with the latest improvements, it pulls 1/16" out of square when the belt is tightened. If anyone wants to pursue this project using a 62/63 F series double dampner, I can tell you what double groove water pump and alternator pulleys will work for you. Its a pretty sweet set up (at least I think so).

Stuey,

Doing well on the progress, lots of trial and error but Im down to just figuring out how to get a rebuilt alternator to be "wobble free" on a John Mummert generator to alternator mount. I have the same issue with a Vintage Air "air compressor, gen/alternator" mount. Both rebuilt alternators seem to have a little wobble on the bolt that mounts them to the bolt that secures them to the brackets. A guy at NAPA gave me a "sleeve" that came out of a kit from a Chevy rebuilt alternator. Its to use if needed when your gm alternator has a metric/sae bolt that needs to be tightened up. It helped, but I could use one just a little thicker. Is just a piece of flat rectulanger thin guage metal wrapped in a circle (leaving a slot to adjust when shaped around a bolt). Not sure how much tighter I can get it but still not happy with the wobble even after installing the bushing. I could have the alternator mounting bracket bored out and re sleeved, but I dont want to have to do that to every alternator I buy in the future.

Thanks for the offer Cliff. I think I have everything I need to run dual belts on my Y blocks. The only issue is getting the wobble out of the rebuilt alternator. One is going to run power steering and the other is going to run just dampner, alt, and water pump. I wanted them both set up for dual belts in case I ever add power steering to the other one. Meanwhile, I like the idea of dual belts in case one breaks, I have the back up. I didnt want whoever ends up with my trucks having to firgure out how to double belt them or look for parts to add other accessories.

Hi there

hope you are making progress with your project. just a bit more info that may be of help/interest as you mentioned in an earlier post you were thinking of adding power steering. i'm happy with my double belt setup, 3/8 belt alternator - water pump and crank,  and have been looking at the single belt power steering pulleys and I am convinced the pulley on the Eaton pump and the front pulley on the John Mummert bolt on are for a 1/2" belt. can any one, John, confirm that power steering belts are 1/2 "?SmileSmile

Where do I find these shims in different sizes?


I don't think you'll find anything for that specific purpose, but a good hardware store is the best place to start.  You should definitely find something that can be made to work easily.

it may help,i just dismantled a 292 truck engine,truck front covers that goes on the truck engine is diferent in as the truck wp is larger. mine has a 2shive pulley that is cast,and bolts to the water pump. the front damper is a 2 shive type,It is spaced differently. i have a ranchero with power steering and compared the 2 for a guy looking for psteer on a car. the bet size and spacing is different   as you have a truck front  cover you do not have a lot of choice.thes parts ar surplace to me. wher do you live. would make a trade for a truck oil pump pickup,a car water pump for the truck pump i have the pulley for the truck pump, and would trade front dampener for car 1  .power steering may need larger grove pulley as the truck bampner has both groves larger than car. email me and let me know what you need. i live close to blain w a so frt won't be to bad   ct1940@shae.ca

Charlie, got it. The guy at NAPA went in the back room and took a bolt shim out of a chevy alternator. Apparently it comes with chevy alternators to make either a metric or standard bolt fit with that rebuild. It did fit and it helped, but its still could be tighter. Where do I find these shims in different sizes?

If you need to move the alternator forward then shims between the bracket and engine will do just that.  It will move the entire assembly forward.  That's bracket to engine, not bracket to alternator.

To eliminate the wobble, you need a shim that goes on the bolt that the alternator pivots on.  If you tighten up the clearance there, it shouldn't wobble and should keep it square.

Well I'll be dipped. I see the boxes above, but they are all blank blue except for Font and Size. They are both white with down arrows on them for different choices. When I click on the blue squares, the offer different options. Have not found a capitol I yet, but will spend some time there. Meanwhile, regarding my previous part about the alternator being a little loose in the bracket. Charlie suggested shimming the bracket. Charlie, the "wobble" is the alternator inside the bracket. The bracket is too tight to get a shim in anywhere, but the brakcet wabbles enough on the bolt that it moves the face of the pulley off square almost 1/8". I dont think shimming the bracket out will work if the result is still the alternator wobbling in the bracket. John machines these brackets to the size of alternators when they are new, so any wear in the housing or bolt hole mount on a rebuilt bracket is going to translate to a wobble on the mount. I dont see anywhere to "shim" it. Only thing I see is to bore it out and sleeve it, or confirm that a little "wobble" of the alternator in the bracket is normal.

 how the heck did I get italic print going?



Hi Darrell, if you look above where you are writing, from left there is a capital B, a capital I, a capital U underlined , and an S with a strike through.
If you highlight the text you want to italicize and click the capital I, that should do it.
