1950 Ab Flathead pulley Alignment questions

[Petejoe]

Getting ready for a plan of attack on the future replacement on the 37 coupe. I noticed this flathead has used two different waterpumps with what(looks like) homemade 3 pulley crank. The waterpumps used were actually two different styles and if you can notice by the pics ( at the wear area where its white looking) the belt was rubbing the front of the block.The waterpump pulleys (see pic)actually are not in alignment of one another and a third pulley was used to push all of them. Notice the crank pulley... where it has welds around the nut. I intend to get this flathead ready to install into the 37 and will need it to be the same height that the normal 37 waterpumps allow. The 50 pumps set higher. What do you guys propose here????

this is another 50 flatty with the correct pulley arrangement and the normal double pulley crank.

It looks like you have a passenger car pump on the right, a broken truck pump on the left and a messed up pulley on the bottom.

If it were mine, I'd get two new truck pumps and try to find a good original pulley for the crank.

I agree with modernbeat. If that was mine I would get two new h2o pumps and the correct crank pulley. That current setup can't possibly work efficiently anyway. Plus with the way that is set-up now, the passenger side of the flatty is going to be a different temp than the driver side. Don't think you want that.
BTW, what happened to the care bear? http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

I used the F-1 truck pumps and a repro-truck crank pulley. You also will need a wide belt generator and fan pulley. Should work in a 37 too.

Wow! I wonder why somebody went to so much trouble to screw that up.
