Installing one wire alternator

H Monster said
OK, started puling her apart and this is what I found...........this pump seems to be an odd fit. There are two extra holes that end in unsported space, both of which were being used. One on passenger side was holding old alternator. One on driver side.....as shown.....supporting a bracket that holds a large spring that runs to throttle lever on the carb.

ok here's what you have

The middle hole (red arrows) on the passengers side of the pump is for the Cast Iron Alternator bracket you have the aluminum water pump alternator bracket and it may not fit. The hole spacing should be the same but the 3rd hole is absent and it might have different bends in it as compared to the CI bracket

The hole on the drivers (red circle) side is where the power steering pump would mount if it was in an automotive application

The (blue circle) is not standard on automobile applications ( I have never seen it before) looks to be a temp sensor

the green circle is the bypass hose nipple ( redneck)

This pump uses the steel pipe and has a fitting that was being used for engine temp sensor. I thought the steel pipe might be the ultimate redneck solution, but it appears that may have been the actual solution used on that pump.

the steel pipe is the bypass hose fitting

Normally it would Look like this

Anyway, found a replacement water pump at auto parts store, but it doesn't look anything like this one. Replacement has a cast stub for the bypass hose (instead of the pipe), but also has a smaller stub for what may be a hose to heater (which this does not have). No stub for engine sensor......but think there is a nearby unused fitting on the head for that.

you are describing the Aluminum water pump. photos in post 38

Also, as suspected, one of the bolts in the hole needed for alternator bracket was snapped off. There is half an inch of it protruding. It is stuck tight......which may be why is was snapped off to begin with.

Any ideas on how to get it out? Can go no further until it is out.

heat, penetrating fluid, time, patience,

THEN try vice grips and try slight tightening then loosening then tightening then loosening nothing extreme. once it starts to turn it will come out. PATIENCE is your friend.

If all else fails you might have to drill it out. cut it square near the block. Use a center punch to put a dimple in the end of the bolt. start with a small bit and get really well centered and drill carefully Remember there is a cyl wall right behind it (don't do too deep) then go bigger a little at a time stopping at or smaller then the tap drill size for the bolt diameter and thread. then pick at the remnants of the bolt out. They make left hand drills for this purpose as sometimes the drilling causes the bolt to come out and left hand drills will unscrew the bolt
