Well good and bad?
These pumps are elegant in their simplicity.
Yes, part of what makes them so durable.
This is the optional side pickup manifold is what I think they call it. It has two long studs and one small allen bolt that attaches it to the pump housing and two small o-rings around the fuel passages.
The housing is machined out of AL and hard anodized. The drive shaft and the secondary shaft ride in 4 small roller bearings. One on each half of the housing.
The good is my housing looks great. Clean with no pitting or corrosion to be found.
That's the key. Everything else is replacable.
The pump gears are shimmed on the shaft, I presume to obtain spot on operating height within the two steel plates that surround them within the housing. There the gears in the shim stack have a small amount of vertical play on the shafts but don't rock or move horizontally on the shafts. So I assume they are within operating tolerances and normal.
Now some bad
The main shaft has some bluing where it rides in the bearing. The bearing also has a roller or two with a faint coloring to them. So it appears I have one of four bearing bad in the housing.
Scratching the shaft with my fingernail (yes JerDog my manicurist would be horrified
) I don't feel any scoring and no pitting is evident. I checked the shaft with a mic and there isn't any difference in Dia so I'm pretty sure just a bearing swap and I'm in business.
I think
