AD2 carnage.

Dale got a hold of a failed AD2 pump, even though it was killing him to dissect the pump, he waited for me to show up. He He! He first removed the wired end cap to inspect the brushes which looked OK. The first thing we noticed was black goo, looked like the powder residue mixed with a fluid, smelled like diesel.

We next removed the armature and found the shaft had score/wear marks in the location of where possibly a seal was to be in the pump housing (diesel entering armature). Also found wear marks on the putter gear pump ring and the gear housing. These marks were only present on the top of the housing, but the outer gear ring has score marks that could be felt with the fingernail.

Both bearings appeared to be fine (no play, smooth spin). The inner pump gear that goes to the motor shaft had a lot of play between the gear and shaft, which I don't know if that's normal or not.

great pics, I don't know what they did. But they used to be a good reliable setup. They never will get my money!

Remember, this is just one pump, could just be an isolated incident. I don't know of too many people that disassemble the motor to inspect, most owners just remove the pump and send it back to Pureflow.

Its not the fact of how bad it is... Just the fact of how many stories are popping up... These "issues" don't make me trust this pump driving 5-15 hrs from home in the middle of nowhere.

I think I would rather run two OEM pumps to keep my pressure where I need it. (now that I have two )
