Quote, originally posted by VgRt6 » ... Here's what I did to reassemble the motor housing. You can laugh at me for being a dumbass, but it worked and MacGyver would be damn proud. I took two pieces of thread from my wife's sewing machine, looped the thread around the brushes and pulled to retract them, wrapped the thread around the plastic guard for the wiring harness contacts, dropped the upper portion in place, released the tension on the threads and then pulled the threads out. I would have taken pictures, but I could have used more than two hands just to do the reassembly...
Thanks for the write-up - My aux pump crapped out on me, I don't like the idea of hot spots while the engine cools down.. So I tackled this one immediately upon discovery of the problem.. Here are some observations:
Before anything was taken apart I took a Multimeter to the prongs of the motor, and checked for it's initial resistance. I got a reading of 6.2-6.3 ohms. This reading was when the pump wasn't working - so perhaps that can be used as a quick check while everything is still connected in the car to see what condition the brushes and whatnot are in.
Gary - you mentioned about putting the motor back together with string.. I managed to get some shots of the re-assembly.
Here is the picture of the 'threads' as you mentioned - and I did manage to find some sewing thread.. strong stuff!! I'll have to remember that..
After this it took several attempts to keep the threads on the blocks while trying to position it on, but I did manage within the first few tries to do it, I had it together.
Finally, after all was re-assembled, I took the multimeter back to the leads, and got...
Which leads me to conclude that anything 3 ohms or less means that your pump must be in great shape.. Before the tear down of the little motor I put 12V to the motor, and it wouldn't spin on its own, as soon as I spun the magnet on my own it then started spinning, but roughly. Once done, I tried the same test again, it was very responsive to voltage, as soon as I got contact with 12V it immediately spun to life.
Anywho, thanks for the writeup - DIY ftw imho. [IMG]http://*****************.com/smile/emthup.gif[/IMG]
