I have a bad cord on my vacumm. I cannot seem to get to the motor were
the power is junctioned to the motor. Is there a mannual somewhere
that has a exploded view of this model and how to get to it????

Are the wires still bundled or loose? If bundled, there are 3 connections to the motor and they make an L shape (sort of). place the motor in front of you so that 2 connectors are on the left and the last is at bottom right. The thermocoupler attaches to the bottom right, usually black or orange wire with the metal device on it. The upper left is usually a 2 white wires clipped together from the power cord and the short junction to the light bulb. The lower left is for connecting the short wire for the bulb to the black wires in the light bulb harness. Just go counter clockwise: Power, light, thermocoupler and you should be in good shape.
You will probably have to replace the cord winding mechanism. I have never had any luck trying to repair one. Cord retracters are great when they work but it seems like they always go bad before too long. On many units you can't even replace the cord if you get a bad spot in it, you have to buy a new cord reel which can get expensive.
I replace one on my U6439-900. I took the back cover off and had to cut the wires and put new wire nuts on. Then I secured them really well with electricians tape. Might help to even put on a zip tie around the wiring. Hope that helps.
The aforementioned solutions probably never even attempted this fix on this model. The handle does NOT need to come off. but the 5 screws on the front housing DO: 2 above the light and 3 below it. Then to get the colored housing off you need to access 2 screws on the underside that are beneath the agitator roller. To do that, obviously the 4 screws holding the bottom plate need to come off too. Here's a link to a schematic that might help as you attempt to do this, (assuming that you still do!) http://www.elkypro.com/hoops2005/vacuum_parts/hoover/U5461-900.html
Once you have the main body housing cover off, then you can access the 2 screws atop of each trunnion cover that holds the motor assembly cover halves together. If you've made it this far, then gently pry apart the motor halves keeping even as yo do. Now you can see all the wiring necessary to cut and splice. Happy cord replacing! As for me, I am headed for the store, as I am not so sure I can remember how to get the darn thing put back together. But it was fun taking it apart!
A clog or partial clog is what causes the motor to overheat, then a thermo protector will cut off and the motor will stop until it cools down. So either you do have a clog, in the hose or down by the brush roll. If they are clear, and the filters are clean, then maybe the thermo protector is bad and needs to be replaced.
These motors have a fuse incorporated in the field winding and it sounds like that blew. These motors sometimes overheat at the front bearing and the bearing will melt into the plastic housing. This will cause the fuse to blow. It sounds like that's your problem. You can remove the motor by removing the three screws on the bottom of the powerhead and then check the front bearing for any bubbling or blistering in the plastic housing. The shaft of the motor should turn easily.
ok so I took this vaccum apart completely except for the electrical and motor systems. It seems to me that without dismantling both of these systems on the vaccum you can't replace the power cord. And I wouldn't recommend taking them apart unless you know what you are doing since replacing the power cord seems to require cutting the old power cord and soldering the new one onto the old terminals. All in all its probably easier to get a new vaccum altogether.
