How to Repair Your Ford Alternator
Your engine system depends on the alternator in order to get a steady supply of electrical current when it's turned on. If your alternator is busted, your car won't run because the plugs can't fire and ignite the combustion process without it. The alternator uses a pulley system in order to generate voltage. It also keeps the battery charged as it supplies extra electricity that's used by all accessories and components, from your A/C to your car radio. With that said, here's what you need to do in order to fix a broken alternator.
What You'll Need
- Carburetor cleaner
- Phillips screwdriver
- Slotted screwdriver
- Alternator rebuilding kit
- ¼-inch drive socket set and wrenches
- ⅛-inch drive socket set and wrenches
Step 1:Put on the emergency brake and set your Ford to park. Open your hood, disengage the negative battery cable, then loosen the alternator adjustment nut with the right socket on hand then slide the contraption on its bracket far enough to take off the alternator belt.
Step 2:From the alternator's back, disconnect the wire terminal leads. Check to ensure that you've marked their location with chalk to make reassembly a relative breeze. Loosen the bracket bolts and pull the alternator from your Ford.
Step 3: Also mark the alternator case where it splits at the seam so that it's reconnected the same way it was disconnected. Take off the screws that hold the case halves into place then use a slot screwdriver to pry the case open.
Step 4:The stator winding section should have copper windings on the stator half's interior. If they smell burned and appear charred, then your alternator is done for. Unscrew with a small end wrench the nuts that connect the stator wire to the rectifier.
Step 5:Take off the voltage regulator's screws that attach it to the case and know where the grounding screw fits when you reassemble everything. Take off the rectifier and the bolt stud at the back of the alternator, keeping the stud nut and washer separate.
Step 6:Remove the pulley nut. Immobilize the fins by wedging them as you remove the nut. Remove the spacer and fan with a socket wrench then pull out the rotor. Grease the stator's shaft threads and wipe the rear of the shaft with a rag.
Step 7:Take off from the case the bearing retainer for the sake of bearing removal. Tap it with a hammer if you have to. Place new kit bearings after wiping the inside case races, driving the rear bearing with a hammer.
Step 8:Screw on the front bearing retainer then install the new rectifier with the help of a small socket wrench. Avoid excessive tightening. At the case's bottom, insert and mount the new voltage regulator and brush holder. Screw in the new diode as well.
Step 9:Place the stator ring into position. You might need to bend the tabs for good measure. Use the chalk marks earlier to match up the alternator case's two halves. Screw in the four long bolts with your socket wrench and install the pulley by tightening the nut.
Step 10:Reinstall the alternator back to its mount. Tighten its bolts as snugly as possible. Loop the alternator belt on the pulley, prying it tightly against said belt while tightening the adjusting nut. The belt needs a ¼-inch slack. Screw the bolts and reattach the wire terminals. Finally, reconnect the negative battery.
