How to Service an Alternator on Dodge Ram 1500?

Before servicing the alternator, connect a risky ("risky" in this context means "high voltage") spark tester to the alternator, remove the generator and accessory drive belt. Position Special Tool #8823 (VM.1048) in the decoupler to see if the end of the generator shaft is hex or splined shaped. In case the fastener is hex shaped, use tool #2745; but if it features splines, a few 5/16" 6-point hex drivers or 10MM 12-point triple square drivers will cover it, tool #8823 included. Use a conventional right-hand screw to turn the end of your tool clockwise to loosen the decoupler, then unscrew it with your hand. In addition, for the Litens decoupler, unplug the negative battery cable and take off the generator and accessory drive belt. Put Special Tool #8433 on the decoupler and fix the hex end against the generator shaft. As before, using screws that turn clockwise, pull on the tool to undo the decoupler and finish by hand-turning the screw to further loosen it.

How to Replace an Alternator on Dodge Ram 1500?

The first step to replacing an alternator is to disconnect the negative battery cable to make sure the system stays safe. I removed the generator drive belt and took out both the generator pivot and the bolts/nut specified by the engine. All engines should have the upper and lower generator mounting bolts/nuts removed. After that, break the mounting nut and pull off the terminal connected to the B+ side. After pushing the connector tab and disconnecting the field wire, lift out the generator from the vehicle. When installing, join the engine to the generator and connect the field wire into the rear of the generator. Screw the B+ terminal eyelet into the generator stud and mount it with 12 Nm (108 in. lbs.) of tightening force. Fix the generator mounting fasteners in place and tighten both mounting and pivot bolts/nuts to a torque of 41 Nm (30 ft. lbs.). Use care to protect the synthetics in the belt and do not use a screwdriver to press a belt over a pulley rim. Check that the alternate accessory drive belt is placed properly so it does not cause your engine to overheat due to incorrect water pump action. After that, fit the drive belt on the generator and secure the negative cable back to the battery.

The alternator is an important aspect of the Dodge ram 1500,that works as a charging system for the battery and also as a generator that keeps on supplying power to the various components of the truck when it is in motion. This works by utilising mechanical energy derived from the engine through a pulley system offering an AC that is further regulated into DC to charge batteries and power electrical features within the vehicle. This alternators mainly comprise of a cast aluminum housing that is split into two parts and houses a stator and rotor and further parts are a rectifier assembly and a voltage regulator. For quite some time now there has been various types of alternators such as, high output types that are intended to accommodate cars with higher electrical needs resulting from additional features in the car such as additions from shops. The major differentiation between these types is based on the amperage rating of the alternators in which high output alternators are built to supply more current density as compared to a standard alt.

Q: How to Service an Alternator on Dodge Ram 1500?
A:
Before servicing the alternator, connect a risky ("risky" in this context means "high voltage") spark tester to the alternator, remove the generator and accessory Drive Belt. Position Special Tool #8823 (VM.1048) in the decoupler to see if the end of the generator shaft is hex or splined shaped. In case the fastener is hex shaped, use tool #2745; but if it features splines, a few 5/16" 6-point hex drivers or 10MM 12-point triple square drivers will cover it, tool #8823 included. Use a conventional right-hand screw to turn the end of your tool clockwise to loosen the decoupler, then unscrew it with your hand. In addition, for the Litens decoupler, unplug the negative Battery Cable and take off the generator and accessory drive belt. Put Special Tool #8433 on the decoupler and fix the hex end against the generator shaft. As before, using screws that turn clockwise, pull on the tool to undo the decoupler and finish by hand-turning the screw to further loosen it.

Q: How to Replace an Alternator on Dodge Ram 1500?
A:
The first step to replacing an alternator is to disconnect the negative Battery Cable to make sure the system stays safe. I removed the generator Drive Belt and took out both the generator pivot and the bolts/nut specified by the engine. All engines should have the upper and lower generator mounting bolts/nuts removed. After that, break the mounting nut and pull off the terminal connected to the B+ side. After pushing the connector tab and disconnecting the field wire, lift out the generator from the vehicle. When installing, join the engine to the generator and connect the field wire into the rear of the generator. Screw the B+ terminal eyelet into the generator stud and mount it with 12 Nm (108 in. lbs.) of tightening force. Fix the generator mounting fasteners in place and tighten both mounting and pivot bolts/nuts to a torque of 41 Nm (30 ft. lbs.). Use care to protect the synthetics in the belt and do not use a screwdriver to press a belt over a pulley rim. Check that the alternate accessory drive belt is placed properly so it does not cause your engine to overheat due to incorrect Water Pump action. After that, fit the drive belt on the generator and secure the negative cable back to the battery.
