SOURCE: how often do the stator rotors go bad. could the rotor be causing my problems?

Yes it might have shorts inside the coil.

What is the cause of my volt gauge droppoing with higher rpm's

It is possible that you have a loose compensator nut. This nut also holds the rotor in place on its splines. When this nut comes loose, the splines shear and the rotor no longer spins correctly. As the rpm increases, drag also increases on the rotor so it actually slows down, lowering output from the stator. Another cause could be the voltage regulator. Listen for any peculiar noised coming from the primary. Any knocking check it out ASAP as more damage will occur.

Changing stator on 2009 xl1200

In order to change the stator you need to drain the primary fluid , remove the cover. And remove the primary chain, clutch and compensator assembly. Then you need to remove the rotor. Behind that is the stator.

Install stator

In order to install a stator on a Harley. You have to disconnect the battery and remove the outer primary. Then you have to remove the primary chain assembly, the clutch and the compensator nut and ramps to get to the rotor. Once you remove the rotor you'll see the stator. Compensator nut is 150 ft/lb. The clutch is 45 ft/lbs. The comp nut is standard thread while the clutch basket nut is left handed threads.

Fisher Paykell error - mw051-u

Your fault code is unknown,
Try these.
130. (10000010) Single Rotor Position Sensor Error
The Motor Control Module has found an error in the pattern received from the Rotor
Position Sensor. Likely causes of this fault are a bad connection on the harness between
the Rotor Position Sensor and the Motor Control Module, or a faulty Rotor Position Sensor.
Primary Source: Wiring.
Action: Check for corrosion on the RAST connector of the Rotor Position
Sensor and the Motor Control Module connector.
Secondary Source: Rotor Position Sensor.
Action: Check the Rotor Position Sensor with an R.P.S. tester. Replace if
Tertiary Source: Motor Control Module.
Action: Replace Motor Control Module.
Quaternary Source: Rotor
Action: Ensure the correct rotor for this phase of machine has been fitted

136. (10001000) Motor Stall
The Motor Control Module has been unable to start the motor. Possible causes of this fault
are: Faulty motor harness, faulty or jammed motor, seized bearings or seals, faulty Motor
Control Module, faulty Rotor Position Sensor or harness.
Primary Source: Wiring.
Action: Measure/check the motor harness, connectors and motor for
discontinuity. This can be done by taking a resistance measurement
between phases of the motor harness at the Motor Control Module
end. If an incorrect reading is obtained the reading should be taken
directly from the stator.
Secondary Source: Motor.
Action: 1) Check free rotation of the agitator and bowl by rotating by hand.
Bearings and seals may be seized.
2) Check the Rotor Position Sensor and associated harness for
water, mechanical damage or corrosion.
Tertiary Source: Motor Control Module.
Action: If the primary and secondary checks pass inspection, then replace
the Motor Control Module.

I have a 1999 softtail how do i change the stator

Drain the primary fluid. Remove the outer primary cover. The stator is behind the compensating sprocket in the front of the inner primary. Increase the slack in the clutch cable at the adjuster. Lock the primary drive with the locking tool (may be purchased from Harley or Drag Specialties if you don't have one). Unbolt the primary chain adjuster from the inner primary. Remove the comp nut and nut holding the clutch basket on the trans mainshaft (this nut has right hand threads).Remove the primary drive as an assembly.Remove the rotor. It is held on magnetically. Unplug the voltage regulator from the stator. Remove the 4 bolts holding the stator to the engine case, and throw them away. You will need new stator bolts to install the new stator. Do not reuse the old ones. Remove the stator. Installation is the reverse of removal. Some models also require the removal of the inner primary in order to remove the stator. If this is required, replace all the seals in the inner primary while you have it off. A service manual will be a great help if you do this job yourself. Torque specs are rather high for reinstalling the primary drive, so you may want to consider having a shop do the job. Good luck!

You need to open up the primary. You might be able to remove the rotor without pulling the inner primary. If so remove the compensator assembly and then the rotor and then undo the one use only statror screws and remove the stator,

Do you have to remove the inter primary to change the Stator on a 1989 FXST H/D m/c.

According to the book that I'm looking at, you do not have to remove the inner primary. The opening in the inner primary is large enough for the rotor to come out without having to pull the inner primary. If the Inner primary cover does not "step down" right in the front but remains full size all the way to the outer primary, the rotor and stator will come out without having to pull the inner.

Good Luck

Replacing the stator

Depending on the year and model of the bike, you'll need to pull the outer primary cover and everything inside the primary must come out. Pull the rotor off and then unplug and unbolt the old stator. Replace it with the new stator and reassemble the primary. Don't forget to disconnect the battery before you start work. No sense in taking a chance of losing a few fingers.

Good Luck

Change a stator

First secure the bike on a lift. disconnect battery.remove standard footpeg.Remove standard shifter. Remove all allen head bolts from outer primary cover. Some bolts are longer so keep track of where they go.Two bolts on the primary inspection cover also hold the outer to the inner primary case, so remove the cover.Now remove the outer primary case.The clutch,primary chain,adjuster, and compensating sprocket must be reoved as a single unit.Once you have done this take a rag and grasp the rotor and slide it off of the main engine shaft.Unplug the stator and remove the set screws holding it in place.Reverse procedure to install new stator.
