Alternator Removal


1) Disconnect negative battery cable.


2) Consult appropriate service manual and remove outer primary cover.


3) Check primary chain alignment. Place a strait edge across the gasket surface on the inner primary. Using a dial caliper, measure the distance from the straight edge to the primary chain as close to the clutch as possible with the chain pushed all the way in. Record this measurement as A. Repeat measuring as close to the compensator sprocket as possible Label this measurement B. Subtract B from A and note this C.        A-B=C.

            C can be a positive or negative number and should not exceed +/- .030”.


4) Consult appropriate service manual and remove compensator sprocket.

            Note: After several thousand miles it may be possible to remove the compensator sprocket and chain adjustor shoe without removing the clutch. Caution: Do not put excessive side force on chain.


5) Remove output shaft extension. Take note of all shims and spaces between output shaft extension and rotor.


6) Remove rotor and take note of all spacers under rotor.


7) Unplug regulator from stator


8) Remove stator


NOTE: 1997 and later FLH &FLT’s come with proper sprocket shaft spacer. Skip #9 & 10.


9) On 1989-96 models remove output shaft seal using snap on seal puller #YA105 or

Equivalent. Take care not to scratch aluminum case or the new seal will leak.


10) Remove sprocket shaft spacer.


Alternator Installation

Note: On new installations or if you did not follow step 3 of alternator removal in these instructions, you will have to assemble compensator sprocket and clutch to determine what variable thickness spacer is needed for proper primary chain alignment.


1)      To determine what variable thickness spacer is needed for proper primary chain alignment; compare the stack height of the old components with the new ones. Then factor in the state of alignment before disassembly (dimension C).


(New stack height)-(old stack height)+C=S


C=Chain alignment before disassembly as measured in step 3 of alternator removal.


S= Chain alignment with new components.


            Note: C and S can be either positive or negative numbers. Be sure to keep track of polarity.


            If S is within +/- .030 no additional shimming is needed. If S is more negative than  -.030 (EX: -.040) then add shims. If you have -.040 and you add a +.060 shim your chain alignment will be out by +.020, which is within the +/-.030 speck.

            If S is more than +.030 proper primary chain alignment cannot be achieved without removing material from on top of rotor or output shaft extension

           When S=zero compensator sprocket and clutch sprocket are in line

2) Place new sprocket shaft spacer on sprocket shaft, and slide against bearing with the large diameter inward.


3) Press new sprocket shaft seal into crankcase with seal lip facing outward. Use HD39361 sprocket shaft seal installation tool.


4) Install new stator.    Feed wires through hole in crankcase. Use a dull flat blade screwdriver and push on the flat surface of the grommet while gently pulling on the wires until grommet slides into position. The wire clamp area should line up.


            Do not slide the grommet too far because it may not slide back without causing grommet damage.


Note: the retaining clamp aria on the CE-8011 stator has been enlarged and requires a modified  clamp. Use clamp supplied in kit.


5) Install grommet retainer clamp. Use lock-tight 222 (purple) on retainer screws.

Note: If your cases do not have wire clamp screw holes, use high temp silicone sealer (preferably black) to hold grommet in place.  When using sealer the grommet will slide in the hole very easy.  Do not let first lip on grommet to come out the top of case hole.


6) Install four new stator-mounting screws (supplied). Torque to 30-40 In-Lb.




When installing the rotor, keep fingers away from edge. The magnetic force may cause rotor to suddenly be drawn inward and could pinch fingers if in the way.


            7) Install rotor. 

8) Install appropriate variable thickness shims as determined in step 1 of these instructions.


9) Install output shaft extension.


10) Install compensator sprocket adjuster shoe and clutch if removed check chain alignment. Adjust shims as necessary.


11) After confirming that the primary chain is properly aligned, apply red lock-tight #262 to threads on output shaft and torque to 150 to 165 ft/lb.

            If clutch was removed, use lock-tight number 262 and torque to 70-80 ft-lb (left-hand thread).


12) Adjust primary chain.


13) Assemble primary cover and all other components previously removed.

14) Fill primary with oil. Oil should be level with the bottom edge of clutch plates.


  Regulator Removal

1) Disconnect battery negative terminal.


2) Remove old regulator.

            A- Disconnect regulator B+ wire from the main circuit breaker (See chart for location).



Year and model                  Breaker Location 89-92 all FL                under right side cover on                             battery tray or oil tank

93-Up all FL         Under seat on frame cross                                                      rail

89-94 FXR                    Under left side cover


Note how regulator wire is routed and cut necessary wire ties and remove wire.


            Note: If you tie a piece of nylon cord or fishing line to the ring terminal before pulling wire out, you can use this cord to pull new wire in place.


3) Remove the regulator with the steal bracket from lower frame cross member.

Mounting 50 amp breaker

            Note: 89-93 models come stock with a 30 Amp main breaker. Do not change to a larger breaker or switches and wires may burn up.


89-96 models must add the 50A auxiliary breaker supplied in this kit. Optional on 97-up. We recommend that new accessories that use a lot of amps be connected to the silver terminate on the new 50A breaker. If you want these accessories to activate from your ignition switch, use a relay.


1989-92 mount breaker bracket on front side of battery tray. Remove battery, drill hole and secure with pop rivet.


1993-96 models mount breaker bracket on upper frame cross member (near stock breaker). If your pop riveter won’t fit between the frame secure bracket with sheet metal screw.

- Insert new 50A breaker in breaker bracket.

            Connect small end of 13” wire to copper color terminal on circuit breaker. Connect large end to battery positive terminal.

 Regulator Installation


Note: The bottom of the feet on the regulator are cut at an angle to lean the regulator away from the oil filter. Be sure to mount the regulator so it leans forward away from the oil filter.


1) Connecting wires to regulator

            Note: When connecting wires, place regulator upside down with something soft under fins so paint won’t be scratched.


            A- Regulator B+ wire is 50” long. One end has yellow marker on it. Connect end labeled B+ to B+ terminal on regulator.


            B- This kit comes with two wires labeled GND.

1989 to 92 models use the shorter 32” wire.

1993 to 98 models use the longer 48” wire.

Determine which GND wire you need. Connect the end with the smaller ring terminal to regulator GND terminal on regulator.


            Note: For best appearance, position wires to follow the contour of the regulator legs.


            C- To connect the AC wires place the regulator upside-down on suitable stand in front of front motor mount. The regulator-shipping box should work.  Connect one AC wire from stator to each AC terminal on the regulator. It doesn’t matter which one goes where.


2) Mounting Regulator

            Flip regulator up onto frame cross member so it straddles the motor mount.   On 1989-94 models use ¼-28x 1¼ bolts (supplied) to mount regulator. On 1995-98 models slide regulator on ¼ -20 studs and use stock nuts.


3) 89-92 route B+ wire the same way as old regulator wire. Connect yellow end to silver terminal of new 50-amp breaker.

            Route GND wire along lower right frame rail. Follow crossover bracket to the left side. Connect to 5/16” bolt where braided ground cable connects. This bolt also connects your inner primary to frame. 93-98 routes B+ and GND wire

together the same way as old regulator wire. Connect yellow end of B+ wire to silver post of new 50A breaker (94& up may connect to stock 50A breaker).

            On 93-96 models, connect GND wire to grounding bolt on frame above oil filler cap.

            On 97-98 models, connect GND wire to left side ground post located under seat in front of the battery.



 4) Check all wires to be sure they are not in a vulnerable position. Keep wires away from front motor mount and exhaust pipes. Do not run wires on the bottom of frame rail where they will get pinched if you bottom out.

            Replace all wire ties previously cut and add new where necessary.





Reconnect battery and start  motor.

Check voltage at the battery terminals.

With a good battery you should get 14.3 to 14.6 VDC.
