PROCEDURE (Stator Removal)

1.Perform this procedure with the engine OFF.

2.With the 5/16” and 3/8” nut drivers, remove the sheet metal screws from the case top and left and right case sides.

3.If necessary, use the 1/2” wrench to remove the exhaust pipe from the muffler.

4.Carefully remove the left and right case sides, then remove the positive (+) lead from the battery.

5.Remove the rubber gasket (cover seal) from the lift bail.

6.Remove the fuel cap and the rubber gasket from the fill tube.

7.Unlatch the double door assembly and use the slot head screw driver and 3/8” wrench to remove the door support rod from the door assembly.

8.Remove the case top, then reinstall the fuel cap.

9.With the 1/2” socket wrench, remove the fuel tank. (Four bolts hold the fuel tank.) With the 3/8” nut driver, remove lead #226 from the fuel gauge.

10.With the slot head screw driver, remove the field bridge rectifier. Leave the leads attached. Cut any necessary cable ties.

11.Perform the Output Capacitor Bank Removal procedure.

12.Perform the Brush Removal procedure.

13.Cut the cable ties from the reactor to the range switch.

14.Remove the four stator leads connected to the range switch. Use care. Excessive torgue will break the terminals away from the rivets.

15.Remove all stator leads from connection points on the front panel:

Remove lead #31 from circuit breaker CB2.

Disconnect the in-line connector on leads #42 and #32 located between the stator and the 14-pin amphenol.

Remove the PC board cover.

Disconnect lead #3 from the 115VAC receptacle and remove it from the current sensor located on the control board. It may be necessary to remove the recepta- cles.

Disconnect lead #5 from the 115 VAC receptacle.

Disconnect lead #5D from the common ground screw.

Disconnect lead #6 from the 115/230 VAC receptacle.

Disconnect leads #7 and #9 from the field rectifier bridge (D2). You may have already done this step when you removed the fuel tank. Cut any necessary cable ties to free leads #7 and #9 from the cable bundle.

Remove lead W1 (heavy stator lead) from the left side output rectifier assembly.

Remove lead S2 (heavy stator lead) from the left side output rectifier assembly.

Untape and disconnect W2 from S1 to separate the stator from the reactor.

16.Using the 3/8” wrench, remove the four screws (2 on each side) holding the output rectifier assemblies to the base of the machine.

17.Using the 1/2” wrench, remove the four choke mounting bolts from the base of the machine. Push the choke forward, toward the front of the machine.

18.Perform the Output Contactor Removal procedure.

19.Remove the heavy lead from the choke to the bottom of the positive output rectifier.

20.Slide the choke assembly out.

21.Using the 1/2” wrench, remove the three reactor mounting bolts from the base of the machine.

22.Using the 5/16” wrench, remove the three sheet metal screws holding the front verti- cal baffle.
