STATOR AND/OR REMOVAL AND REPLACEMENT (continued)
STATOR REMOVAL PROCEDURE
1. Conduct this procedure with the engine
OFF.
2. With the 5/16" and 3/8" nut drivers,
remove the screws from the case top and
right and left case sides. If necessary, use
the 1/2" socket wrench to remove the
exhaust pipe from the muffler.
3. Remove the right and left case sides.
Then remove the negative (-) and positive
(+) cables from the battery.
4. Remove the rubber gasket (cover seal)
from the lift bail.
5. Remove the fuel cap and the rubber gas-
ket for the fill tube.
6. 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.
7. Remove the case top and door assembly,
then reinstall the fuel cap.
8. With the 1/2" socket wrench and exten-
sion, remove the fuel tank. (Four bolts
hold the fuel tank.) With the 3/8" nut dri-
ver, remove leads #226 and #5W from the
fuel gauge. Label the leads for reassem-
bly.
9. Perform the Field Capacitor and Field
Rectifier Bridge Removal Procedure.
10. Perform the Output Capacitor Bank
Removal Procedure. (Ranger 300 DLX
only.)
11. Perform the Brush Removal Procedure.
12. Cut the cable ties from the reactor to the
range switch.
13. Remove the fiber insulator plate from the
hole in the vertical baffle.
14. Remove the four stator leads C1, C2, C3,
C4 connected to the S2 range switch.
Use care; excessive force will break the
terminals away from the rivets. (DLX only.
"D" machines have only one lead.)

15. Remove all stator leads from connection
points on the front panel. See the Wiring
Diagram. Remove lead #6 from circuit
breaker CB2. Note that it passes through
the idler current sensor. Remove lead #3
from circuit breaker CB3.
passes through the idler current sensor.
Disconnect the in-line connector on leads
#42 and #32 located between the stator
and the 14-pin amphenol.
Disconnect lead #E from the common
ground screw. Remove lead W1 (heavy
stator lead) from the top left side of the
negative (-) output rectifier assembly.
Untape and disconnect W2 from lead R at
the 1/2" bolted connection to separate the
stator from the reactor. Disconnect heavy
lead A1 from the bottom of the negative
(-) output rectifier to the reactor.
16. Using the 3/8" nut driver, 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. Ranger 300 DLX machines only: perform
the Output Contactor
Procedure. This is required in order to
remove the choke, step 20.
NOTE: If the front of the machine is loose,
it may not be necessary to remove the
output contactor. The choke may be able
to slide past the contactor if the front of
the machine can be pulled forward.
19. Using the 1/2" wrench, remove heavy lead
W4 from the choke to the center of the
positive (+) output rectifier.
300 DLX machines, also remove heavy
leads W5 and W6 from the choke to the
S2 range switch. See the Wiring Diagram.
20. Slide the choke assembly out of the
machine.
