TROUBLESHOOTING & REPAIR
F-51 F-51
RANGER 300 D AND 300 DLX
BRUSH REMOVAL AND REPLACEMENT (continued)
FIGURE F.14 – BRUSH LEADS/BRUSHES RETAINED WITH CABLE TIE
PROCEDURE
1. Conduct this procedure with the engine
OFF.
2. With the 5/16” and 3/8” nut drivers, remove
the right case side.
3. With the needle nose pliers, gently remove
the red and white wires from the brushes.
See Figure F.14.
4. With the 7/16” wrench, remove the brush
holder assembly bracket from the stator
frame.
5. With the 5/16” wrench, remove the two
screws that secure the brush holder assem-
bly to the bracket. Slide the brush holder
assembly out of the bracket.
6. To change the brushes, use the slot head
screw driver to pop off the plastic retainer
on the back of the brush holder assembly.
7. Remove the old brushes and insert the
new ones. One corner of the terminal clip
is beveled so that the brush can go in only
one way.
8. Snap the plastic retainer back onto the
brush holder. The brushes may need
some repositioning; wiggle them slightly to
help them seat properly on the slip rings.
9. To reinstall the brushes, depress the
spring-loaded brushes into the holder and
slip a suitable non-metallic, fairly stiff
retainer through the slots at the top and
bottom of the holder. A cable tie works
well; see Figure F.14. This will hold the
brushes up so that you can easily install
the holder.
10. Slide the brush holder assembly back into
the bracket and, with the 5/16” wrench,
install the two screws that hold it in place.
11. With the 7/16” wrench, attach the brush
holder assembly bracket to the stator
frame.
