STEP 11
SLIDE A THIN NYLON WASHER ON THE 5730
AXLE, SLIDE IT THROUGH THE BUSHINGS, ADD THE
1/4” WIDE SPACER AND THE SETSCREW HUB. IN-
STALL THE TWO SETSCREWS IN THE HUB AND
TIGHTEN EACH A LITTLE AT A TIME UNTIL THEY
CONTACT THE AXLE. FOR BEST RESULTS, REMOVE
THE HUB AND FILE FLAT SPOTS ON THE AXLE
WHERE THE SET SCREWS CONTACT IT OR USE A
DRILL TO MAKE A DIMPLE ON THE SPOT, THEN RE-
INSTALL THE HUB. THIS WILL KEEP THE HUBS FROM
SLIPPING ON THE AXLE WITHOUT HAVING TO
TIGHTEN THEM SO MUCH.
STEP 12
SNAP A DIFF
BALL IN EVERY OTHER
HOLE IN THE OUTER ROW
OF HOLES IN THE DIFF
GEAR. LUBE THEM WITH A
LITTLE OIL OR SILICONE.
STEP 13
ASSEMBLE THE DIFF: 1ST DRIVE RING,
GEAR, 2ND DRIVE RING, ALUM. ADAPTOR, HUB, THIN
STEEL WASHER, BLUE BALL CAGE, THICK STEEL
WASHER, CONE WASHER, AND THE RED LOCKNUT.
TIGHTEN THE NUT CAREFULLY, MAKING SURE THAT
THE DRIVE RINGS ARE IN PLACE. CHECK THE TIGHT-
NESS BY HOLDING BOTH HUBS AND TURNING THE
GEAR WITH YOUR THUMB. IT SHOULD NOT SLIP TOO
EASILY. YOU CAN DO YOUR FINAL ADJUSTMENT
WHEN YOU RUN THE CAR.
STEP 14
INSTALL THE MOTOR YOU HAVE PUR-
CHASED WITH M3 SCREWS AND WASHERS FROM
BAG C1B. YOU CAN MOUNT IT IN FRONT OR BEHIND
THE REAR AXLE TO GET THE DESIRED WEIGHT
DISTRIBUTION. INSTALL THE GEAR WITH THE SET-
SCREW AND MAKE SURE IT LINES UP WITH THE
DIFF GEAR. SLIDE THE MOTOR BACK UNTIL YOU
HAVE A VERY SMALL AMOUNT OF PLAY BETWEEN
THE GEARS. TIGHTEN THE MOTOR SCREWS , TURN
THE AXLE A COUPLE OF TIMES, CHECK THE GEAR
MESH , AND READJUST IF NECESSARY.
STEP15
INSTALL YOUR STEERING SERVO WITH
FOAM TAPE PROVIDED. WE SHOW IT UNDER THE
SERVO TRAY, BUT YOU CAN MOUNT IT ON TOP OF
THE TRAY OR ON THE FRONT AXLE PLATE WITH THE
OUTPUT TO THE REAR IF YOU WANT TO LEAVE
MORE ROOM TO MOVE YOUR BATTERY PACK FOR-
WARD TO INCREASE THE WEIGHT ON THE FRONT
END OF THE CAR. IF YOU MOUNT IT ON THE FRONT
AXLE PLATE, YOU MAY HAVE TO PUT BENDS IN THE
LINKAGE WIRES TO GET CLEARANCE THROUGH THE
CHASSIS SIDES. INSTALL THE LINK RODS FROM BAG
2B AND ATTACH TOGETHER WITH THE TWO COL-
LARS AND SET SCREWS. MAKE SURE THE AXLES
ARE POINTED STRAIGHT OUT. YOU CAN RECHECK
THE ALIGNMENT AFTER YOU INSTALL THE FRONT
TIRES.
