REMOVE THE SERVO
;e steps required to remove the servo will vary from vehicle
to vehicle, and you may need to disassemble a receiver box
to unplug the servo from the receiver. Be sure to keep track of what
goes where. Most brands o;er exploded views that you can download
online (or just consult your manual). ;ese are invaluable aids in
getting all the pieces back where they belong.
Servos are held together with
four screws, usually with a small
Phillips head. You can remove the
screws all the way, but you don’t need
to remove the bottom servo plate;
we’ll just be working with the top.
Before removing the top piece, note
if there is an O-ring between the two
upper parts of the case. If so, set it
aside. Now, with the servo standing
upright on your work surface, press
down on the servo output shaft while
simultaneously pulling up on the top
part of the servo case. You should
be able to remove the top part of the
case while leaving the gear assembly
intact on the servo.
Preventing Future Gear Blowouts
Always use a servo-saver to spare your steering servo from major
jolts. Servo-savers may be built into the steering bellcranks or
installed directly on the servo-saver itself. ;e bellcrank type can
become jammed with dirt, reducing its e;ectiveness; disassemble,
clean, and lube if necessary. If you model does not have a servo-saver, Kimbrough is the go-to brand for servo-mounted units.
Most vehicles don’t require a lot of disassembly to access the steering servo. Removing
four screws usually does the trick.
Most servos are held
together by four screws
installed from the
bottom, but some also
have screws on top.
To remove the top of
the servo, press down
on the shaft as you pull
up on the case.
If you have a waterproof servo, there may be a
gasket between the case halves, and O-rings on
the screws. Save these for reassembly.
;is Traxxas Slash has a servo-mounted servo-saver. If the servo
is overloaded, the spring-loaded
’saver will absorb the extra stress.
Kimbrough o ;ers a variety of servo-savers
to suit all vehicle scales. ;e three inserts are
adapters to suit di;erent servo brands.
