Older models (all black parts) may experience some slipper hub and
battery box rubbing and may need the battery box replaced with
part #4925A.
Remove Transmission
1. Snip the zip tie located around the air filter
base, and remove the air filter from the
carburetor. Loosen the grub screw at the
top of the brake cam, and then remove the
brake rod from the brake cam (A).
2. Position the throttle servo
horn perpendicular to
the chassis (B) and then
gently lift the throttle
servo horn off of the
servo.
Note
: Be careful
not to move the position
of the servo output shaft. This must
remain in the same position for
re-installation of the servo horn (C).
3. Next, pop the shift linkage off of the shift
fork, and then disconnect the throttle
linkage wire from the throttle bell crank (D).
4. Now, turn the truck upside down to
access the rear driveshaft. Remove the
yoke pin from the rear output yoke on
the transmission. Pull the output yoke
from the shaft, and then push it to the
rear to clear the shaft during removal (E).
5. While holding the
transmission with one
hand, remove the eight
transmission screws
located in the chassis
braces. Remove the
transmission from the
chassis (F & G).
Replace Slipper Shaft
1. Start by removing the stock spur gear and slipper assembly.
Remove the slipper nut, and then slide the entire slipper
assembly off of the shaft (H & I). Next, Remove the seven
transmission screws from the transmission case, and then gently
separate the two transmission halves (J).
2. Remove the stock slipper shaft (with gear) from the transmission
case (this will not be reused), and replace it with the new slipper
shaft and gear (included) (K).
3. Connect the two
transmission halves
together. Make sure
that all gears and shafts
are aligned correctly.
Secure the transmission
case with the seven
transmission screws (L).
Slipper Clutch Installation
1. Insert the drive pin
(included) into the hole
located in the slipper
shaft. Next, slide the
slipper hub onto the
slipper shaft and key
the pin into the slot of
the slipper hub until the pin is locked into the hub. Follow the
slipper hub with the steel slipper disc, and then key it into place
on the hub (M & N).
2. Locate the three friction
pads (included), and then
press them onto the pins
of the pressure plate.
Apply even pressure to
each pad to make sure
they are flat against the plate (O & P).
3. Next, insert the 5x11mm bearing (included) into the middle of
the spur gear (Q). Now, connect the spur gear and the pressure
plate together by lining up the holes in the pressure plate with
the holes in the spur gear, and then press them together (R).
Make sure that the gear is flat against the pressure plate, and then
secure the gear to the slipper plate with the three flat head spur
gear screws (included) (S).
4. Slide the spur gear and pressure plate assembly
onto the slipper shaft from the transmission
and against the slipper ring (T).
5. Next, slide the two bevel washers (included)
onto the slipper shaft (see diagram for
correct orientation).
Important
: Pay close
attention to the orientation of the bevel
washers. Correct orientation of the bevel
washers is critical to proper performance
of the slipper and to avoid damaged to the
sealed bearing (U and Fig. A).
6. Thread the slipper nut onto the slipper shaft
until it provides a slight amount of pressure
against the bevel washers.
Tip
: To lock the
shaft when starting the slipper nut, gently
slide the shaft of a 2mm hex driver into one
of the cooling fins of the slipper hub (V).
Do not force the hex driver into the fins.
This may damage the hub.
