blade screwdriver from the inner front hinge pins (104).Pull on the front
hinge pin brace (50) to remove the two inner front hinge pins (104). Be
careful not to loose the e-clips.

3. (Diagram 2) Loosen the 3mm set screw (K) from the bulkhead (51).
Remove the bulkhead/chassis hinge pin (103).

4. (Diagram 2) Remove the four 4-40x3/4" screws (E) from the upper
plate (52). Rotate the front assembly out of the way.

5. (Diagram 2) Remove the two 4-40x3/8" screws (C) from the servo
brace (56) and set them aside.

6. (Diagram 2) Remove the two 4-40x5/16" screws (B) located on the
bottom of the chassis that hold the servo mounts (6) to the chassis. Lift
the servo saver assembly off at the same time as the servo.

7. Unplug the speed control from the receiver and remove the receiver
from the chassis with the steering servo still plugged in. This will help
during the re-assembly process.

8. (Diagram 2) Carefully pry out the two brass bushing (105) from the
front of the chassis (1) using a hex wrench included with the kit.

9. Disconnect the motor leads from the speed control and remove the
speed control from the rear shock tower (40).

shock tower (40).

11. (Diagram 1) Remove the four 4-40x3/8" screws (C) from the rear
chassis plate (41).

The chassis (1) should be free from all other parts at this point.

INSTALL NEW CHASSIS

1. (Diagram 1) Slide the rear chassis plate (41) and the chassis (1)

together and re-install the four 4-40x3/8" screws (C).

2. (Diagram 1) Attach the rear shock tower (40) to the chassis (1), using
the four 4-40x1/2" screws (D).The screws should pass through the rear
shock tower (40), chassis (1) and thread into the transmission brace (42).

3. (Diagram 2) Install the two brass bushings (105) into the chassis.

4. (Diagram 2) Connect the chassis (1) with the front bulkhead (51) and

install the bulkhead/chassis hinge pin (103) and tighten the 3mm set
screw (K).

5. Install the steering servo into the chassis with the two 4-40x5/16"
screws (B). Note: There are two sets of holes in the bottom of the servo
mounts (6).Make sure you install the scre ws into the same hole they came
out of.(Refer to page 9 of the instruction manual included with the kit).

6. Install the servo saver assembly onto the chassis.

7. (Diagram 2) Install the servo brace (56) onto the chassis using the two

4-40x3/8" screws (C).

8. (Diagram 2 & 3) Rotate the upper plate (52) onto the chassis. Make sure
the metal pins (99 & 100) of the servo saver assembly are properly seated
into the brass bushings (105) located in both the chassis and the upper plate.
Attach the upper plate to the chassis using the four 4-40x3/4" screws (E).

9. (Diagram 2) Re-install the front suspension arms (38 & 39) to the front
bulkhead using the inner hinge pins (104) and the front hinge pin brace
(50). Secure the hinge pins by installing the two 2.5mm e-clips (S) onto
the ends of the two hinge pins (104).

10. (Diagram 2) Attach the front bumper (2) using the four 4-40x5/16"
screws (B).

11. Install the receiver to the chassis. You can try to remove double-sided
foam block used on the old chassis or use several layers of new (not
included) double-sided foam tape to obtain the same elevation so that the
receiver will clear the rails on the chassis. DO NOT cut the rails on the

chassis for the receiver to fit,as this will drastically weaken the chassis.

12. Install the electronic speed control to the rear shock tower using

double-sided foam tape. Re-connect the servo lead to the receiver and
the motor leads to the motor wires.

REMOVE OLD BULKHEAD

screwdriver from the inner hinge pins (104). Pull on the front hinge pin
brace (50) to remove the two inner hinge pins (104).

3. Loosen the 3mm set screw (K) from the under side of the bulkhead
(51). Remove the bulkhead/chassis hinge pin (103).

4. Remove the four 4-40x3/8" screws (C) that attach the front shock tow er
(49) to the front bulkhead (51) and rotate the shock tower out of the way.

5. Remove the two 4-40x5/16" screws (B) that attach the upper plate to
the front bulkhead.

The front bulkhead should be free from all of the other parts at this point.

INSTALL NEW BULKHEAD
(Refer to Diagram 2)

1. Connect the front bulkhead (51) to the chassis (1) and install the

bulkhead/chassis hinge pin (103) and tighten the 3mm set screw (K).

and into the bulkhead (51).

3. Use the four 4-40x3/8"screws (C) to re-attach the front shock tower
(49) to the bulkhead (51).
