All-Wheel Retrofitting Set
Item no. 23 59 28
Item no. 23 71 97
Item no. 51 70 44
Intended Use
The product serves to retrofit model vehicles of the Carbon-Fighter series from rear-wheel
drive (2WD) to four-wheel drive (4WD). Since the series has several models, three different
kits for retrofitting are available as well. Additionally, different components may have been
installed during model maintenance (e.g. differentials).
Therefore, the present installation instructions only show the general systematic installation
of the 4WD retrofitting kit. It only serves to illustrate the required steps.
The indicated work steps are identical for all models. The number and position of the affected
screws, however, differs and must be individually considered according to model and own
discretion.
For more information on which retrofitting kit can be installed in which model, see our
catalogues or the respective product at www.conrad.com.

Installation of the 4WD Retrofitting Kit
Figures 1 and 2:
Different differentials have been installed in the Carbon series vehicles. The
retrofitting kit Conrad item no. 237197 can only be installed in the models
in which the lower transverse links of the front axle (figure 1, item 3) are screwed to
the chassis. Figure 1 shows the top differential housing (1) and the lower differential
housing (2).
The retrofitting kit Conrad item no. 517044 can only be installed in the models in
which the lower transverse links of the front axle are screwed to the front (empty)
differential housing (figure 2). Figure 2 shows the top differential housing (1) and the
lower differential housing (2) with screwed-on transverse links (3).
Work steps for figure 3:
• Remove the car body + over-roll bars from the model.
• Remove the air filter (1) and the carburettor (2), disconnect the throttle linkage.
• Remove the servo lever of the steering servo (3).
• Loosen the hexagon socket screw of the braking mechanics (4) and remove the braking
lever.
• Remove the front and rear metal plates (5 and 6).
Work steps for figure 4:
• Remove any attachment screws of the RC box (1) that may still be present at the top.
• Remove the screws of both steering knuckles (2).
• Remove the skirting protection (3).
Work steps for figure 5:
• Remove all screws at the bottom of the chassis that serve to attach the RC box (1).
• Remove all screws at the bottom of the chassis that serve to attach the front differential. If
the lower transverse links of the front axle are attached to the chassis, they must be removed
as well.
Work steps for figure 6:
• Remove the complete front axle unit from the chassis (1).
• Install the shaft tappet from the set on the output shaft (2). Use threadlocker varnish for the
attachment screw of the shaft tappet.
Work steps for figures 7, 8, 9:
• Place the differential (1) from the set into the upper differential housing. The large cogwheel
(2) must be placed so that the cogwheel can run freely in the corresponding recess of the
chassis plate (also see figure 9 or individual placement in your model).
• Insert the small cogwheel (3) from the set into the differential housing.
• Apply grease on the cogwheels generously and fill the side at the large cogwheel until
saturated (4). The differential housing must be filled to about half in this place to warrant a
lasting lubrication film.
• Figure 7 shows assembly of the differential into the upper differential housing. Figure 8
shows the installed differential with attached lower differential housing (the illustration shows
the differential version with installed transverse links). Figure 9 shows an example of an
indentation of the chassis plate in the area of the front differential.
Work steps for figure 10:
• Install the output shaft from the set (1) between the shaft tappets (2).
• Screw the front axle (3) to the chassis. Ensure that assembly does not cause tension in the
chassis and the drive strain (shaft).
Work steps for figure 11:
• Disassemble the front wheels.
• Remove the wheel tappets (1) from both axles (2). The tappet has two different sides;
therefore, note how the tappet is installed before disassembling it!
• Remove the top and bottom screws of of both steering knuckles (3).
• Remove the two axles (2) from the steering knuckles.
Work steps for figure 12:
• Install the two drive shafts from the kit (1) in the steering knuckles (2) and push the drive
shafts into the tappets of the differential (3).
• Screw on the steering knuckles again (4).
• Install the wheel tappets on the shafts (5). Observe correct installation of the tappets (see
„Work steps for figure 11).
• Install the wheels again.
Conversion from rear-wheel drive (2WD) to all-wheel drive (4WD) hereby is completed.
Install the RC box, carburettor and air filter again in reverse order. Make sure that the
components are placed correctly and firmly.
After installation of the carburettor, the movability of the choke lever must be verified. If the
choke lever cannot be operated or if it is difficult to operate, the carburettor must be loosened
and centred again. Check that the remote control is working correctly before every operation.
