1. Differential
The Scalpel differential works great with the grease contained in the Scalpel Box. But there are some points to be
considered, to ensure optimal function.
a. Be careful not apply too much differential grease during assembly. Too much grease impairs the operation
and smoothness of the diff. Too much grease also attracts too much dust in the differential, which leads to
excessive wear to the diff.
b. Look at the correct installation direction of the disk shims. Incorrect installation of the disk shims limits the
adjustability of the differential.
c. Tighten the differential nut carefully, if the differential nut is to firmly tightened, the differential will not operate
effectively.
d. With stronger motors (Brushless) it is recommend to tighten the differential a little bit more otherwise the rear
tires will break loose when accelerating.
2. Front wheels
Please check during assembly that the front wheels spin smoothly. Loosen the wheel nut slightly if the front wheels are
not spinning smoothly.
3. Front knuckles
Due to the production process some items may not fit together properly. The front knuckles may be a little loose, in order
to get the fit just right follow the following steps.
a. Degrease the metal parts (Wheel axle and the socket for steering axle)
b. Use red thread lock on the outside surface of the socket for the steering axle.
c. Use red thread lock in the cross hole of the wheel axle.
d. Now install the wheel axle and the socket for the steering axle with the front knuckles.
e. Carefully remove any excess thread lock fluid from all places on the knuckle.
f. Wait, until the thread lock is completely hardened.
g. Now assemble the steering arm onto your Scalpel and test to make sure the steering is moving freely.
