SHOCK ABSORBER MAINTENANCE

It may be necessary to replace the silicone oil in the shock absorbers every 40 runs (depends on how you drive and the type of terrain you drive on).

ALWAYS USE 100% SILICONE OIL

• Fill the shock with silicone oil.
• Move the piston up&down (3-4x) to release the air bubbles in the silicone oil.
• Pull the Shock shaft down and wait until the bubbles rise to the surface.
• Screw in the shock absorb-er cap at 50%.
• Gently move the piston  in upper position, the oil excess will flow out.
• Now tighten the cap fully but not too much otherwise the membrane will be deformed.

DIFFERENTIAL MAINTENANCE

It may be necessary to replace the silicone oil every 50 runs (depends on how you drive and the type of terrain you drive on).

1. Remove the screws under the chassis.

2. Remove the bumper.

3. Remove the 2 shock absorbers fixing screws.

4. Loosen the anti-roll bar ball.
   Remove the 2 upper fixing screws from the differential cover.

5. Extract the differential

6. Unscrew the differential. (4x F/H M3x10)

7. Drain the silicone oil from the differential.

8. Fill with new silicone oil (75% capacity max.)
   Perform the same maintenance operation for the Centre and Rear differentials.

REMOVING THE CENTRE DIFFERENTIAL

It may be necessary to replace the silicone oil every 50 runs (depends on how you drive and the type of terrain you drive on).

• Remove 4 screws.
• Release the Centre Diff Plate Cover.
• Extract the differential and follow the maintenance instruction on the DIFFERENTIAL MAINTENANCE section.

GEAR RATIO

MOTOR PINION MOD1.0
High-performance 13T tooth pinion gear, manufactured from special steel for toughness and durability with precise tolerances and assures unparalleled concentricity. Created on a special gear machine, all pinions feature ultra- precise tooth shaping and ultra-true running for vibration-free operation. Each pinion is marked with the tooth number for easy and quick identification.

• Special hardened steel –
• CNC cut teeth for perfect teeth shape and concentricity
• Fits all cars with MOD1 gears (1/8 Scale)
• For 5.0mm motor shafts

Note: The speed indicated in the table is a theoretical speed for information purposes. The real speed varies according to the type of terrain, electronic
equipment, atmospheric conditions and other driving parameters.

GEAR MESH ADJUSTMENT

If the gear mesh is not correct, you wear out the spur gear prematurely, the transmission will make noise, give unnecessary load on the
motor (higher consumption, heating of the transmission).

1. Loosen the screws

2. Insert the paper strip.

3. Push the motor against the spur gear

4. Turn the spur gear to run the paper through the teeth. Stop when the paper is in the middle.
   Make sure that the motor pinion is against the  spur gear

5. Maintain and tighten the fixing screws
