• Use HUDY Bearing Grease to regularly lubricate grease-bearing ball-bearings.
• Use HUDY Bearing Oil to lubricate the bearings of the steering system.
• Use HUDY Bearing Grease to regularly lubricate the clutch bearings.
SUSpENSION & DRIVETRAIN MAINTENANcE
• Check suspension for free movement during building and operation, and especially after
running and if you have crashed the car. If the suspension does not move freely, use the
appropriate HUDY Arm Reamer to clean and resize the holes of the suspension arms.
• Regularly check the drive shaft pins (both side and center) and if they show any wear
must be immediately replaced by new pins. If the car is run with worn pins, excessive
wear on the diff outdrives will result. The 106000 HUDY Drive Pin Replacement Tool (for
3mm Pins) is a compact, rugged multi-use tool set for replacing 3mm drive pins in drive
shafts. Use the HUDY replacement drive shaft pins 3x14 (#106050).
• Regularly inspect and replace the connecting pins which connect the center drive shafts
with the pinion gear, and also the pins that connect the wheel drive shafts with wheel
axles. Use HUDY Graphite Grease to lubricate the drive shaft connecting joints and the
diff gears.
• Pivot balls and ball-joints will naturally wear for some time and will generate play. If
there is too much play the pivot balls and ball joints need to be replaced.
• If the car is run in wet conditions, apply WD-40® on all drivetrain parts before the run.
After the run, clean and dry the parts again.
HUDY SpRING STEEl™
The HUDY Spring Steel™ used in the car is the strongest and most durable steel material on the RC market. While items made from HUDY Spring Steel™ are still subject to wear, the
lifespan is considerably longer than any other material. As parts made from HUDY Spring Steel™ wear, the brown color will after some time “go down” but it will not affect the strength of
the material. The brown color is only a surface treatment and if the brown color will wear the durability of the part will be still strong.
clUTcH BEARINGS
To prolong the lifespan of the clutch bearings, they must be regularly cleaned and lubricated (preferably after each run) using a
high-quality grease such as HUDY Bearing Grease. However, after some time the clutch bearings must be replaced with new ones.
