At the beginning of each section is an exploded view of the parts to be assembled. There is also a list of all the parts and part
numbers that are related to the assembly of that section. The part descriptions are color-coded to make it easier for you to
identify the source of a part. Here are what the different colors mean:
STYLE A - indicates parts that are included in the bag marked for the section.
STYLE B - indicates parts that are included in the box.
STYLE C - indicates parts that are already assembled from previous steps.
XB8 TECH TIPS
TO CLOSE A WIDE GAP
TO OPEN A NARROW GAP
If there is too much or too little diff side play, this may create non-optimal gear mesh between the diff gear and the pinion drive gear. This
is easily resolved by inserting 1 or 2 of the included thin shims behind a diff outdrive ball-bearing, depending on how much play there is.
FRONT & REAR DIFF GEAR MESH ADJUSTMENT
THE LOCATION OF THE SHIM(S) DEPENDS ON WHETHER YOU ARE TRYING TO CLOSE OR OPEN THE GAP:
TIP
To CLOSE a wide gap:
add 1 or 2 shims
against diff spur gear
To OPEN a narrow gap:
add 1 or 2 shims on the
other side of the diff, away
from spur gear

DRIVE SHAFT PIN SERVICING
TIP
To enjoy the longest possible lifespan of the drive shafts and diff outdrives, it is extremely important to properly service the drive shaft pins.
Inspect the pins after every 3 hours of runtime. If the pins show any wear, replace them with new pins.
For easy drive pin replacements use #106000
HUDY Drive Pin Replacement Tool.
To replace the worn pins use only
premium HUDY drive pins #106050.
Do not use drive shafts
when the pins are worn.
Press out the worn pins.
Press in new pins and
regularly inspect for wear.
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.
CHECK GEAR MESH AND DIFF PLAY ONLY AFTER THE ENTIRE GEARBOX IS MOUNTED TOGETHER WITH THE SUSPENSION HOLDERS ON THE CHASSIS.
ALL PARTS ARE DESIGNED TO HAVE CERTAIN PLAY AND IT IS ALL DESIGNED BY PURPOSE.
