XB8E TECH TIPS
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:
TO CLOSE A WIDE GAP
TO OPEN A NARROW GAP

TIP
Tighten screw until pivot ball is tight
against block.
Lift ball joint until it snaps into place over
pivot ball. Ball joint should move freely.
The finished joint.
Loosen and remove screw.
INSTALLING PIVOT BALLS INTO COMPOSITE BALL-JOINTS
Place the pivot ball on the ball joint
and use a screw to tighten it to an
engine mount or some other part.
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.
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

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.
