XT9 TECH TIPS
Before filling the differentials with oil we suggest that you first check gear mesh as below. 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.
For easier gear mesh adjustments, optional S13 x 0.2
shims are used. These shims can be placed behind the
bearing.

THE LOCATION OF THE SHIM(S) DEPENDS ON WHETHER YOU ARE TRYING TO CLOSE OR OPEN THE 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 pINS 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 and comfortable drive pin replacements use
#106000 HUDY Drive Pin Replacement Tool.
To replace the worn pins use only
premium HUDY drive pins #106050.
GRAPHITE PARTS PROTECTION
TIP
Follow this tech tip to protect the graphite parts.
Fine sandpaper
Use fine sandpaper
to sand smooth the
edges of all graphite
parts.
Apply CA glue to all edges
of the graphite parts.
Protect all XT9
Graphite Parts:
• Front shock tower
• Rear shock tower
• Steering plate
• Upper plate
• Center diff mounting plate
Do not use drive shafts when
the pins are worn.
Press out the worn pins.
Press in new pins and
regularly inspect for wear.
