RAIL SLIDERS
Wear Limit
Replace sliders when wear exceeds notch. If sliders look
“wavy” in appearance, check and adjust track tension or
consider adding more bogie wheels.
Removal/Installation
1. Raise the snowmobile off the ground using a
snowmobile lift.
2. Remove front rail slider retaining
bolt, located at the
rail tip.
3. Use a block of wood or a drift punch and hammer to
dr
ive the slider rearward off the slide rail.
4. With the rail slider at room temperature, install a new
rail slider by rev
ersing steps 1 - 3.
NOTE: Lightly coat rail slider track clip area with a
lub
ricant such as LPS2 or WD-40 to ease installation.
Break-In
After installing new rail sliders they must be “broken-in” for
longer life and better wear patterns. When performing the
break-in procedure, ride the sled on a surface that has
adequate snow conditions with deeper snow nearby. Run
the sled on the adequate snow surface and dip into the
deeper snow every so often.
INDY 121 Optional Bogie Wheels
INDY 121 rear suspension operation in sustained low
snow conditions may cause increased rail slider wear. Rail
slider longevity can be increased by installing an
additional set of bogie wheel assemblies as shown on
page 8.35. Order the following parts:
• 7542324 QTY.4 - Nuts
• 5631446 QTY. 2 - Wheel Mount
