Servicing Zero Pro Shock Absorbers (Ski Shock) - Arctic Cat 2014 SNO PRO 500 Operator's Manual

SERVICING ZERO PRO SHOCK
ABSORBERS (Ski Shock)
This procedure shows the proper method for servicing
the ski shock absorbers.
! WARNING
Before starting, read through all of these instructions
first to become familiar with the procedure. Make sure
the work area is clean and all of the necessary tools
are available. These shocks contain high pressure
nitrogen gas. Always use proper safety equipment
such as latex gloves and safety glasses when working
on shock absorbers.
Disassembling
1. Remove the spacers and O-rings from the eyelets.
2. Clean the entire shock assembly with soapy water.
Dry the shock assembly with compressed air.
CAUTION
Use a soft-bristle brush to remove as much dirt and
debris as possible. Do not pressure wash the shock
as this can force water and debris inside causing dam-
age to the seals.
! WARNING
When using compressed air to dry components,
always wear safety glasses.
NOTE: If compressed air is not available, use
clean towel to dry the shock assembly.
3. Using a 3/32-in. hex key, remove the button-head
screw from the air valve in the shock body.
4. Clamp an inflation needle in a vise; then insert the
needle squarely into center of the nitrogen valve to
release the pressure.
! WARNING
Point the air valve away from face and body to avoid
injury when discharging or charging the shock.
5. When the shock is fully discharged, pull the needle
away from the reservoir in a straight, smooth
motion.
NOTE: At this point, inspect the FAV3 nitrogen
valve for signs of wear such as holes on the face
of the pellet. Replace if necessary.
6. Clamp the body and eyelet securely in a soft-
jawed vise with the shaft side up.
7. Using a 1 3/8-in. wrench, loosen and unscrew the
bearing assembly from the shock body.
8. Remove the shaft assembly from the body tube
and place it on a clean, lint-free rag or towel.
9. Remove the shock from the vise and pour shock
oil from body tube into a proper disposal con-
tainer. DO NOT REUSE OLD SHOCK OIL.
10. Using Gas Shock Retaining Blocks (p/n 0644-
486), secure the shock body in the vise taking care
not to crush the shock body; then using a propane
torch, heat the body cap to soften the Loctite.
Using a crescent wrench or cap socket, remove the
body cap.
11. Using an IFP depth setting tool, remove the IFP
from the shock body. Place the IFP on a clean, lint-
free rag or towel.
