Adjustment; Lift Cylinder - Snorkel SL26RTE Parts & Service Manual

SERVICE AND REPAIR

ADJUSTMENT

1. Disconnect the cylinder rod ends (if connected).
2. Operate steering so that both ends of the cylinder rod are equal in length therefore within 0.8
mm (1/32 inch).
3. Position both tyres so that they are parallel with the frame, with each other and with the rear
wheels.
4. Adjust rod ends until they align with the holes on the steering linkage bars.
5. Re-install the bolts through the steering linkage bars and rod ends. Tighten the jam nuts on
the rod ends and all hardware.
6. When properly adjusted, the wheels must turn the same amount in each direction. The steer-
ing stops must make contact with each side at the same time.
