14.Reinstall the seal guards over the wheel hub and insert wheel into caster fork. Reinstall caster bolt and tighten nut fully.
Important: To prevent seal and bearing damage, check the bearing adjustment often. Spin the caster tire. The tire should not spin freely (more than 1 or 2 revolutions) or have any side play. If the wheel spins freely, adjust torque on spacer nut until there is a slight amount of drag. Reapply thread locking adhesive.
Remove Engine Shrouds and Clean Cooling Fins
Service Interval: Every 80 hours
1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.
