Lubrication Intervals
IMPORTANT: The recommended service intervals are based on normal
conditions; severe or unusual conditions may require more frequent
lubrication.
Perform each lubrication and service procedure at the beginning and end of each
season.
Clean grease fittings before using grease gun, to avoid injecting dirt and grit into
the bearing. Replace any lost or broken fittings immediately. If a fitting fails to
take grease, remove and clean thoroughly, replace fitting if necessary. Also
check for failure of adjoining parts.
BEARING REPLACEMENT INSTALLATION
1. When assembling the spoke wheels, bearing assembly and hubcap, be
sure to align the grease transfer hole in the spoke wheel with the groove in
the hubcap and hole in the hub to allow grease passage.
2. Assemble the wheels, hubs and caps.
3. Grease the wheel/hub/bearing assembly.
