Assembly Notes
WHEN CHANGING 606714 GREASE SEAL:
- When Removing the Lower Seal, It Is Necessary to Remove the Dust Cap - Loosen and Remove the Lock Nut and Remove the Caster Fork.
- When Removing the Lower Seal - After Seal Has Been Remove the Lower Bearing is Prone to Fall out - If this Happens Make Sure It is Re-Assembled with the Taper Fitting into the Outer Bearing Race Taper Properly (the Roller Bearing & the Bearing Race Tapers Should Mate) Before Installing the New Seal.
- Be Sure to Pack the Voided Areas where Grease Had Been Lost inside the Caster Fork Tubing - this will Ensures the Bearing Rollers and Race Surface Don't Overheat from Lack of Lubrication - If Necessary, Remove the Grease Plug After Installing the Caster Fork and Install a 1/4" Grease Zirk to Install Grease Into The Voided Areas of the Caster Tubing.
