When Removing the Outer Seal, It Is Necessary to Remove the Front Wheel from the Front Caster Fork - Loosen and Remove the Lock Nut & Bolt and Remove the Caster Fork Wheel. When Removing the Outer Seal - After Seal Has Been Remove the Wheel Hub Bearings are 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 Verify When Assembling - That the 606753P Bearing & Race is Not Worn, Contains a Rough Surface or Damaged in Any Way Before Installing a New Seal - Be Mindful the Race is the Smooth Alloy Surface that the Rollers on Bearing Will Travel Across - Damaged Races Can Prematurely Wear out the Roller Bearings and Vice Versus (606753P Bearing Races are a Press/Friction Fit and Will Require them to be Pressed or Pounded Out of the Caster Fork Tube - if Installing a New Bearing & Race - it Is Recommended to Utilize a Bearing Race Installation Tool to Ensure No Damage Occur to the Inner Race Surface). Be Sure to Pack the Voided Areas where Grease Had Been Lost inside the Caster Fork Wheel Hub, In the Bearing Rollers & Apply a Grease Layer to the Race Surface - This will Ensures the Bearing Rollers and Race Surface Don't Overheat from Lack of Lubrication - Be Sure to Apply Grease using the Grease Zirk on the Wheel Hub After Installation to Compress Grease Into The Voided Areas of the Wheel Hub and Wheel Bearings. When Re-Installing the Front Wheels it is Important to Note: Over Tightening the Tapered Bearing into the Bearing Race when Re-Assembling the Wheel on the Caster Fork Could Reduce the Rotation of the Caster Fork and Wheel as Well as Affect Drive Track and Cause Pre-Mature Wear on the Bearing Rollers and Race - Be Sure to Snug The Nut And Bolt Tight With a Wrench or Socket (Front Wheels) and Back it Off Only Until the Wheel and Bearings Rotates Freely Without any Seemingly Abnormal Drag.
