Assembly Notes
WHEN INSTALLING 606712 BEARING KIT:
-
Take Pictures to Document Order of Components When Removing Caster Components - Refer to The Diagrams Above in the Image Section - Or Refer to Caster Fork Installations Directions for the Correct Caster Fork for your Unit for Assembly Help if Needed.
-
When replacing the 606713 Bearing Races it is Important to Note that They are a Press/Friction Fit and Will Require them to be Pressed or Pounded Out of the Caster Fork Tube - When Installing a New 606713 Race it Is Recommended to Utilize a Bearing Race Installation Tool to Ensure No Damage Occur to the Inner Race Surface.
- Pack the Rollers on the Bearing with Grease and Spread Some Along the Outer 606713 Race where the Bearing Rollers Travel as Well as Fill & Pack the Voided Areas where nothing is 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.
- When Assembling Race & Bearings in Caster Fork Tubes - Be Sure to Assemble the Race with the Thicker Section Installed First into the Caster Tube so the Small Side of Bearing (Tapered Side) Inserts into the Caster Fork Tube First and Sits into the Bearing Race Properly (Should Fit Like a Glove or Mate).
-
When Assembling the Washer on Caster Fork Ass. - Be Sure to Install the Cup on the Washers as Installed in the Images Below - Requires Three Washers Per Caster Axle.

- Over Tightening the Tapered Bearing into the Bearing Race when Re-Assembling 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 Refer to The Correct Caster Fork Directions For your Unit for Complete Caster Fork Installations as well as Caster Fork Fastener Torque Specifications.
- For an Individual Caster (Bearing, Race, Seal Reference) Refer to the Listed Parts Reference Above.
