Collar removing tools After the snap ring has been removed, the track roller and collar can be disassembled from the shaft by using the collar removing tools as shown below.


Sizing discs After welding the roller, it is often necessary to restore the bore to its original size. Now expensive boring equipment and labor is not needed. Sizing discs forced through the roller bores restore them to original dimensions in a few minutes.
