How To Order

Remove the bronze arbor bushing located in the outer support.
Measure the large diameter of the bronze bushing and find the corresponding diameter in Column D (see Specification Charts) across from the arbor diameter required for the particular make of the machine.
Column 1 (see Specification Charts) specifies the correct bushing number for each combination of "D" and "A".
For machines not listed or for intermediate support arms, specify also the small diameter and thickness of the support arm for determining the length and degree of taper for the bushing.
