To keep downtime to a minimum, it is desirable to have on hand certain repair parts. We recommend that you stock one (pair or set) of each

part indicated by a bullet (•) for every four tools in service.

‡ Whenever a new Angle Arbor Housing is installed, select the correct Nameplate from the Nameplate Kit (43A) and attach it to the Housing

with the Nameplate screws (43B).

† Indicates Tune-up Kit part.

# Early models of these Grinders had Rotors and Controller Assemblies with left-hand threads. If you have a model with left-hand threads,

contact Ingersoll Rand when ordering replacement parts.
