BRAKE DRUM CROSS REFERENCE SECTION
43
¹When replacing existing drums in the field, ensure adequate wheel stud thread engagement.
²Webb brake drums are interchangeable with Motor Wheel brake drums; however, in some Motor Wheel assemblies the stud may have to be
changed to accommodate the thicker backplate of the Webb brake drum. This is necessary when only the brake drum is being replaced.
**Will become obsolete when current inventory is depleted. Call for availability - if purchased, parts are non-returnable.
