TT-915 - CASTER & DRIVE WHEEL ALIGNMENT Models Effected: All Operator Aboard Extractors

The Importance of Proper Caster and Drive Wheel Alignment


Improper wheel alignment can result in abnormal wheel tread wear, drive wheel assembly bearing failure, as well as guidance arm bearing failure. In order to ensure proper tracking of both the rigid mounted idler casters and the drive assemblies, the alignment must be validated any time an idler caster or drive assembly is removed or replaced.


Casters and drive wheel assemblies should be aligned within 1/16”. Refer to Technical Procedure TP-611 for complete alignment procedure.
