--------------- END SUPPLEMENT ---------------

A number of changes were made to the drive shaft groups on TH63, TH82, and TH83 Telehandlers to improve reliability and life. Replacement axles for RT80 Telescopic Material Handlers may have these drive shaft group changes also.

The changes are included in replacement axles for RT80 (1GJ) but the parts do not directly interchange with previous axles. Parts will continue to be serviced for previous axles.

The improved drive shaft groups are effective as shown in Chart 1.
