The T85650 Barring Arbor is needed in the new Evolution Engines that are not equipped with a barring gear box. The arbor is installed into the gear cover and a T22040 or T16050EVO Barring Over Tool is used to power the arbor. Caution: When the barring operation is complete the barring arbor must be removed and the gear cover reassembled.
The shear pin used with this barring arbor is the same pin used with the GE FDL arbor.
Part number for the shear pin is T58440P
