The T58440 EFI Barring Arbor is for newer EFI engines that are not equipped with barring gear boxes. The arbor is installed in the new gear cover and secured. The T22040 Barring Over Tool is then used to power the barring arbor, and the operation is essentially the same as on older units.
Replacement shear pins are available: T58440P
CAUTION: After the barring operation is complete, the barring arbor must be removed from the engine and the gear cover reassembled.
