Application and Service Notes

Eaton warranty guideline RWRG0032 identifies 4306520 as the replacement output nut used after correcting a loose output-shaft condition and specifies 650–700 lb-ft in that procedure. That torque must not be treated as universal for every transmission build without confirming the applicable service manual and output configuration.

Confirm the complete transmission model, serial number, output shaft, yoke or flange, nut thread, and original nut number before ordering. Use a new locknut where the OEM procedure requires replacement.

Please confirm part number 4306520, the transmission tag, output configuration, and applicable Eaton torque procedure before ordering.
