Application and Service Notes

Confirm the transmission model, serial number, specification number, input-shaft length and spline, clutch-pull configuration, front bearing cover, bearing, seal, main drive gear, snap-ring arrangement, and existing shaft number before ordering. Do not select an input-shaft kit solely by transmission family or visual comparison.

Installation must follow the applicable Eaton service or overhaul manual for transmission removal, bearing-cover service, input-shaft replacement, seal installation, end play, bearing fit, snap-ring selection, torque, clutch alignment, and lubricant refill.

Please confirm K-4144, the transmission identification tag, input-shaft and main-drive-gear configuration, front bearing cover, and all kit contents before ordering.

Parts Verification and Ordering Notice

Please confirm the existing part number, transmission model and serial number, shaft dimensions and spline, bearing-cover design, specifications, kit contents, and application before ordering. Cross-reference numbers, parts catalogs, service manuals, repair manuals, PDF references, and application guides are reference material only and may contain errors, omissions, superseded information, or model-specific differences.
