Keep the front input shaft of your manual transmission spinning true with the Timken Manual Transmission Input Shaft Bearing NP007430, a tapered roller bearing cone that installs in the front position as a direct-fit replacement for the listed applications: the 1999 Ford F-250 Super Duty, F-350 Super Duty, F-450 Super Duty, and F-550 Super Duty [All] engines.
Tapered roller design: the cone (inner) member carries both radial and axial loads, helping locate and support the rotating input shaft.
Built for demanding duty: engineered to handle higher speeds, heavier loads, and longer service life in a compact package.
Timken engineering: from a recognized global leader in tapered roller bearings, backed by extensive technology and engineering support.
Replace in matched pairs: the inner cone and its outer cup should be replaced together to maximize reliability and life.
Worn tapered bearings can show up as noise, roughness, or play at the input shaft — signs this bearing may need replacing. Diagnose the cause before replacing. The listed applications use two per vehicle, so order the quantity your job requires and replace each cone with its mating cup.
Interchange: Manufacturer part number NP007430.
