The bull gear is a critical power-transmission component in the final drive, transferring torque from the drive train to the sprocket shaft and ultimately to the tracks. This is the 33-spline version correct for early 450 machines -- later Fits Case dozer models use a different spline count and are not compatible. Verify your machine is an early 450 with 33 splines before ordering.\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e  \u003cli\u003eSpline Count: 33 Splines\u003c\/li\u003e  \u003cli\u003eTooth Count: 76 Teeth\u003c\/li\u003e  \u003cli\u003eSpline Inside Diameter: 2-21\/32\"\u003c\/li\u003e  \u003cli\u003eApplication: Final Drive Assembly\u003c\/li\u003e  \u003cli\u003eMachine Needs: 2 per machine (one per side)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatible Models\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eFits Case (Fits Case IH) Crawler Dozers:\u003c\/strong\u003e Early 450 (33-spline final drive)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This 33-spline bull gear is specific to early 450 dozers.
