10-0443 – End Yoke – 1000 Series – 1.62″ Hub Dia – 2.500″ Cj To End

Matching a PTO end yoke to the output shaft requires three confirmed dimensions: bore diameter, hub outer diameter, and keyway specification. The 10-0443 carries a OEM-specified" bore, a 1.62" hub diameter, and a standard keyway -- the combination that defines correct fit on 1000 series PTO shafts used in agricultural, forestry, and construction equipment.

Dimensional Reference

PTO Yoke Selection Fundamentals

A PTO end yoke must be sized for both the driveshaft U-joint series and the driven shaft geometry. The U-joint series -- in this case, 1000 -- determines the bearing cup cap diameter and torque rating. The bore, hub, and keyway dimensions determine whether the yoke will mount correctly on the PTO output shaft without excessive runout or fretting at the key-to-keyway interface.

The listed-inch bore of the 10-0443 accommodates standard 1000 output shafts. The included keyway transmits torque mechanically, but the retaining fastener -- typically a set screw or through-bolt specified in the equipment manual -- provides the axial retention that prevents the yoke from walking off the shaft under load reversals.

Installation and Torque Recommendations

• Clean the mating shaft and bore bore of any burrs or corrosion before assembly
• Verify keyway alignment is correct before pressing the yoke onto the shaft
• Apply Loctite 243 (medium-strength thread locker) to set screws where specified
• Torque the retaining hardware to specification -- PTO yokes that work loose under load cause rapid keyway and bore damage that requires shaft rework
• After installation, rotate the assembly by hand to verify zero runout before connecting the driveshaft
