Full Description
2-4-803 End Yoke 1310 Series Round Bore 1.375 Bore 0.375 Keyway 2.000 Hub
The 2-4-803 is a 1310 series end yoke with a round bore configuration. The bore diameter is 1.375" with a 0.375" keyway (EAR-0.38 style). The hub diameter is 2.000", the CJ to end dimension is 2.560", and the through-hole is 1.62". This yoke is designed for shaft-and-key installations rather than splined bores — the keyway locks rotational position between the yoke and the mating shaft.
Specifications
- Part Number: 2-4-803
- Series: 1310
- Bore Type: Round
- Bore Diameter: 1.375"
- Keyway: EAR-0.38 (0.375")
- Hub Diameter: 2.000"
- CJ to End: 2.560"
- Through Hole: 1.62"
When fitting the 2-4-803, the mating shaft must be 1.375" diameter with a matching 0.375" keyway machined at the appropriate position. The EAR-0.38 keyway style indicates the keyway is cut at the ear (end) of the bore. The 2.000" hub diameter and 1.62" through-hole determine clearance with any retaining collar or end fastener. The 2.560" CJ-to-end is compact — confirm this fits the installation geometry.
The 2-4-803 round bore configuration is used where a splined transmission or axle output is not present — common on PTOs, industrial equipment, and some aftermarket applications using keyed shafts. Confirm the shaft OD is exactly 1.375" and the keyway width is 0.375" before pressing or sliding the 2-4-803 onto the shaft. The 1310 series U-joint requirement applies at the mating end of this yoke.
