Full Description
2-4-803 -- 1310 Round-Bore End Yoke, 1.375" Bore, 0.375" Keyway
Most driveshaft end yokes are splined -- they mate with a splined output shaft and are retained by a nut. The 2-4-803 is a round-bore yoke: the bore is smooth at 1.375 inches diameter, and the shaft is located by a 0.375-inch (EAR style) keyway cut into both the yoke bore and the shaft, plus a through-hole retaining bolt. Round-bore yokes appear on industrial equipment, custom driveshaft applications, and some agricultural machinery where the output shaft is a keyed round rather than a splined stub.
Before ordering: confirm your shaft OD is 1.375 inches and the keyway is 0.375 inches wide. Hub diameter is 2.000 inches; through-hole is 1.620 inches for the retaining fastener. CJ-to-end is 2.560 inches -- a compact yoke for tight clearance applications. 1310 ears accept a 1.062-inch cap U-joint.
