When fitting the 10-4-143, the mating shaft must be 1.125" diameter with a 0.250" keyway. The GAP-0.25 keyway designation indicates a standard gap-style key seat. The 2.25" hub diameter and 1.20" through-hole must be confirmed against the housing bore and retaining fastener dimensions. ISR retention requires the U-joint caps to have internal snap ring grooves seated inside the yoke ear bores — confirm U-joint style is ISR in the 1000 series.
The 1000 series is the lowest torque-rated SAE series available; confirm the application torque does not require a 1210 or higher series. The round bore with keyway configuration is used on light-duty machinery, agricultural equipment, and industrial shaft applications where keyed outputs are standard. Verify bore diameter is 1.125" and keyway width is 0.250" against the mating shaft before ordering the 10-4-143.
