Questions about this product?

Coupling only — not a hydraulic adapter kit or motor.

The Franklin XS439 SAE B hydraulic shaft coupling, part 305462041, is a service component for XS3x4-9 water truck pumps. It connects the pump shaft in the SAE B hydraulic-fit arrangement; it is not the SAE C coupling.

The B-fit configuration uses a 13-tooth involute SAE B spline with 16/32-inch spline pitch and a 30-degree pressure angle. Match the hydraulic motor interface before ordering. This listing is for the coupling only, not a complete adapter assembly; the motor mount, coupling set-screw pack and adapter plate are separate service components.

Match the SAE B drive interface

Feature Benefit
SAE B hydraulic fit Match the coupling to the B-fit drive arrangement rather than the C-fit version.
Coupling-only service part Replace the coupling without ordering a complete hydraulic adapter assembly.
