The Spline Drive Adapter is a tool used for hydraulic pump and motor testing applications. It is used to securely mount hydraulic pumps and motors onto testing benches, ensuring stable alignment during operation. The adapter attaches directly to the pump and motor splines, allowing proper connection to mounting plates and stand assemblies. The adapter can also be used with an adapter and a size fifty-five drive shaft on a Hydraulic Test Center.Attributes:• Securely mounts pumps and motors for bench testing.• Attaches directly to pump and motor splines.• Enables a stable connection to mounting stands.Applications: The Spline Drive Adapter is used in hydraulic testing environments to mount hydraulic pumps and motors securely onto test benches for accurate and stable performance evaluation.
