When you’re dealing with hydraulic pump connections that don’t quite line up, or you need to convert between different drive configurations, this pump drive adapter gets your hydraulics back to working properly. It’s the kind of part that sits quietly doing its job until you need it—then it’s worth its weight in gold when your pump won’t connect or your hydraulic system isn’t getting the power it needs.
What You’re Getting
- 1-3/8 inch inside diameter female with 6-spline connection for secure, positive engagement
- 0.875 inch female round coupling with 3/16 x 3/32 inch keyway for keyed shaft connections
- 4-11/32 inch overall length provides the reach you need without excessive extension
- Precision-machined splines and keyway ensure proper fit and full power transfer
- Robust construction handles the constant torque and vibration of hydraulic pump operation
Built for Real Farm Work
This adapter bridges the gap between different hydraulic pump drive configurations you’ll find on tractors and implements. Whether you’re connecting a pump to an engine drive, adapting between different manufacturer’s systems, or replacing worn pump drive components, this piece handles the mechanical connection that keeps your hydraulics flowing. It’s designed for the kind of continuous operation that farm hydraulics demand.
Made to Last
Hydraulic pump drives take serious abuse—they’re spinning constantly under load, handling shock loads from implement operation, and dealing with the vibration that comes with engine-driven systems. This adapter is built from quality materials with proper heat treatment to resist wear and maintain tight tolerances season after season.
Good to Know
Clean both the splined and keyed connections thoroughly before installation—any debris or old grease prevents proper seating. The keyway should slide in smoothly without forcing, and the splined connection needs to engage fully for maximum power transfer. A light coating of grease on moving parts helps with assembly and long-term operation.
