Description
When your David Brown tractor starts losing hydraulic power or the pump begins making grinding noises, a worn pump coupling is often the culprit hiding behind the trouble. This little but critical part connects your engine to the hydraulic pump, transferring power to run your loader, three-point hitch, and remote hydraulics. Without it working properly, you’ll find yourself stuck with sluggish hydraulic response or complete system failure right when you need it most.
What You’re Getting
- Precision-machined coupling that ensures smooth power transfer from engine to pump
- Durable construction built to handle the constant torque and stress of farm work
- Direct replacement part that fits perfectly without modifications or special tools
- Quality materials engineered to prevent premature wear and extend pump life
Built for Real Farm Work
This coupling fits David Brown 990, 990 Selectamatic, 1200, 1210, and 1212 tractors – machines you’ll find doing everything from hay work and tillage to loader operations and general farm tasks. These are the dependable tractors that keep working season after season, powering implements that need reliable hydraulic pressure to get the job done.
Made to Last
Your hydraulic pump coupling spins constantly when the engine runs, transferring significant torque under all operating conditions. This replacement uses quality materials and precision manufacturing to handle whatever you throw at it while maintaining proper alignment between engine and pump components.
Good to Know
Installation is straightforward for anyone comfortable working on tractor hydraulics, though you’ll want to properly support the hydraulic pump during the job. It’s smart to inspect related components like the pump drive hub when replacing the coupling, since worn parts can cause premature failure of the new coupling.
