Description
When your dual power transmission won’t shift right or feels sluggish moving between ranges, the problem might be smaller than you think. This valve spring is one of those little parts that makes a big difference – it keeps your dual power valve operating smoothly and shifting when it should. Without proper spring pressure, your transmission can get stuck in one range or shift erratically, leaving you without the speed options you need for different field conditions.
What You’re Getting
- Precise spring pressure keeps your dual power valve functioning reliably
- Durable construction handles constant compression and release cycles
- Direct replacement part – no modifications needed for proper fit
- Maintains proper hydraulic pressure for smooth range shifting
Built for Real Farm Work
This spring works inside the dual power transmission valve on Ford New Holland tractors from the 10, 30, and 40 Series. These are the tractors handling everything from field cultivation and hay operations to loader work and transport duties. The dual power feature lets you shift on-the-go between working speeds and transport speeds – essential when you’re baling thick windrows or need to move quickly between fields.
Made to Last
Dual power springs live in a tough environment with constant hydraulic pressure, temperature changes, and thousands of compression cycles. This spring is built to handle that abuse while maintaining consistent pressure over years of operation. Quality materials and proper heat treating ensure it won’t lose its tension or break under stress.
Installation Notes
This spring installs inside the dual power valve assembly, so you’ll need to partially disassemble the valve to replace it. Make sure to relieve hydraulic pressure before starting work and keep everything clean during assembly. If you’re rebuilding the entire dual power system, consider replacing related seals and gaskets while you’ve got it apart.
