Travel control unresponsive or jerky on your 325D? A worn 158-8250 foot pedal valve fails to generate a stable pilot ramp, causing the travel motor to respond in steps rather than smoothly across the pedal arc. RITO supplies this precision pedal valve to restore feather-touch travel speed control on your 325D.

In Stock158-8250 Travel Foot Pedal Valve for Caterpillar 325D excavator. Designed specifically for the 325D travel pilot circuit, this valve provides a calibrated pressure ramp from zero to full travel pressure across the pedal range. Precision spool fit and factory-set spring pre-load maintain consistent pressure output across the service life of the valve.

Spring pre-load and spool stroke calibrated to 325D pilot circuit specifications, delivering the correct pressure range for travel motor displacement control on this model.
Spool land geometry designed to provide maximum operator sensitivity in the mid-pedal range where most grading and fine positioning work occurs.
Precision spool-to-bore clearance minimises null-position leakage, preventing the 325D from inching forward unintentionally on level ground.
Identical port layout and mounting pattern to OEM 158-8250 for direct swap without pilot line rerouting or bracket modifications.
FAQ
Q: How do I know if the 158-8250 pedal valve on my 325D needs replacing?
A: The 325D travels when no pedal input is given, travel speed is unequal left to right at the same pedal angle, or the pilot pressure gauge shows a stepped output instead of a smooth ramp during pedal application.
Q: Is 158-8250 the same part as 2705947?
A: No. 158-8250 is model-specific for the 325D while 2705947 covers other Cat models. Using the wrong part number may result in incorrect pressure calibration for the 325D circuit. Confirm the 158-8250 part number from your 325D parts manual.
Q: Can the 158-8250 pedal valve be rebuilt instead of replaced?
A: Spring replacement and seal kits are available for minor leakage repairs. However, a worn spool bore cannot be restored and requires a new valve to achieve the correct pressure ramp for the 325D travel circuit.
Q: How to confirm 158-8250 fits my 325D?
A: Match the existing part number 158-8250 on the old valve body, or provide the 325D serial number and machine configuration to our team.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
