Travel pedal stiff, unresponsive or the 320D creeping when no pedal input is given? A worn 369-8503 foot pedal valve loses its spool centreing accuracy, causing the travel motor to receive an unwanted pilot signal that results in unexpected machine movement. RITO supplies this precision foot pedal valve to restore clean, proportional travel speed control on your 320D or 323D.

In Stock369-8503 Travel Foot Pedal Valve for Caterpillar 320D, 323D, 325D, 329D and 336D excavators. Cross-references: 369-8502 and 270-5947. The 369-8503 converts foot-pedal angle into a proportional pilot pressure signal for the travel motor displacement control valve. Precision spool geometry, calibrated return springs and sealed pivot ensure the linear pressure ramp and reliable neutral return essential for safe slope travel.

Return spring pre-load and spool stroke calibrated to 320D-336D pilot circuit specification, delivering the correct pressure ramp for travel motor displacement control.
369-8503 cross-references to 369-8502 and 270-5947 across the 320D-336D model range, ensuring correct application regardless of the existing part number stamped on the old valve.
Sealed pivot pin and filtered inlet prevent pilot oil contamination from silt-locking the spool, which causes the machine to creep or the pedal to stick in a partial-on position.
Spool land geometry designed to achieve zero pilot pressure in the centred position, preventing the 320D from inching forward on level ground when the operator lifts their foot.
FAQ
Q: How do I diagnose a failing 369-8503 pedal valve on 320D?
A: The 320D moves slowly when no pedal input is given, travel speed is unequal left to right at the same pedal angle, pilot pressure reads erratic during pedal application, or the pedal has a stiff mid-stroke feel inconsistent with the other pedal.
Q: Is 369-8503 the same valve as 369-8502 and 270-5947?
A: They are cross-references covering the 320D-336D travel pedal valve application across model years. Confirm the correct cross-reference for your specific machine before ordering.
Q: What should I check if the 320D still creeps after fitting a new 369-8503?
A: Check the travel motor displacement valve for spool sticking, test the pilot circuit pressure at the travel motor control port in the neutral position, and inspect the pilot inline strainer for debris that may have contaminated the new valve.
Q: How to confirm 369-8503 fits my 320D or 323D?
A: Match the existing pedal valve part number 369-8503, 369-8502 or 270-5947 and confirm the machine is in the 320D-336D series. Provide machine serial number for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
