A malfunctioning regulator is often the result of contaminated oil. Ensure these parts are also serviced:

Q&A Section

Q1: My EC290B is "stalling" the engine when I dig hard. Is this the regulator?

A: Yes, that is a classic symptom. If the 14533619 regulator fails to "destroke" the pump (reduce flow) as pressure increases, the hydraulic load will exceed the engine's horsepower, causing it to bog down or stall.

Q2: Does this regulator fit both the front and rear pumps?

A: Most EC290B tandem pumps use two regulators. While they are often identical in part number (14533619), they are mirrored in their mounting. Ensure you are identifying the Front or Rear unit based on your pump's configuration.

Q3: Can I clean the regulator instead of replacing it?

A: If the issue is a stuck internal spool due to debris, cleaning may help. However, if the internal bores are worn or the springs have lost their tension, a full replacement of the 14533619 is necessary to restore factory performance.
