Frequently Asked Questions
Q: What equipment does the YL 2-730015200 brush spring fit?
A: The YL 2-730015200 is an OEM brush spring for Yale DC traction motors in MPB040E (B827) and MPW045E (B802) electric lift trucks. Verify your motor model designation before ordering to ensure proper fitment.
Q: What material is the YL 2-730015200 brush spring made from?
A: The YL 2-730015200 is constructed from high-carbon steel to ASTM A228 specifications with oil-tempered processing. This material provides consistent spring force and resistance to fatigue over extended service life.
Q: What is the wire diameter of the YL 2-730015200?
A: The YL 2-730015200 has a precision wire diameter of 0.055 inches. This dimension is engineered to fit standard motor brush holder channels. Do not substitute springs with different wire diameters.
Q: How long does the YL 2-730015200 last?
A: The YL 2-730015200 is rated for 500,000 compression cycles under normal operating conditions. Brush spring failure manifests as weak brush contact, reduced motor torque, or intermittent electrical connection. Replace if the spring no longer maintains consistent pressure on the brush.
Q: What happens if the YL 2-730015200 brush spring wears out?
A: A worn brush spring reduces contact pressure between the brush and commutator, causing poor electrical conduction, motor arcing, brush chatter, reduced traction power, and accelerated brush wear. Replace the spring immediately to prevent motor damage.
Q: Can the YL 2-730015200 be used in other motor applications?
A: The YL 2-730015200 is engineered specifically for Yale MPB040E (B827) and MPW045E (B802) motor assemblies. Use only for these OEM applications. Cross-compatibility with other motor types is not guaranteed.
