Specs At A Glance

Good To Know

Q: Is this sensor a direct replacement for the original part? A: Yes, it carries the OEM cross-reference number 221-8859 and is designed to match the original specifications for the listed CAT models, but always verify serial number compatibility.

Q: Can I install this sensor myself? A: Installation typically requires basic mechanical skills, but because it involves hydraulic systems, ensure the machine is depressurized and follow your service manual for safety.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
