Good To Know
Q: Is this speed sensor a genuine Caterpillar part? A: No, this is an aftermarket replacement component built for Caterpillar models, not an OEM part. It references OEM numbers for cross-reference purposes.
Q: Can I install this sensor without special tools? A: In most cases, yes, if you have basic hand tools and access to the sensor location. However, always confirm the sensor fits your specific serial number range before installation.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
