Frequently Asked Questions
Q: What are the critical dimensions of the CT 8K1253 ball joint?
A: The CT 8K1253 ball joint features a metric rod length of 17.5 mm, body pivot length of 31 mm, and stud pivot length of 28.4 mm. The threading follows UNF specification for compatibility with Caterpillar electric lift truck assemblies. Measure these dimensions against your assembly before ordering to ensure correct fitment.
Q: What equipment uses the CT 8K1253 ball joint?
A: The CT 8K1253 is designed specifically for Caterpillar electric lift truck assemblies. It serves in steering linkage, hydraulic cylinder rod end, or mast tilt mechanisms depending on the specific lift truck model. Verify your equipment is a Caterpillar electric model before ordering this part.
Q: What does UNF threading mean for this ball joint?
A: UNF stands for Unified National Fine threading, which is a standard metric-compatible thread specification. This means the stud and rod threads are fine-pitch UNF, requiring UNF-threaded sockets or fasteners for assembly. Do not attempt to use SAE or other thread types, as this will cause cross-threading and damage.
