New CAT 2384462 Hydraulic Cylinder Seal Kit Caterpillar Aftermarket for Caterpillar 140H, 140K, 12H, 12K

The 2384462 hydraulic cylinder seal kit contains a set of seals designed to prevent fluid leakage inside hydraulic cylinders. These seals help maintain proper pressure, improve cylinder performance, and reduce wear on internal components.

Here’s a general guide for proper installation:

1. Turn off the machine and safely relieve all hydraulic system pressure.
2. Remove the hydraulic cylinder from the machine following your service manual instructions.
3. Disassemble the cylinder, taking note of seal locations and orientation.
4. Remove old seals and thoroughly clean all internal surfaces and grooves.
5. Install the new seals included in the 2384462 kit, ensuring correct orientation and proper seating in grooves.
6. Reassemble the cylinder, reinstall it on the machine, reconnect hydraulic lines, and refill fluid if needed.
7. Test the system to confirm proper sealing and cylinder operation.

The 2384462 seal kit is designed for use in hydraulic cylinders on machines such as 140H, 140K, 12H, and 12K graders where this part number is specified. Compatibility depends on your machine’s model and cylinder design, so verify fitment using your equipment’s service documentation before ordering. Please reach out to Propel Parts for help verifying fitment.

Yes, the 2384462 hydraulic cylinder seal kit is engineered to meet or exceed OEM specifications for sealing performance and durability. When servicing hydraulic cylinders, choose genuine or high-quality aftermarket parts that meet or exceed OEM expectations to help ensure reliable sealing and long service life.

Hydraulic seals should be checked during routine maintenance or whenever a cylinder is disassembled. Signs of leakage, decreased cylinder performance, or contamination in the fluid indicate it’s time for seal replacement. Regular inspection helps catch issues early and prevent further damage.

Typical indicators include:

1. Hydraulic fluid leaks around cylinder rods or housings
2. Reduced lifting or pushing performance
3. Jerky or inconsistent cylinder movement
4. Visible wear or damage on old seals

A quality seal kit helps maintain proper hydraulic pressure and prevents fluid loss, which supports smooth and efficient cylinder operation. Using genuine or high-quality aftermarket parts that meet or exceed OEM expectations helps reduce the risk of seal failure, improves reliability, and contributes to longer equipment service life.
