Q&A

-
Q1: What are the main signs that a hydraulic cylinder needs a new 42N-6C-13330 seal kit?
-
A: Key performance warning signs include a layer of hydraulic oil coating the chrome cylinder rod, an uncharacteristic collection of grime at the edge of the cylinder gland nut, or internal cylinder fluid bypassing (where the bucket or boom drifts out of its set position while the joystick controllers are centered).
Q2: Can I use this kit to reseal a scarred or dented cylinder rod?
-
A: No. If the chrome plating on the cylinder rod is deeply scratched, dented, or showing signs of rust pitting, installing a new seal kit will only offer a temporary fix. The jagged edges of the damaged chrome will tear the lips of the new polyurethane seals within the first few hours of cycling. Ensure the metal surfaces are micro-polished and straight before reassembly.
Q3: Is any specialized equipment required to install the internal U-cup seals?
-
A: While the seals can be carefully installed by hand or with standard pick sets, using a dedicated hydraulic seal installation tool (a "twister" tool) is highly recommended. This tool allows you to safely fold the rigid polyurethane U-cups into a kidney shape, making them easy to slide into the internal gland grooves without puncturing or nicking the critical sealing edge.
