5. FAQ

Q: What road‑working construction machine does part number 707‑98‑25870 apply for cylinder overhaul jobs?
A: Part number 707‑98‑25870 cylinder seal kit is purpose‑built for motor grader ripper cylinder assembly maintenance and complete overhaul service.

Q: What sealing output can part number 707‑98‑25870 bring to ripper cylinder hydraulic circuit?
A: Part number 707‑98‑25870 cylinder seal kit preserves steady hydraulic pressure during ripper tooth piercing and lifting cycles, cuts down internal oil bypass under hard‑ground breaking load, and blocks crushed rock dust and sticky mud from entering cylinder chamber to protect piston and rod mating surfaces.

Q: What raw materials form this ripper cylinder seal kit?
A: Dynamic rod seals adopt high‑impact‑resistant PU polyurethane, static sealing O‑rings use heat‑resistant FKM fluoro‑rubber, and PTFE side‑force resistant backup ring absorbs offset thrust force and prevents seal extrusion damage under sharp pressure spikes.

Q: What color appearance do these sealing spare parts feature?
A: PU sealing elements are deep dark‑black, HNBR rubber fittings are glossy jet‑black, PTFE pressure‑resistant backup rings are light ivory‑white.

Q: Can this product prevent hydraulic oil leakage effectively?
A: The precise size design effectively reduces internal leakage and external oil seepage.

Q: What construction scenarios often require this arm cylinder seal kit for regular maintenance?
A: It is widely used for maintaining mini excavators working on villa foundation projects, landscape engineering, pipeline trenching and rural road reconstruction.
