5. FAQ
Q: What engineering machine does part number 707‑98‑13850 fit for maintenance work?
A: Part number 707‑98‑13850 cylinder seal kit is manufactured for mini excavator blade cylinder assembly repair and full overhaul service.
Q: What sealing effect can part number 707‑98‑13850 bring to blade cylinder hydraulic circuit?
A: Part number 707‑98‑13850 cylinder seal kit keeps stable hydraulic pressure during dozer blade lifting and ground leveling operations, reduces internal pressure loss under earth‑pushing load, and prevents site soil and fine dust from invading cylinder inner chamber to damage piston and rod surfaces.
Q: What raw materials make up this blade cylinder seal kit?
A: Dynamic rod seals adopt high‑wear‑resistant PU polyurethane, static O‑rings use aging‑resistant HNBR hydrogenated nitrile rubber, and PTFE anti‑fatigue backup rings bear side force and avoid seal squeeze damage under frequent pressure fluctuations.
Q: What color appearance do these sealing spare parts show?
A: PU sealing elements are deep glossy black, HNBR rubber accessories are dark matte black, PTFE anti‑fatigue backup rings are light milky‑white.
Q: What sealing components are packed inside this complete repair kit?
A: It includes piston seals, rod seals, shock buffer rings, PTFE backup rings, dust wiper seals and multiple groups of multi‑size O‑rings for cylinder reassembly.
Q: Where is this cylinder seal kit assembled on articulated dump truck?
A: These sealing components are fitted inside cylinder barrel and cylinder head, surrounding piston and reciprocating hoist cylinder rod.
Q: Can the sealing combination stop internal leakage and external oil seepage effectively?
A: Multi-stage sealing structure greatly reduces the risk of hydraulic oil leakage.
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.
