4. FAQ

Q: Which engineering machinery does part number 707‑98‑11362 serve for repair and maintenance?
A: Part number 707‑98‑11362 cylinder seal kit is engineered for mini excavator boom cylinder assembly maintenance and full overhaul service.

Q: What sealing effect can part number 707‑98‑11362 achieve for the boom cylinder hydraulic system?
A: Part number 707‑98‑11362 cylinder seal kit maintains stable working pressure during boom lifting and lowering movements, reduces internal leakage under mixed load conditions, and blocks muddy slurry and fine grit from invading the cylinder interior and damaging the rod surface.

Q: What raw materials compose this boom cylinder seal kit?
A: Dynamic rod seals adopt high‑abrasion‑resistant PU polyurethane, static sealing O‑rings use heat‑resistant FKM fluoro‑rubber, and PTFE anti‑impact backup rings absorb side thrust and prevent seal extrusion under sudden pressure spikes.

Q: Where is this cylinder seal kit mounted on mini excavator?
A: These sealing assemblies are fitted inside cylinder barrel and cylinder head, surrounding piston and reciprocating bucket cylinder rod.

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.
