5. FAQ
Q: What type of construction machine does part number 707‑98‑13990 apply for repairing work?
A: Part number 707‑98‑13990 cylinder seal kit is specially produced for mini excavator boom cylinder assembly maintenance and full overhaul service.
Q: What sealing output can part number 707‑98‑13990 offer for boom cylinder hydraulic system?
A: Part number 707‑98‑13990 cylinder seal kit sustains steady hydraulic pressure during boom lifting and lowering actions, decreases internal pressure loss under uneven digging load, and blocks fine rock dust and muddy splashes from entering cylinder interior to harm precision contact surfaces.
Q: What raw materials constitute this boom cylinder seal kit?
A: Dynamic reciprocating rod seals adopt high‑strength PU polyurethane, static sealing O‑rings use heat‑resistant FKM fluoro‑rubber, and PTFE pressure‑resistant backup rings undertake side thrust and prevent seal extrusion under sudden pressure surges.
Q: What color features do these sealing spare parts display?
A: PU sealing elements are deep matte black, FKM rubber accessories are dark brown‑black, PTFE pressure‑resistant backup rings are pale ivory‑white.
Q: What sealing accessories are contained within this whole repair kit?
A: It includes piston seals, rod seals, shock buffer rings, PTFE backup rings, dust wiper seals and assorted multi‑dimension O‑rings for cylinder reassembly.
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?
