5. FAQ

Q: What construction machine does part number 707‑98‑14740 apply for cylinder repair work?
A: Part number 707‑98‑14740 cylinder seal kit is specially manufactured for backhoe loader arm cylinder assembly maintenance and full overhaul service.

Q: What sealing capability can part number 707‑98‑14740 provide for arm cylinder hydraulic circuit?
A: Part number 707‑98‑14740 cylinder seal kit maintains stable hydraulic pressure during arm extending and retracting digging movements, reduces internal fluid loss under mixed digging load, and prevents muddy debris and construction dust from entering cylinder inner chamber to scratch piston and rod surfaces.

Q: What raw materials compose this arm cylinder seal kit?
A: Dynamic rod seals adopt high‑strength PU polyurethane, static sealing O‑rings use heat‑resistant FKM fluoro‑rubber, and PTFE impact‑resistant backup rings bear transverse force and avoid seal squeeze damage under frequent pressure fluctuations.

Q: What color appearance do these sealing spare parts present?
A: PU sealing elements are deep jet‑black, FKM rubber accessories are dark brown‑black, PTFE impact‑resistant backup rings are pale milky‑white.

Q: What sealing accessories are contained inside this complete repair kit?
A: It includes piston seals, rod seals, pressure buffer rings, PTFE backup rings, dust wiper seals and multiple groups of different‑size O‑rings for cylinder reassembly.

Q: What sealing accessories are packed inside this whole repair kit?
A: It includes piston seals, rod seals, buffer rings, PTFE backup rings, dust wiper seals and multiple specifications of matching 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: What sealing accessories are contained within this whole repair kit?
A: It includes piston seals, rod seals, pressure buffer rings, PTFE anti‑extrusion rings, dust wiper seals and multi‑size matched 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?
A: It is widely used for maintaining mini excavators working on villa foundation projects, landscape engineering, pipeline trenching and rural road reconstruction.
