5. FAQ
Q: What construction machine does part number 707‑98‑13970 match for repair work?
A: Part number 707‑98‑13970 cylinder seal kit is specially manufactured for mini excavator arm cylinder assembly maintenance and full overhaul service.
Q: What sealing performance can part number 707‑98‑13970 bring to the arm cylinder hydraulic circuit?
A: Part number 707‑98‑13970 cylinder seal kit keeps stable hydraulic pressure during arm extending and retracting operations, reduces internal pressure loss under digging load, and prevents site dirt and fine gravel from entering cylinder inner chamber to scratch piston and rod surfaces.
Q: What raw materials are used for this arm cylinder seal kit?
A: Dynamic rod seals adopt wear‑resistant PU polyurethane, static sealing O‑rings use oil‑resistant NBR nitrile rubber, and PTFE anti‑deformation backup rings bear side load and avoid seal squeeze damage under frequent pressure changes.
Q: What color appearance do these sealing spare parts have?
A: PU sealing elements are deep glossy black, NBR rubber fittings are matte jet‑black, PTFE anti‑deformation backup rings are light milky‑white.
Q: What sealing parts are contained in this whole repair kit?
A: It includes piston seals, rod seals, buffer rings, PTFE backup rings, dust wiper seals and multiple sizes 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: 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.
