4. FAQ

Q: What heavy‑duty construction machine does part number 707‑98‑26520 fit for cylinder overhaul projects?
A: Part number 707‑98‑26520 cylinder seal kit is tailor‑made for wheel loader steering priority cylinder assembly maintenance and complete overhaul service.

Q: What sealing performance can part number 707‑98‑26520 bring to steering priority cylinder hydraulic circuit?
A: Part number 707‑98‑26520 cylinder seal kit stabilizes hydraulic pressure during priority steering response, reduces internal pressure loss when steering shares oil flow with other actuators, and blocks construction‑site sand and wet sludge from entering cylinder cavity to protect piston and rod matching surfaces.

Q: What raw materials make up this steering priority cylinder seal kit?
A: Dynamic rod seals adopt high‑tear‑resistance PU polyurethane, static sealing O‑rings use heat‑resistant FKM fluoro‑rubber, and PTFE anti‑deformation backup ring bears compound pressure load and prevents seal extrusion damage under frequent oil‑flow switching.

Q: What sealing parts are included inside this full repair kit?
A: It contains piston seals, rod seals, buffer rings, PTFE backup rings, dust wiper seals and various sizes of supporting O‑rings for cylinder reassembly.

Q: Where is this cylinder seal kit mounted on mini excavator?
A: These sealing assemblies are installed 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.
