5. FAQ

Q: What construction machinery does part number 707‑98‑12320 apply for component overhaul work?
A: Part number 707‑98‑12320 cylinder seal kit is specially manufactured for wheel loader steering cylinder assembly maintenance and full overhaul.

Q: What sealing capability can part number 707‑98‑12320 deliver for the steering cylinder hydraulic circuit?
A: Part number 707‑98‑12320 cylinder seal kit holds stable hydraulic pressure during frequent wheel steering operations, lowers internal fluid bypass under bumpy driving vibration, and prevents road dust and fine sand from invading cylinder inner cavity and scratching rod surface.

Q: What raw materials make up this steering cylinder seal kit?
A: Dynamic reciprocating rod seals adopt wear‑resistant PU polyurethane, static sealing O‑rings use oil‑resistant NBR nitrile rubber, and PTFE shock‑resistant backup rings absorb lateral impact force and avoid seal extrusion under sudden pressure spikes.

Q: What color appearance do these sealing spare parts have?
A: PU sealing elements are deep glossy black, NBR rubber pieces are matte jet‑black, PTFE shock‑resistant backup rings are light ivory‑white.

Q: What sealing components are packed inside this full 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: 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.
