4. FAQ

Q: What materials compose this oil seal kit?
A: The sealing lip is XNBR carboxylated nitrile rubber for superior wear resistance, and outer shell is galvanized stamped‑steel equipped with high‑strength helical garter spring.

Q: What is the visual appearance of these sealing components?
A: The rubber lip is deep black with fine matte texture, and the metal shell has uniform reddish‑brown anti‑rust coating on outer surface.

Q: What lip design does this bulldozer seal kit adopt?
A: It adopts double‑lip integrated structure. The outer dust lip blocks soil dust, rock debris and muddy water splashes under rough earth‑moving working conditions.

Q: What temperature range can this seal work stably?
A: It maintains reliable sealing performance from ‑32℃ up to 107℃ under high‑vibration and heavily dusty construction environment.

Q: Where is this oil seal kit installed on the equipment?
A: It is assembled on final‑drive rotating shaft assemblies of bulldozer earth‑moving machinery.

Q: Does this repair kit contain all matching sealing accessories for one complete overhaul?
A: Yes, matched backup rings and assorted small auxiliary gaskets are included for full final‑drive system servicing.

Q: Can port maintenance technicians reuse these seal assemblies after disassembly?
A: Re‑installation is not recommended. Lip pre‑tightening stress will weaken after removal and may trigger slow lubricant leakage under humid port conditions.

Q: What practical working sign tells technicians to replace seals promptly?
A: Gradual grease seepage mixed with street sand and dust particles around brush‑drive housing indicates seal abrasion and gradual aging performance drop.
