Selection guide

Selection Tips 1. Confirm dimension ID100mm, OD140mm, mounting thickness11mm, total height21mm, TB step‑metal‑shell structure and OEM number 31C89G‑04080. 2. Standard NBR version for normal rear‑axle gear‑oil environment; select FKM upgrade for high‑temperature heavy‑load working condition. 3. Inspect shaft and housing bore before installation; repair shaft wear, corrosion and burrs. Damaged mating surfaces will trigger premature oil‑seal leakage. Installation Steps Preparation Thoroughly clean axle housing bore and half‑shaft surface, remove old seal fragments, grease dirt and metal burrs. Pre‑lubrication Coat sealing lip and shaft surface with matched heavy‑duty differential gear‑oil. Dry installation is strictly forbidden; dry friction will burn sealing lip quickly. Orientation Confirmation Main sealing lip points toward gear‑oil cavity; outer dust lip faces outward. Wrong installation direction leads to oil leakage and lost mud‑proof protection. Vertical Press‑fit Use dedicated press‑sleeve tool to press TB oil‑seal evenly and vertically. Never strike rubber lip or metal shell directly, to avoid shell deformation and lip tearing. Seating Inspection Ensure full flat contact between seal shell and housing seating surface, no tilt or gap. Visual Check Examine sealing lip for invisible nicks and shell deformation; tiny hidden damage will cause seepage after commissioning. Rotation Test Manually rotate hub assembly to confirm smooth rotation without abnormal binding resistance.
