Heavy truck differential oil seal size 82*108*16 suitable for Fuwa 470 Meritor axle

1. Master and identify the basic knowledge of fake and inferior products, and choose high-quality and standard oil seals.
2. During installation, if the outer surface roughness of the shaft diameter is low or there are defects such as rust spots, rust, burrs, etc., use a fine emery cloth or oil stone to smooth it; apply clean oil or grease on the oil seal lip or the corresponding position of the shaft diameter. Apply sealant to the outer ring of the oil seal, wrap the keyway on the shaft with hard paper to avoid scratching the lip of the oil seal, and use a special tool to rotate the oil seal inward and press it in. Do not smash hard to prevent the oil seal from being deformed. Or crush the spring and fail; if the lip is flanged, the spring falls off and the oil seal is skewed, it must be removed and re-installed. It should be noted that when the shaft diameter is not worn and the oil seal spring has sufficient elasticity, do not tighten the inner spring [4] without authorization.
3. Oil seals used in machinery are generally subject to harsh working conditions, large environmental temperature differences, a lot of dust, and frequent vibrations of machines and tools, when the stress conditions of the parts are constantly changing, they should be inspected, maintained and maintained frequently.
