How to install an SKF dual-lip oil seal with a metal case?
To install an SKF dual-lip oil seal, ensure the bore is smooth and clean. Use a seal driver or press to apply even force on the metal case outer diameter, never on the sealing lips. Lubricate the shaft and seal lips before installation. Avoid cocking the seal; press it squarely to the correct depth.
