Installation & Application Notes

Clean mating surfaces before fitting cab seals to prevent air and water ingress. Use correct adhesive for glass bonding — structural automotive adhesive, not silicone. Check wiring harness routing when replacing doors or panels.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a failing oil seal is usually a visible oil leak from the housing or shaft it seals. If ignored, the leak can worsen, leading to insufficient lubrication of the component, potential overheating, and contamination of the fluid. This can cause premature wear on bearings and gears, leading to significant component damage.

Installation Tip

Ensure the shaft and the seal bore are meticulously clean before installation, and lightly lubricate the seal's lip with appropriate grease. Avoid using excessive force or a screwdriver to press the seal, which can damage its sealing surface.

Service Note

Inspect the shaft for any nicks or wear that could damage the new seal; clean and lubricate the seal lip prior to installation.
