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 initial symptom of failing seals in a kit is often noticeable fluid leakage from the component's seals or external connections. If left unaddressed, this leakage can lead to a gradual loss of system pressure and reduced operational efficiency. Prolonged operation with leaking seals can cause damage to the component and surrounding parts due to insufficient lubrication or hydraulic force.

Installation Tip

Carefully clean all sealing surfaces and grooves before installing new seals to prevent contamination or damage. Ensure each seal is oriented correctly according to the component's service manual to guarantee proper sealing.

Service Note

Inspect the component's piston, rod, and bore for any scoring or wear that could compromise the new seals' performance.
