4I8135 Mirror — Cat 307 307B

This is a replacement mirror designed for specific CAT excavator models, providing the operator with essential visibility to the rear and sides of the machine. Manufactured to meet rigorous standards, it offers a clear and durable reflection, unlike a cracked or faded original mirror. Operators will notice a reduced field of vision or distorted reflections if this mirror is damaged or degraded.

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

A damaged mirror may present as cracks, fading, or a distorted reflection, immediately impairing the operator's view. Continued use with a compromised mirror increases the risk of collision or damage to surrounding objects. Failure to replace a broken mirror can lead to accidents and costly repairs.

Installation Tip

Clean the mounting surface thoroughly to ensure proper adhesion or secure fastening of the new mirror. Be careful not to apply excessive force when adjusting the mirror, as the mounting mechanism can be delicate.

Service Note

Inspect the mirror mounting bracket and surrounding cab structure for any signs of damage or corrosion during replacement.
