7N3536 Gear (80 Teeth) — Cat 3306

This is an 80-tooth gear, a fundamental component in mechanical power transmission systems, designed to mesh with other gears to transfer rotational motion and torque. Manufactured to meet stringent quality standards, it provides precise engagement and durability, unlike a worn gear with damaged teeth that can cause noise and power loss. Operators may hear grinding noises from the transmission or drivetrain, experience difficulty shifting gears, or notice a loss of power transfer when this gear is damaged.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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 noticeable symptom of a damaged 80-tooth gear is often an increase in operational noise, such as grinding or whining sounds. If the damage progresses, it can lead to intermittent engagement issues or a complete loss of power transfer. Continued operation with a worn gear risks further damage to adjacent gears and bearings, potentially causing a more extensive and costly drivetrain failure.

Installation Tip

Ensure the gear teeth are properly lubricated with the correct type of gear oil before installation to prevent initial wear. Avoid forcing the gear onto its shaft; it should slide into place with minimal resistance if aligned correctly.

Service Note

Always inspect the mating gear and bearings for wear or damage when replacing a gear.
