description

This drive gear is the core transmission component for engine pump assembly. It features precise 51-tooth involute profile, forged low alloy steel with carburized hardened tooth surface. It meshes with driven gear to transmit power to lube pump and maintain steady oil circulation. Designed for heavy-duty mining and construction equipment, it withstands cyclic meshing load, delivers smooth drive and stable oil supply, widely used for lube pump overhaul replacement.

Part number: 292-3512
Alternative name: Pump Drive Gear
Teeth: 14 teeth
Material: Low Alloy Steel
Process: Forging, rough machining, gear hobbing, carburizing hardening, finish grinding, crack inspection
Fit engine: CAT heavy-duty diesel engine
Fit machine: Large excavator, mining truck, track dozer, high-power generator set
Function: Transmit torque to drive lube pump and supply engine lubrication oil

Advantages

• Precise gear meshing and efficient power transmission.
• Capable of withstanding hydraulic pressure and mechanical forces.
• Suppresses noise and vibration during operation.
• Transmits power to the pump’s internal gears.
• Facilitates fluid displacement and the generation of hydraulic pressure.
1. Standard 14-tooth profile matches original driven gear for low meshing noise.
2. Carburized hardened teeth resist pitting and wear under long continuous load.
3. Forged steel substrate provides good toughness against tooth breakage under impact.
4. Precision bore and locating hole ensure good concentricity and low vibration at high speed.
5. Tight tolerance control keeps stable pump output and prevents insufficient lubrication.
6. Sold as single part, can replace gear separately without whole pump assembly.

FAQ 

Q1: Can 292-3512 interchange with gears of different tooth count?
A1: No. Tooth count defines gear ratio. It must pair with matched driven gear.
Q2: Can gear with slight pitting still be reused?
A2: Pitting spreads rapidly under heavy load and may cause tooth fracture. Replacement is recommended.
Q3: Should pump bushing be replaced together with gear?
A3: Replace bushing if worn with excessive clearance to extend gear service life.
Q4: How to store the gear?
A4: Coat teeth with anti-rust oil, pack separately and avoid tooth damage.
