description

This planetary gear is made of low alloy carburized steel with hardened tooth surface. It is the core component of final drive planetary assembly. Pitting, broken teeth, scored end face and worn bore lead to travel noise, excessive clearance, power slip and weak traction. Heavy load easily causes tooth breakage and planetary set failure.

Part No.: 7G-2476

Installation Position: Final drive planetary carrier
Matching Parts: planetary needle bearing, thrust plate, sun gear, ring gear, gear oil selected as overhaul set on demand

Application Scenarios

Fit for CAT 834G,834H wheel dozers, 825/826 compactors, 24H,24M motor graders, 589 pipelayer, 770,772 mining trucks, D9R, D10N dozer. Suitable for mining and heavy earthmoving. Used to replace damaged gear during final drive overhaul and tooth failure repair.

FAQ 

Q: Can 7G-2476 interchange with 7G-3457?
A: No. 7G-2476 is 20T while 7G-3457 is 25T. Mismatched ratio destroys planetary set.

Q: Can gear with light surface pitting keep working?
A: Not recommended. Pitting spreads under load and may crack teeth and lock travel drive.

Q: What risk if only planetary gear is replaced without new needle bearing and thrust plate?
A: Worn old bearing and thrust plate create excessive clearance. New gear meshes off-center and breaks quickly.

Q: Only one gear damaged in planetary set, can I replace only this one?
A: Not recommended. Remaining gears are fatigued. Mismatched wear rate leads to early failure.
