Product Overview
Part Number: 3P1039
Fit Machine: CAT D7G Medium Crawler Bulldozer
This heavy-duty aftermarket replacement sprocket segment (track segment) is designed for CAT D7G construction bulldozers. Manufactured from high-strength alloy steel with full-tooth carburizing deep quenching heat treatment, it meshes smoothly with matching track chains and delivers steady driving power for municipal road construction, stone quarrying and general earthmoving projects.
Core Advantages
Precision Machined Replacement Dimensions
The tooth profile, mounting hole spacing and overall outer size are precisely processed to fit CAT D7G bulldozer perfectly. It allows direct bolt-on installation without any cutting, welding or modification.
Deep Hardened Drive Teeth
The gear teeth surface reaches ultra-high hardness with superior wear resistance, greatly extending service lifespan on rocky and muddy construction job sites.
High Toughness Steel Body
Solid integrated steel structure effectively resists cracking and permanent deformation under long-duration medium-load pushing cycles.
Precision CNC Machining Tooth Profile
Finely calibrated tooth shape ensures seamless meshing with track links, lowers track abrasion, and efficiently avoids track jumping and derailment.
Strict Pre-Shipment Full Inspection
Each segment undergoes mandatory hardness testing and dimensional calibration before packaging to maintain consistent stable quality across all batches.
Compatible Machine
