D6D BOTTOM ROLLER DF PART NO.:9G8034
Product Overview
Part Number: 9G8034
Fit Machine: CAT D6D Medium Crawler Bulldozer
This track roller (bottom roller) is a heavy-duty aftermarket replacement undercarriage wear part designed for CAT D6D construction bulldozers. Forged from high-strength alloy steel and processed with full-surface deep carburizing quenching heat treatment, it is fitted with a triple-layer anti-mud leak-proof oil seal system. The roller carries the full weight of the bulldozer and supports smooth track chain movement in municipal road projects, farm grading sites and small stone quarry construction environments.
Core Advantages
Precision Machined Replacement Installation Dimensions
The roller width, shaft length and mounting hole sizes are precisely machined to fit CAT D6D bulldozers perfectly. Direct bolt-on installation is available without any cutting or modification work.
Deep Hardened Roller Surface
Deep carburizing quenching treatment provides ultra-high surface hardness and excellent anti-abrasion performance, effectively extending service life on rocky and muddy construction job sites.
Triple Multi-Layer Mud-Proof Oil Seal
High temperature and sediment resistant composite rubber seals prevent mud, water penetration and grease leakage, significantly cutting down maintenance frequency for daily bulldozer pushing work.
Reinforced Heavy-Duty Internal Bearing
Features strong load-bearing capacity and stable smooth rotation, preventing track shaking, jumping and chain derailment during medium-load operation.
Strict Factory Full Inspection
Each bottom roller undergoes hardness testing, hydraulic leak testing and dimensional calibration before packaging to ensure consistent and stable overall quality.
Compatible Equipment
This aftermarket replacement roller fits CAT D6D crawler bulldozer perfectly.
