CAT 506-4204 is a Caterpillar drive axle hub flange, adapted for the drive axle ends of wheel loaders, excavators, and other equipment. It is used to secure the wheel hub to the brake disc, transmit torque, and position the bearings. The following is professional structured information.
Core Parameters (Professional Version)
Project Details
Basic Attributes
Model 506-4204, Quantity per unit: 1 piece/hub, Fits shaft diameter 110 mm, Matching bearing 567-7156, Bolt 6V-3762 (Grade 10.9), Weight 3.2 kg, Used for drive axle hub shaft end, requires interference fit with journal.
Key Dimensions
Inner diameter 110 mm (tolerance 0–+0.015 mm), Outer diameter 280 mm (tolerance 0–-0.02 mm), Thickness 32 mm (tolerance ±0.1 mm), Bolt hole distribution circle diameter 220 mm, Number of bolt holes 8 (diameter 18 mm, tolerance +0.05 mm), Locating stop diameter 150 mm (tolerance 0–+0.02 mm), Stop depth 5 mm (tolerance ±0.1 mm)
Material and Process
Body is 42CrMo Alloy steel, quenched and tempered (hardness HRC28–32), powder-coated for corrosion protection; bolt holes are roll-formed, thread specification M16×1.5 (compatible with 6V-3762 bolts), locating stop surface roughness Ra≤1.6 μm
Performance Parameters: Rated torque 1200 N・m, maximum load capacity 80 kN, operating temperature -40℃ to +120℃, bolt preload torque 280 N・m, compatible bearing clearance 0.05–0.12 mm
Compatible Models: Cat 950GC/962GC loaders, 320GC/323GC excavators, M318F wheeled excavators, matching drive axle model 8J-3200, hub assembly 114-9269
Installation and Maintenance Points: Clean the flange and journal/hub contact surfaces before installation. The journal needs to be ground to φ110h6 (tolerance). For flanges with a diameter of 0–0.015 mm, heat-fit (80℃ for 30 minutes) and press-fit, with a pressing force ≤80 kN, ensuring end face fit (gap ≤0.03 mm).
Bolt Installation: Use 6V-3762 bolts (grade 10.9), apply thread-locking adhesive (Loctite 243), and tighten in three diagonal stages to a final torque of 280 N·m. After installation, check that the flange runout is ≤0.05 mm.
Maintenance Cycle: Check bolt torque every 1000 hours (allowable deviation ±5%), and check flange wear every 2000 hours (replace when wear >0.5 mm). Avoid overload and impact loads.
Troubleshooting: If abnormal noise/vibration occurs in the hub, first check for flange deformation, loose bolts, and worn locating stops. If necessary, disassemble and replace and repair the journal/hub.
