RITO 223-6546 2236546 Excavator BOLT Hex Head Bolt Excavator 320D 320DL 330D Mounting Bolt for CAT Excavator Parts

Loose or sheared mounting bolts lead to severe component misalignment and expensive structural damage. Standard fasteners often fail under the intense vibration of CAT 320D/330D operations. A snapped 223-6546 can halt your entire mining project, turning a minor part into a major liability.

FAQ


Q: How do I know if the 223-6546 bolts need immediate replacement?
A: Inspect for visible thread stretching, necking, or rust bleeding around the bolt head. Any signs of loosening on the CAT 320D mounting brackets suggest the bolts have reached their fatigue limit.
 
Q: What are the torque requirements for installing the 223-6546 on a 330D?
A: Always refer to the CAT service manual for specific dry vs. lubricated torque specs. Use a calibrated torque wrench to ensure the bolt reaches its designed clamping force without overstressing.
 
Q: Is the 223-6546 suitable for both engine and hydraulic system mounting?
A: Yes, this high-strength hex bolt is versatile and used across various mounting points in CAT 320D and 320DL series, making it a vital stock item for mixed fleet repairs.
 
Q: Does this bolt maintain its clamping force in sub-zero mining climates?
A: Absolutely. The alloy steel used in the 223-6546 is tested to remain ductile and strong from -50°C, preventing brittle fractures in extreme cold-weather excavation.
 
Q: Can I reuse the 223-6546 bolts after a major component overhaul?
A: For critical load-bearing mounts, we recommend replacing them with new 223-6546 bolts to ensure maximum safety, as used fasteners often suffer from invisible micro-cracks or thread deformation.
 

Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
