Excavator Hydraulic Part

FAQ


Q: What diagnostics indicate a transmission sleeve bearing has reached its wear limit?
A: Increased transmission oil temperature, fine bronze shavings found in the oil filter, a whining sound from the gearbox, and subtle shaft play indicate bearing surface wear.
 
Q: What technical requirements must be met during press-fit sleeve bearing installation?
A: Use a hydraulic press with a properly sized mandril to ensure the bushing is driven perfectly straight. Never hit the bearing directly, and ensure the oil lubrication port aligns with the housing oil passage.
 
Q: How do procurement managers verify the application scope of this sleeve bearing?
A: Confirm the OEM part number is 173-3428. It is a direct fit for transmission systems in 320D, 325D, 330D, and 336D excavators and D6G / D7G crawler tractors.
 
Q: How does this bearing maintain stability under extreme heavy-duty quarry workloads?
A: Utilizing a high-grade bimetallic alloy structure, it operates reliably at up to 130 degrees Celsius, resisting thermal deformation and fatiguing under high shock loads.
 
Q: Why should heavy machinery parts dealers partner with RITO for bushing lines?
A: We offer consistent dimensional accuracy across all manufacturing batches, allowing your dealership to provide dependable components that eliminate field failures and build customer trust.
 

Q: What quality options are available?

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