RITO 312 Travel Motor Assembly 311 313 314 312B Final Drive Motor 312 Excavator Track Drive Motor Final Drive Assy Unit

Imagine your CAT 312 maneuvering with a heavy payload near a steep embankment when one track suddenly loses power, causing the machine to pitch violently. When internal piston wear strips away the hydraulic pressure inside your original travel drive unit, execution speed plummets and straight-line steering becomes an impossible battle. Ignoring the continuous clicking or popping sounds from your undercarriage risks a catastrophic planetary gear lockup, leaving your 12-ton excavator stranded mid-shift and halting your entire earthmoving schedule.

Excavator Hydraulic Part

FAQ


Q: What primary operational failures confirm that a CAT 312B travel device requires complete replacement?
A: Watch for a complete loss of climbing power on steep slopes, severe tracking deviation while trying to travel straight, or visible gear oil leaking onto your track pads from behind the main sprocket wheel.
 
Q: What are the strict initial filling rules for setting up this reduction gearbox?
A: Rotate the final drive hub housing until the oil fill plug is level with the centerline. Add high-quality extreme-pressure gear oil until it reaches the overflow line, and perform a complete fluid swap after the initial fifty break-in working hours.
 
Q: How do procurement managers ensure a hassle-free mechanical fit across different production variants?
A: Always count the outer mounting holes on your track frame pocket and the inner bolt holes on your drive sprocket rim. Sharing these counts along with your model serial number prevents fitting errors across different production years.
 
Q: How does this final drive motor manage high-speed tracking across large construction sites?
A: It features an automatic two-speed swashplate displacement system that responds smoothly to changes in pilot pressure, adjusting tracking speed and torque on the fly to prevent internal hydraulic heat spikes during long travel legs.
 
Q: What quality options are available?

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