Slewing rough or upper structure rocking on your 315DL? A worn 267-6831 slew ring develops uneven ball groove wear that creates a dead spot in the swing arc, jerking the cab unpredictably during controlled rotation. RITO's heavy-duty slewing ring eliminates that dead spot and restores smooth, 360-degree upper structure rotation.

In Stock267-6831 Hydraulic Slew Ring for Caterpillar 315DL excavator. The slew ring is the sole mechanical connection between the upper and lower structures, carrying the entire upper mass through its ball groove while transmitting swing torque through its internal gear teeth. Critical dimensions are the ball groove hardness, gear tooth quality and bolt circle precision for alignment.

Ball groove surface hardened to HRC 55-60 by induction process to maintain correct ball-groove contact geometry under the static dead weight of the 315DL upper structure.
Internal swing gear teeth hobbed to DIN 8 or better, providing low-noise, backlash-controlled engagement with the swing motor pinion across the full swing circle.
Dual-lip seals on inner and outer race retain lithium-complex grease while blocking abrasive fines from entering the ball groove and accelerating wear.
Inner and outer ring bolt-circle diameters machined to 315DL OEM tolerance for correct swing pinion centreline alignment after installation.
FAQ
Q: How to measure if the 267-6831 slew ring on my 315DL needs replacing?
A: Use a dial gauge on the counterweight or boom foot pin: vertical play above 2 mm indicates ball groove wear. Rotate slowly and feel for periodic resistance or roughness indicating a worn or contaminated section.
Q: How long does 267-6831 slew ring installation take on a 315DL?
A: A skilled team with correct lifting equipment typically completes slew ring replacement in 8-12 hours. Key steps are upper structure support, old ring removal, seating surface cleaning, correct bolt torque sequence and swing pinion backlash adjustment.
Q: What grease interval should I follow after fitting a new 267-6831?
A: Grease every 50 hours minimum during the first 500 hours after installation, then follow the Caterpillar 315DL maintenance schedule. Rotate the upper structure while greasing to distribute grease to all balls.
Q: How to confirm 267-6831 is the correct slew ring for my 315DL?
A: Match outer diameter, inner bore, bolt count, bolt-circle diameter and internal gear tooth count. Provide the 315DL serial number to our team for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
