Swing speed reduced to a crawl or swing motor leaking on your Caterpillar excavator? A worn 267-6845 swing motor assembly loses motor efficiency while the gearbox drops reduction accuracy, combining to rob your machine of the torque needed for swift cab rotation. RITO's complete swing motor assembly restores rated swing speed and clean, dry motor operation.

In Stock267-6845 Swing Motor Assembly for Caterpillar excavator. Integrates the axial piston hydraulic swing motor with the multi-stage planetary swing reduction gearbox and the swing brake valve. The motor converts hydraulic flow to rotary torque; the gearbox multiplies that torque at the swing pinion; the brake valve prevents uncontrolled coasting during deceleration. All three functions are restored together in one assembly.

One complete assembly replacement eliminates the compatibility risk between separately-sourced motor and gearbox components, ensuring port alignment and oil circuit integrity from installation.
Precision cylinder block, piston shoes and valve plate in the motor section maintain rated displacement and high volumetric efficiency across the swing duty cycle.
Multi-stage planetary reducer provides the reduction ratio needed for Cat swing speed with controlled backlash at the pinion output for smooth reversals.
Factory-calibrated swing brake valve provides controlled deceleration torque, preventing cab overswing and protecting the slew ring from reversal shock.
FAQ
Q: What are the symptoms of a failing 267-6845 swing motor assembly?
A: Swing speed progressively drops, cab overswings and is hard to control during deceleration, oil leaks from motor case or gearbox seals, swing motor gets excessively hot, and case-drain flow exceeds OEM spec on a flow meter test.
Q: How do I check whether the 267-6845 motor or gearbox section has failed before replacing the full assembly?
A: Measure motor case-drain flow at rated swing speed. Flow above 10-12 L/min confirms motor rotating group wear. If drain flow is within spec but swing speed is low and gearbox oil has metal particles, the gearbox section is the primary failure.
Q: Does the 267-6845 swing motor assembly include the swing brake valve?
A: Yes, the complete assembly as supplied by RITO includes the swing brake valve block as an integral part. Confirm the assembly specification matches your Cat model configuration before ordering.
Q: How to confirm 267-6845 fits my Cat excavator?
A: Match hydraulic port sizes, motor case flange bolt pattern and swing gearbox housing mounting dimensions. Provide the machine model and 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.
