RITO CASE CX800 Swing Reduction Gearbox Excavator Spare Parts Swing Reduction Gearbox Assembly

Rising oil temperature, metal particles in the swing housing oil or a machine that creeps and then stops are classic symptoms of a tired CASE CX800 Swing Reduction Gearbox. Once the bearing preload is lost the gear mesh runs out of alignment and wear accelerates quickly. RITO supplies this CASE CX800 Swing Reduction Gearbox as a complete unit for standard excavators, returning swing torque and swing speed to specification.

As a complete CASE CX800 Swing Reduction Gearbox, this assembly covers everything behind the hydraulic motor: ring gear, planet gears, carriers, bearings, seals and output shaft. Using one matched assembly avoids the mismatch that comes from mixing new gears with worn carriers, which is the usual reason a rebuilt unit fails again within a few hundred hours. It fits the standard mounting of standard excavators and is supplied ready to install.

Key Features & Advantages

Double-Lip Sealing

A double-lip output seal plus O-ring joints keep abrasive dust out of the oil, the main reason reduction units fail early on demolition and quarry work.

Bolt-On Fitment

Mounting pattern, output spline and overall envelope follow the original unit, so the assembly installs with the existing bolts, hoses and guards.

Hardened Internals

Gears and shafts are case hardened and ground, giving a tooth surface that resists pitting under the shock loads typical of excavator travel and swing duty.

Rigid Cast Housing

The ring gear and bearing bores sit in one casting, holding bore alignment under load so the gear mesh does not walk out of position.

FAQ

Q: What usually causes these reduction units to fail?
A: Contaminated oil and lost bearing preload. Once dust enters through a worn seal, the bearings loosen, the gear mesh misaligns and the unit starts to whine and overheat within a few hundred hours.

 

Q: Do I need to adjust backlash after fitting?
A: No. Backlash and bearing preload are set at assembly. Fit the unit, fill with the specified oil grade, and check for leaks after the first few hours of operation.

 

Q: Is this a complete assembly or just the gear set?
A: It is supplied as a complete reduction assembly - housing, ring gear, planet gears, carriers, bearings, seals and output shaft - so nothing has to be transferred from the old unit.

 

Q: How do I confirm this CASE CX800 unit fits my machine?
A: Compare the mounting bolt pattern, the output spline and the overall height against the unit on your machine, and check the model plate. If the numbers differ, send us a photo of the plate and we will confirm the correct variant.

 

Q: Which oil should I use after installation?
A: Use the grade listed in the machine service manual for the final drive or swing reduction. Overfilling causes heat; underfilling causes immediate bearing damage, so fill to the level plug.

 

Q: Can this unit be used as an upgrade on an older machine?
A: Where the mounting pattern and spline match, the later specification can be fitted to earlier machines. Confirm the interface dimensions with us before ordering.
