When the travel drive on a standard excavator loses power, runs hot or starts to slip, the R450 Travel Motor is the first place to look. Internal wear between the planet carriers and the ring gear turns motor torque into heat instead of motion. RITO offers the R450 Travel Motor complete with the gear set and bearings already shimmed, which restores tractive effort and travel speed and removes the guesswork of a field rebuild.

In StockThis R450 Travel Motor is built as a direct replacement for the original travel reduction unit on standard machines. The gear set is machined from hardened alloy steel and lapped in matched sets, the bearings are preloaded in the factory, and the sealing arrangement uses a double-lip shaft seal to keep dust out of the oil. The result is a unit that installs on the original bolt pattern and returns tractive effort and travel speed to the level the machine had when new.

 | Tested Before Packing Each unit is checked for backlash, turning torque and seal integrity, then packed in a reinforced case to survive international freight. |
 | Complete Assembly Ring gear, planets, carriers, bearings, seals and output shaft arrive as one unit, so nothing is reused from a worn original. |
 | Matched Gear Set Ring gear and planet gears are lapped as a matched set, so tooth contact is full width from the first hour and the unit stays quiet under load. |
 | Factory Preload Bearings are shimmed and preloaded on the assembly line, which removes the end float that causes noise and premature wear in field rebuilds. |
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 R450 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.
