Product Overview
Product Overview for 123-6826 Final Drive Gearbox
123-6826 planetary final drive is a 3-stage drum travel reducer exclusively for CAT CS533C, CS563C, CS583C soil compactors, full OEM interchange replacement for CAT compaction equipment. Equipped with torque arm side mount flange, matched interface for 110-9506 MS18 hydraulic motor and double cone floating oil seal.
Carburized hard-tooth planetary gears and thick QT700 cast housing generate powerful low-speed torque for soil compaction, steep slope climbing and heavy vibration rolling, supporting plug-and-play direct replacement with no machine modification.
Rated working pressure 240 bar, peak pressure up to 280 bar, stable output under long continuous compaction loads. Shockproof rigid structure adapts to muddy, dusty road construction job sites.
Reinforced gear assembly and heavy-duty sealing perfectly mate with original CAT radial piston hydraulic motors without extra adapters, a durable, economical wheel drive gearbox for CAT single drum compactors.
Core Advantages
123-6826 is a 3-stage planetary final drive gearbox, fully OEM interchange replacement for CAT CS533C, CS563C, CS583C single drum soil compactors. Fitted with carburized hard-tooth planetary gears and heavy-duty composite roller bearings, this reducer outputs consistent low-speed high torque to handle heavy soil compaction and steep slope climbing loads.
It perfectly mates with original 110-9506 MS18 radial piston hydraulic motors without extra transition adapters, widely applicable to municipal, highway and infrastructure compaction projects. Thick QT700 high-strength ductile iron housing features a compact torque arm side-mount layout to fit standard compactor drum hub installation space. 1:1 identical OEM mounting flange, bolt holes and involute output splines enable plug-and-play swap, greatly shortening equipment maintenance downtime.
This heavy-duty high-torque drum drive unit operates at 240 bar rated working pressure and 280 bar peak pressure, delivering sufficient traction for continuous heavy rolling and uphill compaction work. Reinforced alloy gear pairs and double cone floating oil seals sustain reliable power transmission under constant construction impact loads. Precision ground gears reduce friction and wear to prolong service life; robust sealing effectively prevents oil leaks and mud/dust ingress on muddy, dusty job sites.
It works stably within -20℃ ~ +85℃ to adapt to all harsh outdoor construction conditions. Optimized three-stage planetary transmission achieves over 93% mechanical efficiency with low running noise, serving as a cost-effective, long-lasting travel reducer for CAT C-series soil compactors.
Q: Which machines fit this drive?
