Product Overview

 

203 4710 planetary final drive gearbox is OEM replacement wheel side drive assembly specially matched for Caterpillar CS76 CS79 vibratory compactor. It adopts three stage planetary reduction structure with built in wet multi disc parking brake to convert high speed hydraulic power into low speed high torque output for steel roller walking system. All mounting flange oil port and brake interface keep fully consistent with original compactor parts so users can finish direct replacement without extra cutting or modification. This heavy duty drive unit can stand long time continuous compaction impact and dust mud environment as reliable hydraulic spare part for road construction machinery.

 

Product Features

 

  • High strength alloy steel planetary gear set delivers stable large output torque with strong resistance to heavy load and frequent vibration from road compaction operation
  • Built in anti slip parking brake locks roller wheel firmly when hydraulic supply stops avoiding equipment sliding on slope construction ground and improving overall operation safety
  • Complete high temperature sealing assembly effectively prevents hydraulic oil leakage under dusty muddy outdoor road building working conditions
  • Maintains stable transmission efficiency under standard construction hydraulic pressure supporting all day long continuous heavy duty compaction work within wide ambient temperature range
  • Integrated compact structure combines reduction load bearing and brake function in one unit to simplify installation steps and lower machine maintenance time cost
  • Surface anti rust black oxide treatment extends whole service life of gearbox its purchasing cost is much lower than original factory spare part to reduce road construction team equipment maintenance budget
  • Perfectly matched with mainstream hydraulic piston travel motor fully compatible with Caterpillar CS76 CS79 vibratory soil compactor original hydraulic pipeline layout

 

Application scenarios

This 203 4710 planetary final drive gearbox is exclusively designed for Caterpillar CS76 CS79 vibratory compactor used in highway foundation compaction city road asphalt paving rural road reconstruction and airport ground leveling projects. It also fits all kinds of medium sized single drum vibratory compactors working in open air road construction sites that need stable low speed high torque walking power to finish soil and asphalt compaction tasks.
