PLANETARY HUB SUN GEAR SUITABLE FOR JCB 3CX, 4CX - 454/07401

Technical Specification and Compatibility

A heavy-duty sun gear, a key component of the planetary gear set in the drive axle hub. Its function is to transfer torque from the axle shaft to the planet gears, thus achieving gear reduction and multiplying the driving force. Precision-machined teeth and splines guarantee a perfect fit and resistance to shearing.

Part number: 454/07401
Alternative part numbers: 450/12403, 450/10210
Number of teeth: 15
Number of splines: 33
Height (mm): 45

Aftermarket quality product – an intelligent choice combining excellent quality with an attractive price.

Application in machines

Brand (Machine Type) Example Application
JCB (Backhoe Loaders) 3CX, 4CX (equal-sized wheel models, axles SD55, SD70, SD80)
JCB (Telehandlers) Loadall (wide range of models)
JCB (Wheel Loaders) Various models
JCB (Other Machines) JS Wheeled Excavators, FASTRAC, RTFL Forklifts, Vibromax Rollers

The list above is for reference. We recommend verifying the number of teeth and splines on your machine before purchasing.

Service Recommendation: Ensure Maximum Lifespan

A hub overhaul is the perfect time for a comprehensive axle service. Always replace the sun gear together with a full set of planet gears and bearings. Fill the axle with new, clean HYPTRON gear oil and replace the hub seals to provide the new parts with ideal working conditions.

Part's Role in the Machine and Failure Diagnostics

The sun gear is the central and most loaded component of the planetary gear set. Damage to its teeth or splines leads to the "grinding" of the entire hub, loss of drive, and can result in the wheel locking up. It is one of the most serious failures of a drive axle.

A hub rebuild is necessary if you notice:

  • A loud, metallic grinding, banging, or "milling" sound coming from the wheel hub.
  • Sudden wheel lock-up or a complete loss of drive.
  • A large amount of thick metal shavings in the drive axle oil.
  • A noticeable "jumping" in the drivetrain when starting off.

Expert's Guide: Key Installation Tips

  1. Always replace as a set: Never install a new sun gear with old planet gears. Worn planet gears will immediately damage the new sun gear. Always replace the entire planetary gear set.
  2. Maintain perfect cleanliness: Before assembly, thoroughly wash the hub housing and all cooperating components to remove old metal filings.
  3. Check the bearings: Always replace the planet gear needle bearings and the main hub bearings along with the gear set.
  4. Use new oil: After the overhaul, fill the axle with new, clean oil of the correct specification to ensure proper lubrication.

Frequently Asked Questions (FAQ)

1. I found a lot of metal shavings in my axle oil. Will replacing just the planetary hub be enough?

Replacing the complete planetary hub is necessary, but that's not all. The filings circulate throughout the entire axle and could have also damaged the differential and the pinion shaft bearings. After a planetary hub failure, it is recommended to disassemble and thoroughly clean the entire axle.

2. How can I differentiate between a planetary hub failure and a differential failure?

A planetary hub failure usually manifests with noise and problems with one specific wheel. A differential failure (spider gears in the carrier) most often manifests with clunking noises when turning, as the wheels need to rotate at different speeds.

3. I have a 3CX with small front wheels. Will this part fit?

No. This model of sun gear is intended for larger axles (e.g., SD55, SD70) used in machines with equal-sized, large wheels (3CX Super, 4CX). The standard 3CX model has smaller planetary hubs and requires different parts. Please contact us to verify.
