COMPLETE REAR AXLE DIFFERENTIAL (HOUSING + SATELLITES) SUITABLE FOR JCB - 450/10900

Technical Specification and Compatibility

A critical drivetrain component – this is a complete rear axle differential assembly. It is a ready-to-install sub-assembly containing both the differential housing (carrier) and the internal gear set (satellite and spider gears). It is responsible for transferring power from the pinion gear to the axle shafts while allowing the wheels to rotate at different speeds when turning. Designed for a wide range of JCB machines, including 3CX/4CX backhoes, loaders, and JS wheeled excavators.

Part number: 450/10900
Application: Rear Drive Axle
Contents: Complete housing with satellite gear set

GX-AFTER is the smart choice for your machine. We provide high-class replacement parts that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

Essential for Installation

  • › HYPTRON Axle/Gear Oil: Essential for refilling the axle after repair.
  • › Differential Bearings: It is highly recommended to replace the carrier bearings.
  • › Axle Shaft Seals: A perfect time to replace them to prevent future leaks.

Application in machines

Brand Type / Series / Model
JCB Backhoe Loaders: 3CX, 4CX
Telehandlers (Loadall)
Wheel Loaders
Wheeled Excavators: JS130W, JS145W, JS160W, JS175W
Rough Terrain Forklifts (RTFL)

The list above is for reference. Please verify the part number before purchasing.

⚠️ Installation Warning

Installing a differential is a precision operation. The inside of the axle housing must be kept perfectly clean. Any metal filings left from the old failure will immediately destroy the new mechanism. Installation requires setting the correct backlash and contact patch with the pinion gear.

Part's Role in the Machine and Failure Diagnostics

The differential allows the wheels on the same axle to rotate at different speeds, which is essential for turning. Its failure usually manifests as loud metallic noises from the axle or a complete loss of drive.

  • › Loud "whining", clunking, or grinding from the rear axle, which gets worse on turns.
  • › Wheels locking or binding when turning on hard surfaces.
  • › A sudden, loud bang followed by a loss of drive (due to shattered satellites or carrier).
  • › Large amount of metal filings in the axle oil during service.

🔧 Expert's Guide: Key Installation Tips

  1. System Cleanliness: Before installing the new differential, you must clean the entire axle housing of old oil and metal debris. Failure to remove debris will destroy the new unit and void the warranty.
  2. Replace Oil and Bearings: Always install a new differential with new carrier bearings and fill the axle with clean, new gear oil (e.g., HYPTRON) of the correct specification.
  3. Set Backlash: The most critical step is to precisely set the gear backlash and contact patch between the new differential (ring gear) and the pinion gear. This must be done by an experienced mechanic according to the service manual.
  4. Inspect Axle Shafts: Before installation, check the condition of the splines on the axle shafts. Damaged splines will destroy the spider gears in the new differential.

Frequently Asked Questions (FAQ)

1. What are "satellites" in a differential?

"Satellites" (or spider gears) are the small gears inside the differential carrier. They rotate on their own pins (the cross pin) and mesh with the side gears (crown wheels) that are connected to the axle shafts. They are what allow one wheel to turn faster than the other during a turn.

2. Does this differential include the ring gear?

No. This product is the complete satellite carrier (housing + satellite gears). The ring gear is the large gear that this assembly bolts into. The ring gear is typically replaced as a matched set with the pinion gear.

3. What happens if the "backlash" is set incorrectly?

Setting the backlash (the small gap between the ring and pinion gear teeth) is critical. Too little backlash will cause the gears to bind, overheat, whine, and seize. Too much backlash will cause a loud "clunk" when accelerating/decelerating and will eventually chip and destroy the gear teeth.
