🔩 Differential Coupling – TATA / Leyland L/L (Serated, 76 mm Oil Seal)
📌 Applications
TATA Trucks: 4018, 2518 series
Leyland L/L Trucks: 4923, 4921 series
This part is used to connect the gearbox or propeller shaft output to the differential input. It ensures that torque is efficiently transferred to the differential while accommodating slight misalignments.
⚙️ Key Features
Serrated Surface (Serated):
The coupling flange has serrations (splines or teeth) on the contact surface. This provides positive mechanical engagement, prevents slip, and allows high-torque transfer from driveshaft to differential.
Oil Seal Fitment:
Designed for a 76 mm oil seal, which prevents gear oil leakage from the differential housing.
Material: Heavy-duty machined steel, hardened for durability under high torque loads.
Bolt Pattern / Diameter: Matches OEM specifications for the specific truck series.
🛠️ Function
Torque Transfer: Moves power from the driveshaft into the differential.
Positive Engagement: Serrated contact ensures a secure connection, reducing vibration and backlash.
Sealing & Lubrication: The 76 mm oil seal retains differential oil, ensuring smooth operation and preventing contamination.
Misalignment Tolerance: Serrated design accommodates minor misalignments between propeller shaft and differential input.
