🔩 Flange – TATA / LPK / Leyland L/L (Serrated)
📌 Applications
TATA Trucks: LPT 3127, 2527
TATA LPK Series: 3128
Leyland L/L Trucks: 3123
This flange is a critical driveline component that connects the gearbox output or intermediate shaft to the propeller shaft, centre coupling, or differential flange.
⚙️ Key Features
Serrated / Splined Surface:
Provides positive mechanical engagement with the mating flange or yoke.
Prevents slip under high torque loads, reducing vibration and backlash.
Material:
Manufactured from high-strength alloy steel, often heat-treated for durability.
Bolt Pattern & Fitment:
Designed to match OEM specifications for TATA LPT/LK/Leyland driveline systems.
Bolt-on installation ensures precise alignment and torque transfer.
Maintenance:
Works with the driveline lubrication system and may include a matching oil seal depending on the position in the shaft.
🛠️ Function
Torque Transmission: Transfers power from gearbox or intermediate shaft to the propeller shaft or differential.
Positive Engagement: Serrated surface ensures the mating flange or yoke is locked under torque load.
Durability: Designed for heavy-duty truck torque, vibration, and shock loads.
🔹 Driveline Placement
Gearbox Output → Serrated Flange → Propeller Shaft / Centre Shaft → Differential Flange → Axles → Wheels
The serrated flange is essential for connecting rotating shafts while maintaining alignment and torque integrity.
