📌 Description — Half Yoke “Magic Long Spicer Type”
A half yoke in a driveline (propeller shaft or Cardan shaft) is a component that connects one end of the propeller shaft to a universal joint (U-joint) or another mating yoke, enabling torque to transfer through angled, rotating shafts while accommodating movement and vibration.
When specified as “Magic Long Spicer Type” this generally means:
✅ It conforms to a Spicer-style universal joint yoke design — a widely used, hardened steel U-joint and yoke standard favored in many commercial and heavy-duty drivetrain applications. The name Spicer originates from the Spicer brand and is commonly used to describe this type of universal joint system (often also called a Hardy Spicer joint).
✅ “Magic Long” indicates it is a longer version of the half yoke used on Tata Magic (or similar light commercial vehicles), providing additional length on the propeller shaft side for specific fitment or vibration control requirements.
🛠 Function
Connects the propeller shaft to the U-joint: Half yokes hold the universal joint cross (spider) at one end of the driveshaft.
Allows angular motion: The U-joint assembly permits movement between shafts at an angle, accommodating suspension travel and misalignment.
Torque transfer: Designed for reliable transmission of engine torque from the gearbox through the propeller shaft to the differential.
🔩 Design & Material
Typically forged steel with precision-machined surfaces for strength and durability in commercial vehicle applications.
Paired with matching Spicer-series U-joints and companion yokes for proper fit and long-term service.
🧰 Where It Fits
In the propeller shaft assembly of vehicles like Tata Magic (especially older or specific variants), the half yoke attaches to the shaft and works with the universal joint to connect to the gearbox output or rear axle.
