🔧 Meaning — One Side Big, One Side Small (Rane Type Steering Cross)
In steering components for heavy Tata trucks such as Tata 2515, Tata 2516, and Tata 2213, the phrase “one side big, one side small” refers to a universal joint steering cross assembly where the two yoke ends are different sizes — one end has a larger hole/yoke and the other end a smaller hole/yoke. This design lets the cross fit into two different spline/yoke configurations in the steering linkage (for example, the gearbox side vs the drag/link side).
Rane Type: “Rane” indicates the style/standard of the steering cross — a common supplier/design used on many Tata commercial vehicles.
One side big, one side small: The part has one large yoke/eye and one small yoke/eye to match the differing shaft ends it connects.
🚛 Where It Is Used
It is used in the steering linkage universal joint assembly of the steering column for trucks like:
Tata 2515 (power steering, Rane type)
Tata 2516 (Rane/10‑wheeler type)
Tata 2213
This joint allows the steering shaft to flex and transmit motion smoothly through angled linkages and compensates for movement/vibration, basically letting the steering wheel control the direction reliably.
