SHEARING+TRIANGULAR YOKE+38MM CROSS ROTOVATOR END OUTER LOCK SHAKTIMAN ROTAVATOR

This kit‑type assembly combines a shearing yoke and a triangular yoke designed for the 38 mm cross‑section, outer‑lock power take‑off (PTO) coupling system used on Shaktiman Rotavators. According to the parts‑catalogue listing, item code UJ‑81 corresponds to “SHEARING + TRIANGULAR YOKE + 38MM CROSS ROTAVATOR END OUTER LOCK SHAKTIMAN ROTAVATOR”.

Key features & fitment notes:

• Intended for the rotavator end (i.e., the implement side) of the PTO/driveshaft system, not the tractor end.

• “38 mm cross” refers to the cross section dimension commonly used on Shaktiman PTO shafts (also described as “38MM – 1210 CROSS”) with outer‑lock style coupling.

• The shearing yoke portion functions as a sacrificial or overload‑protection element: under excessive load conditions it will shear (break/fail safely) before the more expensive gearbox or drive shaft is damaged.

• The triangular yoke portion ensures torque transmission through the triangular coupling shape, which matches the triangular tube or shaft profile used in the system.

• Outer‑lock type means the locking mechanism (such as a lock‑clip, external pin, collar) is external rather than internal—so ensure your existing system uses that style.

• This combined assembly helps maintain correct alignment, fitment and functional safety of the PTO/rotavator connection, especially in heavy‑duty tillage operations.

Installation & usage tips:

• Confirm your machine uses a 38 mm cross (match your current shaft or coupling bore).

• Ensure your coupling is outer‑lock type (not inner‑lock or other styles).

• Replace both the shearing yoke and triangular yoke as a set if one part shows wear—since mismatched new vs old may cause irregular load distribution.

• Check the mating shaft/tube for wear, play or damage (especially the triangular profile corners) before installing a new yoke set.

• After fitment, test the rotavator under light load, check for play or vibration which could indicate misalignment or incorrect fitment.

• Keep spare shearing yokes on hand if you routinely work in heavy conditions, since they are designed to fail under overload to protect other components.
