This half PTO (Power Take‑Off) assembly is designed for the tractor end of the Shaktiman rotavator drive train, specifically for the 38 mm cross (1210 cross) shaft dimension, using an outer‑lock coupling style. According to the parts catalogue, item code UJ‑84 corresponds to “HALF PTO ASSY. SPRING PIN TYPE WITH COVER 38MM CROSS OUTER LOCK TRACTOR END SHAKTIMAN ROTAVATOR”.
Key features & fitment details:
-
Spring‑pin type: The assembly uses a spring pin mechanism which acts as a safety element — under overload or obstruction the spring pin will give way first (shear/disengage) thereby protecting major drivetrain components.
-
With cover: Comes with a protective cover/guard to shield the PTO parts from dust, debris and reduce exposure to hazards — increasing safety and longevity.
-
38 mm cross dimension: The specified size for the cross/tube in this system is 38 mm (also labelled “38 mm – 1210 cross”) for Shaktiman models.
-
Outer‑lock coupling: The coupling mechanism employs an outer‑lock style, meaning the lock is external to the shaft/bore instead of inner. Fitment must match this style to ensure proper connection and safety.
-
Tractor end: This assembly is for the tractor side of the drive (not the rotavator end). So ensure your machine’s configuration uses this specifically.
-
Compatible with Shaktiman rotavators geared for 38 mm cross‑shaft outer‑lock systems.
Usage & installation notes:
-
Before purchase/installation: Confirm that your equipment has a 38 mm cross shaft and employs an outer‑lock type coupling on the tractor end. Mismatches (e.g., inner‑lock style or different cross‑size) will cause mis‑fit or drive failure.
-
Inspect the current coupling, universal joints, tubes for wear, play or damage. This part will fit correctly only when the rest of the system is healthy.
-
When installing: Ensure the cover is installed properly and fastened securely; check that the spring pin mechanism is intact and correctly engaged.
-
After installation: Test under light load initially; verify there is no excessive vibration, play, or unusual noise — these could indicate misalignment or incorrect fitment.
-
Because this is a spring‑pin type safety part, keep spare spring pins handy for future replacement in case of overload situations.
