IMPORTANT INSTRUCTIONS FOR REPLACEMENT:
• Remove the installed Locking Pin housing from the tractor coupler with vise-grips or 5/8” open-end wrench. Heat
may need to be applied to the Locking Pin’s housing and coupler threads for removal.
• Apply Loctite® Threadlocker Red 271TM to the threads of the Tractor Coupler and the Locking Pin to prevent
backing out.
• Wrench the replacement Locking Pin into the Tractor Coupler and torque it down.
• Wipe away excess Loctite® Threadlocker Red 271TM from the top and bottom of the Locking Pin.
IMPORTANT SAFETY NOTE: Always install the stand-alone PTO Link® SD System - Safety Plunger Pin (SLIC PinTM) after
connecting the PTO Link® System Couplers.
Optional Information:
Coupler Connection Tip – When using the tractor’s freewheeling PTO feature, rotate the tractor coupler clockwise. If
only the implement turns, rotate the implement coupler counterclockwise. If both the PTO and implement turn, both
couplers can be rotated simultaneously.
