Combines Tbran need a little help

Yes it turns to tighten so as not to screw itself off in operation. We have found the easiest although not simple way was thus. We took an old 3_4" drive socket and welded 3 bolts to the outside to line up with the 3 slots in the pulley. Thus the 'special tool'. Taking a pipe wrench to secure shaft and after heating the pulley around the hub, a pull of the trigger seldom fails to spin off the pulley.. In case of seldom, an air chisel in combo with the impact works. In the field away from impact wrench help, a long breaker bar and a sledge hammer makes a poor mans impact. Keep in mind lefty tighty righty loosy here. The equal force by the 'tool' is important and takes only a few minutes to fabricate with a sacrificial socket. A half inch will work in lieu of 3_4 if breaker is of good quality. A few hail maries don't hurt before the big pull either

Thanks for the help Tbran. I guess now I will see what kind of junk socket I can round up. I will let you know how it worked. Thanks

i couldnt find a socket to use so we just welded an 1" nut to the plate and use a socket on that
