Well, you got a doozy there. The video was extremely helpful. Thanks for posting.

I don’t know if any of this will work. But it is some of the redneck engineering I would try first.

First attempt, wrap 1/8 nylon twine, mason’s cord, or nylon rope around the shaft behind the fan hub. Put five or six wraps on the shaft so that the cord will tighten as you try to loosen the bolt. IIRC correctly the bolt is 1/4 28 right hand. Of. Course tie the cord to the cross member to hold it as you turn the bolt. You may have to apply tension to the loose end to make the cord grip. Imagine how a capstan works.

Second attempt. Buy a 1 1/2 or 2 inch wide piece of 1/8 or 3/16 flatstock at ACE or Lowes/HD. Cut a v notch in the end. The deeper the V, the more grip it will have. Wedge the v onto the shaft.


Third option, by far the most work, but almost guaranteed. Remove the two bolts that hold the hyd motor to the overhung load adaptor. The motor is heavy so be prepared. The motor shaft is splined and will slip out of the OHLA. This will give you access to the back of the OHLA. However the back of the OHLA shaft will be a female spline fit so you will have to wedge something (brass or aluminum to keep from messing up the splines) into the back of the shaft to keep it from turning.

Fourth option. You could remove the in and out lines on the hyd motor and cap them, effectively locking the motor. However, those lines are below the reservoir, so when taken loose, all the ATF in the reservoir is going to drain. BIG MESS.

Fifth option, use an oscillating saw and cut the plastic hub into two or three pieces so you can remove the fan from the shroud.



Maybe this will spur some creative solutions by other gurus.
