Heavy Duty replacement part for the Operating Shaft Assembly & Pivot Block.
The original operating shafts are often bend. This one (the part which connects both worm shaft and operating shaft) is made from a thicker material so this will not happen. You will most likely don't need the thrust washers (Part Number 116-A4) anymore.
You will have to make a hole into the operating shaft (there is a hole in the pivot block which you can use as a guide) to get the correct angle for the pivot block and engagement leaver. I have not done this yet, as most engagement leavers are extremely worn. You can make the hole in the exact position you need.
