1855 PTO

Yes you will need to drain the rear end. The pto shaft will need to be removed (don't forget to remove the o-ring behind the plug). After removing the lower support, the drawbar can stay on the tractor. When removing the pto get a piece of pipe that fits over the pto output shaft to help guide unit out. Be carefull unit is about 150 pounds. The spring on the pto can be compressed without the special tool by using a large prybar under the drawbar. While unit is out my suggestion would be to replace every seal, o-ring, & quadring. I did not replace the clutch discs while rebuilding my 2255 because they looked new & I will rarely use the pto.Another good idea would be to inspect the bearings & replace the seals where the 3 point goes into the rear. The worst thing about my rebuild was the heavy parts & the mess. I can help with part numbers if needed. Hope this helps, Stu.
