To some people this might seem as a silly idea,but it really works.
Pressing out the pilot bearing is pretty messy,and it requires grease,which makes it even more messier.So grease gets pumped into the hole and acts as a hydraulic ram,to press the bearing out.As shown In the video,looks like this nightmare is finally over.It looks like a piece of bread can do the same thing as the grease does,pushing the bearing out while it’s a lot easier to clean up once is out.
