say a bearing splitter sell these at a harbor freight just get this guy open and basically the set they give you at harbor freight you've got two different size splitters with the malt heads and stuff you really only ever going to use this one that's for cars and stuff like that but so basically well this I've got a E50 crateshaft here that's obviously unusable anymore but this would be if you wanted to pull that bearing out the crateshaft and that that's things up you use one of these guys and so what you'll do is you'll loosen this up so that goes on there and next I'm going to want to tighten this back up so I've got that nice and tight on there but it's good as I can get it and the next thing we're going to do is we're going to grab these guys out of here just a little shafty things these just go in here and then I'm just going to take these nuts and washers off and then I'm going to want to grab this guy this just sits on here like this then nuts and washers go back on and I don't want to snug these up quite yet just kind of get them on there and then I'm going to grab this big long threaded shaft see the reason we left this loose is because we want to be able to center the shaft on the crateshaft just like that and so then the next thing I do is so as we crank on this it's going to pull up on these guys pull the bearing right off the shaft 17 millimeter wrench that we're going to put over here and so I'll just crank in on the shaft deal here hold this with one hand it'll pull it right up and so now that I've got that loosened up just pull the whole thing right off that's it
