How To Remove Bearing From GM Hub Assembly

[Music] all right guys we got another job we're about to start on here this is some more custom work that I'm going to be doing for someone local here and what what the customers want to do is adapt some Chevrolet parts to a Volkswagen and so they're converting what they want to try to do is convert these Chevrolet or GM parts over to fit on to the Volkswagen so we're having to make some modifications we've got a VW hub right here this is the stock original sizing and component and we're gonna be modifying these Chevrolet hubs and flanges right here to fit on the car and they're also going to be using this GM axle right there so got different things that we're going to do and I'll pull the camera down here a little bit closer so you can get a little better shot of what we're gonna do here all righty so there's the this is what the original hub looks like right there and I believe what all this started with is that they are wanting to run these larger GM size axles or Chevrolet I believe is what it is this is for drag racing stuff right here they've got a VW that they that they drag race and they're trying to beef up these components here to keep from breaking so they they come to me and asked if I could help with some of this machining that need to be done because this is all just kind of custom and modifications that we're going to be doing so this is the GM flange and a hub assembly right here so what we got to do is remove this bearing hub assembly off of the actual flange and I guess that would be the flange there that has the spline in there and so here's the here's the axle right there so that's gonna fit you know something like that actually I've got it backwards I'm sorry it's gonna go something like that right there all right so he's had someone else in town help him with one of these as they were trying to get this figured out on how they can make it work so we've got to remove this bearing right there so they've already messed with one and they were able to get it apart without a lot of trouble you just you know you got to have a lathe to be able to make this stuff easy to work with so we'll chuck this up in the inlaid there on this side and we're gonna come in here and we're gonna use the tool and actually cut away this area right there where they actually install this from the factory they cramped that in there so once we cut this away this should allow this flange right here this bearing assembly to be pulled off fairly easy and he actually supplied some bolts I don't remember where I said them now oh the bolts are right here I'm sorry I was looking around for so once we get this area cut away right there we should be able to use these bolt right here is like a jacking bolt and be able to screw those in there and actually push this bearing housing here off of the off of the hub so that'll be the first step right there and once we get all four of those off then we're going to modify these hubs and machine them to have this profile right here with a couple differences so they're going what they found the largest bearing that they could this is a 42 millimeter ID bearing so the bearing is gonna fit on there like so alright so two millimeters larger than the factory bearing that goes on there just trying to get as much meat inside of here as they can get so that was the the best bearing that they could find so we're gonna machine those 42 millimeters we're gonna profile these steps and registers in there just like that and make it so that this bearing fits we've also got a trim the OD of the flange this diamond right there we've got to trim that so that will fit the brake disc this is the brake disc that will be used on the car and you see it's too big to fit in there so all these will be modified so that you can buy these over the counter parts and fit on there without any problems and then the other deal is you can see where one of the bolt holes was welded up so we've got a machine the proper a four lug pattern in these flanges for the VW wheels which I believe I got it in the notes it's for about 100 millimeter I believe so usually anytime you you're trying to go from a 5 to a 4 or a 4 to a 5 if you're within the same bolt circle diameter and you were close you're one of those holes is going to collide with the other so you got to you know weld up one of your holes and so you got a good place there to drill so he's already taken that and welded them up and ground them down even and they did a pretty good job right there you know so that's we're not gonna have to do that so that'll be later we'll do that in the mill and I believe that's it that's going to be the gist of what we got to do so we'll go down to the monarch we'll use that and start seeing how much trouble it is to get one of these bearing assemblies off off the flange all right these situations like this you know flying into something like this blindly you're not not really sure what you're going to come across so I went ahead and I wanted to start the first one so that I could figure out what exactly is going to take place to get this thing apart so and I'm glad I did because it was a lot more metal removal than what I thought so this is the first one right here and you know I never mess with these before his first time that I've ever had to actually get one apart up just never had to mess with it so this area right in here has been it's from the manufacturer somehow they pressed this over or roll it over somehow to capture this in there so this has to be machined down not that this is just a metal keeper that holds that seal up in there but this has actually got to be machined down a little bit so we'll get this cover this will shield off out of the way and then we'll go in there and actually machine this away we'll have to get into the bearing race as well so it's a little bit involved but now that I got one of them one of them apart I kind of know what what to expect it is gonna blow through some carbide and I've got plenty of extra carbide inserts around here that I'm planning on using for this they have been given to me so not too much worry of you know messing up good carbide inserts so we're gonna put an indicator on this flange right here and make sure that the flange is actually running nice and true we're going to use my steroid attachment right here to get in there on this flange make sure that I'm clearing here so we want to get in here on the highs and bump them around a little bit like it's got a low so that's the world I'm looking at there okay that's looking like that's going to be pretty good right about there so we'll move the indicator and I'm going to retort the Chuck make sure that it is good and tight okay all right so we'll get in here with this little braised on tool and see if we can get this little shield popped out of there not that it's really all that critical but first one I did just kind of fell out of there there we go all right so that's that's some kind of little that's hot that's some kind of little metal shield that they press in there over the top of the oil seal there so now you can see we're going to this is the bearing race right here but we've got to remove some of this right in here as well to get this to come off there that's gotta get my ear plug that stuff squeals that's the tool that I was using last right there I'm just going to use it up until it burns it up which it will [Music] I'm just gonna turn it back a little at a time if you go too fast it it'll just burn that carbide up in a second so you just got to run it nice and slow I just go back until it catches this hub like that making sure that it's yeah we still got a tool there [Music] all right it's got that edge I don't have to turn that insert around this is a box of inserts that Keith Fenner had given me the just a whole box full so when you got plenty of inserts like this you know you can you can afford to kind of go through and burn this stuff up so I'm going to use some of these to cut this see if this tool will work [Music] not doing much better than any of them you can kind of see in there now what I'm talking about this they say it goes down in there this this area here is sort of like a flange to capture this race [Music] all right let's change that corner around cuz it's already burned up to get the bearing to press off there you got to be below 1 inch 850 so we're just about there now I'm going to take some more down think it'll press off now let's go ahead and give it a try we'll put our bolts in here and see if it'll push off now it's not want move I have to take a little bit more I might not be back far enough I mean I didn't face it back as far as I did on that first one let me take some more off there before I do this I carbide it's not holding up at all I think that gold color when I was using before was working better than these those are chipping away [Music] [Applause] there we go I think we might have it this time yep there we go you just got to get it down to the right area probably better if I go get a ratchet I might do that for the next ones get it past this this front race here it'll fall off there here comes all right there it is and there's the race [Music] and that's it kind of a funky setup so now now you know what they mean by you know replaceable hubs no you know most cars now don't have rebuildable hubs hubs like this this is why they're they're permanently put together and when they fail you throw it away and you put another one on there all right so that's one down and I got to show you that one so there's really no need to show you the other two I'm gonna go ahead and get those two done and get us all four of them down to this level right here
