How to remove the clutch from your Mercedes M113k Supercharger E55 SL55 CLS55 AMG Kompressor

get everyone this has been from Ben's performance parts I'm gonna make you a video on how to remove the clutch on the e55 SL 55 mercedes-benz anything with a m113 k compressor so basically this unit here is what I call the clutch and it is pressed on to the inner shaft which is inside here of the supercharger now these two what you call interference fit which means that the shaft is bigger than the inside hole of the clutch so I have explained in many people how to remove this and some people have a lot of trouble with it it shouldn't really be that hard so I thought I'd make a video on what's going on and what to watch out for the tricks basically so this is what I've removed earlier to give you a bit of a better idea so this is the inner shaft there is a seal here as well I'll get to that later this is the magnet and the magnet magnetizes through this unit and your clutch on the back of the pulley engages here so this is what the shaft looks like so going back to this unit here which is still in one piece this is just a basic 150 ml pour and you basically need to secure it on the inner shaft of this and then what you're going to do is heat this part here all the way down in here because on the inside of this is where you have to actually expand it so you have to get right the heat right in that step unit in there which is there here so for this I recommend propane this is one of the hottest blow torches I could get as a portable blow torch and if you've got bigger it might work better but if you don't have a hot enough torch basically what will happen is you'll heat this up but it'll take so long that this shaft will also heat up and they will bind so they're already bound together due to the interference fit the concept is that you heat this quick enough it will expand and you'll be able to remove it off the shaft with minimal effort so commonly what happens is people get a puller and they just crank on it and crank on it and crank on it and they end up bending this elbow a section here and breaking the clutch and then it's throw it in the bin time so what you need to do is put enough tension on this that it just starts to load the shaft up and I'd say it's probably 15 or 20 Newton meters just hang on to the wrench right at the head and just turn it and you just need to put a bit of pressure on it so once there's a bit of pressure on there you need to get the blowtorch and run it around this section all the way around it and get it really hot really quick it's good to have a welding glove well will because everything's going to get hot so what happens is once you heat this up and it's already under tension you'll hear it go pop and the pulley clutch will start coming up now you'll feel it straightaway when I go is pop the tension will disappear all you need to do is wind the tension back on and keep the heat on it if it cools or if you take too long and inner shaft heats up it will bind so if you get halfway up and it stops you have to completely stop the whole process wait good few hours till it's cooled down and start again because what's happening is you've heated the outside up so much that you've then entered heated the inside shaft and they are now interference again this is where people get stuck there you're halfway off the jams they just persist and persist and keep all and they destroy the clutch all the shaft so again this is what the shaft looks like once it's come off and this is one I have removed and it's in quite good condition there will be some slight marks in it but that's fine and yeah so once you have heated this unit up there's a good chance you're going to destroy this seal or I recommend changing this seal anyway because once you're in there you've read it on the hard work so you can get a peek in there and you can pull that seal out it shouldn't be too difficult most of them leak by that sort of age anyway and this is what another common problem that happens so this is a good shaft that the bearing sits on on the pulley you can see still got like a bronze this color from its machining originally you can see the machine marks in it I've got this one here that was already worn so this is what a worn one looks like so the bearing inner sleeve itself had worn the bearing must have been in very very bad condition and it has worn here so badly that you put a new bearing on there and it just swaps around and dances around so that's a paperweight okay part two you've taken this off you you've done whatever you need to do you've changed seals bearings whatever you want it to do if you're putting a fixed pulley on there you you're gonna do that if you're gonna put this back on the best way to do it is the same in Reverse so you can put this in the oven and heat it up it's gonna have to probably be very hot I'd say 200 degrees maybe more some people could choose to try and put this in the freezer but I haven't had much luck with freezing and heating the reason is when you put the two together I find it's a rapid change in heat and it binds very quickly you might have luck with it if again if you get stuck you're gonna have to pull it off don't don't try and jam it it's just not gonna work so basically what you're going to do is this is going to be hot you know put it back on there you're going to have your blowtorch and you're going to keep this hot and then you're going to carefully tap it down now I've put some decent marks in this one before because I've used a hard hammer or I should have used a soft hammer once it is the correct temperature and it's warm enough it will start tapping down quite easily there is dowels in it now some people are leather dowels they will just pull out Dow's there they will pull out when you start the job now to put them back in you need to line them up so those dowels on the end of this and the styles are moving into the clutch and the catch is you have to manually line them up by eye before you put it down because if you put up with this by the time you get to the bottom there is no chance and you bring those to house and you can't rotate it it's too late so same process heat gently tap it down if you smack this with a hard hammer when it's hot all you're going to do is to form this outer side and you're never going to be able get the bearing back on it so this is hot if the shaft itself isn't too hot yet it will go down quite easily once you get it down let's say half way three-quarters away you can put this actual bolt back in it and you can pull it in the last bit with the bolt that works really well and it pulls it up nice and tight so there is a shoulder shaft and that meets up with this machine section on the inside and basically what it comes home you'll notice that it'll be flush again like this one or just about so hopefully let us shed some light on taking these clutches off these units I've had a lot of people getting strife with it and it's really because they either they rush it and they don't have enough heat and then basically the two shafts bind so yeah if that does happen just stop wait do it again maybe try a bigger blowtorch with the correct heat I can probably get one of these off in under a minute so once it's hot it just is a case of it going pop and you wind it and keep heating and it will go pop and you wind it and keep heating it like I said a welding glove is a good idea or some sort of heat proof glove because by the time you have 3/4 of the way off it might start to tip or walk or your puller might become loose and at that point you're going to want to touch it because you're already dedicated and you don't have a glove you're gonna burn yourself so this whole puller everything is going to be red-hot your sockets everything and yes you know you're going to want to touch something eventually so it is possible to do at home with a bit of care you don't need any special degrees and in engineering or mechanical know-how you just have to have the right technique and patience like I said this is a like $40.00 pool it's very basic you can get them just about everywhere and yeah this is a propane blow torch from a HUD hardware store and that's all you need you can do this on the car it is a little bit more tricky but you actually can get this in around all the gadgets that are in there and I've done I've done a couple of the carved on a couple off the cards a lot easier off it but if that's the only job you need to do you don't have to take the supercharger off to change the front of it and put it back on you can do it while it's on the car hopefully this is cleared cleared up a few things if you have any questions shoot me a message Facebook or through YouTube and hopefully I can help
