okay hello and welcome back right so I've got a piece of belt on here and I got a welder and it's writing team four and I'm not cooking chicken in this what I'm actually doing is going to show you a trick which will help you remove bearing races if you don't have the correct puller this is an age-old trick and you have to do it quite cool and simple that's wrapped around this tip carrier and it's just to make sure there's no splatter goes around if while all your weld around at the bearing race now the whole idea is to get this race so you've got a couple of tabs on it so you can then put a puller on it and pull all the bearing rice off like so the problem is is with our pullers we don't always get the right types and unless you're going to pay a lot of money for the specific puller for the job right so I do a lot of trailer hubs and the bearing races inside not on this one because they're easier to punch out but I usually weld them out then just tap them out drop another racing very quickly easy to do now this is a div carrier and basically I've taken the rollers of this so we have this bearing left on here now you have two tags here which you could pull the races off however we don't have that specialist tool you can see the pegs here you possibly could weld around it and then chisel it off that's an option especially since weld heat set up what we have here is the input gear of the LT 230 now I've put a ringer weld around there and I was actually knocked off with a hammer because it was that loose and I left it to cool down so I put an extra couple of tabs on it and I'm going to pull it off it should be easy enough to do but I'm going to show you about this so you sort of generally get the idea some of you straight away already know what to do so not a problem but the others bear with me right so this is my puller set and I have an extra set here which obviously these legs are a little bit too chunky and also in this kit as well after three legs and a two leg puller with extensions and of course a thread now and yeah they're practical up to point but I will show you why in a minute now these are bearing pullers the ones with the ball bearings you actually get more force if you have a ball bearing on here as it's not causing friction against metal surfaces but you need a boss to put the ball bearing in and you should be aware of this if you've pulled the current on your 300tdi you'll know what this is all about because you have a boss in the kit down yeah so looking at this gear we have to make up as we go along 27 bill socket which will fit against our splines there and then the 27 mil security socket now it has a live space here which the ball bearing will fit in just nicely and this is what we're looking for sockets and bits and pieces that you've got in your toolbox that will be of use so the other thing is the feet will not latch behind it very engaging possibly pull this on three sides and actually pull the bearing off and you see that very clearly there so the best thing that there is to actually cut the cage and get rid of the rollers so you'd end up with the other part of the race here now this is workable now this diff carrier has a peg as I said but unless you cut your Pollock it is going to be a problem now we also have bearing clams or clamps as they're called I'm not actually sure they're called bottle and clams and basically what we do is put them underneath the bearing and then pull but you've got to have loads of different sizes and this isn't the right size for what we need so that goes back in the kit if we're going to do any welding obviously we want to make sure that we don't damage the gears or any of the mating faces so we use a tin foil and tin foil keep changing it if you're doing a lot of welding and you keep the amperage very very low I'm using a 2.5 mill something like 70 amps and I'm not really putting too much heat in it and what doing is I'll put a couple of runs in it and then let it cool down and then do it again basically you've got a weld evenly so you don't distort at all and you can see the world is running on 70 amps there and what I've done I actually run it weld all the way around and then put two tags on it and what we'll do from there you can see it steaming hot what we'll do from there is cut some slots in it with a grinder now I'm not going to cut with the grinder and show you because I got the sparks on a lens but just take it from you use a grinding disc and make sure you cut some square flats as it were so we can pull on two sides you could do this evenly for three legged pullers not an issue this one will come off with a two-legged puller so you can see where the grinder has been and you can see where the leg will now fit in and it will grip this is what we're after we need something to pull on so I've made myself with a socket that fits and a security will nut and I'm using a bar to push against so that's on the bench and I'm using this too to lock it down so I'm not going to struggle and basically yeah just use a bullet and winder off and I'm just now demonstrating that the fuller will actually pull okay and you can see that easy so hold the threads and I'm now just going to chuck a little bit more oil in there just to make sure we have at less friction and it helps to extend the life of the tool so basically they would go just wind it off and it is bearing race off so what the difference is is I've not damaged this in any way whatsoever it has been slightly hot and none of the areas which are working surfaces have been damaged now I did actually catch that with the world I'm going to have to clean that and on this one which is the gear for the transfer box that came off a very very easily and you just got be aware not to put too much heat in it so something like this obviously we have issues because of the length and the input shaft of the are 380 is about foot long 300 millimetres 30 centimetres and basically you need legs that are just a bit over unfortunately the kit I have won't do it as you can see here which is another two if you're bearing for instance goes on the piece it makes it more awkward to pull the whole idea of using a puller is to pull it evenly you can actually see that the leg is not evenly distributed once you pull it a little bit you can get the legs underneath the bearing race and then pull it the rest of the way evenly so that's easy enough one more tip here is to make sure that you haven't got the edge of your socket over the bearing race for instance otherwise that will not pull off and you'll just end up breaking your tool so find the right socket for the job to do all right so I hope that's been helpful for you just remember to take care and not hurt yourself when you're putting bearings
