Replace DAMAGED Caps on Caterpillar 815 Soil Compactor Wheels | Welding & Arc Gouging

[Music] come on how you going guys Kurtis from cutting edge  engineering today's job and for the next couple   of days we're going to be working on some 815  soil compactor wheels so these wheels are off   an 815f soil compactor there's four of them on  a machine these are commonly used on building   sites compacting roads compacting ground for  new infrastructure the customers brought them   in it's got holes in the caps they're all worn  away the main reasons they wear away is what they're  compacting can be quite quite abrasive uh full of  rocks sandstone pretty much any any sort of dirt   can end up being pretty abrasive the main drum  of the machine is made up of five parts we've   got the outer skin that's a bit of 16 mil 350  grade plate we've got these side cones there's   one on each side they're about eight mil thick  as well the inner drum is 10 mil thick and the   inner flange that bolts onto the the diff  of the machine this is actually a rear drum   and then we've also got the pedestals and the caps  on this particular set of wheels we have a set   of wear bands on the inside of the pedestals so  these do cop quite a lot of abrasion they do fill   up with dirt and there is a scraper bar finger  that sits in like that to actually remove all the   dirt that gets caught in here uh quite often it  will end up wearing a hole right the way through   through the drum these drums have already been  beefed up a little bit by the previous owner of   the machine from what the customer was telling  me so first part of the job is we've got to   gouge off all these caps there's there's 60 on  each wheel 240 in total uh after we gouge them   off we've got to grind away where the weld  was on the pedestal so that that there's a   pedestal once we get all that done we can start  fitting the new caps to the wheels and start and   start welding them out right oh so these are the  pedestals that are attached to the drums there's   60 of them in total they're just a hollow cast  part they're a pretty good material to weld to   they uh they fit the drums really really  well these are actually after market   but pretty good quality so if ever we need to  do a pedestal replacement we end up buying 240   of these and these are the caps so you can see how  much material is missing off of the original caps the caps are also cast not sure where pretty  good casting they seem to weld pretty nicely   a pretty good fit to the pedestal as well so we've already done the front drums of the  machine they actually weren't worn as bad as these   what a lot of customers or owners of compactors  don't understand is that the rear ones always   wear out a lot faster than the fronts being  that there is a lot of weight over the back   of the machine and it is doing the driving when  you start to see the compactor caps are wearing   out do a rotation so move the fronts to the  back and the backs to the front uh that just   sort of gives them a little bit more life  save a little bit more money so without any   further talking about it we're gonna get stuck  in to gouging these these caps off these drums [Music] [Music] what are these little rods that i use these are  a copper coated carbon rod the copper is on there   to create the circuit these are used for gouging  away material the carbon heats up the material   using the welders under a constant current  we run about 400 amps to burn a 10 mil carbon   there's an air jet runs down the side of the  torch that blows away the molten material   very quick and easy way to remove material  it is very loud the smoke is quite dangerous   that it produces considering it is carbon and  burning metals so respirators have to be worn   as i'm wearing my adflow protect yourself  as much as you can it is very very dangerous   they do get very hot and you will end up  very burnt if you don't take the proper precautions [Music] [Music] right guys so we finished gouging off all our caps  we've cleaned everything up ground everything up   um time to start fitting the new ones so all we've  got to do now is sit them on top of the pedestals   make sure they fit make sure they're  you know they're even front and back   make sure they're not hanging off the side  or cock-eyed these do fit really really well   so just make sure they're sitting nice  we'll stitch each end do that 60 times   and we'll be um ready to start welding them out  filler material we're going to use to stitch the   the new caps on it's a Fluxofil M10 that's a  metal cord wire very similar to our lincoln m71m   or your hobart 1100 the gas we're using is argo  shield heavy so that's an 80 argument the rest c02 we'll be running the machine at about 26 volts  and about five and a half meters of wire a minute   the reason i use the metal cord wires for  tacking or stitching on the caps is it's   a very fast so you're able to put in a lot of  amps and a lot of wire get a nice quick stitch   down to get around the other side and stitch  the other side down before it starts to move [Music] [Music] righto guys so we've finished tacking all the  new caps to the drums uh we've changed out our   wire to our xl525 it's a hobart product so this  hobart wire is a dual shield wire so it is flux   cord but it's also backed up by gas in this case  it's argo shield heavy with this particular wire   we'll run 27 volts and about 7 meters of wire  a minute i use hobart xl525 for welding caps   wear plates stuff like that because  it's it's a very very proven product um   doesn't let us down been using it  for years without any dramas 100  percent good wire for this sort of work it flexes it's  got great impact it lays nice it just it's proven [Music] [Music] [Music] [Music] yep how you going guys carl from cutting edge engineering [Laughter] nah it's curtis from cutting edge engineering  pedestal are we going to explain that bit   yeah right just keep going ah so we ah what was I up to  you were talking about what you're going to do   am I supposed to be [Laughter] yep right uh the main reason they they whip oh well [ __ ] i don't care um [ __ ] off um [ __ ] off you'll actually have  some i don't know what you call these [ __ ] i'm already getting [ __ ] frustrated well skip  that bit you want to talk about it well you   don't have to say every single thing you just said that but we'll start again then digging into my ass oh i farted it's going to go into my helmet [ __ ] hot wearing this [ __ ] thing are we doing it yeah all right uh the wire we're using is argo shield heavy the gas what did i say the wire oh uh that's [ __ ] Plovers and trains oh my god righto guys so we've uh we've switched out our  wires wait are we talking about wiring or that   tacking it together oh we just went through this  uh the amps we're going to run is about twenty uh wait it's uh so we'll be running about 27  volts and about let's start again um yep um it they it it nothing uh it's just good real good [Laughter] they don't sponsor us we don't get anything for this righto guys so the filler wire we're going to use to oh just  bit myself on the [ __ ] lip that was awesome okay very good so are you happy with that are you what is it [ __ ] dummy go go
