How to Install a Vehicle Lift (Part 2)

hi I’m Dan medela and today on Saturday mechanic’s we’re going to assemble our auto lift part two out of a series of three on how to buy and install your own lift before we get to putting anything together I think it makes sense to talk about the parts first we’ve got these two big upright so which we’ll get to in a little bit but let’s talk about the little pieces that are on the ground they’re kind of very important not kind of they are so here are these are our arms these are these are what reach out and grab the the car from underneath they are actually telescopic if we take these pads off and these extensions you can see that these extend out very important for getting good balance on the car so there’s four of those and they each they each grab a certain part of the car you’ll notice that they’re all the same length – that’s because this is an ASA this is a symmetrical lift it’s easy to balance a lot of a lot of different kinds of vehicles on this lift but it’s also a little bit more of a pain in the butt to get out of the car because when you pull in your door is almost always perfectly aligned with the upright on the lift with an asymmetrical lift your doors are almost always you can always open them easier like I said before we never know what comes into the PM shop so this is what we’re going to stick with a big heavy-duty baby so we’ve got those these are held on to the lift carriages these great big pins so you can see that these actually will push through right here and they’ll contact with this hole right in here there’s also a clip that retains these the other thing we’ve got our our wedge anchors each each upright has some of these wedge anchors they are super important that you get a good healthy size and a good grade bolt these are three quarter inch wedge anchors and they are good for thousands of pounds of pull the way these work is you drill hole in the concrete three-quarter inch and you put this nut on top of it and you put it in the hole you tap it down with a rubber mallet and then when you start to tighten it these little nubs on the on this wedge actually grab the sides of the concrete and as you tighten it this pulls and on this wedge it gets expanded on the wedge so it gets a really tight anchor on it so you get six of these per each each upright and and that’s a that’s what keeps them that’s what keeps them anchored to the ground so these are our our lift pads this is what contacts the bottom of the car some lifts have an ACME screw on the bottom that you can just screw it up to adjust the height this one’s really simple it just has pins of varying Heights you use no pin for really low cars and a really long pin for trucks or one or two limits you’ve got a lifted truck but that’s how this one works so we’re going to do the assembly on the ground now and I’ve brought in my buddy Russ who you’ve seen in the community episodes before who knows much more about these things than I do and we got a warm one here up in the Great Lakes State oh yeah I think we’re going to do a little bit of sweating today all right so basically we’re going to start by installing the crosspiece bridge cable bridge whatever you want to call it if you actually look at this you can see some pulleys here that’s because the carriage at the bottom actually has a cable system on either side that runs up and over to the other side of it and it and basically what happens is when when the lift goes up and down and make sure that the that the lift points the arms are the same level and that when if something should fail it automatically stops so we’re going to install this now first off and and go from there your side first yep yep got it alright so we’re just going to put these in finger-tight first I’ve got a couple of bolts here in there holes on the top of this thing I’m going to line got lock washers – it’s a little bit awkward but it’s not too bad all right get the bottom one next you get that no work on this side all right I think we might be a little bit off-kilter mine might be behind yours a touch I think I’m good okay so we’re gonna just finger tighten these make sure you start them with hand by hand

Chris because the last thing you want to do at this point is cross thread something that’s always a bad day and don’t tighten anything till all four are in place just still righty tighty lefty loosey as far as I know all right the heat maybe they use chrysler lug nuts I’m gonna wrong side left-handed lugs could be helpful all right you good nope gotta kick this out just a little bit he’s got a couple degrees yeah no I think yeah here I think the base there has to come out are towards me you got it can you bring it can you bring it this way can you bring it to my right please touch okay doing this because the uprights are not perfectly parallel and there’s very little room in here to put the fasteners yet wiggle yeah okay and then we get these finger tight once they’re all in place you get them finger tight and then when we tighten them it’ll draw them all together do some big boy tighten it tighten the first when all of them are our finger tight he’s holding the inner one with a wrench yet we’ll come back here with the cork wrench and make sure we get them to the correct step all right so I’ve got the installation manual on my tablet here because I’m late a modern technological guy no lazy and I don’t have a printer torque spec for this top place 45 foot pounds excellent so let’s put that on so I’ll use this beam type torque wrench and remembering that I have to hold it in the middle like get it off to the side or the side like that it’s incorrect I want to get it right off this pivot the upper let’s see upper all right all right next one ready there’s 45 all right next up you’re looking hot Russ thanks buddy I remember how we remember that yeah well you know what are friends for right well you’re gonna want to use this thing good point okay so next part after we’ve got this cross piece why wouldn’t any safety cables any yellow doesn’t the hydraulic doesn’t hydraulics lift it on its own yeah yes however there are two hydraulic cylinders in this machine one for each side and if they already get out of sync as you’re lifting the car then the car goes up sideways and eventually falls off which is a bad day for everybody so what these things do is they balance out the the carriages to make sure that they go up simultaneously it’s really a tremendous safety feature okay how are we going to turn this 90 degree well there’s a there’s a pulley in here that’s got a pin in it we’re going to pull that whole thing out and run these up the column over the top down the other column and tie it into the other carriage on the other side right you pull that out and I’ll feed this through okay all right here’s that pulley make sure you can get that in there okay so what’s going to happen as I understand what’s going to happen is this cable is going to be on that post that’s inside there and that’ll turn it 90 degrees right okay it’s all that I’ll give you select okay you got plenty of slack washer then the safety clip yep what do you say when you drop one of those drop one what nothing nothing anymore all right all right forget it nope we’re not behind it and there we’re all right same thing on the other side behind the pin yep okay put the pulley in there it’s gonna give you some nuts

as much life as I can all right and pinned all right you show me show me the other end of that please all right so this will go down this will go down to this lifting arm on this side we’ll slide that through we’ll put on this nut which will be the lot which will be the adjusting nut and this will be the safety lock nut that will jam those two together and when we need to adjust it later we’ll just loosen the lock nut adjust it get them both balanced nicely take a note to that there’s a square end on this that’s what you use with your your box end wrench to to do the other end of the adjustment otherwise you’re just going to twist and twist until this point hey then we brought this other cable over it’s twin to the one we showed that we strung over the pulley denouncing that one’s already bolted in that one bolted in so now we’re going to connect this to this lift this side lift which is where the first cable came from God and now this lift has actually got a service windows cut into this specifically so that you can adjust it you pull this off and it gives you access to the the lock nut and the adjustment nut here for the the cables and we’ll probably check that at least every six months you should check you should check the adjustment for them yeah and what we’re going to do now is really just throw it on because it does make sense to get an adjustment since nothing is tensioned we’re not going to adjust it until it’s all right the last thing we’ll do before we lift a vehicle test it up is adjust attention hmm all right so let’s uh let’s throw this thing on okay what can I do it’s important I think yeah I just hold it on there and I’ll work from this side we’re tightening the adjustment nut at this point and next we’re going to throw the lock nut on because not because we need to lock anything down but because otherwise it could probably get lost yes then we’ll lose it it’ll get the other thing we get the other thing tonight that’s nice here is if we give a little bit of tension to this it will keep the cables on the pulleys that we that we have so all right we’ll get that and we got a little bit of it we got a little bit of movement to do but we’ll take care of that later on all right this is the main safety device for this lift anytime you’re working on a lift you’re not familiar with check these first if these are not functional don’t work under it so it’s very critical that you get this thing set up right on your own lift it’s actually not too bad to install either no so what you do is you slide it in before you get going and this big pin here we slide this spring over the top and this keeps it fully engaged at all times you’ll see how that works in just a second so we’ll slide this up from the bottom okay so that spring pressure forces it in towards the the lifting arm right on both sides okay so that’s why we have the spring alright so then if we can tighten beastman my way to get this thing over the top I don’t know that’s not good anywhere wrong lick the book and we as always put the safety pin on so as you can see this would lock in anytime that the carriage comes up so what we’ll do now is we’ll actually start on the other side with this cable run it all the way over and when we get to this side cable will come through along the pulley there’s actually a hole I could find it in this bolt I don’t know if I’ll be able to find it with this angle it’s a little bit like threading a needle I’m not going to bother it right now but you then pitch this down and it stays in place it’s a lot like threading a needle and then this pulley here will allow that to turn 90 degrees and then I’m out a hobby and then a 90 just like were the big cables went correct and another 90 at the other top corner and then down to its brother or sister device max on the other side but that’s I doesn’t have a handle no no hand no need is only one good point so there salamander man a warm enough for you today yeah I think I’m sweating enough yeah yeah yeah you bet we need to definitely need a shower after this so when we’ve got that in place the next thing we’ll move to is the hydraulics all right next hydraulics this thing has got a single-channel hydraulic system that divides the hydraulic pressure between two cylinders because of

Pascal’s law the pressures in a closed system the pressure is the same everywhere so we just have to pump fluid into one hose connects to both cylinders and then it they’ll rise at the same pressure the thing is we’re not going to be able to show you hooking up the bottom side of that hose because it’s pretty well buried in the in the base of this thing it’s really tighten there and you really can’t see anything it’s a it’s a 90 degree elbow and you hook your hydraulic hose to that everything’s got to be good and tight I think we’ve got an illustration for that and then you hook that hose up and run it up to the top so with this kind of connection if if you happen to see a leak there’s really nothing to do about it it’s maybe the threads been stripped or something like that what you got to do is replace the hole at least the whole end and that can be done in any hydraulic shop at every town has yep and and I actually have had that done because I have stripped those ends out yeah but we’ll we will make this connection once and it’ll probably never be touched again it should be done yeah so we’ll run this one now there’s little retainers inside the upper upright post here and we’ll run them through those make sure not to get this thing wrapped up in any of the cables that you’ve already run and you have to do it again I’m just speaking of the way there there we go up over the bridge yep and there’s a bar over here and of course all these lifts are different but there’s a bar on this one that you run these cables over so that doesn’t bind up or get pinched pinched and rubbing rubbing on it it’d be like rubbing on your garden hose eventually the water would leak out so you don’t ever want to have any rub rub points on a hydraulic hose and now what we’ll do we’ll join those two cables with the with a t-junction and run the main control line up around again and hook it all together so this is the hydraulic line that runs to the actual pump and then it will run to a t-junction there and distribute but we got to run this down since there’s an elbow on that end it’s easier for us to run it from the top down I’m going to run it down just like the other way step backwards remember to keep these in that retainer as well are you on the top or the bottom I’m on the bottom okay okay now this hole right here where my fingers are sticking through this is where I have to pull it through so that it can access the pump correct it will actually turn the corner to and that is about right okay this is a tee fitting it’s because it looks just like a tee you don’t say and this one is an elbow okay which looks like my elbow okay so this fitting here in the center is going to come from our hydraulic pump and these two are the ones we ran earlier that are going to Dakota each cylinder so we’ll loosely fit like we always do when we have multiple connections we’ll loosely fit these when I want to hold you got you that better hand äj– okay well loosely fit those all right and then this I think what we should do now is tighten those and then we all have time we can put that on there all right so we need an 11 millimeter here I’ll grab that okay and you don’t because you have a a wedge fitting there it’s very it doesn’t take a lot of a lot of tightening roughly about 20 foot pounds like about like a spark plug really you know that how you tighten a spark plug and and that will be enough to seal that if you have any leakage there if you have any leakage there we could always go back and snug that up but again like you said earlier we don’t need any teflon tape any pipe dope or anything this is a mechanical connection right and now we’ll fit this one as well fingers start these as always the last thing you want at this point is to strip anything out on here then did you notice how this nut here and these two here have a little slot in them that tells us that it’s metric it’s a metric fitting how about that now we’ve got these just like that and like Ross said there may be leakage they might not be tight enough and the only time we’re going to know that is later on when we try the system out so after we test it we’ll climb a ladder inspect everything if we see any leaks where we’re in need of a little bit of a more tightening so just to snug it up in metal and that’ll make this work yep and this will lay flat on the surface when we’re done and and these cables will all pass right over it so with that we’re a I think we’re both sweated out actually yeah we also happen to be done so if you have any questions about what you’ve seen today leave them in the comments section below and stay tuned for part three where we raise this baby up hook it up

and try it out you
