Motorcycle Oil Tank Install How-To on a Hardtail Triumph Chopper

0 Comments 12:28 pm

hey this is Tyler with lowbrow customs today we're gonna show you how to mount an oil tank onto this Triumph bobber [Music] lowbrow customs has custom oil tanks for your triumph or British motorcycle as well as Harley Davidsons you can check out our oil tank comparison video if you want to see more information on our oil tanks vs.

Other ones that are out there and inform yourself on what oil tank you need for your build this oil tank made specifically for triumph because it has the proper plumbing and you can get more information from that video I refer to but there is the proper return tube with the feed for up to the rocker boxes on this triumph and this bung is threaded properly for the stock style oil feed fitting that has a filter screen that fits in there and that's where the oil feeds to your motor any case this tank is made specifically for these bikes in addition to the oil tank the mounting kit that we make specifically for this makes installation a complete breeze we've got two brackets here that are rubber mounted and they're designed specifically for 1963 to 70 triumph frames but all of our oil tanks have the same center-to-center mounting points and bung locations so these brackets could really be used on any of our oil types I'm gonna go ahead and put these brackets on the oil tank and show you how it fits really nice into position [Music] one thing you might notice about these brackets is that they're rubber mounted so this is a quarter-inch mild steel extremely beefy you never want your oil tank mounts breaking while you're riding have your oil tank come loose or worse yet actually snap off of your bike and we designed these mounts to make installation a breeze and ensure that won't happen there are rubber grommets in here and then we have these custom machined alloy top hats that slip in there and so when you bolt it in place with this five sixteenths 18 threaded hardware it gives a little bit of wiggle to these brackets now what that means is vibration from your bike or bumps in the road aren't going to transfer director oil tank potentially causing failures at any of the welds or at the mounting points it's just gonna give that tiny bit of give that allows you to to ride it really hard and simply just not worry about any of this breaking we've got these mounting brackets coped specifically for this vertical seat post and as I slip it in here you can see that it's a perfect fit it leaves about a quarter inch between the oil tank and the seat post it allows you to really it install this at any height you want I tend to like to install these as high vertically as possible keeping in mind it's a center fill cap and you do want to make sure whatever seat you're mounting you know doesn't interfere with that cap but also you want to watch when you're mocking this up that you have the chain on your motorcycle because you want to have plenty of clearance between your chain and the oil tank because under load and more under deceleration when you let off the throttle your chain will actually move quite a bit and waver and you don't want that slapping your oil tank because it will end up you know eating a groove in there and then you have a whole nother problem to deal with so to prepare for installing these these brackets what I need to do is go ahead and strip a little bit of this paint powder coat whatever this is on here off of the seat post tube and I'm gonna go ahead and get ready to tack weld this into position so I don't waste too much time stripping a bunch of paint that's not in the way I'm gonna go ahead and hold this in position and just this is a basically little grease pen I'm just gonna make a mark where to clear the paint the other thing you can do is take a scribe or anything sharp and even just make a little scratch some sort of reference and then before I go ahead and strip that paint I'm gonna cover it up the engine with the sheet so Todd doesn't yell at me for getting you know black dust all over his newly rebuilt engine or inside of it it's a really good use for some old sheets from Goodwill or in this case my grandma's house okay so what I'm using here is just a little angle a little die grinder hooked up to my air compressor we've got some air plumbed here in the garage and these little quick change basically it's a scotch-brite pad there are different roughnesses available these are really handy and so instead of you know you could use like a flap this kind of grind or something but I'm gonna go ahead and see if this will work because I don't want to go taking material steel off of this at all giving a like a lumpy finish or anything like that all I want to do is strip the paint off there so you know I'll give this a try and see how this works [Music] [Music] [Music] [Music] all right that's scotch-brite pad works quite well to get through maybe this is spray-paint on top of what's bar like the factory epoxy so it's pretty pretty thick layers as you can see what I'm going to do is just go ahead before I consider that part done I'm gonna just hold the tank roughly in position again that's pretty good I essentially just want to make sure that when I'm welding that the paint's you know if it's too close to the weld area it starts smoking and it just stinks and I don't really want to breathe that in it's a little hard with this hardtail bolt in place with that grinder to get into this edge here I'll take a little piece of Emery paper real quick and sand that up and get that last little bits off that are in the way and it should be good to go and ready to weld this is Emery paper you can find it at any hardware store like the plumbing section I like it because it comes in rolls and it's inexpensive and this is 120 grit so this works really well you screw up a piece off as needed I always have several rolls around and you can hold it and easily sand to be hit a couple of these thicker stubborn spots that I couldn't quite get at with the die grinder I was using we'll go ahead and hold this up again double check here alright looks like I'm going to be ready to align this and tack weld it in position so I'm gonna go ahead and blow the dust off remove the sheet wipe these areas down clean the bracket and get ready to weld so a little bit more weld prep since I'm gonna be TIG welding this these brackets are clean but you never know if there's a little bit of you know oil on them or anything else I'm gonna go ahead again with my little die grinder and a worn out scotch brite pad I was gonna go ahead and hit kind of the edges and the COPE where I'm gonna be welding and then I'll go ahead and wipe this down and and weld it up this helps keep me from getting frustrated by pulling impurities into the weld it's a little bit of prep time goes a long way actually a good amount of prep time can save you gobs of time when welding because once you have an issue pull some oil into a weld or something yell get pinholes it looks bad it's frustrating so proper preparation prevents piss-poor performance [Applause] [Music] [Applause] [Music] all right now everything is prepped and clean and ready to tack weld one thing I would suggest after a kind of a lining getting some tack welds in place my goal is gonna be to tack welds on each bracket I'm really gonna then look at it from different angles ensure that it's not slightly angled wrong or not too high not too low whatever because it's a lot easier to break some tack welds and just restart as far as positioning as opposed to lie completely welding everything up standing back happy with your work in realizing that it's crooked if you like me that will drive you nuts and you will be cutting it off and redoing it so I'm gonna go ahead and get my gloves on and get this done in my case here I'm using a lincoln electric TIG welder you can also MIG weld this is all mild steel stick well do whatever you want so when it comes to positioning you can clamp or use magnets or you can do if you're comfortable with based on just how I'm used to doing things and also because it's just fast and I find it easy I'm just gonna visually align everything and check it as my friend Greg once said if you you stare at it long enough and you can't tell if something's crooked then it's not it's good enough so what I'm going to do here I've got the bracket against the seat post I'm gonna go ahead and put all the way up till it touches the frame rails you absolutely do not want to mount it so the tank is touching the frame rails I'm gonna drop it down so I've got an eighth inch or two hundred dollars but wean the the frame rail and the tank itself you'll get a tiny bit of movement and the oil tank from the rubber mounts but but not very much and probably like 20 thousands or something not not very much to worry about it all so what I'm doing is I'm gonna visually eyeball the line of the tank and make sure that it's parallel to this seat post tube and before I go ahead and get too far into welding you know I'm gonna like I said tack weld eyeball it from all sides and if it's not right on I'll just go ahead and break those tack welds and do it I'm gonna go ahead and get everything set up so once it's in position I can use my foot pedal here and get at least one good fusion tack and then grab my fill rod and get a heavier attack on there on the top bracket [Music] [Music] [Music] okay so I've got the first tack and I noticed as I I ball from above I'm actually looking also to this battery box as well as this crossmember just for a visual and I can see that the oil tanks slightly this way but when I push on this bracket it straightens out perfectly so if you're familiar with welding you know throwing a tack off to one side it's gonna go ahead and pull the material that way and you want to compensate for that so again it's a good reason to take your time you know you've gotten this far setting up last thing I do is rush right at the end and have something minor crooked so I'm basically gonna put that pressure on get another tack in there eyeball it again grab my filler rod and put a couple more tacks on that upper bracket and then move to the lower one I could actually feel the tank pull this way does that tack cooled and it looks spot-on but I'm gonna put my torch down and take a better look at it just make sure I'm not wrong and actually there's a good reason so as a good reason I stopped because it actually I've got okay clearance on this side but it tightened up as the bracket moved over to this side right here but what I'm gonna do is take a look it looks like my brackets actually lifted up slightly and again that's from it pulling from welding at the top here it's going to want to bring that bracket up so I'm going to take a moment to lightly tap down on this to get this lower bracket the seat totally and go ahead and get some tacks along the bottom of this top bracket and that'll hold it in place sometimes this will just break the attacks right off which there's no big deal can be a little annoying moved it a little bit and again I'm looking also to make sure this brackets perpendicular to the seat post tube everything looks good I have sufficient clearance from the oil tank to the frame now so I'm going to go ahead and throw another little tack well to the the corner of that top racket and then go ahead hold the lower bracket in place attack while that and be ready to finish weld cool time to check the bottom bracket all right after tack welding I went ahead with my fill rod got a little bead on both sides of upper and lower bracket just so I was confident they wouldn't move because now I'm going to go ahead and unbolt the oil tank and finish weld the bracket one other thing I might mention is before finish welding you want to go ahead and remove your top hat spacers and the rubber grommets because if you don't you're just going to melt them and be calling us for new ones okay hardware spacers grommets all out of the way now we've got a nice clear shot more or less and finish weld this up and be done [Music] [Music] [Music] [Music] [Music] all right welding is all done that went pretty fast we'd let this cool down enough we'll go ahead and I'm gonna put the hardware in bolt the tank in place check Fitness okay got that all in it's a bit of a bit of a snug fit with the rubbers in there when this was going together for final assembly say that oil tanks played it or painting it or powder coated I'll take it a little wd-40 or something on your finger and just wipe it on the rubber grommets and it lets it just slide into place and obviously I'd be a little more careful so I don't knock this into the paint on the frame or anything but so far we are looking perfect [Music] and there you have it one securely and beautifully mounted oil tank it took us not too long especially considering I also had to talk to you guys while I did it and we're set everything up to film it and just one more element of this bike done and we'll wrap up some more fabrication on it and have it painted plated ready to go riding on the road this spring enjoy if you enjoyed this video and you want to see more like it plus event coverage and all kinds of other motorcycle goodness
