I recently bought a Harley Sportster and decided it was time to change the engine oil. As a newbie, I mistakenly drained the transmission oil instead of the engine oil because I wasn't sure which plug to use. The oil container still looked full, and I was freaking out about how to replace or refill the transmission oil. I searched everywhere on UA-cam but couldn't find a helpful video, until today. Finally, I found a video that featured the exact model of Sportster I own. It was such a relief! Thank you for the clear and precise explanation-it saved my day!
If ya lay the bike on its side you can fill the oil filter up and screw it on and that way you have no start=up without oiling the crankshaft!@@KnobleMoto
Holy cow! You made it look sooo easy! I am a noob about doing my own oil changes and such (I am trying to learn as much as I can about fixing motorcycles) but this tutorial was so easy to understand, your camera angles were great and your explanations were awesome!

I'm doing an oil and filter change on my 87 sportster before the summer starts - its amazing how little the design has changed although the oil line is much easier on the 87.
Thank you brother for a Very informative video. Never doing it before but knowing changing the oil is not hard watching your video. Definitely built up the confidence to change it myself. Thank you safe out there.
Also want to agree with others on the quality and great help from the video, many thanks. Enjoyed your style in this and the primary chain vid too. Not new info for me, but wanted to like, comment and sub to help bump your channel. Good stuff. 👊
The Harley Service manual for my '03 Sportster says that the oil level for the primary should be at the bottom of the clutch spring, which is the round device you see when you look inside the clutch cover. Overfilling can cause some shifting problems. Before you install the new oil filter, you may put about 4 oz of new oil in there and let it soak into the filter. This will help build oil pressure sooner when you start the motor.
Its not the spring it is clutch basket gear that you are looking at.The fluid is suppose to be barely touching the teeth on that gear.The service manual has a picture showing that.
@@tylerhubbell6410 check out the text following the picture. Step 9: “verify that the lubricant is even with the bottom of the clutch diaphragm spring”.
The allen equivalent to the torque screws are 1/2-20 x 5/8. He said x3/4 but those were longer than the oem ones, at least on my 08 xl1200c. I had to change a couple of stripped torque screws.
I feel like they are easily stripped out, and I feel like I can never get the bit in there far enough to get a good bite on it. Allen’s always seemed like a solid fit to me. (Plus it adds a little subtle humor to the video 😂)
When i used to change my own oil, i would clean the drain plug area with a rag and compressed air. Also, the Sportster has its own formulated primary oil. Using a thicker gear oil will run hotter and will hold heat. A lot of people overfill the oil tank because many manuls state 3.5 qts. Also you didn't burp the line . .my 2 cents, which you probably didn't wa b .
Couple years, but growing up my grandmother always bought me dirt bike’s every couple years so getting on it was a piece of cake. I got it last week. Yesterday I rode a wheelie on it for almost 2 miles
Amsoil recommends using V-Twin 20W-50 oil for both the engine and transmission. 75W-140 is thicker and will retain more operating heat so the benefit of the transmission running quieter is canceled out by more transmission wear because of the increase in heat.
Excellent article and film, many thanks. Is it possible to list the tools and the numbers of the different keys: or range, Alan key, is the star flat or spherical and what is its number, etc., thank you very much David
Make Shure u put in one quart in the primary to little u burn out the thro out bearing to much your clutch will slip so one quart And make Shure you put your screws on the primary cover in the same holes they came out l once put in screws thinking they were all the same size mix up putting them in the primary cover some were shorter then the other and I lost my fluid well driving because of a screw in the wrong hole once I found out I put the screws in the right holes On the primary cover replace spring good idea it fits inside your primary cover so when you put it back on hold pressure on cover and tighten your screws in the right hole for the long screws and right hole for your short screws
Hey thank you for youre video. Just wanted to know, if youre bike is on the side stand to fill up the oil. i heard a few that you have to measure the oil when its on the side stand.
Upright is best but it doesn’t really matter. If it’s on the side stand, once the oil is drained out of the tank, stand it up straight for a few seconds to make sure you get any remaining oil out.
I recently drained the primary by mistake, unfortunately the gasket fell off I cannot get it to stay on is there a trick, or do I need a new one? It looks okay and I see they're a little tiny hook like things to drop it in but it's not working I have a 2008 883
Good video man. Ive changed my oil a ton but never done trans by myself.... looks way easier than i thought.... and only 1 quart? hmmm.... I wonder if my 99 sporty is the same... gunna find out... Thanks again man good video.
@@KnobleMoto I appreciate your time and response. I've been using 20/50 in the primary same oil as I use in the engine but the clutch just doesn't seem right and it seems louder in the primary with the 20/50. I'm gonna try the gear oil and see how it goes..
@@tayloralexis1504 I think you will find it all works better with gear oil. Just make sure it is either specifically for a Hd primary or is listed as “for limited slip differentials”. That means it has friction modifier in there to make a wet clutch work smoothly.

level or almost level. If it's on the side stand the oil will come out the clutch cover. But if you refill it at the inspection port, and the clutch cover is on, the bike doesn't have to be upright. Just make sure you put the right amount in.
On the sportster, prefilling the filter doesn’t work because you have to turn the filter on its side to install it. Some filters have it on the label that they do not require it. And if the engine is running on a regular basis, the air in the system will bleed out pretty quickly, so it’s not as necessary as some people make it out to be.
Any symptoms I should watch out in case it's overfilled? My tech guy says it's supposed to be around 1,2l (1.2 quarts). Not sure I should be worried but I'm gonna do this service soon, so trying to learn as much as I can
@@KnobleMoto you only fill it halfway and then bring the filter close and top it and screw it right in quick and barely any spills … been doing it that way for years …
Use a puppy pee pad instead of using the aluminum foil. Also you used gear oil in primary and not 20-50 synthetic oil. Have you had any problems using gear oil?
@@KnobleMoto Synthetic is more likely to make your clutch slip and doesn’t preform as well with the extra heat from a Harley. You want thick oil for your primary, regular 10W-50 or 75W-140
@@adamupusa I have personally put 150k on an assortment of bikes. All with synthetic, and all had properly working clutches. Actually on my channel you can see me measure some dyna clutch plates with 50k on them, and there was virtually no wear. Synthetic will last notably longer, and it is a better lubricant. But it won’t make you clutch slip. Though to ensure you have a smooth clutch operator, you should get primary oil with “friction modifier”. If you don’t he clutch can be grabby. But it definitely won’t slip. Now you are correct about the weights of gear oil to run in there.
@@KnobleMoto It may depend on how hard you ride your bikes and if you’re doing stunts or riding fast all the time. I’m sure if your just cruising then you’d be fine with synthetic but all my guys don’t use synthetic. You’re welcome to call any Harley dealership and talk to someone in service, they should all confirm that they don’t use synthetic as well.
@@adamupusa I’m sorry but that isn’t accurate. If any tech told you that, they were being sarcastic or making fun of you. Besides the motorcycle racing and tuning world, I worked in heavy steel fabrication and NASA for many years. Unless cost is a concern, there is no situation where you would use conventional oil over synthetic. When you build an engine, you run conventional oil. That is because synthetic is such a great lubricant that the engine will not properly break in. Synthetic is the reason cars last 300,000 miles today. At NASA we didn’t put conventional oil on anything that flew. We even used synthetic coolant in the CNCs. If it’s worth any money, you should put synthetic into it.
WRONG at time 0:43 he acknowledges the Primary and engine are the same type oil on this model sportster, then he proceeds to put 75-90 gear oil in it at time 8:58. . the wrong oil. YES many people put gear oil in and it is absolutely wrong to do on these model transfer cases. The reason is this model tranny needs very thin oil because it generates a lot of heat on the clutch pack, that the thinner oil carries away when it splashes the clutch. Thinner oil holds/stores less heat into it. It is not a good heat capacitor that can store tons of heat, this means it must dissipate the heat fast or it will be overwhelmed by heat. And it does dissipate the heat very fast it collects by conduction and even convection methods in the engine. . Much faster than gear oil. , Also the tolerances are tighter on all the rotating assembly such that thick gear oil won't penetrate properly into the moving journals, this causes accelerated wear on all journals. You absolutely do NOT want to put any type of Fiction modifier such as for limited slips in this tranny either. These clutch packs are designed to a specific viscosity of oil and thickness that the 20-40 weight delivers. the clutch packs are designed to slip a specific amount with a specific oil between them. . that a friction modifier will change. IF the clutch grabs to hard the non-case hardened teeth on gears will break off. This is why the clutch is designed to slip a specific amount. to reduce instantaneous shock on gear teeth that will snap them otf. The clutch pack is compressed on the oil and the specific density of the oil being changed by any type of friction compensator will damage the clutch pack because it will either expand the clutch plate interface and slip too much between plates or contract it and grab too hard. the two working together will cause clutch chatter when gear is released every time, bouncing of plates. Both are bad, Im not a shade tree mechanic. Im a post graduate engineer and it is all fact
Oh you’re a post grad engineer all right 😂. I was a Millwright at NASA for 6 years, and I met a lot of you guys. You’re overthinking this. You need sticky oil for a transmission that goes 0-100-0 quickly and repeatedly. 20/50 doesn’t have that stickiness. The friction modifier isn’t going to do anything to the clutch basket or gears compared to the debris from the primary chain and the clutch particles. Also the information I am sharing here isn’t new, it’s pretty standard across the motorcycle community, so I have millions of miles of real world usage on my side.
@@KnobleMoto sticky OIL? lol, Is that like sticky notes or sticky rice. LOL. FYI Its called high surface tension. LOL. for your information you absolutely do not want oil dragging on the clutch, that's is one of the reasons the oil level in the primary must barely touch the clutch pack. Everything I said is fact, It is ok ALL you know is how to change parts. You should never challenge greater wisdom than your own. But you're trying to go into the mechanical, thermal dynamic and fluid dynamics is laughable. You should just Fix that broken video and get rid of the shade tree mechanic concepts you have in your head.

Friendly advice, don’t use synthetic for your primary. Please update that for your video if you can.
Why conventional vs synthetic
@@KnobleMoto Synthetic is more likely to make your clutch slip and doesn’t preform as well with the extra heat from a Harley. You want thick oil for your primary, regular 10W-50 or 75W-140
@@adamupusa I have personally put 150k on an assortment of bikes. All with synthetic, and all had properly working clutches. Actually on my channel you can see me measure some dyna clutch plates with 50k on them, and there was virtually no wear.
Synthetic will last notably longer, and it is a better lubricant. But it won’t make you clutch slip. Though to ensure you have a smooth clutch operator, you should get primary oil with “friction modifier”. If you don’t he clutch can be grabby. But it definitely won’t slip.
Now you are correct about the weights of gear oil to run in there.
@@KnobleMoto It may depend on how hard you ride your bikes and if you’re doing stunts or riding fast all the time. I’m sure if your just cruising then you’d be fine with synthetic but all my guys don’t use synthetic. You’re welcome to call any Harley dealership and talk to someone in service, they should all confirm that they don’t use synthetic as well.
@@adamupusa I’m sorry but that isn’t accurate. If any tech told you that, they were being sarcastic or making fun of you. Besides the motorcycle racing and tuning world, I worked in heavy steel fabrication and NASA for many years. Unless cost is a concern, there is no situation where you would use conventional oil over synthetic. When you build an engine, you run conventional oil. That is because synthetic is such a great lubricant that the engine will not properly break in. Synthetic is the reason cars last 300,000 miles today. At NASA we didn’t put conventional oil on anything that flew. We even used synthetic coolant in the CNCs.
If it’s worth any money, you should put synthetic into it.
What gear oil brand did you use
Mobil One usually.
@@KnobleMoto alright cool thanks for the info
@@jayydawg3228 you’re welcome
@KnobleMoto was is it 75W-140?
@@diegoavila4379 yes it was
Go the ss button head 👍👍👍💯💯💯🇦🇺🇦🇺
That a solid route to go👍👍👍
WRONG at time 0:43 he acknowledges the Primary and engine are the same type oil on this model sportster, then he proceeds to put 75-90 gear oil in it at time 8:58. . the wrong oil. YES many people put gear oil in and it is absolutely wrong to do on these model transfer cases. The reason is this model tranny needs very thin oil because it generates a lot of heat on the clutch pack, that the thinner oil carries away when it splashes the clutch. Thinner oil holds/stores less heat into it. It is not a good heat capacitor that can store tons of heat, this means it must dissipate the heat fast or it will be overwhelmed by heat. And it does dissipate the heat very fast it collects by conduction and even convection methods in the engine. . Much faster than gear oil. , Also the tolerances are tighter on all the rotating assembly such that thick gear oil won't penetrate properly into the moving journals, this causes accelerated wear on all journals. You absolutely do NOT want to put any type of Fiction modifier such as for limited slips in this tranny either. These clutch packs are designed to a specific viscosity of oil and thickness that the 20-40 weight delivers. the clutch packs are designed to slip a specific amount with a specific oil between them. . that a friction modifier will change. IF the clutch grabs to hard the non-case hardened teeth on gears will break off. This is why the clutch is designed to slip a specific amount. to reduce instantaneous shock on gear teeth that will snap them otf. The clutch pack is compressed on the oil and the specific density of the oil being changed by any type of friction compensator will damage the clutch pack because it will either expand the clutch plate interface and slip too much between plates or contract it and grab too hard. the two working together will cause clutch chatter when gear is released every time, bouncing of plates. Both are bad, Im not a shade tree mechanic. Im a post graduate engineer and it is all fact
Oh you’re a post grad engineer all right 😂. I was a Millwright at NASA for 6 years, and I met a lot of you guys. You’re overthinking this.
You need sticky oil for a transmission that goes 0-100-0 quickly and repeatedly. 20/50 doesn’t have that stickiness.
The friction modifier isn’t going to do anything to the clutch basket or gears compared to the debris from the primary chain and the clutch particles.
Also the information I am sharing here isn’t new, it’s pretty standard across the motorcycle community, so I have millions of miles of real world usage on my side.
@@KnobleMoto sticky OIL? lol, Is that like sticky notes or sticky rice. LOL. FYI Its called high surface tension. LOL. for your information you absolutely do not want oil dragging on the clutch, that's is one of the reasons the oil level in the primary must barely touch the clutch pack. Everything I said is fact, It is ok ALL you know is how to change parts. You should never challenge greater wisdom than your own. But you're trying to go into the mechanical, thermal dynamic and fluid dynamics is laughable. You should just Fix that broken video and get rid of the shade tree mechanic concepts you have in your head.
@josephkaminski1857 did you just graduate in the past few years? What your opinion on using whale blubber in the transmission?
@@KnobleMoto I have smarter pets than you. You are nothing but a disruptor to humanity spreading nonsense and causing people harm who are unfortunate enough to believe fools like you.

😂😂😂😂😂😂😂I was waiting for someone to notice that.
Stop calling a 2012 sportster a Iron head stop trying to make them sound special it's a evo motor lol
When did I call it an Ironhead?
Sorry you only called it a iron sporster
@@anthonylippa7346 no worries. ❤️
