Question about 2002 Harley Davidson FLHTCUI Electra Glide Ultra Classic

1 Answer

I have a 2002 ultra classic. I am using Moble v-twin 20W50 oil in the engine. I was told I could also run the same oil in the trans and in the primary. What I am asking, for one thing is this true and if not, what oil can I use in the trans and in the primary? It takes me 1 1/2 hours to get to the harley dealer so i am looking for other oil options if there is any.

Use your 20W50 for crank. Use 80/90 Gear oil for tranny and something like 15w40 or 10w30 for the primary.

SOURCE: engine oil plug

Another way to locate it, is with the bike on the kickstand, look underneath of it from the right (brake) side. The oil drain plug is on the front of the square looking pan under, and to the rear of the engine. The oil drain is the plug on the front of that pan, on the left (shifter) side of the bike. The trans drain is on that same square looking pan, but towards the right side, and faces down. It screws in and out vertically, whereas the oil drain is horizontal

SOURCE: removing harley davidson ultra classic gas tank

Drain the fuel either by siphening or removing the cross over tube at the front of the tank and letting it drain that way or just block off those cross over lines and leave the fule in the tank for removal.

0) remove seat
1) drain fuel
2) undo cross over line (bottom front of gas tank.
3) shut off pet **** and remove fuel line from pet ****.
4)there should only be 2 bolts holding the tank on, one at the top front of the tank and one at the back of the tank.

All in all a pretty easy (but possibloy messy) job.

SOURCE: for a 2001 Harley Ultra Classic where is the oil

The oil tank is on the bottom of the transmission. There are two drain plugs, one for the engine oil and one for transmission lube. The engine oil drain is the one closest to the left front of the oil tank. The drain that is more in the center is the transmission drain.

SOURCE: oil blowing out through air-filter,rough

Your '98 Evo motor is what they call a "head breater" engine. This means that the crankcase ventilation is at the upper end of the heads rather than way down at the lower end of the engine like it used to be. They the first year for the "head breaters" was 1994.

Now, At the top of the heads where the rocker boxes are, there are three pieces. The lower rocker plate with the rocker arms in it, the middle piece and the upper cover. If you take the four bolts out, you'll see an umbrella valve in the middle piece of the rocker boxes. This valve is a replacable rubber piece. Over time and many times of heating up and cooling down, they can get brittle and allow a lot of blowby resulting in oil in your air filter element.

Now there is another part in the cam chest that has a lot of effect on the operation of the crankcase breather system on your bike. This part is called the "breather gear" and is located down in the cam chest to the rear of the camshaft. In you bike, the part is made of plastic if it's the original part. I have seen the teeth break off of the drive gear and the breather gear stop turning. This will screw up the "breathing cycle" on your engine and cause it to "blow oil". Usually, the oil pump locks up when this happens due to the plastic teeth getting in the oil pump but not always. If this eventually turns out to be your problem, have the mechanic or yourself install one of the new S&S reed valve type breather gear replacements. They don't turn at all and work absolutely great. The part is about a hundred dollars but it's well worth it. Solves the old broken breather gear problem that has plauged the Evo engine it's entire life.

There are no "screens" in the Evo engine other than the "tappet oil screen". Just in front of the oil pump is a screw plug that is in the engine cases itself. If you remove this plug, there is a small spring and cone shaped screen that filters the oil prior to it going to your tappets. This should be cleaned every other oil change but it has nothing to do with the oil in your breather.

Now some riders will tell you that if you allow your Harley to sit for any length of time that it will "oil sump" with you. By this, they mean that oil will seep past the check ball in your oil pump and pool up in your crankcase. When you start the engine up, oil will be blown into your oil filter. Not true on your Ultra. The bikes that will oil sump are the Sportsters, Softails, Shovelheads, or any bike that the oil tank is higher than the oil pump on the frame. On your Ultra, the oil tank is on the bottom of the transmission. Your bike will not "oil sump" unless you have a sheared key in your oil pump or the oil has somehow learned how climb. You oil tank is below your pump in other words and oil does not flow uphill.

What is the recomended oil for a 1997 harley davidson heritage softail classic


Harley recommends you use their 20w50 or Syn 3 (synthetic) oil. If you use Syn 3, you can also use it in the trans and primary. If you use conventional oil, Harley's Formula Plus goes in the trans and primary. Truth be told, any good high quality motorcycle oil (Amsoil, etc) made for air cooled engines will work in the crankcase.

Engine oil light flickers


First, are you running the correct oil? You should be running 20W50 weight oil in your engine. The next most likely problem is the oil pressure sending unit. I'd replace that before I'd go tearing into the engine. I don't work on the Twin Cam engine but I think the oil pressure sending unit is located down low on the engine on the right front. There should be a wire connected to it. Make sure that wire is tight.

Good Luck

Your bike came from the factory with H-D Syn3 20W50 synthetic engine oil. There are many other brands that are very good oils. Amsoil, Mobil V-Twin, Royal Purple, Red LIne and others. Check their websites for compatibility and recommendations. Harley recommends using oils that are rated for use in diesel engines of 20W50 viscosity.

I have a 1999 fatboy what oil do I use in engine, trans & primary?


On a '99 Fatboy, you can use H-D Syn3 20W50 engine oil in all three locations. But, you can use most any lubricant you wish as long as it meets Harley's specifications. Amsoil, Royal Purple, Mobil V-Twin, just check the manufacturer's website for compatibility. On the Evo engines, I use H-D or Mobil V-Twin synthetic 20W50 engine oil. I use nothing but H-D transmission and primary lubricant in those two locations.

Oil capacity and regular or synthetic//


If changing your filter as well as the oil, your bike should take three quarts of oil as best as I know. Always check your oil using the dipstick when you change it. Change the oil and filter and add three quarts, start the engine and run it just a bit, two or three minutes. Check the oil level with the dipstick. The dipstick has two marks on it. The upper mark is 'FULL HOT" while the lower mark is 'FULL COLD'. Make sure your oil level is between the two marks and never overfill.

As for regular petroleum based oil or synthetic, you're 2001 machine came from the factory with H-D's Syn 3 20W50 synthetic oil in the engine, the primary, and the transmission. I'd recommend sticking with the synthetic oil but it must meet H-D's specification. Not all synthetics do. Matter of fact, very few do. Some that do is Amsoil, Royal Purple, and Mobil V-Twin.

Good Luck

What is the most practical synthetic motor oil to use on a 2010 harley trike


You can use most any synthetic oil as long as it meets Harley's specs provided the bike is powered by a Harley engine. The fact that it's a trike has nothing to do with the engine lubrication requirements. Harley-Davidson's Syn3 synthetic oil is what H-D recommends. But, you can use any synthetic oil as long as it is 20W50 weight and meets API SG/CG4 or better ratings. The CG or better rating is what you are looking for. It is a rating for oil sufficient for use in a diesel engine. There are several manufacturers that make this type of oil. Mobil makes it's V-Twin Synthetic, Amsoil, Royal Purple, and many others. Just make sure it's rated for use in diesel engines. It has the "high pressure additives" necessary to meet Harley's specs. But, use of an unapproved oil may void the warranty on your 2010 engine. Good Luck!

TRANSMISSION SERVICING


Most are using Syn3 oil in engine, tranny, and primary.
This simplifies this, and is a decent oil.
32oz of oil in primary.
20-24oz of oil in tranny
99851-05 primary case/ trans oil(Conv Oil)

there are other brands that surpass the syn3 oil but it takes some hunting around to find a supply.
Ammsol is one such brand and they recommend.
20w50 engine
15w40 primary
75w90 tranny

Hope this is of some assistance
