Transmission Oil reservoir

2004 Fatboy, 32,000 miles.
Is the primary and transmission sharing the same oil ??
Or is it separate. I just drained and chnged the Transmission oil, and this morning my primary is leaking a little....is that because I over filled the Transmission oil. It says it takes 1 qt. and that's what I put in.....my primary hadn't been leaking previously.
I figure to split the primary, clean it up and replace the gasket.....should I now drain the the Transmission oil again to do this ?

2003 Fatboy while winterizing drained the oil very little came out however there was oil in filter..New filter,filled with oil started sounds like usual then the oil shot out of the cap where you insert...


On the softail model Harley Davidson's the oil tank is external and sits up higher than the engine crank case and oil pump. when these bikes sit for an amount of time the oil gravitates from the tank to the crank case. starting may seem sightly harder and seem like the battery is going dead. the bike should be started in knowing that you had oil in it to start with and no giant leak puddle underneath of it. warm up the engine and then drain the oil out of the tank. the reason why your filler cap popped off is because you had probably 2 1/2 to 3 quarts to much engine oil in the bike. so drain the oil from the tank at the drain pug at the bottom of the hose on the high (right side ) of the bike where the swing arm meets the frame (it is a 5/8 socket) put the drain plug back in run the bike for about 5 minutes inspecting with a flashlight continuously that oil is circulating back into the tank. then dran it again and replace with new oil.

Caramel (coffee) colored oil


It's trans fluid. It came out of the vent tube just above the primary cover on the top cover of the trans. If you look at the tube, the inside will be wet. Run the bike up to operating temp. Check upright and level.

1 qt oil every 1000 miles


kev, check you have the right level on your dip stick, oil must be on upper mark when donk cold.also ensure you are running the correct oil weight for your donk.
engine may be running hot; which means one way oil can go missing is its being burnt.
also check your primary drive,clutch oil level ,not sure as i have 80cube evo, but you may find your oil in there due to bad oil seal internally. im no expert but these may be of help.

Changing fluids


Trans plug is under the Primary cover ( Left side ) and the Oil line is under the frame on the left side. Look for a oil line with a plug attatched to it. Run the bike up to operating temp. Primary and trans are the same thing ( Sport Trans fluid ) 1Qt in the primary ( fill throught the little cover on the side of the primary, and fill the oil through the oil tank. Put a little oil in the filter too, before installing, this will give the motor a little bit of oil until the rest of it makes it way through. You'll also need 1 p/n 11105 for the drain plug on the primary.

Gear Box oil change How do i do it??


Trans fluid and primary fluid are the same oil , The drain plug is under the laft side primary cover. 1 qt of oil goes in the inspection cover on the top side of the primary cover. The oil drain is a hose under the left side by the frame rail. Look for a oil line with a plug. fill with approx 3 qts through the oil tank. Make sure you get the bike up to operating temp before dropping the fluid.

98 fatboy engine noise.


Harley's do run hot, anywhere from 220 to 240 normally, and a little hotter this time of year. I suggest running a straight weight oil, and a little heavier weight in the summer. I use Valvoline VR-1 30 weight most of the year, and 50 or 60 weight in the hot summer, and I use Lucas 20w50 primary/trans for the primary and tranny. I don't bother with the extremely high prices of the HD oils. For the whining noise, you need to determine which side of the engine it's coming from. Whining will almost always be in the bottom end. There's nothing in the top end that should whine, and if there is whining from the top, it's usually an air leak around the carb. Start by checking the fluid levels in the tranny, and primary. These are the two most common areas to pick up a whining noise. If it's coming from the left, it's going to be in the primary, and usually this is caused by low fluid levels. From the right, it's going to be either the tranny, low fluid, or the oil pump. The oil pump is a gear type system. If you're running a light weight oil, say a 10w40 or HD 20w50, when the engine heats up and the oil thins, it can cause the oil pump gears to whine a bit, especially in the summer heat. So, check the fluid levels, if they check good, then change the oil, since the summer is coming to an end, go with a straight 30 weight. This should clear up the whining noise. If it doesn't, get back to me with the exact location the noise is coming from, and we'll go to the next level of diagnosing the whine, but I believe that this will cure it.

Do new 1450cc harley davidson engines use same oils in engine and transmission ?


If you use Harley oil from the dealer, you use 20-50w oil for the engine and they use special formulated lube that you use in both the transmission and primary,Some people do use the same oil in the engine,tranny and primary, I would not recommend it
