Found pool of oil under my 03 fat boy transmission is empty what would have caused this ?

First off, check underneath and see if the transmission drain plug worked loose or came out.
The other thing it could be is a bad transmission main shaft seal, behind the drive belt pulley, which is behind the primary cover.

Need to know engine oil type and transmission oil type and capacities for 2004 fxdwgi

Your bike came new from the factory with Harley-Davidson Syn3 20W50 synthetic engine oil in the engine, transmission, and primary. You can change brands of any oil you wish but go online and see what the manufacturer recommends. Some other manufacturers of lubricants are Amsoil, Royal Purple, Mobil, Golden Spectro, and RevTech. Just follow their recommendations. The engine holds approx. 3 quarts, the primary holds approx. a quart, and the transmission holds 20-24 ounces. Always check the level with the dipstick once you change the oil. The dipsticks have two marks on them. The upper mark is "FULL HOT" and the lower mark is "FULL COLD". Do not overfill.

Good Luck

I need to due an oilm change on a recently perchased '88 sofrtail with 5 speed and belt drive.what do I need to do?

Find the oil drain. It's located below the transmission on the frame behind the exhaust pipes. It may be a hose with a plug in it or the hose my plug onto the crossmember of the frame in that area. If it's in the crossmember, the drain plug is underneath the crossmember. Remove the plug and drain the oil. Replace the oil filter with a new one. Refill the oil tank with three quarts of 20W50 oil. Check the oil after your run the engine long enough to get it to normal operating temp. There are two marks on the dipstick. The top mark is "FULL HOT" the lower mark is "FULL COLD". Do not overfill and check the oil with the bike on the side stand.

To change the oil in your primary, Look below the rear of the outer primary cover way back where the clutch is loctated. Drain the oil and remove the derby cover. Stand the bike straight up and refill the primary with H-D Primary Lube. Fill the primary until the level of oil is just below the lowest portion of the clutch spring in the clutch pack. Do not overfill as the clutch will drag and you will not be able to find neutral position in the transmission with the engine running. About a quart of lube is sufficient.

The transmission drain is a pipe plug on the right side of the transmission. Drain and refill with 20-24 ounces of H-D transmission lube.

Your bike originally came from the factory with H-D Syn3 synthetic 20W50 engine oil in all three areas.

Good Luck

Fluid capasities in a 2002 dyna twin cam. oil, trans,primary?

Engine oil - 3 qts
Primary oil - 34-42 oz.
transmission - 20-24 ounces.

The engine oil and the transmission oil both have dipsticks. Maintain the oil levels according to the dipstick indications. Each dipstick has two marks. The top mark represents "FULL HOT" while the lower mark represents "FULL COLD" . Check the engine oil with the bike on the side stand. Check the transmission oil with the bike standing straight up.

On the primary, check or add oil with the bike standing straight up. Do not overfill. The oil level should be no higher than the lowest edge of the clutch spring. If you put too much oil in the primary, the clutch will drag making it impossible to find neutral with the engine running.

Good Luck

2003 harley davison superglide fxd questions concerning oil

The engine takes three quarts of oil with a filter change. Now, always check the oil after filling. The dipstick has two marks on it. The upper mark is "FULL HOT" and the lower mark is "FULL COLD". Do not overfill.

The transmission holds 20-24 ounces of transmission lube. It too has a dipstick on it.

The primary holds 36-42 ounces of oil. Do not overfill this either because too much oil will make your clutch seem like it's dragging. You will not be able to find neutral with the engine running.

Good luck

Oil for a Harley Davidson Sportster 1991

Harley-Davidson recommends their 20W50 petroleum based oil for the engine. You can use the H-D Syn 3 20W50 synthetic oil in the engine but I don't recommend it in the primary/transmission area. You can use any 20W50 oil as long as the API rating has a "C" rating for use in diesel engines. Look for the round circle somewhere on the container that had the API initials in it. It should say something like "SJ/CG". What you're looking for the "C" rating. If you wish to use a specific brand of oil, got to their website and look for their recommendations.

In the transmission, Harley recommends their Semi-Synthetic Primary and Transmission lubricant for Sportsters. The lube lubricates both the primary and the transmission on the Sportster. I don't recommmend full synthetic transmission lube on any bike built before 1995 as it will cause the gears to run noisey. In 1995, Harley changed the back cut on the gears and this made use of full synthetic lube more quiet running. Of course, you can use the full synthetic from a lubrication view point. It's just a bit noisey for my taste.

Whatever you use, make sure you go online and check the manufacturer's suggestion for use.

Good Luck

I,ve got a 2008 Ultra classic, and want to change the fluids. It's got 8000 miles, and i dont have a owners manual. the oil, i can figure out , but the trans, and the primary I dont have an idea.

On the bottom of your transmission, there are two drain plugs, one for the transmission and one for the engine oil. The plug in the center is the transmission drain plug and the one toward the left front is the engine oil drain. The primary drain is a small pipe plug that takes a Torx wrench located at the bottom of the primary cover towards the rear of the bike.

Engine oil three quarts with filter. Then start the bike and let it run for a few minutes. Shut down the engine and check the oil level with the dipstick. The dipstick has two marks on it. "Full Cold" and "Full Hot". Fill to the full cold mark.

Transmission takes 20-24 ounces of oil and the primary takes 38-44 ounces of oil. Do not overfill the primary as it will cause your clutch to drag. All three sections take H-D Syn3 20W50 synthetic engine oil.

How do I change all my fluids on a FLHTC 2005

There are three areas that you have to service, engine oil, primary oil, and transmission.

To change the engine oil, underneath the transmission, you'll find two drain plugs. The drain plug nearest the left side of the engine is the the engine oil drain. Warm the engine a bit and drain the oil. Change the oil filter. This is a messy job so put something down to catch the oil as it runs out of the filter. Replace drain plug and refill with oil.

The plug nearest the center of the transmission is the transmission drain. Remove the plug to drain the transmission. Once drained replace the plug and refill the transmission through the transmission fill hole in the chrome cover on the right side of the transmission.

To change the primary oil, underneath the primary outer cover very near the rear of this cover is a small drain plug. It takes a Torx wrench to get the plug out. Remove the plug to drain the oil from the primary. Remove the derby cover over the clutch. Refill with oil through the derby cover hole.

Your bike probably came with H-D Syn3 oil. You can replace the oil with this or any other oil as long as it carries a rating for use in a diesel engine. Here, it must have an API code of "C", example "SJ/CG4". Four quarts of engine oil, Add three quarts of oil and check. Fill to proper level with the fourth. Your dipstick is marked with a "Full Cold" and "Full Hot" mark. Fill to "Full Cold" mark and check again after warming up the engine.

Use Syn3 in the primary or 30 weight oil, 40-44 ounces. With the bike standing nearly straight up, the fluid level should be to the bottom of the clutch spring, large black disc in the center of the clutch. It's a diaphragm type spring.

Use Syn3 in the transmission, 20-24 fluid ounces. Check with the dip stick again with the bike standing straight up.
