The drain plug is on the bottom of the transmission. There are two there and the engine oil drain is the one that is the "most prominent". It's usually on the left front corner of the oil pan. The oil tank takes three quarts when the filter is changed as well. If you don't change the filter add only two quarts and check using the dipstick. Once filled, check the oil using he dipstick while the bike is on the side stand. There are two marks. The upper mark is the "FULL HOT" mark and the lower mark is the "FULL COLD" mark. Do not overfill.

Good luck

Metal in the primary oil

This is not uncommon on Harleys with high mileage or which have not been properly maintained. Change the primary oil, and verify that the primary chain is not loose or compromised. Change the primary oil again within 1000 miles or so, verifying that there is not an unusual amount of metal in the oil again. If there is, remove the primary cover entirely and replace any parts that are wearing unusually.

What is the oil capacity for a 1987 FLHTC Electra Glide Classic

I think it's three quarts but the tank has a dip stick on it. After draining the tank and changing the oil filter, pour three quarts into the tank. The dipstick has two marks on it. Check the level with the bike on the side stand. The upper mark is "FULL HOT" and the lower mark is "FULL COLD". Top the oil level off to the lower mark and recheck once you've ridden the bike.

Goodl Luck

Need to change oil

Look under the transmission. This is the oil pan. There are two drain plugs. The one in the center is the transmission drain plug. The drain plug near the front on the left side is the engine oil drain plug. Three quarts of oil with a filter change then check the level on the stick. There are two marks on the dipstick. One is "Full Cold" and the other is "Full Hot". Do not overfill.

Want to change oilneed toknow where the plugs are and how much oil

Underneath the transmission there are two drain plugs. The center one is the transmission drain. The drain plug near the front left is the engine oil drain. I always add three quarts with the filter change, start the engine and run a few minutes and then check the oil with the dipstick. There are two marks on the stick. One is "Full Cold" and one is "Full Hot". Fill to the full cold mark, do not overfill.

Good luck

How do i check the primary oil in my 2005 harley davidson electra glide. i changed the oil and added 32oz of oil as directed by the owners manual but i cannot see the oil in the clutch inspection cover....

if you put 32 oz of primary oil in the primary case then you have enough oil in there already. Never put more then 1 full quart or you will have leak issues. The way I do it is to have the bike upright and level and look through the primary inspection cover and as long as the chain is in the oil a little bit then your fine.

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.
