Which of the three drain plugs. Primary is on primary case below derby cover; transmission is on right side middle bottom of transmission, engine is at bottom of right rear frame down tube intermediately forward of rear tire. ALL are 5/8 inch hex plugs with 1/4 inch Allen socket in the middle of the plug.

the drain plug will be situated underneath the engine in between the two cylinders. Before changing the oil if possible run the engine for a few minutes to warm the oil then remove the sump or drain plug, and dont forget to change the oil filter as well.

on the oil tank there should be a drain hose that goes down and hitches to the frame on the bottom of the frame there should be a drain bolt. That is your engine oil drain plug and should be on the right side

ten ounces in each side . Make sure they are drained completely to avoud overfill

Fatboy, drains from the oil tank bottom right side rubber tube goes down to frame, bolt in frame is plug. Have to get to it from underneath. This is only engine oil. After oil change three quarts, if change filter 3.5 quarts.
Hope this helps.

I have a 05 Fatboy and the drain plug is hidden inside the frame rail on the right side by the swing arm it's a 5/8s plug.
