Primary oil change 4 questions
fxdwg 2010
So i just changed the primary fluids ... I took out about 1 liter so that's what I putted back no mention of the quantities in the owner manual so is that quantity correct ?
Second theyre were some metal residu on the magnetic nut, nothing alarming but ... I looked what I could look at by the derby, what should I inspect ?
Third In the owners manual they specify to change the gasket, ... normaly the derby should have one ? I got a rubber ring thats all did the guy before forgot it or in 2010 theyre arent one ?
Fourth the oil I took out was greyish... I putted this in the engine, the trans and now the primary :

The metal shavings are just clutch material and such that gets picked up by the magnet. The fluid turns a grayish color from the clutch, moisture would turn it white. There is much debate about the fluid type that you can use but bottom line is that you really shouldn't use any oil with friction modifiers in it like automotive oil, they can make your clutch slip and the damage is permanent. Harley sells oit that will work or you can use a diesel specific oil like Shell Rotella T which doesn't have friction modifiers. The orange o ring is the gasket and I still have my factory one on after 25k miles and 5 changes, some older models and aftermarket covers use a paper gasket. What you requested was ADVICE. What I did was ADVISE you. Good luck

Thanks for the answer most of what I wanted been answered and everything I did Is fine. The oil I've putted in is for "racing" (yeah right) bike and got some additive for both wet and dry clutch in my own opinion its fine or better than the formula one .

The only question not quite answered that I was wondering about is probably the most important ... What should I inspect and how can I check if its right or wrong

Unless the 96" engine on a 2010 Dyna is different than a 96" engine on a 2010 touring model, the primary takes 38 oz for a normal change. If you remove the entire outer primary cover, it takes 45 oz. That's right out of the 2010 Touring Service Manual.
If you just visually fill the primary up to the bottom of the clutch basket, you're good to go.

What you used is probably okay. I changed mine to an oil for diesel engines as advised by a local shop. It made the clutch more grabby ( or less smooth ??) and I will dump it soon and try something else.
