Default How much primary oil?

I have an 01 electra glide. what is the correct amount of primary oil? I have heard that the manual calls for 32oz. I have also read that people put in 38oz but I believe that is for the newer models 07 & up. just want to make sure.
thanks

My service manual 01 RK, states the capacity at 32 oz. however it also states "these are estimates and the level should be check according to the methods in chapter.." (yada yada yada...)

32oz sounds correct if I remember.

I think, a quart.

Do a google search.

Buying a manual wouldn't hurt.

From the service manual for the 2000 FLT models (same primary as on the 01's):
"With the vehicle standing upright, the level of the lubricant must be at the bottom edge of the diaphragm spring or 2 3/4 inches from the centerline of the clutch adjuster screw. The primary chaincase capacity is 32 ounces."

When I do my primary, for lack of something better, I put an ordinary brick under the jiffy stand. This gets the bike "close to vertical", but still a few degrees toward the left side. It won't tip over without an effort, but be careful anyway.

For some reason, 32 ounces may not actually bring the fluid up to the bottom edge of the spring. If that's the case, add a little at a time until it does, and try to keep track as to how many ounces "over 32" you've put in. Then, next time, just measure out this amount and pour it in. Works for me.

I have a display stand, which makes that check very easy! Fishrrman gives the correct level. If the chaincase is bone dry, say after a primary rebuild, it may well take 32 ounces, but when doing a normal service oil change it will probably take less.

You should never fill any oil reservoir with the stated quantity - always check for the correct level.

The important thing is that the diaphragm springs are "just" covered down at the bottom of the clutch pack... with the bike vertical. If you over-fill it based on ounces recommendations alone, or take shortcuts by not getting the bike vertical, then it might make neutral hard to find. So go visual if you are simply changing the primary case lubricant.

If you are rebuilding, then most likely it will take the 32 ounces once all of the oil is distributed to all of the surface areas within the clutch assembly, chain, and compensator parts.

notice a common theme here?

but, you don't even need a service manual for this. this information is pretty clearly spelled out in your owners manual. and if you don't have an owners manual, you can register online at h-d.com and look it up online.
(but having a service manual is a very handy thing to have)
