Changing Primary Fluid In A Harley Davidson Sportster 883

     Do you have a Harley Davidson Sportster and need your primary fluid changed? Don't want to pay the T-shirt shop to do it? Well, do it yourself, it's easy, cheap and won't take much of your time. Here's how:

- Take your bike out for a ride to warm up the primary fluid. It will drain out better this way. Let it cool for about 15 minutes or so.

- Put an oil drain pan under the primary case cover which is located on the left side of your engine.

- Remove the drain bolt using a ratchet and a T-40 Torx bit. Let the fluid drain into the pan until it is empty. I like to rock the bike back and forth to get a little more fluid out.

- Remove the drain plug o-ring and clean the plug thoroughly. Install a new o-ring and replace the drain plug. Using a torque wrench, tighten the plug to 6 foot pounds.

- Using a T-27 Torx bit, remove the clutch inspection cover and it's gasket. If the gasket looks bad, replace it with a new one, otherwise the old one is okay to use.

- Fill the primary case with new Harley Davidson Formula+ primary chain case oil until the fluid is level with the bottom spring on the clutch assembly face.

- Replace the inspection cover and gasket and loosely tighten the bolts down. Using a torque wrench, tighten the bolts in a star pattern to 10 foot-pounds.

- Clean up any spilled fluid and start the bike. Check for any leaks.

     That's it, you are done. Less than a half an hour and money saved in you pocket.
