I'm new to Harley's and was wondering how my primary is driven? Was thinking about changing derby cover and didn't want to make a mess if there is fluid behind it. No inspection cover so that made me think it was belt driven but want to be sure. Thanks.
It's still a chain drive, and there is more than a quart of fluid. The inspection cover was removed a few years ago when H-D changed to an automatic chain tensioner.
The fluid level is low enough that just removing the derby cover won't cause fluid to run out. In fact, the gasket covers the entire opening and usually stays in place until you peel it off after removing the cover. If you have no need to inspect the clutch or add fluid, just leave the gasket in place and bolt up the new cover. Don't overtighten the fasteners, the spec is 96 inch pounds.
