I am changing my fluids, and I would like to know what to torque the various fittings at: the 3 derby cover screws, the primary drain plug; The oil tank drain plug; the transmission drain plug. I’ve looked at my Clymer and the HD manual as well as various web sites. All that I am coming up with is “snuggly”. I’d like to be a little more correct on my ’90 Harley.

On a bike this old, you should use recommended torque specs for reference only. Components have been in service for 25+ years. If you follow recommended torque specs, you may strip aluminum threads, or not tighten a component securely enough. You need to go by feel. Make sure your hardware and hardware allotments are clean and use Loctite.
- Clutch/inspection cover screws: 84-108 inch lbs
- Drain plugs: 14-22 foot lbs
