Milwaukee-Eight 114/117 Softail & Touring, Evolution Sportster & Revolution Max
HARLEY-DAVIDSON LUBRICATION & WRENCHING ARCHITECTURE
Harley-Davidson spans three distinct lubrication architectures: Milwaukee-Eight Softail and Touring models (Fat Boy 114, Breakout 117, Low Rider ST, Street Glide) use a dry-sump 3-Hole system separating SAE 20W-50 engine oil, Formula+ primary chaincase/wet-clutch fluid, and transmission gear lube. Air-cooled Evolution Sportsters (Iron 883, Forty-Eight) use a 2-Hole layout (dry-sump engine tank + shared primary/transmission fluid), while liquid-cooled Revolution Max engines (Sportster S, Nightster 975, Pan America 1250) share a single unitized SAE 15W-50 sump. Crucially, Harley oil levels are checked hot on the side stand (Jiffy Stand), not upright.
