Engine #4 - Harley Clutch Unit
Life's a bitch... Thank God there's Harleys...
Here's the pictures we made during cleaning, inspection and re-assembly of the Harley clutch unit of our 1973 Ironhead Sportster engine. Fortunately the wear and tear on the existing clutch plates was only minimal, so we could re-use the original Harley Davidson parts.
Here L is cleaning the clutch parts in our parts washer.
After the parts washer treatment, T cleans the clutch parts once again using thinner, makes sure there's no grease or oil left on the clutch plates,
rubs the plates dry, and does the final inspection.
