Exhaust camshaft bush
Exhaust camshaft bush, PN 70-3823 (aka E3823), fitted in the crankcase where the exhaust camshaft runs.
This is the exhaust camshaft bush, part number 70-3823, listed under the CRANKCASE figure in the parts books. Older books show it as E3823, so if you're working from an early manual and see that number, it's the same physical part. It sits in the crankcase where the exhaust camshaft rides, giving the cam a wear surface separate from the case casting itself.

Our catalog record shows this bush appearing across rows spanning 1964 through 1974, which tells you it had a long service life in the parts books, though we'd want to confirm exact fitment for your specific engine before you order.
When you're rebuilding a bottom end and the cam is showing play, this is the kind of bush that gets checked and replaced. Have your case measured for wear before assuming a new bush alone will bring clearance back into spec.
