Side Valve Tappet Covers - Late Model

If you look closely - there are small "ears" that stick out

on the inner covers.

You use this special tool (Noot had an original H-D one)

and lift up the cover, remove clip, and the ears

fit in notches to hold up the covers, so you

can adjust your tappets !

Then you pop the clips in (with square holes)

and undo the ears and the spring tension holds

the covers - and seals in the engine oil.
