I revisited this - the repair manual -and find a lot of M42 stuff.
Click "Engine 11" on main group page.
Select M42 on next page.
Go back to top and click "Constr. Group"
Select "Engine - disassemble and assemble" or a specific group.
Click arrows at top to page through.
I had never really looked at this before. There's also "Torque Values" and "Technical data". Clearances, settings and all kinds of stuff are in there.
