Note: For LDA 450, LDA 510, LDA 96, LDA 97, LDA 820 out-of-production engines, the repair speci-
cations are equal to those of the engines specied in the table. 3 LD 451/S, 3LD 510/S engines,
which are currently produced, not specied in the table, turn anticlockwise ( seen from the ywhe-
el side), and are provided with the same feature as 3LD450 and 3LD510engines.
