Note:
Only loosen counterbalance weight securing bolt -2-; do not remove it.
-
‒ Unbolt retaining frame -3- from cylinder block and remove retaining frame with counterbalance shaft.
-
‒ Lay retaining frame aside on a clean surface.
-
‒ Remove securing bolt from counterbalance shaft.
-

Installing
-
‒ Oil bearing's running surfaces.
-
‒ Set counterbalance shaft in bearing.
