Does the WA380-3 manual prove this is the S6D108-1 subvariant?
No. It identifies S6D108 without a suffix. Confirm the exact -1 build from the engine data plate and original part or arrangement number.
Will an S6D108-family engine suit every WA380-3?
No. The manual lists S6D108 for serial H20001-H20500 and S6D114E1 for H20501 onward. Verify the target machine serial.
