I'm currently rebuilding the engine on a John Deere 690B excavator. I've come across a few questions that I'd like to ask, but I'm seeing conflicting reports on what's on-topic here.
Questions related to the maintenance and repair of motor vehicles and their accessories, internal combustion engines, even in applications other than automotive so long as the question is related to engine or engine accessories.
This well-received answer from a moderator to a question asking if the scope should be broadened to include excavators (explicitly mentioned in the question) says that they shouldn't be included.
The two answers to this question asking whether large (nowhere near an excavator, though) machinery should be on-topic seem to favor including it.
So I'm looking for some consistency here: Are questions about large diesel engines on-topic?
