Sorry everyone, I'm going a little nuts with the all the manuals... and tables... and schedules...
I think I've got all the maintenance items on my spreadsheet except for the fuel/water separator filter. I'm having trouble finding the recommended change interval on that.
Freightliner says "See the applicable engine operation and maintenance manual for fuel/water separator element replacing intervals." I checked the Cummins book and could not find any schedules for it. I could have missed it, but I really tried to find it.
Does anyone have factual information for the schedule on this?
Thanks for the help!
