I have a new to me year 2000, 2050 with 1900 hours on it. I'd like to get ready for the 2000 hour service. Can anyone tell me what the filter numbers are? I know it sounds like a stupid question, but the numbers on my filters are either unreadable, or don't have a brand name so the number is pretty much useless. I need air, engine oil, and both hydraulic oil filter numbers. Thanks a lot, Joe
