I am about to put a LOT of hours on a MEP-806B that has ~ 460 hours on it.
The oil & air filters were changed @ 405 Hours, according to a hand written note on the air filter canister.
I've scanned though the TM, & specifically checked the "TABLE 4-3. UNIT PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)", but it doesn't mention anything about adjusting the valves.
I found a John Deere 6068 service manual dated 1993 & maybe updated 1997, so it might not be relevant to my JD 6068TF151A, C engine dated 5/2011, but it states that the valves should be adjusted at 400 hours.
So, my question is this: Does anybody know if, IN GENERAL, preventative maintenance on MEP units included adjusting the valves?
I checked the valve cover & didn't see any tool marks around the access plugs on the valve cover, indicating they had been removed:
Aha!!
I just found this in the ARMY TM 9-2815-260-24:
4 M 1500 (ie, 1,500 Hours) Engine Valves Adjust engine valves at Direct Support maintenance level. See paragraph 4.7.2.
So, it looks like these valves need to be adjusted @ 1,500 hours & the entire engine should be pulled to perform the work:
I answered my own question, but I wanted to share what I found in case anybody else had the same question.
Cheers!!
