My M813 continues to have some random power problems on acceleration. The characteristics are that it looses power and becomes gutless for about 5-20 seconds and then gains power again. This is about the time that I hit the 3rd to 4th gear acceleration. Sometimes the RPMs stay up and float for a bit then drop back as normal. I was comparing vehicles with two friends yesterday and one suggested that the governor could be sticky.
Looking through the parts -34 and -34p TMs, the governor on the Cummins seems to be sealed under a sealing wire and accessing it seems to imply that if you make changes a re-calibration of the fuel pump is required. Does a simple servicing of this area require a re-calibration? ie If I change none of the shims and just check the operation of the governor weights and such should there be any requirement for a re-calibration on the bench test gear?
Fuel does not appear to have problems. I'm not showing any water any more on pre-driving service. When I was seeing water it was showing about 3-4 table spoons of water. It has a new fuel filter which did have some sludge in/on it. The previous drains of the fuel system showed some of that sludge in with the water. I have not drained the full fuel system. This could be done however.
Could it be as simple as the fuel filter at the fuel pump being partially blocked by some of that gunk. Looking through the -34p that did appear to be an item to check though I don't recall seeing that in the -10 TM.
Thanks!
