What you are describing is almost always an advance issue. Try advancing the static timing on the engine about 1-1.5 degrees. mark where the pump is now and move it opposite of the direction of rotation. Look at the spec tag and it will have an arrow showing its rotation. Move the pump while the engine is not running about the thickness of a screw driver blade. Most times this does wonders. 3 cyl engines are very sensitive. Sometimes you have to play to find the sweet spot they run the best in. Al

Well Al you nailed it and it took about the blade width of a medium screwdriver.....1* roughly. I jumped out of bed and was on it before the sun crested the horizon. The pump limit allowed the rpms to increase to slightly above where they were telling me that i went the right way besides the smooth and much quieter running......considering a 4.4" diameter pistoned, 3 cyl., 4 stroke diesel.

In reading the A&I serv. manual, it said that some people hook the tractor to a dyno and tune the timing for max output which supports my assumptions about the manufacturing settings being "within a range" and not necessarily right on. Understanding that the production line has to keep rolling to make a profit. One wouldn't expect workers to sit there and play with timing to max out the HP on each tractor.

Thanks,
Mark

Later tractors were intentionally timed to sputter, solely for emissions reasons. The first time I called the service department to report this issue, I was told very clearly to not touch it. Soon after that, the "tamper resistant" pumps came out that do not allow a person to change the timing like you just did.

So the assembly line built a machine with the mechanic or consumer had no way to vary the timing if the tolerances added up and he had to put up with the rough running or noise in my case? I haven't paid any attention to pump mountings in tractors other than my 3000 when I overhauled it. If the timing is critical, like Al mentioned, that doesn't sound like a good idea for the consumer/mechanic.

From time to time I have read on this forum where some people say that some of these Ford engines are just noisy. Maybe they just need their timing tweaked a bit. Grin

EPA emissions regulations mandated that injection pumps be "tamper resistant" to discourage owners like you from doing exactly what you did. To accomplish that objective with rotary pumps, they removed the kidney slots in the pump that allowed for timing adjustments. In addition, the pump was bolted from the inside of the timing cover, requiring the drive gear to be popped off before one could reach the bolts.

I thought about possibly a timing issue but with such low hours didn't figure that would be it. But production lines are built with components which all have their tolerances and assembly testings are sometimes made with green/yellow/red, pass-fail areas on a test meter, maybe not pumps themselves, but other components that can affect timing. The assembly instructions say set the timing at 0 and that's for all the components built to support that assembly line with their tolerances coming down it. Surely makes sense.

Other thing is that this is the least potentially destructive thing I can change as opening up the fuel system and swapping out injectors on both tractors is just asking for trouble. I'll tweak it tomorrow and check back in.

Thanks for kicking in Al.......the pump guy. Grin.
