When a four stroke engine begins to sound like a two stroke engine, you know it's turning much too fast for it's own good.

Don't even think you can fix it yourself unless you have a test bench to recalibrate it, and even then… Test benches start at around $20 large. And unless you have the proper training and understanding, don't even mess with the governor. Ego's have destroyed machines and killed people. Do you feel lucky?
There are no shims to “adjust pump shots”. The scroll and helix orientation is determined by the rack position, and the barrel and plunger assembly is controlled by the depth of the barrel in relation to the cam lift, which in effect establishes the fuel delivery quantity and timing for a particular cylinder. You can only set this accurately on a test bench.

Spring Valley is correct. Internal parts for these pumps are not available.
If you have metal pieces coming out of the drain hole, don't try to run the engine, those could be governor pieces and you would risk an overspeed condition. If on the other hand, the particles are more like grit or sand, flush the pump and governor thoroughly with diesel, blow out with compressed air and refill with fresh oil.

I thought that was a CAV/Lucas pump. Oh well.
What he most has is the in-line Bosch or Diesel KIKI type.
Well, that's not the pic I wanted.

I'll speculate because the fuel tank is right up against the rear of the valve cover and cylinder head.

I posted this earlier. I forgot that most dozers don't have compression releases.
