Diesel power

Let's see who helps me
the engine is exhausted when we put it to work, it is as if I had no strength, I think it is the pump, it is not well synchronized

Hello friend, I recommend that before touching the pumps you begin by discarding, the air filter, the petroles filters, also thickens well, when popnes to work the engine loses power or speed if this is last can be the lucky clutch

I thank you for the answer, the Filters of ACPM is new and we remove it only to try, in a 5 -minute question but it still runs out.
The engine is installed in a small excavator is from a friend of mine and told me that a few days ago I change the pump so I think it is.
I will find out the engine model well to see if anyone knows the synchronization of this, \ "to how many degrees \".

thank you
