Well heres my trouble I recently picked up a 3444 with the 154 diesel enging. It starts good, sounds good, doesnt smoke, but seems gutless to me, if i were to hook it up to the old worn out h the 3444 would get drug all around the farm. It has new fuel filter, air filter is clean, Injector pump was replaced about a year and a half ago by the previous owner and one injector was replace at the same time. She bogs down and bellows black smoke in 4-low going up an incline. What could be wrong with this thing, everyone tells me it should be good and strong but its just gutless in my opinoin. What am i missing? Thanks for any help
 

Clean and service the air intake system. If it has a dry filter, replace it. If it has the oil bath system, clean it thoroughly and refill with proper amount and type of oil.
 
After you check what the other fellows have mentioned, check the valve lash and valve lift, then maybe a compression check. Since you have black smoke, this sounds like an air flow problem.
 
The air cleaner system is nice and clean and been refilled with 30 wt oil, the timing was checked and was slightly retarded, that made a very slight difference,the fuel shut off is completely forward. There is not a blower so that is ruled out. I am yet to check the valve lash i believe it is supposed to be set at .020 with the engine at operating temperature please correct me if i am wrong i will also make sure to check the compression tomorrow. thanks for all your help so far.
