Too slow in other words .......Although I can say that when the batteries are fresh it cranks at about 3/4 the speed of a brand new 3406C that we bought to put in a local use dump truck.
If the starter was replaced recently then I'd look very hard at the cables and connections in the battery/starting circuit.
As an aside what viscosity of oil do you have in the hydraulic system..?
