If you disassemble all three of the units .... you will see how small the path ways are internally for the oil to go to the cooler and go thru the unit to get to the motor....
The passage ways on the Mocal and Earls have a relatively small section to transfer the oil in either direction and the thermostat is relatively small.....
The Canton unit is much larger in it's ability to move a larger volume of oil.....and the Thermostat is also much larger and will pass oil with out any restriction based on the size of the unit...... The pressure drop across the thermostat is about 2.5#lbs at 85#lbs of oil pressure
It's a Caltherm Thermostat used in the big Diesel's motors and not a small device......which is why it needs the larger housing that Canton uses..... so it can flow the large volume of oil
