The rating plate with the loading diagram and serial number is affixed to the closing arm 
on the right side of the vehicle as viewed in the forward direction of travel. 
 
 
 
 
Position 2 
The same rating plate is also affixed to the inside of the power pack cover. 
 
 
 
 
Position 3 
The serial number is also stamped into the mounting flange on the left as viewed in the 
forward direction of travel.
