PROBLEM
Incorrect fuel injectors may be installed on certain AD45B and AD55 Underground Articulated Trucks. The 291-5911 Injector Gp-Fuel listed on SIS Web was the incorrect part number to use for replacement. This only affects machines that may have had an injector or injectors replaced during field service or by the customer. The correct fuel injectors have been installed in the engines from the factory.
