MANIFOLD 1B6016 - Caterpillar

EL200B Excavators need to be updated to a new injector design released for that machine. The new injectors have a different orifice size to help eliminate black smoke problems reported on some earlier machines. When replacing injectors on E200B and EL200B Excavators, use injector part number 7E8729 if available. Reset the fuel setting and timing if the injectors are available. See Action Required. Also, install a fuel hand priming pump and primary filter per the June 22, 1990 Service Letter - PS4442.
