Anyone out there have a Cat part number for the internal splined socket that is used to remove the nut that holds the injection nozzle in the pre-cup on a D315 engine from a 955 Traxcavator, s/n 12A4296 motor? The splined nut is about 1" in Diameter. I don't have any info on this unit. Most of the other retaining nuts are hex shaped. This must have been a year all it's own. Thanks in advance, Larry.
PS. Have a bad injector nozzle, that's why a socket is needed.
