TRUNNION GP-ENGINE 1W1218 - Caterpillar

3200, 3300, And 3400 Industrial, Marine, And Generator Set EnginesAll 7000 series fuel injection nozzles have new date code information. The new date code contains the day, month, and year the nozzle was manufactured. The previous code contained only the month and year. The new method provides tighter control of a specific time period for tracking changes. The first two places (DD) in the date code indicate the day of the month. The third place in the date code (M) is a letter, "A" through "M" excluding "I" that indicate the month. The last two places (YY) in the date code indicate the year. For example, the date code "05A94", would indicate the nozzle was manufactured on January 5, 1994.
