Reman Fuel Injectors Improved
There have been some issues with Caterpillar mechanical unit injectors on models: 3114 ATAAC NA D1 (S/N: 5YL1-Up); 3114 (S/N: 9LL1-Up); 3116 ATTAC D1 (S/N: 2BK1-Up; 7SF1-Up); 3116 (S/N CSM1-Up; 2FR1-Up; 7HS1-Up; 9Gk1-Up; 7HJ1-Up and 9CJ1-Up); 3116 ATAAC (S/N: 7JL1-Up); and 3116 T (S/N: 9LN1-Up and 9YN1-Up).
The remanufactured mechanical unit injectors are now shipped with the rack in the fuel “off” position in order to eliminate the need to move the fuel rack before installation into the cylinder head.
The fuel rack on the mechanical unit injectors should not be moved without compressing the tappet spring.
The issue is the dragging of the fuel rack and was caused by the process of remanufacturing the cones for the fuel injectors. The remanufactured cones were causing the rack to drag. The cones now are remanufactured in order to eliminate the fuel rack from dragging.
The change in the process of remanufacturing the cones for the injectors has caused the cones to have some discoloration. The change in the appearance of the remanufactured cones is normal. The discoloration will not affect the performance of the fuel injectors.
