(1) The nozzle of the fuel injector is too worn and should be replaced.

(2) Carefully check for metal scratches. This metal wear can cause the plunger to jam or seize.

(3) There are bright spots or surface scratches on the upper, lower and middle parts of the plunger working surface, which are generally caused by the side thrust of the rocker arm. If there is no metal chipping or significant wear in these areas, the plunger is good for further use. If excessive wear occurs, a new plunger should be installed.

(4) The fine streaks on the length of the plunger movement are usually caused by the different thickness of the anti-rust penetration treatment layer. Plungers are safe for repeated use provided there is no significant surface wear.

(5) Check whether the plunger and the injector nozzle are cracked or loose, and whether they can be rotated by hand. Check the flange spring contact surface of the plunger nozzle for excessive wear or damage, check the plunger ball and seat for wear or cracks, check and remove the carbon deposits on the small outer diameter near the cone end of the plunger. Care should be taken during operation to prevent damage to the injector plunger, because once the plunger is damaged, it may be scrapped.

The width of the old oil return groove is 5.46mm, and the width of the large capacity plunger oil return groove is 6.73mm.
