AS REQUIRED
1043568 Injector Pushrods(depending on the results of the inspection,0?6 pushrods may be needed for the rework? Only individual pushrods foundto be soft need to be replaced)AS REQUIRED
Injector Group(depending on the results of the pushrodinspection , 0-6 injectors may be needed for the rework? An injector shouldbe replaced only if the pushrod for that particular injector isfound to be soft and if the engine has more than 200 MILES (322KM) or 20 HOURS.)ACTION REQUIRED
Remove the valve covers.
Using a medium to coarse flat file against thecup of the pushrod, stroke the file.
If the push rod is soft you will feel a distinctdrag as the file digs into the material.
If the push rod is hard the file will feel likeit is passing over glass as the file slides across the hard surface.
If you are not certain if a pushrod is soft orhard CALL YOUR TC OR THE CAT PRODUCT ANALYST AT:(800)447-4986.
If a pushrod is soft, remove the rocker arm andreplace the pushrod. Tighten the rocker stand bolts according to the torquevalue found in Service Manual.
IF A PUSHROD IS FOUND TO BE SOFT AND THE ENGINEHAS MORE THAN 200 miles (322 KM) OR 20 hours on it replace onlythe injector that is driven by the soft pushrod. Lubricate the two largero-ring seals with engine oil and install the injectors. Tighten the injectorhold down
