I am about to replace the valve cover gasket on a 2018 Cat 259D. I was looking to see if anyone had the instructions from the service manual for this replacement? Or any tips that would be helpful. Thanks in advance.

    Is there any other parts that are needed to complete this service?

    You're asking for information but failing to supply a machine Serial Number.
