    Cat 301.8

    $44 and available locally here in MA. I wonder if the major CAT dealers dont take from each others inventory beyond central warehousing. If you end up in a real bind, send me a message and I can ship one out to you.

    Cat 279c park brake issue

    the number you have showing (258-2801) is the work tool positioner valve. That valve cartridge and coil (item 5 and 6 in the image) are for self-level. Probably not the issue for not coming out of park although probably have a code or event of their own showing. If the boom and tilt are working...

    That was one of my first checks was fuel in oil. Noted fuel just shy of top of hash marks and no smell of fuel in oil. That was before I had gone back to do fuel filters so I’m sure the owner was cranking that thing like a mad man as he waited for me to get back the next night to throw those...
