For those of you who own a diesel pusher with a CAT engine, there is a new (somewhat) group on Yahoo called "CATRVCLUB". There is a rep from CAT who will answer or find the answeres to your questions.
The link is http://groups.yahoo.com/group/CATRVCLUB
They also have in the files section, specs on the 3126, C7, C9, C12 & C15 engines, along with the information on how to check the valve lashing and make the adjustment. Enjoy.
