Most every repair is different. You must "first" find and repair what "caused" the need for what you are repairing. For example. You can keep replacing a spark plug that keeps carboning up, but to repair the "cause", it could simply be a dirty air filter, or as bad as a collapsed oil ring or scored cylinder.
Randy, It sounds like you are looking for allowed standard hours for repair of specific tasks a la automotive data base? I can't remember what they are called. I do not know if such a "bible" exists for tractors, but I would expect yes, especially for factory authorized outlets. :anyone:
