I've had no issues getting parts for my 3126B from the Cat dealer. If they don't have what I need in stock, they usually get it in a day or two. Although my engine has been reliable, I've done a lot of preventative maintenance over the past year since we bought it.
No concerns at all, I love my Cat engine. Definitely recommend them.
