How do you choose a CAT filter?
Choose the filter whose reference and application are confirmed for your machine serial number. CAT 320D alone is insufficient: our catalogue distinguishes oil filter 1R-0716 from fuel/water-separator filter 227-2380. They serve different functions; the list does not prove compatibility with every variant.
C6.4 vs C6.6: how do you verify parts?
The C6.4 and C6.6 codes do not establish part interchangeability. Record the full engine model, serial number and removed-part reference. Cat resources distinguish equipment families and request serial identification for parts searches; that identification matters more than a similar model name.
