Do Komatsu dozer parts fit both early and late models in the same series?

Many parts cross between early and late variants within the same series, such as the D65E, D65P, D65EX and D65PX, but not all of them do. Always check your serial number before ordering, because changes within a series can affect fitment. Matching the part number from your existing part is the most reliable way to confirm a fit.
