I just spent some time on Bill's site comparing the part numbers between 4540 and 5155 filters. The inner and outer air filters do cross over, they are the same. Engine oil, hydraulic suction, and fuel filter/water separator are all different. No hydraulic strainer is listed for the 5155, nor a secondary fuel filter element. As previously stated by another, the 5155 does have a hydraulic strainer, just in a different location. Correct? Also, does the 5155 have just the one fuel filter instead of the dual filter setup on the 4500 series? Maybe one of you 5100 series owners can chime in.
I agree with you, DaBear. The 5155 seems to retain all of the features that I love about the 4540 (heavily constructed, strong lift capacities, ect), and a fix for all of the downsides that I dislike (primarily the transmission).
