LS MT3 57 - 50 hour service and filter issue

[Macinnis]

I received the following filters from my dealer (all of which are ls genuine parts)
oil - p/n 40409065
hydro - p/n 40347274
hydrostat - p/n 40007563

the hydrostatic filter would not go on. I call the dealer, they assure me I have the right part.

I try it again, no dice. I get the calipers out and sure enough, there is about 1/4” difference in the inside diameter of both hydrostatic filters (old to new).

I drive up to the dealership, she looks it up again and says there are two part numbers for that filter, the correct filter number for me was: 40383187, which is a Donaldson branded Duramax filter and it’s actual part number on the filter is P164381

by the way, you will need a device such as this to get the one filter off, it’s a monster to get off:

I hope this helps someone.

Funny, my dealer gave me the wrong hydrostatic filter as well. He didn't seem to know that there were two choices depending on the hydrostatic transmission. Mine also gave me the older hydraulic filter as well as they must not have the newer one on hand.
