I have two cases of Fleetguard oil filters for a OM636, these are LF695. They are for use on generator and refrigirant engines. Thread size .75-20, OD 4.235, length 6.64. Standard equip on ThermoKing reefers also. LMK if you need them, I am thinking $50 for twelve shipped. Pretty good price, retail is $14,99 each. Thanks!

BTW: I have one factory sealed case of twelve and the other case was open on my shelf. All the filters are still sealed.

Not sure if these work on the marine or Unimog versions of this engine.
