Combines Duetz oil leak

This is likely the orings at base of housing that has crank vent valve on it. Not to hard to unbolt, lift it up, and replace orings with OEM parts. Good luck

trent, you should only have to replace the o-ring----but my memory is failing fast. call the gentleman in oxford, he can give you some numbers to call. i don't want to post phone n's without permission.

I think you are working on the hydraulic oil cooler.Take the big plug out that faces the rear of the combine.Then take the top plug that has the leaking "o" ring out after noting the location of the themostat.There is a spring that will push the thermostat out when top screw is removed.Put a new "o" ring on the top screw,push thermostat back in against the spring,and then tighten top screw into locating slot in thermostat.If you just take top screw out and replace the ring the thermostat will shift to rear and hydraulic oil will bypass the cooler.Takes about 1_2 hour to overheat hydraulic oil.

I have the numbers of most of the Duetz people around here. Forest has suggested the people in Hendersonville before. They are good people, but they are tractor people, They have a book for this engine but I think is in Italian (no joke). I'm sure that all I have to replace is the o-ring my fear is that there is a trick to setting the spring tension or something will go flying when I take it off.

I'm working on the engine oil cooler. But that's good information. Thanks.

you may want to try goldsboro and _ or willamston as well. lots of combine experience there.

On engine oil cooler the thermostat just sits under the big plug.Gasket under plug is n1118835.
