Kohler SV735 engine--Oil Drain tube loosened--how to tighten?

I have a Craftsman Mower with Kohler SV735 engine. When changing the oil, I accidentally loosened the Oil Drain tube. Given the way the engine sits to the frame, I cannot access the seat of the drain tube to retighten it adequately to prevent leakage when running.

Thanks for the inquiry about the engine model SV735, I will be glad to assist you.

Unfortunately I am not sure exactly where you are having a leak. There are three oil carrying tubes, the fill tube where you add oil and the feed tube that feeds oils to the filter and one that feeds from the filter. I cannot find a drain tube on this engine.

 

All of the tubes are sealed by O-rings and are just pressed into place.

If you could reply and identify the exact tube you are referring to I will be happy to respond.

 

A picture would be helpful.

If you get to the point where you need to have a service technician diagnose and repair this failure, you can schedule service through this link:

It's the drain tube at the base of the motor. I've tightened it as tight as I can by grabbing at the end with vise grips, I'd like to tighten more by grabbing the nut at its base signified by the red arrows in the attached pictures.

Hi Quinn, if you have tightened the drain tube and it still leaks, my sources tell me that you should try removing and cleaning or replacing the drain tube. Thanks for the image.

My question is not if my drain tube is damaged and leaking, but rather considering the design and the associated tight quarters, how does one tighten the drain valve? I see no way short of removing the engine from the frame, how to access the silver inner-most nut.

Hi Quinn, The plastic outer section comes off, turn lt. 4/4 turn then pull off. With the extension and cap out of the way you can tighten the metal drain tube using a deep well socket. (Tilt the engine to prevent oil from leaking while working on the tube.) My last reply about cleaning and replacing still applies if you want to stop the leak. You may want to try using Teflon tape on the threads.

Thanks. Just to clarify. The "plastic outer section" is the piece of plastic about 1.5" long? How do I get it off? Last time I turned it counterclockwise, and the entire drain valve came out and oil started rushing. Should I expect the oil to rush again? "4/4" meaning? Any suggestions on tilting the engine? Meaning dismantle engine from the frame and tilt 90 degrees?

Hello Quinn, I have located a link that should help you with this project, it has good images of the drain tube with suggestions and instructions for removal and even replacing. I do not suggest disconnecting the engin for this project, figure a way to tilt the tractor. There are other engin tip in this link but you can focus on the section about the drain plug tube.
