subvet720 179 #1 Posted October 26, 2022 (edited) When I purchased my WH 310-8, the oil level switch had been disconnected, and after removing the oil pan, I discovered that there were broken pieces of the switch in the bottom of the engine. Being compulsive as I am, I had to fix the switch. The Kohler part # 15 099 02-S is available, but is pricey. The company that originally manufactured them (Gemtech International) is now part of Tyco, and they no longer manufacture the needed version of the switch. I did find that a Madison M7700 has all the right specifications, and have one on order. The cost was $22 on Amazon, and I am hoping that my mighty Conrad Weiser Wheel Horse will have a functioning float switch and test switch by the weekend. I will post an update when I get the switch.

WHX?? 48,815 #2 Posted October 26, 2022 (edited) A M12 I have in a repoed C-120 has one that was never connected. I won't connect it ... one of my few good habits is checking oil. I should pull it and give it to someone but have no idea how to get it out without breaking it. Would almost have to pull the motor? Are the threads NPT to plug the hole?

I had to remove the oil pan to see what was left of mine, but that is not a big job. The thread is 1/2-14 NPT, so it should fit. I just need to see how the switch works and may have to rotate the switch 180 degrees depending if it is NC or NO. The first thing I do when before I start any engine is check the oil, so the switch is not required, but my obsessive/compulsive voice tells me that if it there, it needs to work. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,041 #4 Posted October 26, 2022 The switch can be removed from the engine without damage following the instructions in this service bulletin 2 Share this post Link to post Share on other sites
WHX?? 48,815 #5 Posted October 26, 2022 (edited) Thanks Garry... I think the procedure is in the magnum manual too. 11 minutes ago, subvet720 said: my obsessive/compulsive voice tells me that if it there, it needs to work. I hear you there... actually I think I picked up that in my bubble head days... I gave up on safety switches on tractors tho.

biged77 113 #6 Posted October 26, 2022 After reading the "Important Note" in the service bulletin about potential interference between the oil dipper and oil level switch, I decided to not reinstall the switch when I rebuilt my M10. I expect I am not alone. This interference may be why your switch was in pieces. I already gave my switch away to another RS member or I would send it to you. 2 Share this post Link to post Share on other sites
subvet720 179 #7 Posted October 27, 2022 After a little further investigation, mostly because I can't leave well enough alone, I have a stainless steel switch coming Friday. Hand crafted in China to exacting precision & detail, it set me back $9. By the time I have completed with this obsessive compulsive effort, I will have the best monitored oil on the planet A good submarine Torpedoman never lets an indicator light go un-used. 3 Share this post Link to post Share on other sites

subvet720 179 #9 Posted October 27, 2022 (edited) That we are The Navy even disbanded TMs a few years ago and made them MMs. They came to their senses and brought them back though. Edited October 27, 2022 by subvet720 1 Share this post Link to post Share on other sites

subvet720 179 #12 Posted October 28, 2022 The Madison M7700 switch works like a charm. Unfortunately, although the SS switch looks cooler, it required too much room to activate and it won't work. I also disconnected the switch from the relay for the starter so that the tractor will start without the switch circuit, and I will make a mini harness to just activate the LED (replaced the incandescent bulb) if the oil goes low. I will also incorporate the test switch just because I like to make the LED light up without draining the oil. Makes me feel powerful 1 1 Share this post Link to post Share on other sites
