onan 16 twin starter not working below 20'f

Recommended Posts

I thought one of you motor heads out there could give me a clue why the starter on my onan 16 horse twin won't turn in weather colder then 20' If I warm up the starter with a blow dryer, it will turn begrudgingly and once warm will work the rest of the day, until it cools off again. As the cold air is bothering Kent's (of simple tractors fame) hand any help getting started more quickly will be applied directly to kent's driveway.... thanks in advance! regards jim.

Hi agree with Ken, but also you might have a case the starter frosting up. In others words a frozen starter from condensation inside of it. I would disasemble the started and used a type of "tuner cleaner" and spray it clean. And then do as Ken suggested. One more thing you may just find that one of the magnets has either cracked or is loose inside. I have found all of these problems along with what Ken mentioned to be either the problem or problems. Check all conections and out put of your battery while your at it. I hope this helps and its not a magnet that has let loose inside. Best of luck->happyjack<-

These starters have scintered metal permanent magnet fields which are subject to cracking..they're somewhat fragile. You might strap a voltmeter on your battery while cranking the engine. If the voltage drops below 10-10.5 volts check the battery as well. Certainly the advice offered above is correct. As for grease I prefer the white Lithium type. By the way, the fields are not serviced seperately by Onan..if they're broken you're in for a new starter.

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
