Question -
I had volunteered last year to repair my neighbor's Toro 16575 Lawnmower, serial #: 7011607. The complaint at the time was that it wasn't running very well. This year it didn't even start. I replaced the spark plug, which was bad, took out the old gasoline, which was bad, and had to get in deeper than I wanted to. In taking the gas tank assembly off, I got a wire hook off, that I assume goes under the flywheel (?). There is a spring loaded thing that has a Z arm on it, but that is apparent where it goes. I am trying to prevent taking the inside top of the lawnmower off (I already have the recoil part off). Where does this hook attach to? The other end of this wire is attached to a T piece of metal that pivots with the hook. Any help appreciated.

Hi Michael,
Is the wire electrical or a part of a mechanical linkage?
If electrical, it might go to the coil under the flywheel but may be able to be re-attached without flywheel removal. (If you can see a blade connector.) Or to a safety kill switch near the flywheel or on the recoil assembly. If mechanical, it may go to the governor linkage arm.
Let me know what you find.

I found a parts layout on the Toro website; however, it is not as detailed as I would like. The item I am dealing with is a Link, Throttle. That piece has to hook on above the engine, but below the flywheel. I am guessing there should be some type of hole for it to hook in or something to attach to. Again, I am trying to do this without taking the flywheel off. I am afraid since I don't have torque tools, that when I take the flywheel off, I may not get it torqued properly, unless you just do the tighten it as tight as one can get it by hand.
Again, thanks for any insights into this.
Michael

Hi Michael,
It sounds like this is a linkage for the governor. I don't think you should need to remove the flywheel. If you can't find the hole and decide to remove the flywheel you can just tighten it tight with a 12" bar or ratchet.
Good Luck,
Michael
Here we go again; I put a light through the area under the flywheel and still can't see where it goes. I tried to take the flywheel off, but after I took the nut, washer and cup off, the top of the flywheel has a threaded round nut with a notch on one side and there is a piece of "T" metal that protudes into the nut to keep it from moving. I can't figure out how to get it out of there, and don't want to wreck it in the process. If it was my own lawnmowever, I would probably just take a screwdrive and drive and drive it down in. Any suggestions for getting this notch and nut out?

AnswerHi Michael,
Actually the bore of the flywheel isn't a nut. The flywheel is tapered and mates with the tapered crankshaft. The keyway in the flywheel and shaft keeps it from spinning on the shaft. The recommended way to remove a flywheel is to use a puller. An alternative, is to tap on the crankshaft top, with a brass hammer or use the round punch on an air hammer. The flywheel will need to be held up and supported or upward pressure applied with 2 large prybars. (A 2 person job.) Care is needed so the flywheel doesn't crack or bend. Also be careful to not mushroom over the crankshaft top.
Good Luck,
Michael
