Fert Dust & Vanguard 16 hp motor

To whom it may concern.
I took both of my Z's to the shop AGAIN for a stator gone bad. One little spot of fert stuck to one of the copper coils and its just a matter of time before its shot. One has been fixed already last week. I took the second one in today.

Possible fix.

My mechanic has hired a retired gentleman that spent years rewinding electric motors. He said that when these type parts/motors are wound the bare wires are treated with a basic varnish of some type mainly to protect it from atmospheric conditions. He has found a high strength, chemical resistant varnish to apply to the copper wires and is going to apply at least a couple of coats to the bare wires on a new stator and it will be installed. Hopefully it will last longer than 4 months like the last few I've had installed. We will see.

Just thought some of you might be interested

That's strange. Wire coils are always coated in some kind of varnish, treated paper, tar or plastisol. If it isn't your mechanic should have picked up on that the first time.

I've asked him about spray painting them or applying some type of spray on bed liner material. He has told me that was not possible.., the wires have to remain pretty much exposed to work properly.

The retired gentleman also said that he will have to tape off each of the outside conductors on each of the coils around the stator so they don't get anything on them while applying the industrial varnish or it won't work properly. He said there is a coating on the stators from the factory, it's just not designed to repel fert induced corrosion. He also said there is a fine line between too much and just enough when coating them. Hell, I don't know. I'm just a "MacGyver" I'm not a mechanic or an electrician. I leave that work to the experts.

You would think B&S would have something... An HD Stator or something.

....I can't be the only one who has had this problem.

I guess this is not overload by using sprayer correct?

Not sure what you mean by "using sprayer correct" and "overload"??? I know how to use a boom sprayer set up on a zero turn platform ...I do have an auxillary tank that I use on only one of the units and it is never operated simultaneously with the factory sprayer so if that's what you mean by overload??...but to answer your question no, I have seen all stators after they have been removed.

It is very obvious that the motor sucks in fert dust and some of it ends up under the flywheel on the stator. The wires will have turquoise pockmarks. Some have been in worse condition than others but as it was explained to me, "It takes only one strand of wire on only one of the coils to be compromised with corrosion and the whole part is toast".

I'm not even going to go into the fert that I used all last year...

I gave up. I can't afford to keep replacing stators. Not only the mechanic bill, parts, etc. but the dang downtime.

I just wired up a deep cycle battery and I charge it each day. Only thing I know to do.

My only complaint about the Z. Something needs to be done. It's BS.

think it would help to take a blow gun and blow the engine off at the end of the day?

I do, and it does. I do the best I can with it but its just not practical for me to take the tank off, then the motor cover to reach the deepest recesses of the motor on a daily basis.

I have a fine tipped gun for the compressed air and believe me, I stick it in every little hole I can find on the outside of that motor...

I'm also looking in to a steam cleaner to go over it and thoroughly clean it. I'm not sure that this will help underneath the flywheel though.

Won't help under the flywheel and you really don't want it under there. Steam is a good idea for getting the chems off the rest of the machine though. Anything that can remove the caustic stuff from surfaces is bound to help. I'm watching a shos right now that is talking about new products from wd 40. They have a thin protectant lubricant spray that doesn't let grit stick to it. Sounds very useful for our equipment and conditions.
