Hey guys. I've had issues with my 54" auto connect deck disconnecting for quite a while. Sometimes it won't come off and I just give up. I've read other threads about similar issues and tried the suggestions. But one thing that I'm wondering about is the set screw in the male end of the deck side gear case. It appears from what I've read here, and what I can find for parts diagrams, that there should be 2 set screws. If you can tell in the pic, on mine it looks like there's 1 set screw and 1 pin of some sort. Is that right, or did the set screw back out and get smashed sort of flat? Any insight would be appreciated.

Thanks!
Steve

Doesn't look right to me. The parts diagram for the auto connect only shows two set screws (part 22M7072, M6 X 10). Having it protrude like that could certainly cause it to bind up.

I'd pull it and replace it.

That's the diagram I looked at too. I guess I might need to figure out a way to get it out. The screw must have backed out a long way to get smashed like that!

thanks

Have you got a good hardware store or know where a Snap-on or Mac tool truck stops? A small, left handed drill bit would probably start to drill in to it then grab it and spin it out...


Good Luck.

Looks like it is protruding a little. If enough is sticking up to grab it with a needle nose vise grip you might be able to lock down on it and unscrew it otherwise like AJgrn78 said drill it and use an extractor. Good luck let us know how you make out. :good2:

I would take a small stiff stainless wire brush and clean it totally and then take a look at what I have before running to a metal drill bit and easy out. Drill bits tend to drift, bend, flex etc and can mess up the threads even if you prick with a machinist punch, it's a last resort. Brush it real well. Use dental pics around the circumference of the screw to and clean it again. If it has been mushroomed because it backed out, you could gently use a small flat punch and tamp it laterally. I've done this and have gotten just enough to get a bite with vise grips and turn it out. Have been real carefull so vise grips don't squeeze and break off the tempered metal that was the product of the fault(mushrooming and laterall punching) it becomes brittle. Also, after dental picking the circumference, use a very good penetrating oil and shock the casing with gentel tamps from a piece of brass dowel and a tack hammer. You could also cut a slot and try a driver.

If that doesn't work, carefully machine down the mushroomed head(file, dermel etc) than prick it center and drill it with a real good NEW small pilot bit. Don't go thru the plug if it's not shallow. Increase the size of the bit till you can get a bite with an easy out. I've ground the tip off easy outs so I can blind seat it. If that doesn't work, increase bit size in steps, don't hit the thread and weaken the ring that's left of the set screw.

When you get it removed clean the male and female threads of the coupler and new set screws with brake cleaner and let dry, then use a low strength Loctite when you re assemble. If you ever need to get it apart again heating to about 300 F will liquefy the Loctite and allow removal. These set screws are subject to ungodly vibration.

Yup.. Set screw backed out. Those lil screws are hard hard metal. IF you can get it out, great. If I were you, I would pull the gearbox off and take it to an automotive machine shop. Let them get it out. You'll be money and time ahead. Worse case.. They can drill and tap a new hole for another set screw.
I've seen this multiple times. I have sent in reports to Deere suggesting loc tite on screws. I put it on anyway.

or try the lazy method... if you have a dremel try carefully putting a groove on the end of it and maybe it will turn out with a flat head screwdriver, I don't think it would matter if you accidentally hit the shaft just a little

Use a grinding wheel on your Dremel and you should be able to put a nice groove .

All great suggestions guys, thanks. It's got to come out so I will hopefully get a chance at it this weekend. Of course my warranty just ran out in mid April lol! How it goes I guess.

I'm guessing if you loosen the other set screw and removed the piece from mower, then take it to your dealer they would remove the damaged set screw for you at no charge.:dunno:

The screw came right out with some needle nose pliers. As you can see from the pic there wasn't much left of it. Replaced it and used loctite on both of them so hopefully they will stay put. Deck snapped right on, which it didn't before so hopefully these problems are behind me. Thanks for all the help!

Gotta love needle nose pliers! :good2: Good work.

That set screw must come out. Hit it with some PB Blaster or equivalent, let it soak, and get on it with a left hand drill bit, or an extractor. It should be replaced before you try attaching again. It will come out--just be patient. Good luck.

I had the same problem detaching my 54" deck a couple weeks ago. Thought it was just a dry PTO connector. So a little fluid film and all was good. Then I stumble on what you guys have experience and sure enough I checked and had one set screw loose and the top scrubbed off. Was loose and a small flat screwdriver took it right out. Bought two today, good to have an extra. And tomorrow I will replace it with a touch of Loctite. Thanks guys, again. For all the info.
