Sloppy Steering on the 520's? Any ideas?

[HorseFixer 2,012]

One question, I understood ( or misunderstood) that the block that needed to be milled was no.47 in the photo of parts? This is the piece with the shim under it. You were sanding the bottom of no.19?

Hi Denver, Duke ended up sanding down part #19. Matt had #47 milled down. #47 supposedly comes from the factory with 3 shims #46 I believe. The shims can be removed to take out some of the slack. Matt's issue was the shims had already been removed which is why he milled it down.

Malmac1 pointed out that milling #47 will cause #15 to sit higher at one end. He said the change in the angle reduces the area of gear mesh and creates more wear in the future.

10-dash 4 Pipes!! Exactly Milling or taking material off the top of #47 Raises the fan gear up but ***** it out of

alignment making the teeth of the spur gear and the fan gear not mesh correctly preventing them to not use all

their surface area to distribute the load. This will cause the teeth to wear uneven and have premature failure. Thats why I am

milling /sanding the bottom of #19 lowers the spur gear down on the fan gear without throwing things all out of alignment.

Pipes is correct mine has 3 shims and they will go back in there too! I don't doubt someone has taken the shims

out of Matt's tractor already, and that may have Bucked up his TEETH! Pipes missing the shims would in essence do

the same thing and raise it milling it would raise and cock it even further out, not correct it.

Duke, that is great video on "How to" for the steering. I appreciate you taking the time to do that.

Your welcome! Denver a picture is worth a thousand words, in this case a movie. Ill try anything once! We will

soon see whether my theory is correct or not? when I make the final cut (movie) and its all together hopefully It

will have much less play in the steering. Thats what I'm hoping anyways.

Take care ~Duke

I understand how the geometry changes by milling the under side piece.

I will be watching for the next sequel to the movie.

Thanks again. Denver

Duke your vidio was great and right on the money, and The 520's with a gear reduction steering will have free play in the steering with all new parts. remember that this is a tractor and not a car that goes 70+ mph, You go 10-14mph max. You have a small amount of play between part#s 12 and 15, also 15 and 49, 49 and 46, and 46 and 25. That's 4 spots that will have some play in them and it will be felt at the wheel. You can adjust some of the parts to take up some of the play, but there will still be more play then a standard steering system on the older tractors. The reason for the gear reduction is to make it steer easy. You can put the non gear reduction on the newer 520's and the play will ge gone. And I do have one if someone wants it, but it will steer harder. this is my :dunno:

Hey Duke, I have a couple of questions for you about part # 6472 (bearing-flanged). I saw you with it in the 520 video and remembered you added one to your 417 to support the steering shaft at the dash tower.

Does the inner circular piece oscillate or pivot?

For example if you bolted the flange part to the floor and placed a piece of round bar stock in the center-hole so it was vertical and 90 degrees to the floor, would the bar be able to pivot to say 70 degrees in any direction?

If so, is there a groove or something with ball bearings or is it like a ball valve.

Is there a set screw or maybe a tapping for a grease zerk in it or am I seeing things?

Thanks for any info you can offer.

I have done most of all the hard and most expensive stuff like the walls and all new cabinets a few years ago. Im now intalling new floors (have to tear out the old down to the decking) and adding a dish washer (never had one) and all new lighting. All of the cabinets I hand made my self, with the exception of the raised panel doors. I ordered those. I;ll be watching for the video.

YES

It's a cheap azz stamped Steel To Steel Thing No Balls To It.

If I would have to compare more like a ball Valve

Is there a set screw or maybe a tapping for a grease zerk in it or am I seeing things?

Yer Seeing Things, Ill Get better pics on Next Movie 4 you.

The best way to lube would be to use Spray Grease. With a straw on can

Thanks for any info you can offer.

Yer Welcome! ~Duke Over N Out

Great video Duke and congrats on your success. As soon as I get more time I'll be doing the same. One question - is the steering still easy or does it feel stiffer?

I have to order a new block bearing from toro because I let a buddy with a mill grind off another 020" but he mistakenly ground off 0.1" so that block is toast .

Thanks Matt, as I said in the Vid you were onto something. I still personally wouldn't mill the block I think yer

better off taking it off the bottom of #19. Now how I would determine how much to take off # 19 would be to have it all

together (shims out) and tight and then use some feeler gauges of some sort Wire Type? Maybe get some small pieces of

music wire Mic & lable them with masking tape, and stick them between the teeth and determine how much should be taken

off. If you go a little over like I did, dont worry about it, shim the the bottom block thats what those shims are for now dont

use no 1/6th inch .0625 shims but I think 1 to 30 thousandths is okay Malmac is right throwing that block too much outa kilter

will throw off the alignement of the fan gear with the pinion like I said determine what you would take off to get ot tight and

then go .010 over that. I might go out in the garage today and remove 1 more shim and will Mic them If I gain anymore

significant Improvement I will post it here.

Steering Easy you ask? Smooth as Fricking Silk!!!

Remember If it aint tight it aint right!

Goodluck with yers ~Duke :party:

Job well done Duke. Thanks for taking the time to video this and show first hand what it akes to make it right!

Yer welcome, I'm glad I could do it and why not? Mines all apart and its was perfect timeing. Now I feel confident that I can get some play outta my 417A but only

wish I coulda done it when I had engine off. :cry:I did do the flange bearing at the steering wheel this spring but still have some play down below. Damn engines in the way now! gonna make it rougher...

Happy Shimming! ~Duke

[mattd860 161]

I finished tightening up the steering and im very happy with the outcome. Check out the video below. Its not HorseFixer production but I think it explains what I did.

Looks good Matt looks like you got everything taken care of and nice video!

[mattd860 161]

I also want to add that driving the 520h is now a pleasure! Before it was actually a burden.

[HorseFixer 2,012]

It dont gotta be a HorseFixer production to get the Job Done! Looks good

Matthew hey we all learn together, usually If I can see the problem I can work out a

Solution even if it takes several attempts It allways is nice to have a couple guys

working on the same problem to help compare notes. What one guy wont think of the other

one will!

Does anyone know a source for gear reduction steering parts besides used?

You might have a better chance of finding a unicorn.  There might be some new, old stock parts somewhere, but I doubt it.

[Bill D 1,596]

Contact @AMC RULES.  He had a picture in Stevebo's meet and greet thread with a picture of a GT 1848 that someone had swapped a 520 steering gear in.  He indicated that it was for sale in the post.  If you're looking for parts, that's probably your best bet.

Hydro trans too, or just the steering?
