We are trying to fix our 4600's power steering. Ford no longer makes the power steering shaft/worm gear. SOOO, we are being forced to buy a whole new steering gear box assembly. Cannot find any for the 4600, but have found several on ebay for a 5610. Want to know, what is the difference between a 4600 and a 5610's power steering? We have watched a youtube video that a guy made showing him rebuilding his 5610's power steering, and it looks exactly the same as ours. So, what, if any, difference(s) are there between them?

Worm gear is toast, not sure it can be fixed? There's a lot of damage to the bottom part of the worm gear, as you can see in the pics.

Your tractor has the standard 8x2 trans with shifters coming out of the top of the trans, some models with different transmissions had the gear shifters mounted onto the sides of the steering column.

Tha 4600 All Purpose like yours has a straight axle, if you look at the axle it goes straight across the front.

4600SU has a sweepback axle design like ones on the 3600 models, these have a completely different steering setup and none of the steering parts will interchange between a 4600 and 4600SU.

A good machine shop can weld and refinish your old shaft, just the lower section where the seal rides is all that needs repaired.

Other wise I'd go with the conversion kit from Farmland Tractor Supply.

DA2 is a 4600 ag chassis model. Yours was made on October 25 1977. The parts site shows the power steeing gear to be the same part number as for the later 3 cylinder 4000, which is part number E1NN3N503AC.

Searching tractor-part.com for that part number shows that Cook Tractor Company in Clinton MO claims to have two of them in stock, one used an done rebuilt.

A photo of your tractor or the models numbers from the data tag under the hood would help us determine what you have.



Is this what you are talking about?

Can't find parts for our power steering anywhere. The worm gear is toast, that's what's wrong with ours. Ford quit making the 4600 power steering gearbox and everything associated with it, including the worm gear. We do not know why. We thought we found one from someone in KY from Cheap Tractor Parts, he had an ad on ebay that was wrong. He sold us a column that does not fit, the base is too small. And he doesn't have one for our 4600. SOOOO, we are waiting for the refund for what we paid, then start shopping all over again.

We may have to go this route. Turns out the guy we got the supposed re-man'd column from in Kentucky sent us the wrong column. SOOO, I am going to check out this conversion kit. How exactly does it work?

The kit from Farm Land Tractor is available directly from them or ebay.

I emailed them last week about one for my 5000.

This kit will work on tractors with loaders, the one you looked at on this site is a different kit.

Farm Lands kit works on 4000, 4600 and 4610 models, some 4610's had the gear shift levers mounted on the steering column, the kit must be modified for those models.

4600 all purpose tractor has a heavy duty straight front axle, the 4600SU series has a lighter duty swept back front axle like on a 2600-3600.

A photo of your tractor or the models numbers from the data tag under the hood would help us determine what you have.

Went to Farm Lands site, in the select equipment section I picked Ford/NH and 4600, then hit search.

The power steering kit was the first thing to come up.

Sorry for the multiple posts, but this site doesn't allow for editing, so...

Apparently the conversion kit IS on farmlandtractor.com. The ebay ad is from farmland tractor. What does it mean column shift? And it also says for STRAIGHT AXLES only. Does a 4600 have a straight axle?

I just checked this on yesterdaystractors.com, and it's NOT recommended for a tractor that has a front end loaders, which we have one. So, that won't work.
Will just have to get this sector from the guy on ebay. Not happy about how low he wants to pay us for the core, but oh well. Our tractor has already been down a month now. Can't wait any longer.[/quote]

Strange, I googled that part number you gave, and a couple links came up, one on ebay, and several on that Farmland tractor. Farm Land Tractor doesn't have it. I clicked all their links, nothing. I clicked the ebay link, and it took me to this :

https://www.ebay.com/itm/Power-Steering-Conversion-Kit-Ford-4600-2910-4630-4610-3910-4600-4000-5030-/302252551782

Another link took me to yesterdaystractor.com, then I had to search in their parts list for 4000 to see their conversion kit but it did not have the same part number:

https://www.yesterdaystractors.com/Ford-4000_Power-Steering-Conversion-Kit_FD100.html

Soo, I am fairly certain this kit is no longer made, unless it's the one on ebay....

$300 credit for the core is not bad for all the parts and labor that will go into it. Maybe the guy's kids need shoes.[/quote]

Considering there are 2 other sites that I have checked, and their cores are $650 and $750 respectively, $300 is nothing. The guy we are thinking of getting the sector from wants $400 for JUST the worm gear...which is MORE than what he wants for our entire core return. Outrageous if you ask me.

Before spending 1600 for a rebuilt gearbox, I would check out the company mentioned in Oregon that sells the full hydraulic conversion for 1500. That setup is much better.

We aren't going to do that. We are buying a re-manufactured power steering gearbox assembly this next week from a tractor place in Kentucky. It sucks to have to spend $1600 on it, but its better than having a $5000 tractor that won't run.

Hydrostatic steering uses a hydraulic orbital motor and a hydraulic cylinder to steer the tractor, newer 4630 models have hydrostatic steering.

Farm Land Tractor Parts offers a hydrostatic conversation kit that replaces the steering sector and uses hydraulic cylinder and modified drag link assembly that connects to the front axle.

Google: FD4600PSK, the kit cost around $1500 but that's less than a rebuilt mechanical sector.

They also offer a kit to replace the out dated PS on my old 5000, I plan to get one of those kits in the near future.

FYI, my 4000 had the side arm power steering, it is better than manual steering but is much slower then what you have, a few years ago I purchased a 3930 parts tractor and swapped the complete front axle assembly and steering column onto the 4000 updating it to modern hydrostatic steering.

There are aftermarket kits of the side arm power steering that are cheaper than the hydrostatic setup I mentioned but having owned a side arm setup I personally recommend not going that route.

skip that last message I wrote, I just found it on their site:

https://www.external_link.com/front-axle-and-steering/steering-sectors/e1nn3n503ac-rc-detail.html

But, I do not know what the RC stands for after the part number...it also says to call for price, which to me states, very very expensive. Will call them tomorrow. Thanks.

I just checked their website, they don't have anything that I am looking for for our 4600. Not even a complete steering sector. We won't be able to find the worm gear because Ford quit making it, it's 'obsolete'. And as far as i have been able to tell, by searching many different aftermarket parts sites that the worm gear isn't made by anyone else either.

Big ???, what IS hydrostatic steering? And is it like power steering? I was told by ultradog that we could convert our 4600's steering into the early 4000 side arm style....not sure what would be better?

Thanks for the help, we just found that out by looking at the same youtube video we were watching.
We are going to have to buy the entire power steering assembly. Got someone on ebay that has one, but he wants our core returned to them, and for $300 only. That doesn't add up...we don't know what to do.

4600-4610 drag link goes from the steering sector to the left steering knuckle.

5600-5610 drag link goes to a cross arm inside the bolster, this setup uses a reverse gear box.

If you install a 5610 gear box on a 4600 when you turn left the wheels will cut to the right, everything will be backwards.

Not cheap but Farm Land Parts in Oregon offers a conversion kit to change your tractor over to hydrostatic steering doing away with the troublesome steering sector.

We have found several new gearboxes on a few different sites that look exactly the same as ours, but are for 5610,6610,6610O,7610,7610O. We want to know what difference(s), IF ANY, is there between the 4600 and 5610's power steering? That was my initial question...

28 ball bearings on bottom, 15 ball bearings in the 2 races.
What we are looking for mainly is the power steering shaft/worm gear. The worm gear got trashed by some ball bearings that fell, and for some reason the piston would not move. We took the whole assembly apart, tried putting it back together, replacing the bearings where they are all supposed to go, and bam...the piston would not move. Pulled everything back apart, then when we pulled the worm gear out, there's damage on it.
We called the local Ford/NH dealer here, and the PN# E1NN3N966AA is the power steering shaft/worm gear that we need, but it is no longer made. Obsolete. We rather would replace this, than have to buy the entire assembly which is $1200-$2,000 depending on who has one available, and it wouldn't be a 4600 specific one. Would rather not spend that kind of money to fix this.

I tried to replace the top seal on mine since PS fluid was coming out from under the steering wheel. I had a problem with how to reinsert the 21 (I think) balls back in their normal position so that the wheel would turn an even number of turns both left and right. In missing one and working blind I trashed it. Local NH dealer located me a new complete box for $2k. Matter of fact, I still have the assembly, out in a junk pile.

Get a parts breakdown and give me an item number. Meanwhile I'll go out and look in my 4600 manual and go to the scrap pile and see if I can put 2+2 together. Come back!

In I&T Manual # FO-41, Page 15, Figure 19 is what mine had, single steering arm not one on each side of the tractor like lighter models. I think I have everything from P down the figure to the bottom, excluding 14, 15, and 16. Has been sitting out in the weather and steel has surface rust.

Any parts above that stayed with the tractor. Let me know if I can help.
