ford model 1710 & ford 800
I have a ford 800 with a front-end loader with no power steering. As would be expected steering becomes more difficult when moving a full bucket of material w/o powersteering. However steering to the right is manageable but is a major challenge when turning to the left. So much that fatigue sets in when doing any amount of work. Even without any material in the bucket its still a handful. Anyone had any such experience or suggestions? Any input would be appreciated!

time to do some testing.

jack the front axle up so the tires can move freely.

steer the steering wheel from lock to lock.

look at the hub on the steering wheel and the steering column.. does the steering wheel hub rise out away from the column in one direction, and fall or screw in in another?

if so you have worn thrust bearings, which is a very common cause of hard steering one direction and easier in the other.

also.. observe the sector arms that come out of the sides of the steering box. when you turn the steer wheel, is there fore / aft movement ( or even up / down ) of the shaft BEFORE it starts rotational movement? if so, the sector bushings are worn, that usually doesn't make for hard steering, it just makes for sloppy steering, and makes it harder to adjust backlash out of the sector gears and ballnut.. also makes the sector seals wear and leak.

lastly.. lack of oil in the box will make it hard to steer.

next test is to see if you have excessive spindle bushing wear. go to the front knees and se if where the axle comes out of the bottom of the knee.. see if you can rock the axle inside the knee.. worn bushings allow the axle to cock to one side and bind.

depending on what you post back, you may need one or 2 thrust bearings and very likely the races.. .. plus bushings and seals if needed, and if spindle bushings worn.. them too.. check front hubs to see if they have any play while you are at it.. IE.. front wheel bearings and seals. also check rear draglink ends and front tie rod ends.. botht he pin and the dust seal... those also add to slop.. but not so much hard steering. worn front wheel beaqirngs can lead to wobbly steering and hard to set toe in when travveling.

a 32oz tube of NLGI EP 0 or 00 grease can then be used to refill the box after you rebuild it, set preload with shims and adjust backlash via sector adjuster studs.

there is also a lil bushing/bearing that sets at the top of the steering column that usually needs to be knocked out and replaced.

I generally plan on rebuilding the steering box on all my manual steering fords when i get them. price is less than 100$ in parts assuming no gear wear beyond reusing the ballnut/worm gear, double and single sectors.

an impact wrench will be helpfull in removing the acorn nut atop the steering wheel, plus the sector arm nuts. a 2 jaw tie rod puller is good for removeing the pittman arms from the sector shafts.

for the steering wheel.. be carefull.. a 3 jaw standard puller usually mangles the hub.. I use a 2 jaw that is a wide narrow jaw .. it is more suited for pulling wheels.. there are also pullers that pull on the spokes. in rare cases you have to split the hubs of the steering wheels to remove them.

I just finished rebuildig the box on my 63 2000.. ie.. same box as your 800. if all the nuts and bolts and arms and steering wheel come off with no more than usual hassle, figure that you can pull the hood sides and set them aside a lil, and then the dash.. etc.. pop the box apart , and preferably seperate from the tractor and rebuild ont he bench... probably use an hour to get it free of the tractor.. then an hour to rehab, and 30 minutes to set back up on the tractor and adjust and be ready to go after greasing... if you've worked on em before.. or had the hood off recently and them lil fasteners are new or neverseized.. haldf the times I mentioned... someone who knows a ford can usually rehab and have a box back together on and off the tracor in just over an hour.

post back with any questions... ford manual steering boxes are EZ.

ps.. I'd suggest having the fo-20 service manual handy for retiming the sector gears to the ballnut.. there's a cheating method.. but best if you learn the correct way.. ;)

Thank you so much! Sounds like a thorough test of the steering components. Your instructions sounds easy enough to work through. You make the repairs sound simple. I have a IT repair manual that I glanced through the section on steering boxes. I found it somewhat intimitating having never worked on one but you make it so simple. I'm looking forward to trouble shooting as you suggested. However the tractor is at our vacation home a couple hours away and I wont have the opportunity to get back up there in the immediate future.
I will definately get back to you with my sesults. Thanks again so much!

I suggest you print out my message and take it with you.

I'll also include in this post an exploded diagram from the NH parts site as well as a parts listing to go with it so you can 'see' the innards and know what to expect.

whenever you do go and do the tests.. just make a new post in the ford section.. someone will see it.. there are at least a few other guys here that know these fords in and out.

what follows will be the parts lists for the steering box and the frot axle .. as well as 2 pics showing the front axle and box, in exploded format, with parts numbers matching the lists.

good luck, and post back. steering boxes are easy to R&R.. we can help you..

Great. You have been so helpful! I have printed everything you've sent me. I'm so anxious check it out! Once I have diagnosed it and feel confident of my asessment it may be a while before I get time to tear it apart as I use it quite a bit at our vacation property and don't want to be without it for any length of time. When I have a decent window of time available to complete the job I'll get on with it. I'm sure it will take me a bit more time than you, it being my first.
Thanks again!!!

Will do a new post after my trouble shooting as you suggest.

even with a learning curve, this is a 'lunch' job.

IE.. start at breakfast.. loosen hood tin so you can get at box and box top.. get gauges out of the way.. yadayada.. battery..e tc.. then seperate pittman arms from sector shafts.. then pull 4 bolts.. etc... etc.

OR you can work on it right ont he tractor if you have shade.

depending on what it needs.. sector arms may not have to come all the way out.. can pull side covers and slide them in enough to clear ballnut, if it's lower bearing is bad.. usually if there is oil.. it ain't.

in some cases.. it's merely the top bearing.. and if you can fish the rollers out with a magnet on a telescoping stick.. then reallyit is just pulling the top of the steering column off after getting some tin out of the way, remove old bearing.. slide new one on, adjust shims and rebolt cover.. and then adjsut sector backlash. IE.. 2hr job.. remember to relube the box. I like 00 EP grease.. you can get that at many places that sell lawn equipment.. or jd cornhead 0 ep grease will work.

Would like to clarify a few things: Where you say the sector arms may not have to come all the way out. Pull side covers and slide them in enough to clear ballnut. What cide covers and ballnut are you referring to? Part # 1 "cover assy"? Plus I don't see a ballnut listed!
Also you refer to oir & grease in the steering box! I couldn't find anywhere to put oil in it but it has a greese fitting. I assumed it only gets grease. Am I missing something here? I filled it with grease until it wouldn't take anymore. However now I have noticed grease leaking out from the right side sector shaft seal.
I'm assuming the hood pannels must be removed. That is quite a challenge and almost requires two people since it has a front end loader due to the close clearance of some apparatus which easly scratches the hood pannels that I had repainted. Even with two people it requires extreme patience and care. Although not impossible.
I'm working in a spacious garage so the concern for shade is not an issue. If it is possible to repair on the tractor,that sounds like my prefference.Unless you highly advise otherwise.
Back to the pert that I mentioned the right sector seal leaking grease I would assume that is an issue that would require replacing the seal and most likely the bearing being the cause. Your opinion?
And thanks again so much for your time and advise. And of course your patience with my inexperience.

there are only 2 'side' covers on theis box.. right side and left side.. they are part number 1 on the exploded diagram.. they are oval and the sector adjuster stud sticks out of them, held there with a locknut.. those covers have to come off to slide the sector gears out of the box.. however.. you don't have to slide the gears all the way out if you are only servicing the lower bearing on the steering worm shaft. just the double sector must be slid out enough so the ballnut that rides the wormshaft can clear and the shaft assy be lifted out.

the ballnut is a part of the steering wormshaft assy. there are no individual parts available for it, so no part numbers are listed for the recirculating ballnut.. that's the squarish piece with grooves on it that rides the lower 6" of the steering shaft worm gear.. as you turn the steering wheel, and thus the steering shaft, the ballnut must rise or fall as the shaft is screwed thru the middle of it, and it is engaged via gear teeth to the forward double sector, which is in turn engaged by gear teeth to the aft single sector.

originally the box top.. the part with the steering column, had a plug in the top of the cast iron cover. someone has removed the plug and installed a grease fitting in it's place. Originally the box was an oil sump holding gear oil. back in 62 ford put out a bulletin to instead fill the box with NLGI 0 EP grease to combat leaking sector seals. It is NOT adviseable to put in greular 'gun' or NLGI 2/4 chassis grease.. it will make a cavity around the gears and ballnut and not slump, and very soom the gears will be dry and unlubed again.. same with the bearings. Only NLGI 0 or 00 ep grease should be used. it is a semi-liquid grease that flows and slumps, and will refill the cavity made during steering.

If you have worn sector seals it is common for grease or oil to extrude / weep out of the sector seals.

there are no sector bearings, only sector busings. the more wear the seals and bushings have, the more it leaks. in general, if the seals are not hogged out, they usually hold grease ok. if the bushings are bad so that the sector arms have for / aft movement before starting rotational movement.. then IMHO.. they should be knocked out and replaced, and the seals too, and I'd still use the 0 or 00 grease and not oil.. but under no circumstances #2 or #4 grease.. I don't think I would even use #1 grease either.. simply too stiff...

the shet metal setup on that style of tractor is as follows:

dash, has steering column and throttle rod thru it...

dash cowling. this is what the dash bolts to as well as the hood side pieces.

hood panels. there is a left and right hood 'torpedo' panel that bolts to the cowling on either side and thent he dash sets on top and bolts to both the cowling and the hood side pieces... left hood side piece holds the hinged part of the hood, right side piece has the latches.

at a bare minimum, you must remove the DASH piece. you remove the steering wheel, and disconnect the oil line, proofmeter and the ammeter connections after of course, removing battery cables. it is adviseable to remove the throttle rod, but you can get by without doing that or removing the temp gauge. there is enough play in the temp gauge cap tube to let you manipulate the dash with it in place. you then slip the dash up over the steering shaft and then angle to the right and slide it over the throttle rod, with the throttle rod aimed out to the far right. set dash up on gas tank... at this point, if needed, you could use a ratchet and extension, and unbolt the 4 bolts holding the steering column / box top on, as well as unbolt the 2 side bolts that go thru the dash COWLING and into the steering box column brackets.. the dash cowling will slump a bit .. then you could lift the column off to replace the top bearing as well as the column bushing. you COULD leave the hood side panels and cowling setting where they are.

note, the wireing connection points and regualtor are nestled rightup there on the column, and those will have to be dealt with if still in place.

if you are pulling the wormshaft to repalce the lower bearing, then you will need to remov ethe side covers and slip the forward sectro out so the wormshft clears.. at that point you could remove both side covers to service bushings and seals if needed, leaving the sector arms setting just inside the edges of the steering box cavity.

a 2 jaw pittman arm puller is very usefull for pulling the sector arms off the sector shaft. the shafts have a master spline so the arms are easy to get back on in the same orientation they came off.

depending on the obstructions and room, and tolerance for fighting with metal,and other variables.. you can do the box on the tractor or off. I usually leave them on the tractor unless repalcing the lower bearing race, in which you pretty much MUST remove the box.

my last box job I didn't feel like dinking with it in the sun so removed it to work on on my shop bench.. though certaintly could have worked on it on the tractor if needed.

if you are worried about scratching pain, put wide 2" masking tape alon and around bolt surfaces so in case tools slip off bolts they don't mar the finish, and mask or tape newspaper or masking paper to the parts that will be unbolted but left in place, so thet there is a layer of paper between say.. the hood metal and the loader posts..

i usually don't worry about that as i do my repairs before any painting..e tc.

that's about it in a nutshell.. ford ag model steering repair 101 1948-1964, and a couple others till they changed the box a lil with some sector retainers under the covers, and ov course the row crop single arm boxes.

not much else I can do other than turn the wrenches for ya.

Would like to clarify a few things: Where you say the sector arms may not have to come all the way out. Pull side covers and slide them in enough to clear ballnut. What cide covers and ballnut are you referring to? Part # 1 "cover assy"? Plus I don't see a ballnut listed!
Also you refer to oir & grease in the steering box! I couldn't find anywhere to put oil in it but it has a greese fitting. I assumed it only gets grease. Am I missing something here? I filled it with grease until it wouldn't take anymore. However now I have noticed grease leaking out from the right side sector shaft seal.
I'm assuming the hood pannels must be removed. That is quite a challenge and almost requires two people since it has a front end loader due to the close clearance of some apparatus which easly scratches the hood pannels that I had repainted. Even with two people it requires extreme patience and care. Although not impossible.
I'm working in a spacious garage so the concern for shade is not an issue. If it is possible to repair on the tractor,that sounds like my prefference.Unless you highly advise otherwise.
