Early 8n steering box overhaul

pixer · Nov 25, 2017

If I buy a steering box overhaul kit for my 47 8n 4 bolt steering box and replace all parts that come with it will it take out the excessive play my
steering has in it?. I have tried turning the tight sector clockwise and turning left sector the opposite, this only made it harder to the wheel but
still has the play? Thanks in advance

That's the general idea.

I wasn't aware that any one was making replacement sector gears for the 4 bolt box. The worm and shaft is about $300, as I recall. Maybe all it needs is a worm, bushings or bearings and races. But you won't know until you get in there.

I have 3 early boxes apart to be rebuilt . I have all of the parts and built a tool on the lathe to drive in/out the bushings and seals .

I have noticed that my gears and shafts mic'd out good , but the cast iron sectors are slightly hour glass shaped from decades of force .

The new bushings are tight in the center but looser on the ends . I don't think it is worth it in my case to bore the sector housings and make custom bushings .

My shafts , balls , and blocks are in good shape so new bearings and good maintenance should be good enough .

I really like the O'Reilly brand synthetic 85-90wt gear oil . It is almost clear and would give a good visual if it is contaminated or dirty . It looks like Karo / Corn Syrup .

If you are spending a lot of money on your tractor to make it top notch , get you a later model two bolt box . For an average working tractor the four bolt would be fine .

about the only thing you can't fix in a kit is if the sector teeth on the ballnut get worn to a point.. or the sector gears themselves.
