I had a leak under the dash and saw it was coming from the steering motor or steering box. I replaced the seal on the shaft and the mylar or thin foil gaskets and put it back together. Now steers real hard plus it still leaks. We took it out again and one of the gaskets was damaged. The leak is fixed but it still doesn't steer an better. We made sure hydraulic lines going to steering motor are correct. We then took apart the steering valve and the spool was scored and didn't move easy in the valve body. Got er polished up and so now it moves nicely. But it made no difference. It still steers hard. It steers easier when not running. Any ideas? |

If those are the same as a 4430, we had that happen too. It's not as simple as replacing parts, when you put it together you have to hang a weight to the steering wheel or something like that to get everything set right inside there. We ended up having to take the whole steering set up and steering wheel to John Deere to do it for us. If you have the newer style steering box and yours is shot, we have one sitting in our barn. John Deere told us we could update it and just bolt it in, they were wrong. We were out about 700 bucks thanks to them.

Do you mean all the stuff in the steering column from the wheel to the box has to be just right or it won’t work?

Yes, when we first changed the seals like you did, it did the same thing. We then took it to a backyard mechanic, the steering valve and column, but not the steering wheel as we didn't know he would need it. He tried to set it but when we put it back in, the wheels would go full turn one way (can't remember which way but that doesn't matter), that's when we talked to a JD mechanic who said you put the whole works into a vise and hang a certain amount of weight on the steering wheel when it's turned full one way. Seems like a goofy set up but that's what it needs. I don't have a clue as to how to set it, sorry.

Wow. Sounds complicated. I have a former JD mechanic looking at it. He says he’s done them before. Never had an issue until now.
Thanks for the info.

Yes it is weird. If for whatever reason you need to replace it and have the newer style, I can give you a good deal on the old one we have.

 Yours must be different than mine.

Sorry, maybe it was, I can't remember exactly what it looked like, has been a few years ago now. That might be the newer one. What did your mechanic figure out?

There is special tooling and adjustment specs required for shall I say, "properly" servicing those steering pumps.

Sorry, maybe it was, I can't remember exactly what it looked like, has been a few years ago now. That might be the newer one. What did your mechanic figure out? He spent a full day with me going over everything. He asked me if my son and I had made sure the three blocks were put together correctly. I said yes. I took the steering assembly out again this morning and we compared the steering motor to the exploded diagram in manual and somehow, when my son and I put it together last week we inadvertently flipped the bottom piece end to end. We assembled it correctly and it works! Praise the Lord! I don’t want to blame my son but when two people are handling parts it’s harder to keep track. My son works for the local Arctic Cat dealership as a mechanic and he would like to be an ag tech so I let him take lead on this project. No excuse for me not paying attention. |
