YM226D Power Steering Rebuild

[Neat 1500]

I believe it is no good to you the way it is at the moment so it needs to be tried. If it is damaged and can not be used then you will have to set it up for manual steering. I don't see any other way to go about this being a rare option.

Or fab something up, off a JD or Kubota or something. It can be done. Something for a similar size tractor and something that can take the volume of the pump.

No doubt it can be BUT it depends on how much you really want PS?

Just speaking for myself - power steering is such an improvement for my use that I would pay what it takes to repair or replace mine if I ever have to.

Yesterday is an example, I was towing the watering trailer all over the orchard watering new trees at random spots between mature trees. Its near harvest so there are props holding up many limbs, this means lots of extreme turns to get to each tiny new tree that is next to, or between, trees with props. On slopes steep enough that I have to be cautious that the heavy trailer won't jackknife me sideways down where I don't want to go. It feels like I have the steering at full lock left or right 1/3 of the time. This is disced, soft ground so the resistance to steering is considerable. It was exhausting on the prior Yanmar without PS, this present PS makes a huge improvement in how much I ache after a day of watering. Think of these two photos combined: (1) (2).

Not everybody zig-zags around like my application but for me PS is a night/day improvement.

Oh yeah for sure. If it wasn't so expensive and me around the other side of the world I'd fit it to my 1500 in a flash! When I have a busy tractor day my arm's are tired from steering it.

I'm here in the US and that new kit that Hoye developed is cool but I just can't see spending that kind of money on it.

Typical application where power steering is helpful: zig-zag down a slope to water new trees. A few hours of this on the prior tractor was exhausting, tugging on the wheel making tight turns in soft ground.

All that bare ground amazes me! To get that lititle Gras around here I would have to spray herbicide 2x a year!

 

[California]

Normal is no rain Easter to Thanksgiving, no herbicide needed. Discing late spring to turn the grass under is all that is needed.

It's an old California joke you can only sell rural land to newcomers in the winter and spring when everything is green, because the dry summers don't look right to an Easterner.


Sorry Smoody, I didn't mean to pull your thread off-topic. Any news?

It will come full circle again!! Hahaha

How the heck do the apple trees produce or grapes of there is so little rain?

 

[California]

Modern grapes are drip-irrigated at each vine. A few historic plantings remain that are dry-farmed same as the Romans did. They don't produce much but are prized for flavor.

I'm only 10 miles inland from the Pacific Ocean so the trees absorb moisture through their leaves, from the fog that blows in most nights in the summertime. Its normal for the sky to finally clear around 11 am.

This coastal belt is one of the few regions that dry-farms apples. Farther north in Washington State, irrigation for apple orchards is common.

Digging up this oldie to see if Smoody was still around with an outcome. I have the same cylinder on a 330D and its been doing this 'squirting' thing for years, but I think its getting worse.

Farther up in this thread is a link to another thread
http://www.tractorbynet.com/forums/yanmar/218151-anyone-have-pics-power-assisted.html
that discusses the same thing. There are pages from the PS manual - scattered across several posts - in that thread that should be sufficient to visualize the repair.

In summary, O-rings, #11 in the diagram (two of them) are what leak. The one at the tip of assembly #15 is what lets fluid escape and go out the vent hole. Don't take apart assembly #15!!! It is factory-calibrated to not pull the steering left or right. It can be removed intact.

The difficulty I have encountered is the big nut that holds assembly #15 in place can't be turned by any reasonable force I can apply. I can't imagine how to clamp the delicate aluminum body casting in a way that would take the force needed to loosen that nut.

Also as I recall the manual and I think a prior poster said the large steering piston assembly has to be removed from the aluminum casting before removing Assembly #15. It looks to be in the way of turning the assembly #15 nut.

Gjamtrac in that other thread sounds like he has repaired these. He might have some advice. Looking at his prior posts I found this
http://www.tractorbynet.com/forums/...teering-hydraulic.html?highlight=#post3532774
where he says you remove the flat cover off the side of the PS casting and remove its internal parts, then unscrew the big nut to take out assembly #15.
Perhaps it isn't necessary to take the PS off the tractor to repair it.

Gjamtrac hello, are you out there? Help! :yell:

California ? When you're not doing grapes and "homework" do you ever sit down ?

At the moment I'm stuck indoors with plenty of time to fool around online.

Yesterday I posted to another Californian's thread titled It's been HOT:

My ranch (orchard) is an hour north of San Francisco. The NWS weather station nearby recorded peaks of 118.4 and 115.6 degrees over the last two days.

I shut down and retreated to my home over in the Central Valley where I have competent A/C.

The photo below is the last project I completed before saying the heck with it and bailing out. The apple orchard is operated commercially by a neighbor along with his own larger operation. We have some family fruit trees interspersed. I stripped a couple of family trees including this little pear tree, to take home.

The usual breeze coming in from the ocean 10 miles west of the ranch finally resumed so the forecast high for tomorrow 79. I'm headed back over there in the morning.

Sorry California, Apple's not grapes. It is Apple's right?:licking: Bless you and your hot weather. Been mid 60's /mid 70's back here in Pa.:thumbsup:

... Apple's not grapes. ... Been mid 60's /mid 70's back here in Pa.

Yeah, I'm one of the last holdouts. Nearly all the neighbors have leased their land to ag contractors who converted to grapes and fenced their parcels. In some cases fencing the landowner out of the land he used to roam freely. Now the owners have a view off their porches that looks like endless vistas of factory farming. My mature apple orchard continues to feel like living in a forest. I like this better.

But I did have to finally fence last year. With the deer fenced out of everywhere else this had become the neighborhood zoo. I counted a herd of 18 at one point and generally 14 deer living here. Photos from the past: (1) (2).

In my prior post, see the caged 2 year old tree across the lane from the pear tree? Even cages didn't slow down the damage that deer did to new trees. They learned to climb on the cages and crush them to eat the tasty new buds. Finally, reluctantly, I gave up and agreed to fence the place so our replacement trees could survive.


Wow, 70's there? You are fortunate.

 

[clemsonfor]

If you start shooting them you won't have 18 at a time, there pretty smart!

Even here we have the last few days have hit 90 but night is low 60s or upper 50s. And have had highs in the low 80s some days

Thanks California. I read through the manual pages posted but wanted to hear from someone who was brave enough to have done it/or have it done. Tofay I took some zip ties and a piece of inner tube to mitigate things.

That works for me.

I too hope someone can show us how to take it apart without distorting that irreplaceable aluminum casting.

I put this on after I got the tractor home and cleaned up. It's not elegant but it ended the upward spurt that was getting all over everything.



And kinda related: The power steering control valve is larger than the tie rod it replaced. I've seen dents in the oil filter where it was touched by the P/S in at full steering lock, and likely with extreme tilt of the front axle also.

So the little #1334 filter, 3 1/8 inches tall is the largest one suitable. There's an even shorter filter made for Subaru that would work too.
