I'm in the process of converting my 317 over to power steering.

I also took a ton of pic's of the rebuild of the hydraulic steering unit.

There are WAY too many pic's to re-size and post here.
So here is a link to where I have my orig. post.

Here's a teaser pic though.

Thanks,
It's a work in progress.
Keep checking back for updates.

I didn't mention this in the 1st post but the link provided is VERY Picture intensive.
So those with slower connections should be warned.

Bob,

That is a great write up, thanks alot for sharing. The documentaion with the pictures is fabulous. I have not rebuilt a steering column but feel better about doing it now after reading that.

Thanks that will be very helpful if or when I get to take one apart. Nice to know about the little things that can jump out and you spend hours looking for them. They always seem to find the strangest places to end up.

That's an incredible documentation..great job ! Buut, me being a machinist, you listed that one dimension from reading your calipers /verniers as.70, just over 11/16ths (11/16ths which is .687) and your reading shows .370 which is under 3/8's of an inch (.375)
Just so nobody gets any thoughts that they need to open a hole up going by that 11/16 dimension is all I'm trying to stop. I'm not trying to take anything over...once again, great documentation !

Great job, Bob -- especially documenting the control valve overhaul. I'm looking forward to seeing how you mounted it in the tractor.

Mike,thanks for the correction.
Looks like I was just reading the dial and forgetting about the scale
I'll see about getting that corrected in the post.

I appreciate your expertise... as reading calipers is not mine.

There's a small update now.
.http://www.mytractorforum.com/showthread.php?t=208848

I'm asking for a link to a hydraulic schematic for a 420/430.
The J/D parts site has good illustrations but nothing that actually shows the routing.

I need to figure out the Hydraulic line routing.

Also whether the pressure line from the pump goes to the spool 1st then the steering or the other way around.

Bob, I'm in the middle of a 140 powersteering conversion right now, and the general consensus around here is that the pressure line should go from the pump to the power steering valve, and then to the spool valves. The reasoning is that the power steering has priority and you don't lose steering pressure while turning and raising an implement at the same time. That is why Deere switched from a 4 port steering valve in the earlier tractors to the 5 port.
Excellent fabrication work! I have had to do quite a bit to mine, but not as much as you. Great documentation too!

If the steering valve has a power beyond port, it should absolutely be the first thing in line after the pump.

Oh man oh man. I remember "toasty" from years back. Has come along way from its days as a fixeruper! I will be following this VERY close. I have a 317 and been scratching my head how to retro it without going the 400 series route..... Keep it going. Archive this link for sure!

"If the steering valve has a power beyond port, it should absolutely be the first thing in line after the pump."

It has an "IN","OUT","AUX","LEFT" and "RIGHT" ports.

bob,

Here is the hydraulic schematic from the TM1950 which show the sequence of the plumbing from pump to 5-port steering valve to attachments and back to reservoir. I will e-mail you a much higher excerpt and the legend of what each component number is described to be. I did not have the 420 specific schematic at the proper resolution to post here, but the differences are slight -- just the third spool of hydraulics for attachments...



By the way, very complete rebuild thread on the other site with great pictures!!

Chuck

I would imagine that "out" is your tank port and that "aux" is your power beyond.

I hope so because that's the way I routed the hard lines I made.

#1 is the feed to the power steering unit. #2 is the return to the pump. #3 out from spool. #4 out from steering unit. #5 is of course the "T" fitting. #6 is from the "AUX" on the steering valve to the "IN" on the spool.

Bob, great job on your build, I may have to make some tubing in the future and was wondering what size, brand, material, and thickness of tubing you used, specifically for the tubing that connects the hydro pump to the steering. Thanks for your help, and again great build!

It's just regular steel brake line tubing.
3/8".
I got all my JIC fittings from discount hydraulics.
.http://www.discounthydraulichose.com/


I didn't measure it but brake line must be .028" to meet DOT requirements.
The burst PSI of steel brake line's can easily withstand 3000psi so this application it should be just fine.

Here is a 1.5min. video I made of the road test.
It works great!
