3400 Power steering problem
Thanks Hobo. Those pics make it pretty clear. I guess someone had flipped the left side cylinder around on my tractor because the fittings on that side on mine are facing down, not up like yours, which would mean that the inner fitting should really be the outer, and vice versa. Thanks! -

3400 Power steering problem
Quick question: The manual says that the front line on the right side of the steering valve assembly goes to the inner connection on the right side cylinder. And the rear line goes to the outer connection on the cylinder. Same with the lines on the left side; front to inner, rear to outer. My... -

3400 Power steering problem
Never mind, I see that there are two more passageways that the check valve doesn't block, so now it makes sense to me why it would be on the return side. Any advice on why there would be enough pressure in the steering valve assembly to overpower a new and carefully installed upper seal would be... -

OK, I've been fighting with this for a while now. Multiple seals have been replaced. I ended up making a seal guide and was able to get the column down over the shaft without any damage to the seal, and yes it is lip side down. As soon as I started it up and turned the steering wheel a bit, out... -

3400 Power steering problem
I try to be really gentle when installing the housing over the steering shaft. It's really hard to see the seal once it's most of the way on, so when it goes over the last 'step' on the shaft I wonder if the lip is getting snagged and flipped upwards instead of facing down. Has anyone ever had... -

No it's a new shaft, so the surface that the seal rubs on is nice and smooth -

UPDATE - it only ran for a couple hours, and then fluid started spewing out from the top of the steering column. It had enough pressure that it was actually spraying out at me, from under the steering wheel. I figured I must have put the top seal in wrong, or damaged it a bit when installing it... -

3400 Power steering problem
Tightened with a wrench as tight as I could (which isn't super tight as I had one hand on the wrench pulling one way, and the other hand on the steering wheel pushing the other way), then backed it off 2/6 because that's where an old stake mark was. -

3400 Power steering problem
Got it working! You guys are awesome. I messed around with that thing on and off for weeks. Then after a couple days on this forum it's done. Sean in PA was right, I had put the control valve back together wrong. Actually I had put it back in upside down. I had wondered why the lines for the... -

What do you mean by "set the crush washer correctly"? I dropped the bearing and race set on top of the control valve, then dropped the spring washer on top, then tightened the steering shaft nut to snug, then backed off 1/6 turn, then staked it. When I take it apart I'll also look for a groove... -

Thanks for the reply, I guess I'll have to take it out and check it. Would putting the 2 weird pistons with the ball bearings in them in the wrong hole be a possibility? I used a picture I found online showing the 4 holes in the control valve and where the 3 normal piston pairs with their... -

New to the forums, and in a tough spot. My 1969 Ford 3400 was leaking psf from the column, and kept running low on fluid, so I would sometimes drive it with armstrong steering until I could get more fluid. Finally one day I was pulling really hard on the steering wheel and the 'steering adapter...
