Your crooked retainer could have been any number of reasons. Given my experience with these spring isolators, I would bet that at some point a spring broke which is when your pin got hammered loose and your retainer got tweaked. Then whoever replaced the spring put it in backwards and just stuck the...

You are correct that the one spring is wrong. That being said I have taken machines apart that had the springs in the wrong position and had ran like that for years. Once the machine has been started and everything is rotating I don't think it really matters. But technically and according to Deere t...

If your hydraulics are settling then it is either the spool in the control valve or the cylinders are leaking past the pistons. When you say it is several minutes before it settles, I would bet on the seals and packing inside the cylinders are old and worn from age. The spool in the valve should be ...

This sounds more like you have a spool leaking past more than any of your check valves. Have you pulled the valve apart and inspected the spools and bore of the valve itself? I've only seen this a couple of times and both times the control valve was worn out and leaking past the spools when you try ...

Well it's hard to say about permanent damage. Your reverser needs a bare minimum of two gallons of fluid to operate properly. I would have to go look up what the capacity is but I know it needs at least a couple of gallons to operate. You may also have filter issues. If your filter is stopped up the...

You need to check the fluid level in your reverser first. Not likely for both steering clutches to just quit at the same time.

I saw the ball you're referring to in the parts diagram. Unfortunately I no longer have my books on these 450's and it has been way too long since I was last inside one of them. But... I think that ball goes in from the top as it is shown and then there should be a regulating valve go in over the to...

So where exactly did you discover this ball? The only ball I can think of that might have an influence on your pressures is in the Clutch Oil Manifold. I don't know how that could have gotten out of place but it is the only thing that I can think of that might have an influence on your pressure. Usu...

Well... yes you can take the roller off and replace the seal without pulling the bracket off. But... your roller is junk dude! When a roller is worn down to the outside diameter of the cap then it is due for replacement. You can just replace the seal but you're still going to have a worn out upper r...

Your numbers are great dude! A brand new engine might be a bit higher PSI than what you have but it wouldn't be much. And even then once it breaks in they would settle to about what you have. Looks good to me!!

You got lucky dude!!! :D I was never able to pull one without first pulling the reverser. The reason is that if the machine has never been apart then the reverser valve body will be attached by at least two studs with nuts and then the rest will be bolts. Yes you can get the bolts out and the nuts w...

I have seen guys use rebar for grousers but they tend to be brittle and will break off. You can still buy grouser bar that is made for re-toeing dozer pads. It usually doesn't cost that much more and you have better toes when you're done. I quit re-toeing pads because you can buy aftermarket pads fo...

Just in case you want to know for sure... You are correct in thinking that wire was for the gas engines. If you were to look behind the dash panel there would also be a resistor missing and the other end of that wire you found. Later machines didn't have the wire in the loom .

Okay so at some point your machine had power assist on the steering or that reverser came out of a machine that had it. That line you have pictured is the return line from the steering system back to the reverser. Later "B" model machines did away with the steering pump that was mounted to the front...

Yes... I think you have a seal or a combination of seals that are leaking past. You could also have disc and plate wear that could causing this. But your pressures seem out of where they should be. Your clutch will dump the pressure when depressed. That's basically all it does. It is basically an on...
