Re: HLR is driving me crazy

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...

Re: HLR is driving me crazy

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...

Re: Top Roller Replacement or Just Replace Seal?

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...

Re: JD 350 Straight Diesel - What Are Y'all Seeing for Compression PSI?

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!!

Re: Removing control valve without removing engine or reverser housing

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...

Re: Welding Rebar on for grousers

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...

Re: Starter Wiring

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 .

Re: 350 Reverser Breather/Vent Hose?

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...

Re: 350C Power Issues

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...

Okay so third time is the charm!!! You will have to look over me because I'm old dude... You can't fix old!! Anyway after looking at the pictures yet again at JD parts you are correct. the screen is on the front of the case. Again... sorry to have led you wrong on that. So I think I'm done. Time to ...

Re: 455G shifting issue

On the screen position??? I went and looked at the picture on JD Parts and I think that screen is actually positioned in the rear. I may be wrong which here lately I have screwed the pooch on a couple of questions. But again... a good operators manual will give you that information. I really can't a...

Re: 455G shifting issue

Just the little bit that I know... Those "G" models do not like dirty filters. If your transmission filter hasn't been changed then that would be a great place to start. I don't remember exactly where the screen that Jim mentioned is located but I think they are serviced from the rear of the machine...

Re: how important is power steering on the 350?

It's not a necessity but does make the steering easier. However the system can be fiddly and problematic. The other issue would be finding all the parts. Probably salvage would be your best bet. If it was mine I wouldn't make the change. But that's just my opinion. If you enjoy dinking around with s...

Re: 350C Power Issues

No... there are two sealing rings on the manifold itself. Look in the parts breakdown for the reverser assembly and you will see the manifold and then a steel ring on either side. One for forward and the other is reverse. Now that being said... the ring you referred to can cause issues with slippage...

Re: 350C Power Issues

I have had these do what you're describing and in most of the cases it was a leaking seal in one or the other of the clutch packs. I have also seen the steel sealing rings on the manifold leak and cause your issue. And yes, they will sometimes go ahead and spin the tracks in first gear but not in an...
