Thanks for the reply. I'll give it a try.

So what needs to be replaced? Just the steer bands?

Thanks for the reply. I was thinking of a cleaner/degreaser as am alternative to a complete tear-down. In using the machine this morning for approx. 2 hours, one side does steer but the other is quite weak. Since both chambers were filled with the oil, and drained and flushed, I thought that maybe t...

Hello everyone On my machine, R/O tractor oil was inadvertently put into the clutch housings. Believing the tractor had wet clutches, instead of dry clutches. Although one side (left) came back to life after both housings were flushed out with Kerozene, the other has very little steering capability....

There are a number of hydraulic schematics in the hydraulic section of the 450B manual, including at least one for the 6 way blade. There is an on line copy you can down load at https://archive.org/details/John_Deere_Company . The manual is the center in the top row. I down loaded it in a pdf forma...

I'm guessing you will need the manual for the dozer itself.

I do have a manual for the machine, but it does not discuss the 6 way blade but rather the loader only

I am in the process of installing a 6 way blade on my JD450 (straight). I'm looking for a piping diagram to help me get everything in place. Although I have a very comprehensive maintenance manual for the machine, it only covers machines with loaders, but not the the 6 way. I do have the 6 way valve...

I did indeed try what you originally suggested, but the flanges of the roller won't drop out of the main heavy C channel, therefor the roller has to drop out straight down, and any slight angle will cause it to bind and not budge. It might of been just easier to actually remove the entire carriage, ...

On another issue, I removed the outside lower carriage guard today by removing the 12 bolts, from the main rail carriage heavy channel iron. Then I unbolted the 10 bolts securing the roller flanges to the main frame as well as the ones holding the roller flange to the opposite inside frame. Long sto...

The plate was originally, as your sitting in the machine, would be facing the inside of your right leg, towards the floor pan. You can see where it was located, by the paint that is not discolored where it would if been mounted.

Unfortunately, the serial # plate for my machine is missing. Even though I can ID the location where it should be, I have no idea as to what year it was manufactured..

I don't have the service manual handy. Not sure where to get my hands on one either. eBay have many service manuals available for the 450, But I'm not sure which one I should buy for my machine. I own a straight 450, so mid-70's?? I will take the service manual number you mentioned and see if I can ...

That's definitely doable. I have the track & chain removed, and looking at replacing all of the 5 rollers on the left hand side. That's a lot of less work then dismantling the entire carriage!!! Thanks for the heads up. Much appreciated. P.S.: I got the assemble drawing from the JD parts site. Wish ...
