Re: 450B steering clutch opinions

Unfortunately I have heard of several people going with the poor quality fiber discs and had early and total failure. Consider contacting Lavoy, owner of this site. He may have these discs available. He only sells/deals in high quality items. I don’t have knowledge of the bi-metallic discs you have ...

Re: Any you guys ever hear of this ?

The Deere 450 crawlers only use shims in the front idler forks for aligning the track in the center of the idler wheel. The grease is left in the adjuster. This adjuster is attached at the rear to a large spring. The idler floats at the front and if the front is impacted the energy is transferred to...

Re: Oh boy, need a lot of track help

If you have not found an idler from the above sources, consider this contact. C&C equipment out of IN uses this company quite a bit and recommends them highly.

Re: Oh boy, need a lot of track help

“I found that the idler has some considerable slop when prying on it. I don’t know if this amount of slop is normal with the tension removed from the idler. But, something is telling me it’s normal.” This is not normal. Given the fact that the rest of the undercarriage is I great nick, I would say t...

Re: Oh boy, need a lot of track help

I’m going to assume there is significant wear on your undercarriage, given that it has spontaneously derailed. If it is good to great shape there will be no short cut, but to drive the master pin out or uncouple the master link (if you have a new “wet chain”). You can release the track adjuster, and...

I believe the relief valve is only active while you are using a function and the lines may see a higher pressure when you are not using that function. Think running into an obstacle.

Correct, there is a difference in nominal operating pressure and burst pressure.

Re: What PSI are 450 hydraulic hoses for loader ?

Should be fine. Pressure relief is usually around 2,250.

Re: What PSI are 450 hydraulic hoses for loader ?

I use two wire hydraulic hose. I think max operating pressure of 6,000. I am pretty sure the two wire hose is what was used by Deere for the loader application.

Re: John Deere 450b

Turbo is under the hood about mid-engine. Find the heavy flexible rubber hose supplying pressurized oil to the turbo. Follow that hose back, you should then find the port block, unless someone has heavily modified.

Re: John Deere 450b

Good morning, If turbocharged, the oil supply line to the turbo should have a steel block with multiple ports on the right side of the engine. The should be an electric oil sending unit screwed into the port pointing up. And a wire heading to the oil gauge in the dash. Yes, there is an oil return fi...
