Post by b13150 » Sat Dec 10, 2011 9:07 pm

I am getting different answers if you have to split tracks on 450b to replace steering clutches. Some say you don't some say you do. Can anyone be of help on this.

450b steering clutch

Post by b13150 » Tue Jan 24, 2012 11:12 pm

I talked to a john deere mechanic that says you don't have to pull finals out on 450 just 350 . More on dieselbomber web site say the same. Can anyone clear this up, is splitting the tracks really necessary.

YES!! You have to split the tracks! NO! You don't have to pull the final drives on a 450! YES! You do pull the finals on a 350! Go look up crawler123s thread. It doesn't get any plainer than that! From start to finish!

You do have to split the tracks and remove the sprocket. This is necessary as you need to remove the bearing cup and shaft that the steering clutch rides on. This is not a caterpillar tractor but a John Deere.

Retraction On Track Splitting for Steering Clutch Removal

Post by JWB Contracting » Mon Feb 06, 2012 9:09 pm

Hey guys, I need to retract my statement that you need to split the tracks and remove the sprocket to pull the steering clutch on a 450C in all cases to - this does not apply if you have the 33" wide track kit installed.

We just changed the o-rings in both steering clutchs on our wide pad 450C dozer mahcine this weekend. One was bad so we changed both.

One other tip, we run a piece of roller chain around the steering cluch and then bolt it together with a lifting eye in between. Makes it very easy to lift the steeing clutch out with a small shop crane.

I must have turned the brake bands end for end as I had to adjust the brakes manually, had to tighten one and loosen the other. We like to make sure everthing is operational before installing the hydraulic tank, battery box and fuel tank.

I bought an owners manual on ebay froim ID justauctions It was as advertised and worth the @$15

I also bought the service manual online, but in a pdf format. I wanted it for the electrical layouts which it has. I don't know if it has what you would need to replace the steering clutches, which is a good chance what your steering problem is. I just went through that with mine, as I purchased it not steering as well. I paid to have it done though.

Hopefully you understand that the "no steering" issue and the hydraulic leak issue are seperate. I'm sure you do, but some people assume the 450Bs are "wet" steering clutches and pour Hy-Gard down the steering clutch housings which promptly ruin them.

There are a number of ways to get the operator, parts, and tech (service) manuals for the 450Bs, but the easiest is to order online from Deere. You can get in a number of formats- PDF, CD/DVD, hardcopy. The parts manual can also be viewed online for free. if you scroll down on page 1 of this thread, I include the hyperlinks for these:

450B no steering

Post by Jack-the-Ripper » Tue Nov 20, 2012 12:33 am

Inside the clutch housing is a vertical rod with a bushing on each end. An arm on top is activated by the steering lever through linkage. An arm in the middle engages the throwout bearing. The "Bs" get moisture in their housings which rusts up the bushings on this vertical rod, which gets stuck in the disengaged position because it is only a spring that returns it (which may also be broken). If this is the case, you remove the clutch pack, and then may have to use every trick you know to loosen this vertical rod enough to remove it. I cleaned the rods and bushings, applied grease liberally, and reinstalled the rods. Before installation I drilled the bushing mounts and inserted and epoxied small copper tubing that I extended out through the back of the housing casting that I drilled through (sealing with J-B Weld), installing zirks on the external tubing ends. I ground a circumferential groove in the rod's ends so that when I occasionally grease these bushings the groove hopefully will allow the grease to flow all the way around the rod.

If you pull the housing cover and find that the upper "arm" on the vertical rodis all banged up, that is a good indication that the rod has been sticking.
