I have a 450 c john deer and need to break the track so I can replace the seal in the track adjuster. The only difference in the pins is one has a hole in the middle of it, I took that to be the king pin. But the problem is I can't get the pin out. Have tried heating and driving but it does not move...

I guess I confused everyone. So I'll try again. If I put it up a big tree both tracks spin. If I pull the right lever the right track stops, when I release the lever it starts spinning again. Now when I pull the left lever if I gently pull the left stops and when I release the lever track starts spi...

Yes it's a C. If push something unmovable both tracks spin down. Until I pull the left steering lever then the left stops turning until I hit the right lever, brakes or clutch then it starts pulling. Does not matter how hard I pull the right lever all it does is turn. The left will turn as long as I...

Finally got back to working on the ole 450 c. Having trouble with the left steering. In 1st low if you pull hard on the left steering it stops the crawler, to get it to turn I have to pull real slow on it and it will turn, but if ever pull the hard it stops and will not start moving again until I pu...

Happy New Years everyone. Still having problems with the steering on the 450 c. Ordered the service manual, but it does not show pictures in the manual that looks like my setup. The books shows to adjust the steering clutches to take the plate off the to of the housing and adjust them inside, also t...

Its in the final drives, when I take the fill plug, just above the tracks, there is pressure. Been raining here so have not looked for the vennt on the filler tube.



Thanks

My 450 c builds up pressure in the final drives. You can run it a bit and take the fill plug out and there is built up pressure.

Should there not be a vent tube that is stopped up and I just can't find it?

Thanks

Finally got the service manual on the 450. It shows to adjust the left steering I need to screw the adjusting knob in till the self adjuster will catch and have 6" of pull on the lever. But the problem is it does not say how to get to the adjuster, the best way I can see is to take the top of the ho...

Hi Have a 450c that I am trying to get going. It has sit for 3 or 4 years, Changed all the fluid in the transmission and the drives. The crawler steers good for an hour or so then when I pull on the left track it stops and the right will stop also, I can then pull back on both levers and it will go ...

The tag on the side says 450 C J not sure what the J stands for. Serial # 228579 T.

Both sides had pressure in them, should there have been. and both were over full. When I took the plug out oil squirted out.

Thanks again

Hi everyone, new to this site and new to working on a jd 450 c. Just acquired a older 450 c that has been sitting for a while. Started it up and drove it a bit just to check it for running. Changing the oil in all the drive trains and transmission as they were milky. Changed the xmission oil and fil...
