[milton]

we have a jd 450b that was running great when all of sudden it stopped. oil poored out of the shifting lever on the transmission. don't know why. now the dozer will not go forward or backward. there was no vibration or unusal sound when it stopped. does anyone know where I would start on a trouble shoot for this or have a clue on what is wonge?

Milton,

I had a simiular experiance with my 450b. one day I was skidding logs and she just quit moving. After i looked all over the machine I saw some oil on the right side in front of the track,upon inspection I found that the line from the trans to the cooler had fell off the fitting. As I followed this line I found under the floor boards a short rubber hose hooked to the trans line. After I replaced the hose clamp and refilled the trans she was as good as new. The lines are under your right foot as you sit on the machine. I hope this helps, it is a sick feeling to just stop and not know why. Good luck. Let us know what you find,

We've all been there; a real PITA, but it is sooo satisfying when you figure out the problem and get it running again. Best of luck. Paul
