New issue with my JD 450c

This is my first dozer so I am all new to this type of equipment. I just bought the dozer last week and now I am finding out all the small problems it has. Able to fix most of them but I now have a steering problem. It occurs when the dozer in at a angle. On flat surface I do not seem to have the problem. Also it does not occur all the time it seems to be some what random. So here is the problem.....When I pull back on the right stick the dozer stops. The left track does not turn. With or with out a load. On flat ground it turns fine. I checked the fluid and the level is fine. However it is a little milky. So I think some water has gotten in there. I want to change the fluid (hoping that will fix the problem) Is the drain on the bottom of dozer? What type of fluid and how much? Also is there a left and right side to fill? When I checked the fluided under the seat there was just one dip stick in the middle so I assumed it feed both sides but I keep reading about two different compartments. My last question is is there any easy adjustments for my turning problem if the new fluid does not work? Also is there a cheaper PDF manual around for this machine hoping not to drop $200 just for a manual Thanks for any help you can give...

I have a 450C that is doing almost the same exact thing except the right side will quit pulling when I pull the left lever sometimes Usually when I am on a slope. But then it will work fine for awhile. I can drop the blade in the dirt and both tracks will just dig. I have checked the pressure it is running about 175psi but it does not react like the manual says it should it drops to low when shifting and takes to long to come back up. Shifting from forward to reverse it seems sluggish. I just changed trans fluid the screen was horribly dirty. Any ideas what else to check I suspect that something is stopped up since the pressures do not react like the manual says it should.

The HL-R powershift transmission has an adjustment procedure for proper pressure-swing and shifting. There's a an adjuster bolt under the floor that has a 5/16" or 3/8" jam nut on it. If you have a steering clutch that slips when getting 175 PSI, the clutches are likely the problem.

Ran the tests this morning.
1. Tried to stall it in 3rd but ground was to soft if I let just one side out it would just spin the track. Both left and right side. If I let both out at the same time that would stall the dozer.

2. When rolling it backward both sides brakes worked just fine.

3. When on hill and letting both levers out slowly at the same time I did find that narrow spot were it began to roll backwards.

Ran it hard for a half hour today and everything ran perfect. Both sides worded great had no issues. So not sure why some times it works great then other times it does not. Want to check the fluid for each side. Where do you check the fluid? Looked and could not find it. If low what type of fluid should I put in? If it is low would that make it slip or not engage? The dozer sat for over a year before I bought it perhaps it just needs to run a bit to unstick everything? I know I am reaching there....

Is uses John Deere Hyguard or equivalent. It's a combo trans/hydrauic oil. The HL-R transmission is what powers the steering clutchs. There's a gear pump inside the HL-R powershift trans that sends hydraulic power to the steering clutches. There's a dipstick on top of the HL-R trans. You need an operator's manual so you know how to check and maintain.

To try and better explain...When I pull the right stick back the right side stops as it should. But my left side stops as well. I am not touching the left stick at all at this point. It should be moving and thus turning the dozer. This happens when I am on a hill facing up or down. On flat ground it seems to operate fine even with a load. I will check the stall test today when I get home. Does this sound like my left side clutch is bad? If so how much doe sthis cost to get fixed. Rough estimate....No way I can do it myself. No time and to scared LOL.

Sounds like all you have - ever - is the right track driving. Left clutch is probably no good. As to cost? As to fixing? Wet clutch Deeres cost a small fortune to fix. One reason why I'd never own one. Many shops will refuse to warranty unless all steels and fiber linings are replaced along with seals. Often an oil manifold is need. 8 steels cost $450. 8 fiber disks cost $640. Seals and piston cost $200. A manifold if needed is $177. Total parts: $1500 not counting new oil. Labor? One full day to be safe. If shop rate is $80, that's $640. so such a repair just for one side can easily run over $2000. Make sure you check the pressure to the clutch and make sure it's geting the proper PSI. Have you looked under the seat to make sure the linkage is working right and the hydraulic spools are going in an out?

You need to explain the problem with more detail. When you say the left track "does not turn" . . . is that with the left lever fully engaged (take your hand off of it)? The left side has nothing to do with the right side. It sounds to be that your left track hardly has any power - ever. You don't notice it until you take the power off the right track. Also . . what does "not turn" mean to you? You can turn slowly by declutching, or turn fast by declutching AND braking. Need more description. Each side has a clutch and a brake. If the clutches are slipping - the wet disks are probably ruined but it won't hurt to check the pressure to them. If the brakes aren't working - they're either worn out or out of adjustment. The "C" series was the first to have self-adjusting brakes. They worked terrible and were often disabled. If you want to test . . do this. Put the machine in 3rd gear. Hold your foot on the brake hard or put the blade against a tree (so the crawler cannot move). Have the macine in 3rd gear, low range with both steering levers held all the way back. Let the left one out slowly. You should be able to stall the engine. If not, the left is slipping. Then do the same with the right. To test the brakes do this. Park on a steep hill facing up. Must be steep enough to the crawler wants to roll backwards in neutral. Let it roll as you apply each brake, one at a time. See if each track stops. You can also do the same test rolling forwards if you want. To test clutch/brake adjustment . . park on a steep hill again , facing up. 2nd gear, L. Hold both levers all the way back with your foot on the brake. Let both levers out (towards the front) slowly. There should be a narrow spot where the crawler starts to roll and then a little further, it goes forward. That narrow spot - with no brakes and no clutch must be there. If not the clutch power fights against the brakes whenever you use the levers.

First thing you want to get is an operators manual.
