I think you can buy them off of www.jdparts.com . I have not bought anything from there, but they have prices listed after you create a username and password. My local John Deere dealer uses the same website, you can have parts delivered to your house or to your local dealer. Of couse this is a John...

Thanks for the input everyone. The bypass valve was the issue, also needed minor adjustments to steering clutches. Now it is putting power to the ground, but the motor needs some tuning up. Luckily my buddy is a deisel mechanic. Thanks again. JamesTrent

Randy, There is another ball inside the port below the pilot valve, acts as a check valve to hold pressure against bypass valve to keep it open. As for why it moves I guess it gets enough flow through the needle valve possibly a little fluid bleeding around the bypass valve. Definitely not working a...

I have found a problem (if not the problem) with my H-L-R. Seems someone has been in there before and put the bypass valve in wrong(spring on wrong side) and lost the ball out of the pilot valve. Filter screen also gone. Parts on order. When I get it back right, maybe the added volume will keep the ...

Randy, Your right about the pumps. So you think the main engine clutch may not have enough free travel? I have the service manual and it gives about four pages of information on how to adjust clutches and valves in transmission. I am going to start with this and if this doesn't work I'll get back wi...

I understand that, but they are both powered by the same clutch aren't they? Between the motor and transmission? The power goes to nothing as if the clutch in my transmission is becoming disengaged. It doesn't slip, it stops, and it doesn't regain power until it is shifted to reverse and back to for...

That doesn't seem to be the issue because once the machine quits moving I can still raise and lower the blade and the dozer still will not move until you reverse direction. Relief valve maybe?

We just purchased a 2010C and have a problem with the H-L-R transmission. All eight speeds seem to work well until the dozer is put under enough strain (where most motors would start to bog down)then it is like you put it in neutral. We have cleaned the filter element, changed the paper filter and f...
