861 valve adjustment?

DD in WA · Jul 29, 2018

I bought an 861 four or five years ago to mainly use for baling. It does a fine job and having a live PTO sure makes life a lot easier. My question is about the valves since they seem somewhat noisy. I
assume I'll need to remove the hood and gas tank to even check them let alone adjust them. Is this correct, if I can do it without removing them that would be great. More general and perhaps more important
question is what will happen if they are 'loose' and I don't properly adjust them? Will they just remain noisy or will some serious damage occur? It's also entirely possible they make the amount of noise
they are supposed to and I'm just to dense to realize it....

Appreciate your thoughts.

I have a diesel engine that my kin tried to adjust the valves because he thought that was the problem. I found out later that it is in the valve train. I still dont know what it is, its either worn out gears or the plate that holds the cam in position is broke. The way you can tell if its valve train and not adjustment is to put a heavy load on the 3-point. When you are lifting it, the noise will stop, set it back down and the noise resumes. You can set them by just removing the valve cover. I would just set them cold and be happy they arent sloppy. I think you have to loosen the tank to head mounts and put a board under the tank to hold it up a tad. If yours is a gasser you could take the lifter side cover off and just check by hand how sloppy they are. We have a tractor that had a remote on it that wouldnt kick out in one position automatically when round baling. It gave the crank and cam and pump gears a fit, we replaced both gears in the front. I would put a pressure light on any valve like that now to light up when under load.
