This may have been covered elsewhere, but I'll ask again. Does anyone know how to hook into the hydraulics on a D6R, to provide hydraulic power for a rear mounted implement. The implement has its own control valve stack, so all i need is hydraulic supply, return, and sense. Ken
watglen, is this a tile plow if so yes it is covered elsewhere, if i remember the tile plow for some unusual reason took higher than main relief pressure which if i remember they were saying was 3500psi. otherwise it would hook up just like a ripper valve. get back with more specifics and i will try to cut and paste system operation from the service manual............theironoracle
Yes it is a tile plow. If someone could find the relevant thread that would be great. I know the 6R has a relief pressure of 2800 psi, which is a bit low by current standards. I would hope that CAT includes in their valve design the necessary ports to make this easy, but maybe not. That's what I need to know. Ken
watglen, yes the ports must be there, they would be the same ones the rippers are plumbed into, worst case you would need to install the ripper control valve in the stack and then plumb it to the rear. i haven't found the picture in the service manual yet. does this have diff steer? you could also PM leeonline he is the best with this stuff...............theironoracle
Yep, diffsteer series 3 2006 model year. WRG series.
I got it done today. Not too bad of a job. Found a good hydraulics shop to help me. Figured the fittings etc. CAT dealer gave me the connection points. The rest was straight forward. Hardest part was removing a broken bolt in the return line flange on the side of the hyd tank. Nice looking too, pretty proud of it. Still have to do a bit of leak testing, then put all the panels back on.
If your going to be pulling a tile plow why do you have the hoses coming out the front of the machine not the rear??? Maybe you have them out the rear also ,just wondering your thoughts.Looks good!
A little more sunshine, and I'll take some video of it in action. There is supply, return, and sense on the rear of the tractor. Incorporated in the stinger is 3500lbs of steel blocks. Should come up to about 6000lbs total extra wt on the blade, with a maxi loaded. Hopefully that's enough to keep the nose down. And the stringer is set up to attach to a 3pt hitch on a tractor if need be. Waiting on the plow to arrive. :drinkup
Looks good. What do you do if you run out of tile on the front before you reach the end of the run?? Bring over the excavator and dig in a joiner? Or do you load up a fresh spool for each run? Andrew
You use a loader to deliver a fresh roll in your path, then tilt the stringer, drive into it, tilt it up, connect and carry on.
The stinger is pretty sweet the way it's set up now. Two pins, lower to the ground and back away from it. It is on or off in under a minute. Also, I can haul the whole rig plow, dozer, and stringer, on the lowboy without need for breaking anything down. Should be pretty sweet.
Ahh, I understand! Not much tiling here, so I'm not too familiar with the process. Just need some pics of the complete rig with the plow on! Andrew
looking good watglen
What kind of plow did u put on the back of of your d6?
Hi Pipe Installer, Its a bit of a home built, just not built by me. Bit of a prototype too, in that it needed major redesign to work properly. It had a really strong tendency to lift the ass end when you started pulling. Have been working with it the last few weeks, and it is working really well now. Besides that, the hydraulic package is a top of the line proportional valve setup, 6 spools, with a wireless remote in the cab. Trimble GPS does the work, with a laser control box included for working where sats are not available. Pretty happy with it at this point. I can hook you up with some of the people involved if you like
