D4 dozer hydraulics.

I can,t quite picture what the problem is there but could you adapt hoses along with the pipes to work or would that be a problem too?

hello d2 davie,
I have the lines for the double valve winch application but they are currently off the tractor.
As far as installation the 44 lever stand moved to the outside edge of the fender, then the winch control, then the lines have 90 degree offsets to the inside around the winch control. The lines from the transfer valve stay stacked all the way. The through lines are stacked until you get past the winch lever, just ahead of the seat where they offset to stack above the other two lines (now four lines stacked) as they go around the tank seat. My installation got somewhat buggered up when they split the winch control bracket in order to route the lines around the ROPS installation but the lines were only slightly tweaked. If no one comes up with an original installation picture in a couple of days I will post some pictures of the lines if you like.

Maybe I jumped the gun.....I'm assuming you have the tank seat model for which the above description fits.

Thanks for replying guys, old magnet your spot on it does have a tank seat I was wondering about moving the control lever bracket, a picture of the cat setup would be great thanks.

I have a 7U with a double unit. One for the #4 Toolbar and one out the back for implements. When the wife gets home from her Grandmother's I'll try and get some pictures, if it ain't to dark in the shed. She is the camera pro and then I'll have to see if I can figure out the pictur posting thing.

Hi toolbox,
It's the winch installation that makes the normal setup different. The extra bends and routing changes to miss the winch control bracket and the winch brake lever makes it different than the normal four line set up. Does yours have the D4N Hyster winch?

Sorry it took so long to get back. Things went to sh#! at work I have been busy. OM, no mine does not have a winch, I've got a 540 RPM pto and a homemade cab. I guess I did not read the post close enough. I still need to figure out the picture posting deal though.

Thanks anyway toolbox, I will try to post a pic.

Hi d2 davie,
I did some more investigating of my hydraulic lines and concluded mine is probably not the best reference. As I mentioned my installation has been altered for the ROPS. I took some pictures anyway and researched the lines (still had the part number tags on them) and find them to be the standard units used for a four pipe installation. The set that go to the transfer valve is pt # 8F8443, the straight through set is pt # 8F8440. For my installation they had to get the four pipes stacked to get past the ROPS support but in checking dimensions I see no reason why the stacked pairs would not fit and still miss the winch brake lever.
On this particular installation the control lever bracket was moved so that is 1-1/2 in. from the edge of the fender.
Hope this helps.

Thanks old magnet for the part numbers and pics. I will have to move the handbrake lever for the winch and the control lever to make the make the pipe work look as origional as possible will post some pics when finnished, thanks again. (d2 davie)
