Curious if anyone knows about compatibility between my 1940s d6 5r that's converted to a hydraulic front blade with the 'suit case' front mount kit and a bee ge rear hydraulic kit that I found on marketplace . I would love to have aux hydraulics added to my dozer. I found this unit for scrap cheap but I am not sure if if it's a good starting point on a project.

I would assume I need to fab a coupler. Not sure about an rpm issue. 

My dozer has a plate over the back currently.

Someone might correct me, but here goes: The D6's run opposite of a D2 or D4 so you might have to reverse the pressure/supply side of the pump by separation; just a 180 degree flip is all. That one has 2 spools, the photo is not the best, but hopefully the valves are not "rotary" type. Slide type valves are the later, preferred style.
Get yourself the on/off in/out box if you want to be able to have it disengaged when not needed. It will give you an additional 4" I believe from the back of the tractor.
The flange for the base and shaft should be available from Associated Tractor Co. Stockton, CA as they carry parts and own the rights to BeGe. FP Smith in Cordelia, CA might have some stuff too.
If you are lucky enough, the one you get might still be usable. It always baffles some of us why a BeGe unit is off a machine and available for sale. I have had anywhere from basically new, never used, to ones that looked pristine and major leaks or internals missing, etc.
It never hurts to have extra hydraulics.
If you are close by, I might have some extra parts available. (Yuba City, CA)
Hope this helps some. JM

The old guys use to say the bigger size pumps for bigger tractors. Over the years I have seen all combinations of big BeGe's on smaller tractor and little ones like this on bigger tractors. I want to say the type pump pictured if in very good condition will be as high as 1200 PSI. With normal wear 8 to 900 PSI is more normal. The larger BeGe's are more like 1000 PSI brand new and as low as 6 to 800 with normal wear.

It is interesting how many people forget that drive turns the other way on some of the Cats.

Hopefully Associated Tractor has a source of drive couplings that fit the Cat pto. That has always been my biggest problem was finding a coupling. As the drive shaft itself any good machinist can make if you have the coupling. I even have mounting bracket that was built by a local guy for me.

A “trick” I noticed, if the “eye” on the pump is positioned down, it was from a D6! If it is on top, it was from a D4! Fair warning: BeGe’s used paper thin gaskets and zero lock washers!
I had a friend needing a seal for a 1200? SWECO had nothing, and from memory, an unobtainium item. Surprised to learn Associated actually had one. Go figure! JM

yes if you have the proper power take off gear box as found on ag tractors it makes things easier as it will allow you to select when it is actually running this reduces wear on the pump (why run it when your not using the remotes). the pto box has the standard 540 rpm pto spline shaft.

so it would be easy to get a coupler made to suit that as they are a standard pattern and available as a flange that you could bolt or weld the other half that suits the pump. my preference would be a semi flexible coupling to take out shock load and any slight misalignment so you dont snap something

the u series tractors did have a diverter valve but you could only use one attachment at a time. so that is another option.

instead of perfection some times we just have to accept practicality

If you want to spend the change Associated will build a new 1200 or 1400 unit. I know of one about 5 or 6 years old near here. So they must have the seals.

I have been playing with BeGe pumps since the 1970's up to 2000 and never found a off the shelf coupler that fit the Cat rear drive shaft for a RD 6 or D6 8u,9u tractors. Been told the D4 is not around ether but never really hunted for one of those. The shaft in the rear of the Cats is not the same as a 540 PTO shaft. It has different splines and the shaft size is different as well.

BeGe had their own clutch that fits their mounting hardware. It could be adapted to other things but would all be custom machined . No flex couplings I have ever seen in mounting hydridic pumps on the rear of crawlers. I can see it's advantages but have never seen it done. I have put together 3 front mounted pumps on 9u's . All have used universal joints so aliment did not have to be 100%.

Dealing with more modern tillage equipment it was cheaper to put together a higher pressure system than put bigger diameter rams on the equipment.

Associated used to have plenty of the shafts.
Unless the OP is luckier than most, he can have close to $500 into it before bolting it to the machine.
Same here, I buy BE GE units whenever available. If I was closer to the one he posted, It would have been scooped up. The longer supply tube is hard to source used, so his is a good price even if it lacks parts. JM

Wide body 650 pumps will only work on an old D8 RD6 D7 they will boil and run hot on a D6 with a high speed engine I found that out the hard way 17afarmer

I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
