U-Joint Needed for Hydraulic Pump on 9U-D6

If you find someone who knows what they are doing at Napa. They can match it up for you.

U-joint is an old number UJ934....look up the cross over numbers.
Yoke 5F8501 is an old "Blood Bros #3NF5". Neither the company or the yokes seem to exist any more.

Thanks "Old Magnet" for your reply. I went back to my machine and looked at it real close, and then I looked in the No. 46 Hydraulic Control Parts Catalog. On page 58, it shows the 5F859 Mounting Group with two U-Joint numbers: #5F1083 and #6F4339. On page 72, it shows the breakdown of #5F1083. My parts book doesn't show #UJ934. My book does have the same yoke number you have. My "center" is warn from the outside of the yoke hitting the outside of the "center". I can use them, but it would be nice to have a new ones. The "center" is #5F8500 in my book. Where do I find cross-over part numbers? Do you have any idea where I can find any of these parts or does anybody on here have any new or good used ones?

5F1083 crosses to Napa u-joint 934
6F4339 also crosses to Napa u-joint 934

And for 5F0859 check this link http://www.machinerytrader.com/list/partssearch.aspx?PartNum=5F0859+&btnPartSearch=Search&PST=Starts

As you've probably figured out by now the UJ934 is an aftermarket designation for the u-joint cross assembly where Cat lists individual pieces for cup, cross, seal, lube fitting etc.
Just google the UJ934 number for interchange options.
The rest looks like the best you can hope for is good used.

I have the coupling 5f1120 and the joint ass.in good condition and dimention total is 9 inchs

The 6F4339 joint assy. equals a 5F1083 assy.
These were manufactured by Blood Brothers Machine Co., predecessor to
Rockwell International as part #10220.

I can not find where an 5F1120 assy. is an interchange.

NPR shows both assemblies(6F4339 and 5F1120) to have been used in the same applications, both pipelayers. A 16A(583) from SN 1-300 and a 21A(572) from SN 1-331.

The 5f1120 coupling and joint ass are from 5f859 mounting group
