I’ve looked through some of the books I have and I’m not able to identity the cylinders I have I also did a google search and the show up as a John Deere number? But look like every other cat cylinder

I think you included a picture my computer is not wanting to open. So a little more detail of what you are cross referencing would help me a lot.

Hi,

maybe a description of what this cylinder does on your D4 7U. Kinda looks like it could be a No 4 Tool Bar cylinder??

If it is, most any decent hydraulic supply shop should be able to help you out at a guess.

Cheers,

Eddie B.

Not sure about this case, but generally the casting number is not the part number.

Taking what edb said if we have a copy of D4 tool bar equipment in the library here you could look for a part number there.

But I have had good luck with hydraulic supply house measuring the old seals and mostly have them in stock.

The 4H6711 cast in the part is the cylinder group number. Npr says it applies to D2 and D4 tool bar serial numbers 71C 72C 73C 74C So a parts book for these tool bars should should provide info.
