Yep, something about hindsight. I知 kicking myself in the butt. Should have had a hydraulic shop size them for me. Good news is that getting the control body out isn稚 that difficult. I replaced the o rings in my dozer a couple of years ago and it required hoists boards etc. just to get that heavy thing out.

haha, ya live and ya learn. I can only imagine the weight of a giant cast piece in a dozer. That's probably definitely the limit factory once you get in to heavy equipment. Hopefully you get your unit sealed back up shortly; there's not much to them at all.

Here y'all go. The exact part number I used.
Item Number: 2-210 N70
Description: 70 DURO BUNA N O-RING

Item Number: 2-116 N70
Description: 70 DURO BUNA N O-RING

You can probably good that and confirm the specs with what i measured originally just to make sure. But maybe that help someone.
