O-ring kit for hydraulic control panel knobs?

[Awesomeness]

On my hydraulic control panel, the knob that selects cab/tire/suspension has started to leak hydraulic oil. The manuals have some exploded diagrams that show the knobs come out with a bunch of little o-rings on them. Are there kits to replace them all?

Does the tm show part numbers for the individual o rings? If so they are usually spx parts.

What does SPX mean?

The exploded diagram is in the LMTV parts manual. In the maintenance manual all I have found so far is how to change out the entire assembly (but it might be in there somewhere).

SPX is a company.

I believe that panel and valves are made by Parker. They should use standard sized hydraulic orings and seals.

Oh boy! This sounds like another fun episode of "Guess That O-Ring"!

Working in industry, o-rings like seals and bearings are more or less standard for size. When it comes to o rings the biggest difference is what they are made our of. EPDM, Viton, Silicone, Buna-N, PTFE, FEP, Neoprene, Kalrez, ect...

If you have one in hand you can go to a place like McMaster Carr's website and go from there. With the width and ID you can get the dash number. You can also use something like this https://www.amazon.com/O-Ring-Sizing-Gauge-Plastic-Blue/dp/B012D6G13S
