Leaking hydrostatic drain plug

[bobaloo22]

The right rear plug on my b7800 has a small drip, about one drop every 36 hours. I pullEd The drain plug and the washer is steel with an o ring, o ring was shot. Is this the factory Kubota washer? It’s been several years since I’ve changed the hydraulic fluid and can’t remember. Thanks for the help,
Bob

That sounds like a standard elastomeric BSPP sealing washer. Nothing Kubota specific about it. If the rubber portion is damaged you need a new one.

Yes, but I was wondering if this is a standard kubota item. I can get 10 for the price of one at the dealer. I was told that it used a copper crush washer but I don’t believe that is correct.

This is what Messicks would supply.

Ummmmm, which right rear plug?

The washer @TheOldHokie pointed to is on the side of the case.

These are on the right and left rear axle cases and mid PTO

I’m sorry but I thought the thread title saying leaking hydrostatic drain plug would be enough info for the location of the leaking. I’m just trying to clarify if this is the correct washer. i know there are three drain plugs and it’s the right (starboard)one. Yes Wolfie that appears to be the exact one that I have Thank you

All you need to know is what size pipe plug.
