HydraDrive Seals

Post by **jkelm24** » Wed Dec 14, 2016 11:31 pm

Looking to rebuild a Hydra Drive, but rebuild kits are rare and expensive. Does anyone know the ID / OD measurements of the internal seals?

Thanks!
Jon

Jon,

What is classified as expensive for the rebuild kit? Just interested to know....

I've only seen one come up recently and it was bundled with a housing kit to make a full Hydra unit. The price was > $45 for both. I'd prefer to spend a couple bucks on a seal.

I don't know the size off-hand, but they are generic quad seal o-rings, commonly available.
