Need help identifying/repairing leaky Eaton hydraulic motor with missing ID tag

[bigdeano]

Not so......the cross section of the charlynn seals on the housing sections are smaller, squishing orings does not work and will only cause premature failure, more than likely the last guy to repair this hyd motor did just that.
Fix it once.....Fix it right

OK, if they've used a proprietary size seal so they can charge a fortune for them, then an O ring probably won't work. The cylinders on a Case backhoe I had were like that, the seals were all weird size. I re-machined the parts to standard size.
