It is Minneapolis-Moline's 'Uni-matic' hydraulic system.
The leak where the control lever goes on the shaft is an o-ring. But you have to take the lever off, and then take the cover off the opposite side of the tank and pull the lever out that way. Then change the 0-ring and reassemble. The plate where the hoses come out is sealed to the tank cover with o-rings that have a rectangular cross section. I don't have any luck with the replacement o-rings White offers, but a regular round o-ring from NAPA that fits the groove seems to work fine.
You don't say where the leak is at your cylinder. If it is the piston rod, I think a new seal is available. be sure your rod itself has a good finish on it. The best seal in the world won't help if your rod is rusty or pitted. I had to have a new rod made and fitted to my cylinder at a hydraulic shop.
Welters Farm Supply in Verona MO. is a good place for parts. They helped be with hydraulic parts for My BG.
