Bobcat 753 hydrostatic drive motor

[vewe]

We are in Greece and had hydraulic oil going from the drive motors to the drive train. We took out both motors and replaced all the seals with the sealkit. We replaced the bearing in the drive train. When we assembly the drivemotor and fix the geroler and balls. We could assembly it with hydraulic oil between the geroler and balls. After it was not possible to rotate the pump by hand using the drive. Is this normal or not. Thanks for helping

I build the motors in the Bobcat and it runs perfect. It looks that it is not possible to turn the motors by hand.

Totally normal, a good motor will not allow you to turn it by hand, if you use a wrench it will, but normally it will not if the internals are not worn.
Glad they worked after you rebuilt them.
