Still leaking oil into chaincase on a 631

[alexvbugman]

Changed out a drive motor for a new one on one side and resealed the other side, all was good till it got warm out and now it's filling chaincase again. Any ideas?

How are the drive motors sealed? is there a shaft seal? and is there a seal on the chain case between it and the motor?

No seal between chaincase, just on the shaft of the motor. I wonder if I'm not getting enough return out of the line?

Does the return go through the filter first?

I don't believe these moors had case drain filters, so there really isn't anything to block up to build up pressure in the motor to blow out a seal.
