I’m trying to run the vac on Kinze corn planter with precision planting vac meters. Every time I turn vac SCV on, oil spews out of fan shroud. Rebuilt seals in vac and it did it again almost immediately. Case drain is hooked up, how can I check to make sure it’s working. Trying to eliminate possible issues so I can get to planting some corn. Thanks
Case drain or motor return? They're different.
Try just hooking your vac motor pressure hose to the right side scv coupler, and the return hose to the left side scv coupler. You will then push the scv button forward to detent to run the vac fan motor, and push the button to float to shut it down correctly. If you truly have a third hose, it will be a case drain, and that should go into the sump drain/case drain port, not the motor return port.
This is what my 8100 looks like.
