684

Iron Appraiser · Jun 22, 2010

I changed the oil in the transmission of my International 684. I refilled the transmission and now the pump does not pick up the oil. I have no hydraulics what so ever. The pump was replaced less within the past 100 hours with no problems after the replacement. Any ideas would be appreciated.

First are you sure the filter and screen were installed correctly?
To Prime hydraulic pump, first try pressurizing the transmission by putting an air gun in the dip stick hole.
If that dose not work turn tractor off, place a clean bucket under the MCV valve, loosen the hydraulic line (power steering pressure) on bottom left of MCV valve, start tractor and run engine at fast idle until hydraulic oil comes out. Shut engine off and reconnect PS line.

On our 584 I have to let the tractor idle and cycle the steering wheel back and forth slowly several times until I feel some resistance in the wheel and it slowly primes and begins to turn the wheels. That seems the nature of the beasts. Sometimes I have to give it a fast idle to get it cycling through.
