Hi everyone,

I have a problem with my fadal pallet changer on a 96 4020. The clamp pump has stopped working. The oil cup ran low while it was turned off with air connected and the pneumatic pump must have cycled through the night. I took the pump apart and it seems to be able to function fine. When I put the air line on, I use to hear a thumping for about 5 sec while the pneumatic pump locked the pallet into place. Now it does not thump. I am open to suggestions.

Thank you
