In April I rebuilt the hydraulic pump in my 52'8N. Since its been woking great, lifts higher and stronger than ever before. A couple days ago it just quit. It will raise with no load, but hook to something and the lifting stops as soon as the load is encountered. Any ideas on what has happened?

I'm gonna guess a gasket or a relief blew out.

The fact that it lifts under no load confirms that the pump is moving -some- oil.

Pull the side cover and load the lift and put it in the raise mode.. see where the oil squirts from.

Could be pump body gaskets.. standpipe / top cover gasket.. or even a blown oring on the piston, if the cylinder was scored, or there was a tear or imperfection.. or it simply didn't seat well.

Relief valve could have busted open.. etc.
