Hello New to this Site and skid steers , I purchased a daewoo skid steer 1760 with a perkins 700 , That went on fire and I rebuilt the machine The fire dept put it out by installing water in everything . So Here is My issue That I left , I ran The Machine for seven Hours Plowing with a box blade . The machine drives perfect , But Has no lifting power . Slow Bucket . When I purchased the machine I notice that The aux hydralic pump was loose , I know That guy who I got it from Has another machine like it . Iam thinking he switched the pump Any Tips on How to check pressure \flow . Also He took the piolt releif valve which I replaced Thanks
