oil pressure too low for front loader

[DuncU.K.]

need some advice on the possible reasons for my TE20 not lifting a M.I.L.loader, when oil pressure to rear lift arms seems fine, ie - works well. the rams do pressurise when the valve is opened so oil is getting where it should but will not lift loader. have replaced relief valve and checked all pump valves and all seem fine, no oil leaks either!!
Very confused, help would be appreciated from someone who knows about these things!

You generally have to chain the lift arms down to be able to use the pump for external hydraulics. I"d suggest you get a shop manual so you can understand how the system works.

thanks for the tip, makes sense now. Thought it would be something simple, my w.shop manual only deals with hydraulic pump system for the rear arms, no mention of its effects on external hydraulics.

When you find and install a pump off the front pulley- or the pto, you will think you were lifting in the stone age! The pressure from the bolthole outlet 'can' opperate a loader, but when you -modernize? you will be amazed. Keep your eyes open for one.
