6718 hydraulics

[jacob]

Hi Guys hope someone can help ? got a 6718 with very poor hydraulics,they drop and self correct a lot and also seem a bit limp on the lifting, could someone tell me where the filter and suction strainer and releif valve are? also a rough idea how the draft/position lever should be for draft or position work

hi to me it sounds like the rings on the ram inside the back lid,
there is a magnetic filter on the lid under the seat ,
the pressure valve is on the pump plate under the diff its round.

Thank you very much for your help , the lever behind the seat is upright would that be correct for position control work ie mowing?

"they drop and self correct a lot "

sounds like the ram is leaking to allow the links to drop then the position control senses theyve droped and raises them again to the set position... in position control nudging the lever up a tad should result in the links raising a tad.... theres a direct relation between the position of the lever and the actual height of the lower links.

What sort of job is it to replace the ram seals?
