Problem with my 4911

[mrbean]

I have had my 4911 for 4 years now and i have not had any problems before this year. First my 3p started jurking up and down and it rises and it falls down and so on.. I thought maby it was because there was to little oil and filled it a little over top line but its still tha same. Anybody who knows what this can be?
My other problem is the left brakes, when its cold i have pedal and the brake is free, but after driving a little it thigtens up and gets hot. Yesterday i had to drive a little long and i had to stop becouse it started to smell and there was smoke.
What do i have to do to get access to the brakes and is it a great job? Do i need any spesial tools?

For the 3pt lift, i think the O-rings of your lifting pistons are shot. they arent expensive.

For the brakes, try to drive backwards a few meters, it frees up sticking brakes. You also might have air or water in the brake oil. you can bleed them to see what happens.

Doc sounds correct on the o-rings part, but I think the brake problem could be the hand brake band, maybe linkage is siezing up?? it would be ok but eventually friction would warm it up and cause it to smoke

Det her problemet hres kjent ut. du m ta ut hydraulikk pumpa. den sitt fsta p et lokk under gearboksen helt bakerst mot trekkroken. ta ned lokket p kanten av det vill du finn et hull som passe med et lite rr som kj ned fra gearboksen der ligg det en o ring. hvis den e gen vil hydraulikken oppfr s som du beskrive.
