unimog u1000 & freeflow return

[Goaty]

there must be a return fitted my 900 has one at front and one rear

 

A freeflow return is a larger coupling and wider bore pipe it can return higher flow rates returning from implement. It prevents build up of pressure which stresses levers etc and leads to leaks. Its simply a mains style drain. If you use ordinary return through spool valve you get build up of back pressure,

"She's gonna blow!" scenario. I was unaware of them until last year. It rarely comes as standard on tractors ,but modern high flow hydraulic kit can cause tractor constipation of sorts.

on my u1250 theres a connectine straight to the hydraulic tank. altho this goes threw the filter so is slightly restricted.

 

my post chapper works fine of the spool valves tho

they are very simple to fit locate the spool block and locate the pipe that goes direct to the oil tank it may go through a fillter ( if there is tap in before the fillter) all you have to do is to take of one of the ends of this pipe and in cert a t pice and conect the concotor to this it shoud cost about 30 quid + any pipe that is needed
