After noticing a few leaks and then a pipe splitting I removed the loader from my 844xl so I could get all the hydraulics sorted. Several pipes and filters later I am now looking to put the loader back on.
I have some questions about the pipework. I know next to nothing about loaders, I’ve put the pipes back on as they previously were;
b1 comes from the hydraulic pump
T1 returns the the auxiliary tank
the previous owners had another pipe running from the T outlet (below t1) to the drain plug at the back end of the tractor. Is this the free flow pipe? Do I need to have it or can I just close off the outlet? What’s the advantages of a free flow pipe?
I only ask as someone is telling me I don’t need to re-install it, I’m not convinced but want to understand it first.
I don’t know what make the spool block is, the plate has worn away and the serial numbers haven’t been fruitful after a Google search.
