I have a L402 Hydraulic issue,Issue is that there is zero action from any of the controls either the front bucket or the 3 point linkage,this is intermittent ie hydraulics work fine then after tractor sits for a few days the hyd dont work then next time i start it it is fine,appears there is a sticking valve somewhere can someone please point me in the right direction to find this valve or possibly a link to the hyd schematic.thanks in advance.

google is not helping as usual ....Have you cleaned the Hydro oil screen?

If its like a b7100...or similar...be damn carefull putting it back in or you will have a mess.,

Pics of tractor would help......look for the suction line ( bigger of the 2) and see where it connects to trans . or wherever.

L402 I am guessing is your loader model number, what model tractor do you have?

It has a spin on hyd filter just above the pump.
