Hydraulics
Posted: Sun Jun 16, 2019 5:35 pm
Hello all:
HELP!!
Im having trouble with the hydraulics on the 3 point linkage. I have a 750kg chipper that I plan to use on the major, it will lift the chipper up fine( 2200psi), but after the valve trips is looses pressure very quickly and the chipper slowly lowers. I have had the cylinder honed out and a brand new piston built to accommodate better model seals. I have also had the spool block apart and replaced every seal possible and had the relief valve re seated and more shims to increase pressure. What have I missed?
