Shouldn't a new control valve with center neutral on the levers
hold  a load on the cylinders without sagging?  Maybe all my cylinders
have  blown gaskets and are leaking. Do you think this could happen to
all of  them at once from the water? There are four fairly large cylinders
on this  loader - two for the lift and two for the bucket.

Any  comments from anyone who works on his own hydraulics would
be  appreciated.

The "leathers" are probably chevron V packings.  If these cylinders  are 
double acting, the oil is leaking past the packings and just filing up the  rod 
end.  Since there is room for the oil on the rod end of the cylinder,  you don't 
notice any going back to the sump.  We have a company   called Sealco here in 
OKC that has packings for all sizes of cylinders..   Usually what a dealer 
wants $100 for we can get for about $10.  I started  replacing cylinder packings 
in loaders back in 1967 when I worked in the MF  dealership....   If you have 
a big workbench and a large well mounted  vice, and an impact wrench, it is 
not a bad job.....
