After a few hundred hours, my 410 FEL finally has a leakdown in one of the lift hyd cylinders. The bucket will drop pretty quickly with a load in it and does make a weird sound in one of the lift cylinders when being raised. I guess its time to overhaul the bad cylinder. Would it be wise to do both while I am at it? And does anyone have a breakdown schematic of the lift cylinder or know where I can get one.
