Bobcat 773 Auxiliary Hydraulics Problem

Andy Martin · Dec 9, 2015

Today my grapple started closing between loads. It started getting worse within an hour, the grapple will close in about three minutes under gravity. It also does not seem to hold pressure on the closed position. I'm trying to follow the hydraulic schematic, but need some help. I figure it is not a worn spool or it would not get worse quickly. I'm hoping it's debris in a relief valve or an internal o-ring leaking. It's got about 2,400 hours on it, with a Kubota diesel.

Are your sure that grapple's cylinders are not bypassing oil around the piston? Your problem might not be with the machine at all.
