4010 hyd pump noise without load

c.w n.y · Sep 9, 2018

looking for some help with My 4010. The hyd pump knocks/rattles loudly when no hyd function is engaged once a function is engaged the noise goes away.

You need to install a 4020 coupling, unless it's already been
replaced. If that's the case you need the bushings.

Ditto check hyd pump drive coupler for wear or cracked disk if original style coupler.
