So after about a month of good performance, the hydraulic levers cause the contactor to click but no lift, tilt, or sideshift. Operator reported lift was SLOWING down and making noise as it went. Then stopped.

Took up the floor covers and nudged the pump motor fan with a plastic pointer - motor starts but arcs (that's the noise heard when it slowed). Pretty sure its brushes hanging up.

Looks like they can maybe be changed with motor in place? Any guidance very welcome. Thanks.
