A housing for a hydraulic actuator unit of a pallet truck is disclosed. The housing includes a lift motor mount for mounting a lift motor to the housing and a pump mount for mounting a hydraulic pump to the housing, and couples the pump to the lift motor when each are mounted. The housing includes a hydraulic cylinder with a cylinder rod, which is positioned based on the fluid level in the hydraulic cylinder; a reservoir to store fluid for actuation of the cylinder rod; and one or more fluid galleries that extend, internal to the housing, among the fluid reservoir, the pump mount, and the hydraulic cylinder. A traction motor mount mounts the traction motor, which is coupled to a steering unit of the pallet truck and controls actuation of a traction wheel of the pallet truck when the traction motor is mounted to the traction motor mount.
