Abstract: A system is provided to protect drilling fluid processing equipment from damage in shipment and in installation and operation at the work site. The drilling fluid processing equipment in the preferred embodiment of the invention consists of a pump with an elongated drive shaft supported only by bearings at the motor end, leaving the shaft housing vulnerable to bending. The pump is rotated about a support bar on a skid unit causing the elongated drive shaft and shaft housing to be lowered through an opening in the skid unit to the operating position. The pump may be inspected and/or repaired by rotating it upward through the opening. The length of shaft and shaft housing that extends through the opening may be adjusted by changing the point of rotation of the pump about the support bar.
