An improvement in a pump-down tool for use in sand washing operations is provided. The pump-down tool includes a tubular member having a locomotive member positioned thereabout and a fluid passageway positioned therethrough and a sand washing tool positioned in fluid communication with the lower end of the tubular member as positioned for use. The well has positioned therein a first and second tubing member with the first and second tubing members being in fluid communication at a junction near their lower ends so that the pump-down tool may be urged along the length of the first tubing member toward the junction by pumping fluid sequentially through the first tubing member, the junction and the second tubing member. The tool is recovered by pumping fluid in the opposite direction. The improvement comprises; positioning a slideably mounted locomotive means about the lower portion of the sand washing tool as positioned for use with the locomotive means including means for positioning the sand washing tool at an angle of up to about 5 DEG from the axis of the first tubing member.
