1	Press the ball bearing (14) into the leadscrew housing (1) using a vice or press.
2	Press the clearance washer (larger ID) of the thrust bearing (15) into the housing using a vice or press. A piece of rod or tube will be required to press on the surface of the washer. Ensure the washer is orientated so the grooves are exposed.
3	Insert the leadscrew (16) into the housing so that ball bearing sits against the shoulder of the leadscrew.
