20. NOTE: If a cap-type ball return guide is used, remove and discard the two special sealing screws that fasten the cap to the piston.
Remove the cap and the cap seal and discard the seal.
21. NOTE: Left ball return guide halves are copper-plated for identification and right guides are not plated.
NOTE: Make sure the rack piston is on a cloth so the steel balls that fall out won't roll very far.
Remove the ball return guide halves by carefully inserting a screwdriver between the rack piston and the guides.
22. CAUTION: The steel balls are a matched set. If any are lost, the set must be replaced by service balls. Number of factory balls installed:
TAS40-32.
Remove the steel balls from the rack piston by rotating the input shaft, valve and worm assembly until the balls fall out.
-
Place the balls and return guides in a cup or other container and make sure all the balls have been removed.
