Inner Sleeve & Rack Bar

1. Install new backing ring and piston ring to piston. Ensure it moves freely in its groove.
2. Place a new seal retaining cap over rack teeth, with three tabs facing away from piston.
3. Install new split bearing in recess in inner sleeve, ensure it is seated properly.
4. To protect new inner sleeve seal from being damaged by rack teeth, cover rack teeth with a piece of plastic adhesive tape.
5. Carefully slide seal, with recessed face towards piston, over tape and onto rack bar. Remove tape.
6. Install a new O-ring in its recess in inner sleeve. Ensure it seats correctly.
7. Ensure ends of split baring are on opposite side of rack bar to teeth and push inner sleeve along rack bar. Carefully push seal up against retaining cap and in turn, against piston.
8. Ensure inner sleeve is square to piston, continue pushing until seal is fully in place.
9. Maintain pressure against piston and neatly bend three tangs into groove on outside of inner sleeve, securing retaining cap.
10. Apply a smear of silicone to bore of new square section sealing ring. Install nylon backing washer and sealing ring into bore of rack tube. Slide down until they contact pinion end main housing.
11. Assemble rack bar, with inner sleeve still against piston, into rack tube bore. Guide piston ring into rack tube bore. Continue sliding rack and inner sleeve assembly into rack tube bore, until inner sleeve enters sealing ring and seats firmly against pinion end rack housing.
12. Look into hexagon socket screw hole and ensure retaining shoulder has passed the hole. Install sealing washer and socket grub screw.
