1. Lubricate new seal (Figure 7, Item 4) with clean hydraulic oil and install in cylinder head (Figure 7, Item 7).
2. Lubricate new seal (Figure 7, Item 5) with clean hydraulic oil and install in cylinder head (Figure 7, Item 7). Seal
lips must be toward small end of the cylinder head.
3. Lubricate new seal (Figure 7, Item 6) with clean hydraulic oil and install in the cylinder head (Figure 7, Item 7).
The seal lips must be toward large end of cylinder head.
4. Lubricate washer (Figure 7, Item 3) with clean hydraulic oil and install in groove on outside of cylinder head
(Figure 7, Item 7). Install washer with flat side toward large end of cylinder head.
5. Lubricate new O-ring (Figure 7, Item 8) with clean hydraulic oil and install in groove next to washer (Figure 7,
Item 3) on outside of cylinder head (Figure 7, Item 7).
6. Lubricate bore of cylinder head (Figure 7, Item 7) with clean hydraulic oil.
7. Push cylinder head (Figure 7, Item 7) onto piston rod (Figure 7, Item 13). If cylinder head will not slide easily
onto piston rod, a soft hammer may be used.
8. Place a support below and near end of piston rod (Figure 7, Item 13) to prevent damage to piston rod.
9. Install piston (Figure 7, Item 11) on end of piston rod (Figure 7, Item 13).
WARN I N G
Use caution when using adhesives and sealants. Prolonged inhalation of vapors can
cause lung irritation. Contact with skin can cause dermatitis. Wear gloves and safety
goggles and use product in a well-ventilated area away from open flame. If ingested, keep

10. Apply sealing compound to piston rod threads, 1/4 in. from open end of piston rod. Apply 1/2 in. of sealing
compound to piston rod threads.
11. Install nut (Figure 7, Item 12) on piston rod (Figure 7, Item 13) and torque to 270 to 346 lb-ft (365 to 469 Nm).
12. Lubricate new seal (Figure 7, Item 9) with clean hydraulic oil and install in center groove on outside of piston
(Figure 7, Item 11).
13. Lubricate new wear ring (Figure 7, Item 10) with clean hydraulic oil and install in end groove on opposite end of
piston (Figure 7, Item 11).
14. Lubricate inside of lift cylinder (Figure 7, Item 1) and piston (Figure 7, Item 11) with clean hydraulic oil.
15. Push lift cylinder (Figure 7, Item 1) straight onto piston (Figure 7, Item 11).
16. Start lift cylinder (Figure 7, Item 1) onto piston rod (Figure 7, Item 13) assembly.
17. When piston (Figure 7, Item 11) is in smooth part of lift cylinder (Figure 7, Item 1), start cylinder head (Figure 7,
Item 7) into lift cylinder.
18. Lubricate O-ring (Figure 7, Item 8) on cylinder head (Figure 7, Item 7) with clean hydraulic oil.
19. Tighten cylinder head (Figure 7, Item 7) to 300 50 lb-ft (407 68 Nm).
20. Install two fittings (Figure 7, Item 2) on lift cylinder (Figure 7, Item 1).
