Tightening regulations for expansion bolts on HP-accumulator:
1. Treat the threads of the expansion bolts and the threaded inserts with Anti-Seize agent.
2. Treat the surfaces between the expansion bolt head, washer, and HP-accumulator cover with Anti-Seize agent.
3. Place on the HP-accumulator, and tighten the expansion bolts by hand in a crosswise fashion.
4. Pretighten the expansion bolts to
HB 5800/DP from SN 49 to 169 = 100 Nm
HB 5800/DP from SN 170 = 80 Nm
HB 7000/DP from SN 169 to 269 = 100 Nm
HB 7000/DP from SN 270 = 80 Nm
HB 10000/DP = 120 Nm, proceeding in a crosswise fashion.
5. Tighten each expansion bolt through 30° in a crosswise fashion.
6. Finally tighten each expansion bolt again through 60° in a crosswise fashion.
