5.4.20.1 Precautions for Removal
1.
Remove the parallel pin using an appropriate tool.
2.
Insert bolts into the service holes, tighten the bolts, and separate the bearing head and the main
rotor casing flange face evenly.
5.4.20.2 Lifting of Bearing Head
Make sure that the lifting equipment and wires have sufficient loading capacity
for the compressor. Otherwise, the bearing head may fall, resulting in injuries and
damage to the compressor. Before lifting the compressor, always check that the
lifting equipment and wires have sufficient loading capacity. Do not allow anyone
to be under the lifted bearing head. (Bearing head weight: 168 kg for 170J, 270 kg
for 220J, 520 kg for 280J)
1.
Using the one eyebolt (M20/M30/M36) on the top of the bearing head, lift and carry the bearing
head with lifting equipment.
