1. Measure dimensions A, B, and C on cleaned surfaces.
2. Calculate the compression (PD) and compare it with the permissible values in the follow-
ing table.
Product Compression PD [mm]
TPS44 -0.23 ... 0.23
TPS48 -0.23 ... 0.23
TPS52 -0.24 ... 0.24
Table34: Permitted nozzle ring compression PD
u If the calculated value (PD) lies outside the specified range, contact an ABB Turbochar-
ging Service Station.
