Pump Bearing → Water Guide Bearing → Interference Press Fit

The guide bearing of the full cylinder water pump can be installed by freezing or pressure: 

  • Due to the high thermal expansion coefficient of INDRON® materials, it is recommended to give priority to installation by freezing (liquid ammonia or dry ice); 

When the tooling conditions for installation by freezing are not available, pressure installation can be optional (INDRON® bearing needs to be chamfered as required then).
