Engine Coolant Inside R53 Superchargers PTO………………?

This is a very rare case (we currently have seen around 5 cases ) where the waterpumps seal fails and coolant forces its way into the Superchargers PTO ….

The water pump and PTOs mating surfaces corrode together making a seal….. so the coolant may not even be coolant dripping on the floor at all.

This is the only incident where we’ve seen the coolant get through the second oil seal in the PTO (under small gear) and into the rotor housing..

Not to worry this SC went under GTT Spec PTO Plus Supercharger Rebuild

The seal behind the fork drive is also replaced during a GTT PTO rebuild. We also strongly recommend a new water pump is fitted at the same time.
