PROBLEM

Show/hide table

The exhaust bellows needs to be replaced on certain C175-16 Locomotive Engines. The existing bellow can fail its liner and get lodged in the turbine housing. The liner may cause a reverse flow through the compressor of the turbocharger and overheat the air filters to the point of combustion which may, in conjunction with other factors or circumstances, result in a risk of personal injury or death.
