Re: MAK 43 Cylinder head stud failures

Dear JW,

 

Usually cylinder head stud bolts will crack in the first lower thread caused by corrosion. This happens when water was spread over the engine.

 

Kind regards, Zement

Dear JW,

 

Could you please give us more information on the engines, like serial number etc.

This would help to create a response for you.

Best regards

MAK 43 Cylinder head stud failures

The plant I am in is having a very high rate of cylinder head studs failure around 32 last year. Has anyone else had this type of trouble? The trends before showed that this plant normally broke around 5 a year since the start up of the plant, but last year the units had around 45k hours and the failure rate changed.
