Service Letter
June 2002
Check of Camshaft Coupling Fitted Bolts
All engine types
Action Code: IMMEDIATELY
Dear Sirs
As we occasionally still see cases of broken camshaft coupling bolts, we have
decided to update our “Checking and Maintenance Schedules” and introduce an
annual check of these bolts.
A Service Letter, ref. SL99-368/CBO , dealing with this subject, was issued in 1999.
However, in view of the consequences for the vessel in the event of a failure, we wish
to emphasize the importance of a regular check of these coupling bolts, as part of the
standard checking procedures applicable throughout the lifetime of the engine.
For your information we enclose an example of our standard Checking and
Maintenance Schedule (No. 900-1) specifying a survey every 8000 hrs.
For your easy reference, we also enclose our instruction No. S906-4 which, for future
plants, will be adapted to the specific engine type.
Questions or comments regarding this SL should be directed to our Dept. 4100.
Yours faithfully
MAN B&W Diesel A/S
