As described in our Diesel Customer Information Cus 190 02/02, the
corresponding crank pins are to be checked for ridge wear whenever big-
end bearings are checked and/or replaced. If necessary, the crank pins
are to be refinished accordingly.
Nevertheless, we lately were informed that technical irregularities were
occasionally noted even though refinishing work had been carried out by
the customer’s skilled personnel.
In order to ensure safe running-in of the big-end bearing shells, we ur-
gently recommend to have the corresponding check and possibly re-
quired refinishing work carried out by qualified specialists of MAN B&W
Diesel only, by means of the corresponding tools, every time a big-end
bearing is replaced.
After refinishing a crank pin, it is absolutely necessary to install a new
big-end bearing (upper and lower shell).
In case you have any questions, please contact our Technical Service in
Augsburg.
