10. Replacement of toothed belt or CAS drive
10.1 Replacement of the toothed belt
The new toothed belt version must be used (Fig. ’E’), which can be ordered sepa-
rately as single part according to the Spare Parts Code Book.
Do not use the old toothed belt anymore.
10.2 Reasons for CAS drive replacement
There are two reasons which require a CAS drive overhaul:
− High shaft eccentricity: To verify the eccentricity, see the paragraph 9.3.
− Maintenance schedule: Work to be carried out at 48 000 operating hours.
Before carrying out the replacement of a CAS drive which is available as a stan-
dard spare part, a new CAS drive must be ordered unless a repair kit is available on
board.
The spare parts order number is to be found in the Spare Parts Code Book, Group
9, Chapter 9601 − 1, within item ’Crank Angle Sensor Unit’ and named ’Shaft en-
coder drive, complete’ or ’Shaft encoder, complete (box)’.
Remark! According to IACS regulations, at least one Shaft Encoder Package box
containing the spring balance is part of the standard spare parts supply per ship.
