Update of the instruction for piston clean-ing ring Replacement of SL2016-620/AAB
It has come to our attention that misunderstandings have occured re-garding piston cleaning ring (PC ring) replacement when a liner is worn.
The PC ring replacement instruction has therefore been updated. The piston cleaning ring is installed to protect against excessive deposit build-up on the piston crown top land by scraping off the deposits when the piston approaches top dead center (TDC).
If deposits build up excessively on the top-land of the piston crown, it can have a negative influence on the cylinder condition. It is therefore not recommended to operate the engine without the PC ring installed.
