DATA - IDENTIFICATION PISTONS - PISTON RINGS

1 - PISTONS

Reference (A) : R1 For repair dimension pistons .

Reference (B) : Marking towards the timing gear .

Reference (C) : Identification of pistons .

Reference (D) : Category identification for matching with the liner (3 grades) .

WARNING : the pistons are supplied fitted with their gudgeon pin; as the two components are matched, do not mix the pistons and the gudgeon pins .
