**Spring Loaded Conformable Scraper - above gudgeon pin.Internally Stepped Compression - third groove.*Internally Stepped Compression - second groove.Chrome Insert Barrel Faced Compression - top groove.When fitting sealed power rings, ensure that the ends of the spring loaded segment butt together and do not overlap.**Some earlier A4.248 engines had a sealed power scraper ring fitted in the 4th groove. *On some earlier A4.248 engines rated up to 2,000 rev/min, the second compression ring is plain cast iron.Some later engines, rated up to 2,000 rev/min, have internally stepped chrome faced rings in both 2nd and 3rd grooves.When fitting internally stepped compression rings, ensure that the step is towards the piston crown.When fitting the spring loaded conformable scraper ring, ensure that the latch pin enters both ends of the spring. With the ring gap diametrically opposite to the latch pin, position the oil control ring over spring correctly located in annular groove of ring, i.e., between the oil control ring and the bottom of the ring groove in the piston.(c) 4.248 Engines (3 Ring)

This plain ring is completely interchangeable with the earlier chrome faced ring. When overhauling combine engines, the later plain ring should always be fitted (in engine sets).
