Who are the manufacturers of engine piston rings?
2.5 Million Vehicle Applications. 1 Well-Earned Reputation. At Hastings, we manufacture a bold and broad offering of piston rings—one that spans thousands of applications for virtually any engine.
How big are the bores on a piston ring?
Our rings function in sets, usually—a top compression ring, second groove compression (or oil scraper) ring, and oil control ring—and range from 1.125″ to 8.875″ bores. If you’re questioning the set you need, our engineers can recommend the right one out of the thousands we offer. Learn more about the piston rings we manufacture below.
What kind of ring does a diesel engine use?
Primarily used in diesel applications, the Full/Half Keystone type prevents carbon build up and ring sticking. It also creates additional surface area for side load bearing. Coatings include: Chrome, Ceramic Chrome, and PVD. Rectangular type has no ID bevel.
What kind of coating is used on piston rings?
Coatings include: Plasma Moly, Chrome Manganese Phosphate, or Ceramic PVD. This ring type is trusted for increased gas side sealing and better oil control. It may have barrel or straight face. Coatings include: Manganese Phosphate, Chrome and Plasma Moly.
What are the dimensions of a KTM 300 piston?
Ring Gaps – top ring 0.64mm second ring 0.49mm ( Max tolerance on both should be 0.40mm max ) Bore I.D. – 72.009mm ( On the high side for piston type 1, but still within spec – 72.000mm – 72.012mm ) ( Piston type 2 specs are 72.013mm – 72.025mm )
How big is the exhaust gap on a KTM 300?
Sorted it today, installed group 1 piston, new ring gap was .30mm which is pretty good, Re adjusted the exhaust valve height which was at 49 mm ( pretty low )set it back to 46mm as per factory setting, mixed and matched base gaskets to get .00mm deck height.

What is the function of the top compression ring?
Top compression rings (UCRs – upper compression rings) control combustion chamber gases allowing the piston to transfer the energy of the expanding combustion gases, to the crankshaft. These rings also play a major role in the heat transfer process between the piston and cylinder wall.
What happens to the marriage between piston rings and cylinder wall?
If the piston were removed from the cylinder at this time, the result would be that we disturbed the marriage between the piston rings and the cylinder wall, which is a result of proper engine break-in and which we know has occurred when the engine oil consumption stabilizes.
When do the piston rings bedded in in a car?
Therefore, I assumed the engine was beyond the normal break-in period of, say, 25 to 50 hours. Given that, I also assumed that if this was the case, then the piston rings would have been seated or bedded in and the oil consumption stabilized.
How does a ridge reamer remove piston rings?
The ridge reamer is a cutting tool that will equally cut around the very top edge of the cylinder to remove the ridge. The ridge is formed naturally as the area of piston and ring travel in the cylinder wears and the portion above it does not.
