All RaceTec™ parts are made with high quality machines and tools, including diamond turned ring grooves and. You can make the rings slightly oversize to allow for a worn bore, but you MUST set the ring gap in the least worn section of the bore to prevent breakage from insufficient clearance. Ring gap should be on that side of cylinder where compression forces cause the bigger side-pressure for the piston/cylinder wall. These equations do not consider the ring end gap and ovality, gas pressure acting on it, nor the actual bore shape, but only the maximum amplitude for a given term (from a F. If you run out of gap the piston seizes. The build uses the same end gap for the second ring as the top ring.

A piston ring must provide a predictable and positive radial fit between the cylinder wall and the running surface of. 004 per bore inch is optimal to prevent cylinder wall scoring and blow by gasses. Plasma-Moly Standard Gap Ring Sets are listed by bore diameter and list available over-sizes. Take a piston with no rings on it, turn it upside down in the bore and use it to square the ring in the bore. Otherwise the ring will bind due to expansion when it gets up to operating temperature. Skirts come teflon coated for maximum piston longevity. The second ring end gap should always be larger than the top ring end gap. Rocky Mountain ATV/MC carries all the tools and OEM and aftermarket parts you need to rebuild the top end on your machine. Calculate the recommended ring end gap from the chart (Figure 1). Supercharged and turbocharged engines tend to do this to protect the rings from excessive heat. The reason for it is so that anything that gets past the top ring won't get trapped. This can deviate from what's on the label of the insert box when the piston height of your engine is different from what's stated on the same label. The ring end gap depends a lot on how the heat transfers from the top of the piston to the top and second ring and how close the rings are to the top of pistons and valve reliefs and it doesn't matter if the piston is forged or not it depends what has been added to the aluminum. The last ring is called the oil ring. Measure end gap with feeler gauge. See table below for proper ring end gap for your application. Position the ring at right angles to the cylinder wall by gently pressing it down with a piston. If the bore is beyond the service limit, the engine block must be rebored. Ring end gap also is a good way to tell ring wear. 3) Too much ring gap will allow more blow-by, but theoretically, I could have a huge ring gap on a new ring and the only negative would blow-by (which could cause the piston to seize. The ring gap should be around 0. It also graphs the field strength (for the portion of the. Multiplying this 0. Those are a Mahle piston ring that Raisin was talking about there. A rule of thumb for ring end gap measurement is to use the bore size in inches x. Piston rings are usually made of high-quality gray iron.
