Do you file the oil ring?
“On the oil ring rail supports you just want to make sure there’s at least a . 015-inch gap”, says Meagher. “If you find you have to file the oil rail, you might have the wrong ring in the box, because very rarely do you need to file the correct oil rail”.
How should the oil ring expander be installed?
Installation. The expander portion of the oil control rings should be the first piece that you install. It goes into the 3rd groove of the piston. Our expanders are designed so that they do not overlap and are very simple to install.
What is the purpose of compression ring and oil control ring?
The top two rings— known as compression rings— are primarily for sealing the combustion chamber. The bottom ring— known as the oil control ring— is primarily for controlling the supply of oil to the cylinder wall, in order to lubricate the piston skirt and the oil control rings.
Do you GAP oil rings?
The oil rings only needed to be checked to ensure they were greater than 0.015 inches. The oil scraper ring does not need to be gapped. Once you have all the rings gapped to the correct settings for their assigned cylinder bore, weigh the set and record the value.
How do I reduce the tension on my piston rings?
“For dry sump, you can run a lower tension oil ring because there’s going to be less oil from the windage splashing it around in the motor.” “The vacuum will let you reduce the ring tension. That’s because you’re going to have less atmospheric pressure in the crankcase,” adds Massingill.
What does the oil expander ring do?
The expander can be thought of as a spring that is loaded when installed in combination with the upper and lower oil rings. The oil rings’ function is to scrape oil off the cylinder wall and push it inward to oil return holes or slots cut on the inside of the piston’s oil ring groove.
Do you oil piston rings before installing?
You don’t need to drench the piston in oil—use enough to lubricate the rings as they pass through the piston ring compressor. No need to dunk the piston and ring assembly in a quart of oil!
Can you file down piston rings?
Use a ring squaring tool to seat the piston ring squarely in the bore, and a feeler gauge to check its gap. Check the gap often and grind slowly to prevent ruining the ring. When filing the rings, sneak up on the final gap. Go slowly, removing minimal material at a time and re-checking the gap often.
