Krush Groove was created in 1984.
Into the Groove was created on 1985-07-23.
Feel the Groove was created in 1991-01.
The duration of Spy Groove is 1800.0 seconds.
I can't tell for sure because I haven't been able to find a clear enough close-up, but it bears a striking resemblance to the class ring of Texas A&M University. The clearest shot I've been able to find of her ring appears to show the same shield crest in the center and the cannon/rifle/sabre emblem on the side of the ring. The groove running around the edges of the ring is identical to the edge found on an Aggie ring.
one ring per piston, the pistons have a groove in it where the ring fits on.
ring groove cleaner (if needed) and piston ring pliers (can just use your hand or needle nose)
As the piston moves up and down in the cylinder it also moves the piston rings up and down in the grooves. With the rings moving up and down it gradually increases the side clearence. Material is taken off from both the piston groove and the ring.
assuming that you have new cylinder liners and pistons or old pistons with good ring groove conditions, piston rings come with the correct/specified clearance when bought new.
There is a special tool for this purpose. Should be able to buy it or rent it at your local auto parts store.
Prevents wear on the pistin and reduces compression loss
The three main functions of piston rings in reciprocating engines are:Sealing the combustion/expansion chamber.Supporting heat transfer from the piston to the cylinder wall.Regulating engine oil consumption.
To prevent oil getting by the oil ring and compression past the others. Also, if they were in line, it would tend to make a groove in the cylinder wall.
You have to disassemble the entire engine, remove the piston and check the rubber ring around that piston.
The DNJ ring spec. information, printed on each compression ring (located next to the piston ring gap), is installed facing the top of the piston for both the top (#1) and middle (#2) compression piston ring slots. The oil control ring can be installed just like any other oil control ring in the bottom (#3) piston ring slot.
The only way to "check" a piston would be to remove it and visually inspect for damage and wear.Make certain that the piston is not cracked or otherwise damaged.check the ring grooves. Use a piston ring and a set of feeler gauges to determine the amount of wear. Excessive ring groove wear can result in piston failure and if the piston shatters, it can cause the engine to fail completely.Next, use a micrometer to determine the difference in the diameter of the piston between the top and bottom. The piston will wear and if the difference between the top and bottom is too great, the engine will exhibit "piston slap".Check the fit of the wrist pin, it should be tight.HOWEVERYou can run a compression test and get a good idea whether the piston is functioning somewhat correctly.
a piston ring is not calibrated. You just slide the new one in place
