Enginetech are a good stock replacement type piston,they are just a rebox company so the piston is actually someone elses piston,we use them all the time at the machine shop i work at and never have any issues with them,from their cast pistons to their hyper pistons they are always good without any issues and i couldnt …

Are Enginetech parts any good?

“We buy a large portion of engine rebuild parts from Enginetech and are very satisfied with the quality of the parts and the fast and friendly service.”

Are Enginetech piston rings pre gapped?

ET piston rings come pre-gapped, however, it is always best practice to check your end gap before installation. We recommend a minimum of . 0035” per inch of cylinder diameter. Be sure to check your end gap at the bottom of the cylinder, below the ring travel area.

Which piston ring wears the most?

Thus, the highest wear rate in the piston ring and cylinder liner contact usually occurs at the TDC position during the power stroke. Wear can also occur at the bottom dead centre, but usually to a lesser extent, or the mid-stroke region, when abrasive particles are present.

Do piston rings make a difference?

We improve power by reducing internal friction in multiple cylinders. It can also be safely said thinner piston rings seal better, which means blow-by past the rings (lost power) is reduced. This means more cylinder pressure (heat energy) is captured above the pistons, rewarding us with greater sums of power.

Are Dnj valves good?

I actually use DNJ parts and I have never had an issue. Their quality is very good. Plus they are way cheaper in comparison to brands. At first I was mixed about using their parts.

Where are ITM engine components made?

ITM is not a manufacturer but a distributor. They buy parts from many of the same suppliers that supply OEMs and also the replacement market. Most of their sources are based in China but they also get some from Japan, Taiwan, and other places.

Do piston rings rotate in cylinder?

Yep,they do rotate. Crosshatch is also important because the amount, depth and angle of the crosshatch in the cylinder bores determines how much lubrication the rings receive and the rate of ring rotation.

How do you put rings on a piston?

Put one end of the ring in the grove and walk it around the piston until the end is in the ring grove. The rings must be placed in the proper direction otherwise the piston will not fit in the cylinder. It is extremely important that, when the piston is fed into the cylinder, each ring in place should be so positioned as to hug the locating pin.

How do you size a piston ring?

Gauge the gaps of piston rings with a new or old ring in place using a feeler gauge to measure the distance in between the ring gap and the ring when seated against the other gap wall. Determine the size of the space behind the ring, between the ring groove base and the back of the piston ring.

What size are piston rings?

LOW FRICTION PISTON RINGS. Over the years, rings have been getting smaller and thinner. Typical ring sizes today are 1.2 mm for the top compression ring, 1.5 mm for the second ring, and 3.0 mm for the oil ring.
