Default Re: How to mount the piston rings from above?

Guten Tag.

The new rings arrived yesterday. Hastings look different than the previously assembled ones.

The second pressure ring had a lower nose on the outside for additional wiping off of the oil. This is not the case with the new ones, they have only a chamfer at the bottom and inside.

In addition, this wafer-thin steel shaft was under the ring. The Hastings didn't have this corrugated ring, so I didn't reassemble the old ones.

The scraper rings are also designed differently. At least not so fragile. The assembly of the oil control rings was very difficult with a lot of time over two hours.
