Normal quality for untrimmed and moderately tuned engines, if you're aiming for 100 km / h try SKF bearings instead. Contains 2 L17 for the crankshaft and 2 support bearings 6202 C3. Picture 2 shows the supportbearings, remember the retaining rings. If you tap the bearings in place, always tap on the outer ring, not in the inner one. If you have a four-speed engine, you have to dismount the leftmost support bearing when combining the engine halves, it's mounted later. When mounting the L17 bearing in the block, you can heat the block in the oven at 100 degrees and put the bearing rings in the freezer.Then it is very easy to get them in place.
