21.06.2006: Rings ready
The first compression ring is a solid metal ring. The second is a scraper type and might come with an expander ring (Saab OEM kits don't have expander rings). The third ring is a multi-piece oil scraper, which has two thin rails with a spacer between them, as well as an optional expander. Have some oil ready to lubricate the rings before installation.

Piston and crankshaft installation on a Saab B204/B234 engine. This engine is found in all four-cylinder Saab 900 and 9000 from 1994 to 1998, as well as 1999 9-3. Newer cars have lighter pistons and a slightly different block but the procedure is still the same.

Tools and supplies:

  • Torx E16 socket: main crankshaft cap bolts;
  • 12-point 14 mm socket: connecting rod cap nuts;
  • 6-point 14 mm socket: oil jets;
  • torque wrench;
  • piston ring compressor;
  • piston ring expander;
  • fresh engine oil.
