WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
- Install rings on the pistons using a suitable ring expander. See Fig 1.
- Top compression ring is tapered and chromium plated. The second ring is of the scraper type and must be installed with scraping edge facing bottom of the piston. The third is an oil control ring. Ring gaps must be positioned, before inserting piston into the liners, as follows.
- Top ring gap must be positioned at the #3 position (looking at the piston crown from above). See Fig 2.
- Second piston ring gap should be positioned at the #1 position. See Fig 2.
- Oil control ring gap should be positioned at the #2 position. See Fig 2.
1 - SECOND COMPRESSION RING GAP POSITION 2 - OIL CONTROL RING GAP POSITION 3 - TOP COMPRESSION RING GAP POSITION - When assembling pistons check that components are installed in the same position as before disassembly, determined by the numbers stamped on the crown of individual pistons. Engine cylinders are numbered starting from gear train end of the engine. Face arrow on top of piston toward front of engine . Therefore, the numbers stamped on connecting rod big end should face toward the injection pump side of engine. To insert piston into cylinder use a ring compressor as shown in Figure.
