Crankshaft & Main Bearings
NOTE:
Crankshaft journals are fillet-rolled and cannot be re-ground to undersized dimensions.
- On 1.8L engines, mark main bearing cap location before removal. On all engines, measure main bearing oil clearance using Plastigage. Measure main bearing journal diameters. Measure journal taper and out-of-round. Measure crankshaft end play. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS and CONNECTING RODS tables under ENGINE SPECIFICATIONS.
- If oil clearance is not within specification, install a NEW bearing set and measure oil clearance again. Undersize bearings are available. If proper oil clearance cannot be obtained by using NEW bearings, replace crankshaft.
- On 1.5L engines, install main bearing caps in numerical order, according to number stamped on cap. Install bearing caps so arrow on top of cap points toward timing belt end of engine. On 1.8L engines, install main bearing caps in their original location, and with arrow on top of cap pointing toward timing belt end of engine. Tighten main bearing caps to specification in 2 stages, starting at center and working outward. See TORQUE SPECIFICATIONS .
- On 1.5L engines, when replacing main bearings, crankshaft and/or cylinder block, select NEW main bearings according to color codes on crankshaft and cylinder block. Select NEW main bearings using color codes from crankshaft and cylinder block. See Fig 1.
- On 1.8L engines, when replacing main bearings, crankshaft and/or cylinder block, select NEW main bearings according to color codes on crankshaft and cylinder block. Select NEW main bearings using color codes from crankshaft and cylinder block. See Fig 2.
