Engine Reassembly Procedures
Follow the procedures listed below in reassembling the
engine.
1. Install the camshaft bushing.
2. Install the main bearings to the cylinder block and
main bearing cap. Ensure that these are in proper
position.
3. Install the crankshaft.
4. Install the main bearing caps then tighten the cap
bolts to the specified torque. Each cap carries an em-
bossed arrow mark and letter or numeral to indicate its
position in the cylinder block. When installing the no. 1
and no. 4 bearing caps, apply sealant to the upper
surface (that meets with the cylinder block).
5. With the bolts torqued use a dial indicator on the end
of the crankshaft to measure the crankshaft end play. If
the end play exceeds .0197 inch (0.5 mm) replace the
No. 3 main bearing.
