  1. ENGINE REASSEMBLY RK • Chapter 12 • Classroom Manual page 311 • Lab Manual page 325

  2. OBJECTIVES RK • Properly install cam bearings , and cam. • Correctly install main bearings & check clearance. • Properly install crank & check end play. • Correctly install the piston assemblies into the block & check rod bearing clearance. • Prime oil pump. • Properly complete short block .

  3. INTRODUCTION RK • IT IS NOT POSSIBLE TO BE TOO CLEAN! • This is the last chance to find defects. • Make all measurements. • Torque all components. • Keep engine covered at all times.

  4. ENGINE BLOCK PREP RK • Chamfer all bolt holes, clean all threads. • Check chamfer on cylinder bores. • Measure deck surfaces. • Inspect sealing surfaces. • Inspect all bearing surfaces . • Check the inspection checklist. • Install all bushings. • Install soft plugs.

  5. INSTALLING CAM BRGS RK • Determine proper bearing position. • Ensure the bearing does not drive in to “hard” or to “easy”. • ALIGN OIL HOLE IN BEARING AND BLOCK. Page 312 C & 326 L

  6. INSTALLING THE CAM RK • Use special cam lube. • Do not nick bearings when installing cam. • Cam must turn by hand. • Install thrust plate. Page 313 C & 327 L

  7. INSTALLING CRANK RK • Replace pilot bearing. 328 L • Clean crank oil passages with a brush. 314 C • Install upper main bearing halves. 314 C • Use engine assembly lube. • Plasti-gauge main bearing clearance. 332 L • Check crank end play. 333 L

  8. INSTALLING PISTONS RK • Measure piston to wall clearance. 319 C • Make sure crank pin is at BDC. 319 C • Use engine assembly lube on rod bearings. • Use ONLY engine oil on pistons. • Protect crank from rod bolts with rubber hose. • Plasti-gauge all rod bearings.

  9. INSTALLING PISTONS RK • Check piston rings are installed correctly. • Ensure ring gaps are staggered. • Check rod side clearance.

  10. DECK CLEARANCE RK • Check deck height.

  11. INSTALLING OIL PUMP RK • Install pickup screen. • Prime the oil pump. This is NOT priming the engine. • Gasket or no gasket. • Install intermediate shaft.

  12. CAM TIMING - DEGREEING RK • Only with performance type camshafts.
