Piston & Rod Assembly: Removal

  1. With cylinder heads, oil pan, and oil pump removed, inspect cylinder bores for ridges and/or deposits. Move piston to be removed to bottom of bore and cover with cloth to catch cuttings.
  2. Remove ridge at top of cylinder bores (using ridge reamer) before removing pistons from block. Rotate crankshaft and inspect rods and caps for identification. Mark if necessary.
  3. Remove rod cap and push each piston and rod assembly out top of cylinder bore. To protect crankshaft, place Connecting Rod Bolt Guide Set (J-5239) or 3/8" rubber hose over rod bolts. Remove bearing inserts from rod and cap. Inspect for size, wear and damage. Install rod caps on mating rods.
NOTE: Notch on piston top faces front of engine. Pistons are numbered from front-to-rear with No. 2-4-6-8 on right bank and No. 1-3-5-7 on left bank.
