Camshaft, Bearings & Lifters Replacing on Honda Odyssey?

Camshaft, Bearings & Lifters removal and installation with details and diagrams.

First inspect then perform replacing.

Inspection


  1. Remove the cylinder head.
  2. Remove the rocker arm assembly.
  3. Put the rocker shafts on the cylinder head, then tighten the bolts to 17 ft. lbs. (24 Nm).
  4. Seat the camshaft by pushing it toward the rear of the cylinder head.
  5. Zero the dial indicator against the end of the camshaft. Push the camshaft back and forth and read the end play. If the end play is beyond the service limit, replace the thrust cover and recheck. If it is still beyond the service limit, replace the camshaft.
  6. Remove the camshaft thrust cover, then pull out the camshaft.
  7. Wipe the camshaft clean, then inspect the lift ramps. Replace the camshaft if any lobes are pitted, scored, or excessively worn.
  8. Measure the diameter of each camshaft journal.
  9. Zero the gauge to the journal diameter.
  10. Clean the camshaft bearing surfaces in the cylinder head. Measure the inside diameter of each camshaft bearing surface, and check for an out-of-round condition. If the camshaft-to-holder clearance is beyond the service limit and the camshaft has been replaced, replace the cylinder head.
  11. If the camshaft-to-holder clearance is beyond the service limit and the camshaft has not been replaced, check total runout with the camshaft supported on V-blocks. If the total runout of the camshaft is within the service limit, replace the cylinder head. If the total runout is beyond the service limit, replace the camshaft and recheck the oil clearance. If the oil clearance is still out of tolerance, replace the cylinder head.
  12. Measure cam lobe height.
