Honda CRV/Odyssey 1995-2000 Repair Information

Camshaft

Print

The camshafts on the CRV and Odyssey models are installed in the cylinder head and rotates in journals with journal caps that have been machined into the head. No bearings are used between the camshaft and the cylinder head. If a camshaft journal in the cylinder head has been damaged, the head must be replaced, and the cause of the journal failure should be determined before replacing the damaged components.


WARNING
Failure to install the camshaft journals in the exact location in which they belong, may cause severe damage to the cylinder head and camshaft.

REMOVAL & INSTALLATION CRV



  1. Note the radio security code and station presets.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Label and disconnect the spark plug wires.
  6.  
  7. Remove the valve cover and timing belt, as outlined in the procedures in this section.
  8.  
  9. Loosen the rocker arm locknuts and adjusting screws.
  10.  
  11. Remove the camshaft bearing caps, then carefully remove the camshafts.
  12.  
  13. Remove the rocker arms, noting their positions, and inspect for wear.
  14.  

To install:

Use new O-rings, seals, and gaskets when installing the camshaft.

  1. Clean and inspect the camshaft bearing caps in the cylinder head.
  2.  
  3. Lubricate the lobes and journals of the camshaft prior to installation. Install the camshaft and the bearing caps.
  4.  
  5. Tighten the camshaft bearing caps to 86 inch lbs. (9.8 Nm), in sequence.
  6.

  1. Set the camshafts at Top Dead Center (TDC) for No. 1 piston, align the holes in the camshafts with the holes in the No. 1 camshaft holder and insert a 5mm pin punch into the holes.
  2.  
  3. Install the keys into the keyways on the camshafts and install the pulleys, then tighten the retaining bolts to 27 ft. lbs. (37 Nm).
  4.  
  5. Install the timing belt. as outlined in this section.
  6.  
  7. Adjust the valve clearance.
  8.  
  9. Install the valve cover and tighten the nuts to 86 inch lbs. (9.8 Nm).
  10.  
  11. Connect the spark plug wires.
  12.  
  13. Connect the negative battery cable.
  14.  
  15. Enter the security code for the radio.
  16.  

Odyssey

4-CYLINDER ENGINES
  1. Note the security code for the radio.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. remove the timing belt, as outlined in this section.
  6.  
  7. Remove the rocker arm and shaft assembly. Leave the camshaft bearing cap bolts in the camshaft holders to hold the rocker arm/shaft assembly together.
  8.

  1. Remove the camshaft and camshaft seal.
  2.  

To install:

Use new O-rings, seals, and gaskets when installing the camshaft.

  1. Clean and inspect the camshaft bearing caps in the cylinder head.
  2.  
  3. Lubricate the lobes and journals of the camshaft prior to installation. Install the camshaft with the keyway facing up so that the engine remains at TDC/compression for the No. 1 piston.
  4.  
  5. Lubricate a new camshaft seal with engine oil. Use camshaft installer shaft 07NAF-PT0020A, installer cap 07NAF-PT0010A, and seal guide 07NAG-PT0010A, or their equivalents to install the camshaft seal.
  6.  
  7. Install the rocker shaft assembly.
  8.  
  9. Install the timing belt, as outlined in this section.
  10.  
  11. Connect the negative battery cable, then enter the security code for the radio.
  12.  

V6 ENGINE
  1. Note the security code for the radio.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. remove the following components, as outlined in this section:

    Timing belt
     
    Intake manifold
     
    Valve covers
     

  6.  
  7. Remove the rocker arm and shaft assembly. Leave the bolts in the rocker shaft to hold the rocker arm/shaft assembly together.
  8.  
  9. Remove the camshaft sprocket bolts and remove the sprockets.
  10.  
  11. Remove the camshaft thrust cover and the camshaft. Replace the oil seal if the oil seal lips are distorted.
  12.  

To install:

Use new O-rings, seals, and gaskets when installing the camshaft.

  1. Clean and inspect the camshaft bearing caps in the cylinder head.
  2.  
  3. Replace the camshaft oil seals and lubricate the lobes and journals of the camshafts prior to installation.
  4.  
  5. Install the camshafts.
  6.  
  7. Install the camshaft sprockets and torque the bolts to 67 ft. lbs. (90 Nm).
  8.  
  9. Install the rocker shaft assembly and torque the bolts to 17 ft. lbs. (24 Nm).
  10.  
  11. Install the valve covers, intake manifold and timing belt, as outlined in this section.
  12.

INSPECTION



Using solvent, degrease the camshaft and clean out all of the oil holes. Visually inspect the cam lobes and bearing journals for excessive wear. If a lobe is questionable, check all of the lobes as indicated. If a journal or lobe is worn, the camshaft MUST BE or replaced.

If a journal is worn, there is a good chance that the bearings or journals are worn and need replacement.

If the lobes and journals appear intact, place the front and rear journals in V-blocks and rest a dial indicator on the center journal. Rotate the camshaft to check the straightness. If deviation exceeds 0.001 in. (0.0254mm), replace the camshaft.

Fig. Fig. 5: Measuring camshaft straightness

Check the camshaft lobes with a micrometer, by measuring the lobes from the nose to the base and again at 90° (see illustration). The lobe lift is determined by subtracting the second measurement from the first. If all of the exhaust and intake lobes are not identical, the camshaft must be reground or replace.
