REMOVAL & INSTALLATION CRV



On the CRV, the rockers pivot on individual pedestals and do not use rocker shafts. The rockers are located underneath the camshafts, therefore the camshafts must be removed to access the rockers.

  1. Note the radio security code and station presets.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Remove the cylinder head valve cover.
  6.  
  7. Rotate the crankshaft in direction of operation until both camshaft sprockets have the UP at the top, and the Top Dead Center (TDC) marks on the camshaft sprocket and crankshaft are aligned with the pointers.
  8.  
  9. Remove the camshaft timing belt. Refer to the timing belt procedure located in this section.
  10.  
  11. Mark the distributor location for reinstallation and remove the distributor.
  12.  
  13. Loosen the valve adjustment locknuts and adjustment screws.
  14.  
  15. Carefully loosen the camshaft journal bolts about 1 / 2 a turn at a time until the bolts are loose.
  16.  

Be sure to note or mark the location of all parts prior to disassembly. All parts must be installed in the exact location from which they were removed.

  1. Remove the camshaft journals, camshaft, and rocker arms.
  2.

To install:
  1. Verify the engine is at TDC by the TDC marks on the crankshaft pulley and the pointer. If the engine is not at TDC, slowly and carefully rotate the crankshaft pulley to align the TDC timing marks.
  2.  
  3. Install the rockers onto the pivots, and lubricate with fresh engine oil.
  4.  
  5. Lubricate the camshaft journals and mounting bolts with fresh engine oil.
  6.  
  7. Place the camshafts in the cylinder head in the correct order, with the UP marks at the top and the TDC marks aligned with the TDC pointers.
  8.  
  9. Carefully clean and dry the cylinder head mating surfaces for the camshaft holders and apply a thin layer of a suitable sealant to the outer edges of the number one and number six cam journals on both the intake and exhaust camshaft holders. Refer to the shaded areas of the illustration provided.
  10.  
  11. Replace the cylinder head plug located at the end of the exhaust camshaft.
  12.  
  13. Install the camshaft journals and torque the camshaft journal bolts evenly to 86 inch lbs. (9.8 Nm) following the torque sequence provided in the illustration.
  14.  
  15. Install the timing belt, as outlined in this section.
  16.  
  17. Adjust the valves to the correct clearances.
  18.  
  19. Inspect the valve cover gaskets and replace if damaged. Apply a suitable non-hardening sealant to all eight of the corners on the gasket.
  20.  
  21. Install the cylinder head valve cover.
  22.  
  23. Locate the reference mark on the distributor, install the distributor and align the marks.
  24.  
  25. Reconnect the battery ground cable.
  26.  
  27. Start the engine and check for fluid leaks.
  28.  
  29. Top off all fluid levels as necessary.
  30.  
  31. Check the ignition timing and reset if necessary, For specific details see General Information and Maintenance .
  32.  
  33. Enter the radio security code.
  34.  

Odyssey

4-CYLINDER ENGINES
  1. Note the radio security code and station presets.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Remove the valve cover and the upper timing belt cover.
  6.  
  7. Set the No. 1 cylinder to Top Dead Center (TDC) for the compression stroke. Verify that the TDC marks are correctly aligned. Once the engine is set in this position, it must not be disturbed.
  8.  
  9. Remove the distributor as an assembly.
  10.  
  11. Loosen the valve adjusting screws.
  12.  
  13. Cover the timing belt with a clean shop towel to protect it from engine oil. If the belt is contaminated with oil, it must be replaced.
  14.  
  15. Loosen, but DO NOT remove the camshaft holder bolts from their holes in the shaft assemblies. Unscrew the bolts two turns at a time in a crisscross pattern to prevent damaging the valves. camshaft, or rocker arm assembly.
  16.  

The rocker arms and shafts are an assembly; they must be removed from the engine as a unit. To prevent warpage, always follow the tightening sequence carefully when removing or installing the rocker shaft assembly.

  1. Remove the rocker arm and shaft assemblies. Do not remove the camshaft holder bolts from the camshaft holder. The bolts keep the camshaft bearing caps, springs, and rocker arms in place on the shafts.
  2.  
  3. If the rocker arms or shafts are to be replaced, identify the parts as they are removed from the shafts to ensure reinstallation in the original location.

To install:
  1. Verify that the engine is set to TDC/compression for the No. 1 cylinder. The camshaft keyway faces up when the engine is at TDC/compression.
  2.

  4.  
  5. If necessary, assemble the rocker arms, shafts, and camshaft bearing caps.
  6.  
  7. Apply sealant to the mating surfaces of the first and last camshaft bearing caps. Do not allow the sealant to cure before the rocker arm assembly is installed.
  8.  
  9. Set the rocker arm assembly in place and loosely install the bolts. Tighten each bolt two turns at a time in the proper sequence to ensure that the rockers do not bind on the valves. Tighten the 8mm rocker arm bolts to 16 ft. lbs. (22 Nm). Tighten the 6mm bolts to 104 inch lbs. (12 Nm).
  10.  
  11. Verify that the engine is at TDC/compression, and install the distributor.
