REMOVAL & INSTALLATION CRV



  1. Note the radio security code and station presets.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Drain the engine oil into a sealable container.
  6.  
  7. Raise and safely support the vehicle.
  8.  
  9. Set the engine to No. 1 cylinder Top Deader (TDC).
  10.  
  11. Remove the valve cover and the timing belt middle cover.
  12.  
  13. Remove the accessory drive belts.
  14.  
  15. Remove the crankshaft pulley and the lower timing cover.
  16.  
  17. Remove the timing belt and drive pulley.
  18.  
  19. Remove the oil pan and the oil screen. Discard the screen gasket. Replace the oil screen if it shows signs of blockage.
  20.  
  21. Remove the oil pump mounting bolts and remove the oil pump assembly. Remove the dowel pins from the engine and clean the oil pump mating surfaces of old gasket material, oil, and sludge. Discard the O-rings.
  22.  

To install:
  1. Install a new crankshaft seal into the oil pump housing using an appropriately-sized seal driver.
  2.  
  3. Install the two dowel pins and new O-ring to the cylinder block.
  4.  
  5. Be sure that the mating surfaces are clean and dry. Apply liquid gasket evenly, in a narrow bead centered on the mating surface. Once the sealant is applied, do not wait longer than 20 minutes to install the parts; the sealant will become ineffective. After final assembly, wait at least 30 minutes before adding oil to the engine to give the sealant time to set. To prevent leakage of oil, apply a suitable thread sealer to the inner threads of the bolt holes.
  6.  
  7. Apply engine oil to the lip of the oil pump seal.
  8.  
  9. Install the oil pump and oil screen, tightening the mounting bolts/nuts to 86 inch lbs. ( 9.8 Nm).
  10.  
  11. Install the oil pan.
  12.  
  13. The completion of installation is the reverse of the removal procedure.
  14.  
  15. Lower the vehicle.
  16.  
  17. Fill the engine with clean engine oil.
  18.  
  19. Connect the negative battery cable, then enter the radio security code.
  20.  

Odyssey

4-cylinder engines
  1. Note the radio security code and disconnect the negative battery cable.
  2.  
  3. Remove the timing belt, balancer belt and tensioners.
  4.  
  5. If equipped with a Top Dead Center (TDC) sensor mounted on the oil pump housing, unbolt the sensor assembly and move it out of the way.
  6.  
  7. Remove the timing belt drive sprocket from the crankshaft.
  8.  
  9. Insert a pin punch or holder tool into the maintenance hole in the front balancer shaft (located behind the balancer sprocket). Hold the shaft steady with the tool and remove the balancer sprocket. Ensure the tool or bolt used is strong enough to resist bending when torque is applied to the sprocket nut.
  10.  

Front refers to the side of the engine facing the vehicle's radiator. Rear refers to the side of the engine facing the vehicle's firewall.

  1. Align the rear timing balancer sprocket using a 6 x 100mm bolt, rod, or pin punch. Mark the bolt or rod at a point 2.9 in. (74mm) from its end.
  2.  
  3. Remove the 12mm sealing bolt from the maintenance hole on the right side of the block below the water pump. Insert the bolt/rod into the hole until the 2.9 in. (74mm) mark you made on it is aligned with the face of the hole. This bolt/rod will act as a pin to hold the shaft in place.
  4.  
  5. Remove the balancer gear case and the dowel pins. Discard the O-ring.
  6.  
  7. Unbolt and remove the balancer driven gear. Leave the holder tool in the maintenance hole.
  8.  
  9. Remove the oil pan and the oil screen. Discard the screen gasket. Replace the oil screen if it shows signs of blockage.
  10.  
  11. Remove the oil pump mounting bolts and remove the oil pump assembly. Remove the dowel pins from the engine and clean the oil pump mating surfaces of old gasket material, oil, and sludge. Discard the O-rings.
  12.  

To install:
  1. Install new crankshaft and balancer shaft seals into the oil pump housing using an appropriately-sized seal driver.
  2.  
  3. Install the two dowel pins and new O-rings to the cylinder block.
  4.  
  5. Be sure that the mating surfaces are clean and dry. Apply liquid gasket evenly in a narrow bead, centered on the mating surface. Once the sealant is applied, do not wait longer than 20 minutes to install the parts; the sealant will become ineffective. After final assembly, wait at least 30 minutes before adding oil to the engine to give the sealant time to set. To prevent leakage of oil, apply a suitable thread sealer to the inner threads of the bolt holes.
