Inspection



  1. To check the lock of the camshaft timing gear, clamp the camshaft in a vice and confirm that the camshaft timing gear is locked.
    CAUTION
    Be careful not to damage the camshaft.

  2.  
  3. To release the lock pin, cover the four oil paths on the cam journal with vinyl tape. The two advance side paths are provided in the groove of the camshaft. Plug one of the paths with a piece of rubber.
  4.  
  5. Puncture the tape over the advance side path and retard the side path on the opposite side of the groove.
  6.  
  7. Apply air pressure to the two broken paths (the advance side path and the retard side path).
    WARNING
    Cover the paths with a shop rag to avoid oil splashes.

  8.  
  9. Confirm that the camshaft timing gear revolves in the timing advance direction when weakening the air pressure of the timing retard path.
  10.  
  11. When the camshaft timing gear comes to the most advanced position, release the air pressure of the timing retard side path, then release that of the timing advance side path.
  12.  
  13. There should be a smooth revolution of the gear.
  14.  

Cam Height

Use a micrometer to check camshaft (lobe) height, making sure the anvil and the spindle of the micrometer are positioned directly on the heel and tip of the camshaft lobe as shown in the accompanying illustration.

If the diameter is not as specified, check the oil clearance.

Camshaft & Followers

Inspect the camshaft(s) and followers as described earlier in this section.

Camshaft End Play

After the camshaft has been installed, end-play should be checked. The camshaft sprocket should not be installed on the cam. Use a dial gauge to check the end-play, by moving the camshaft forward and backward in the cylinder head. End-play specifications should be as noted in the Engine Mechanical Specifications chart.

Camshaft Gear Spring

Using a vernier caliper, measure the free distance between the spring ends.

5S-FE:



0.886-0.902 inch (22.5-22.9mm)
 

7A-FE:



0.669-0.693 inch (17.0-17.6mm)

If the free distance is not within specifications, replace the gear spring.

Camshaft Journal Clearance
  1. Clean the bearing caps and camshaft journals.
  2.  
  3. Place the camshafts on the cylinder head.
  4.  

Measure the bearing oil clearance by placing a piece of Plastigage® on each bearing journal. Replace the bearing caps and tighten the bolts to the proper torque.

Do NOT turn the camshaft.

Camshaft Runout

Camshaft runout should be checked when the camshaft has been removed from the engine. An accurate dial indicator is needed for this procedure; engine specialists and most machine shops have this equipment. If you have access to a dial indicator, or can take your camshaft to someone who does, measure the camshaft bearing journal runout. If the runout exceeds the limit replace the camshaft.

    6.  
    7. Alternately loosen and remove the bearing cap bolts on the No. 3 bearing cap. As these bolts are loosened check to see that the camshaft is being lifted out straight and level.
      NOTE
      If the camshaft is not lifted out straight and level, tighten the No. 3 bearing cap bolts. Reverse the order of Steps 7c through 7a and reset the intake camshaft knock pin to 10-45 degrees BTDC, then repeat Steps 7a through 7c. Do not attempt to pry the camshaft from its mounting.

    8.  
    9. Remove the No. 3 bearing cap and exhaust camshaft from the engine.
    10.  

  8.  
  9. Remove intake camshaft as follows:
    1. Set the knock pin of the intake camshaft at 80-115 degrees BTDC of the camshaft angle on the cylinder head. This angle will help to lift the intake camshaft level and evenly by pushing No. 1 and No. 3 cylinder camshaft lobes of the intake camshaft toward their valve lifters.
    2.  
    3. Remove the 2 front bearing cap bolts and remove the front bearing cap and oil seal. If the cap will not come apart easily, leave it in place without the bolts.
    4.  
    5. Uniformly loosen and remove the bearing cap bolts to No. 1, No. 3, and the No. 4 bearing caps in several phases and in the reverse order of the installation sequence. Do not remove bearing cap bolts to the No. 2 bearing cap at this time. Remove No. 1, 3, and 4 bearing caps.
    6.  
    7. Alternately loosen and remove bearing cap bolts to the No. 2 bearing cap. As these bolts are loosened and after breaking the adhesion on the front bearing cap, check to see that the camshaft is being lifted out straight and level.
      NOTE
      If the camshaft is not lifting out straight and level tighten the No. 2 bearing cap bolts. Reverse Steps 8b through 8d, then start over from Step 8b. Do not attempt to pry the camshaft from its mounting.

    8.  
    9. Remove the No. 2 bearing cap with the intake camshaft from the engine.
    10.  

  10.  
  11. Remove the valve lifter shims and hydraulic lifters. Identify each lifter and shim as it is removed so it can be reinstalled in the same position. If the lifters are to be reused, store them upside down in a sealed container.
  12.  

To install:

  1. Install the valve lifters into their original positions and shims.
    NOTE

    1. Set the knock pin of the intake camshaft at 80-115 degrees BTDC of the camshaft angle on the cylinder head. This angle will help to lift the intake camshaft level and evenly by pushing No. 1 and No. 3 cylinder camshaft lobes of the intake camshaft toward their valve lifters.
    2.  
    3. Remove the 2 front bearing cap bolts and remove the front bearing cap and oil seal. If the cap will not come apart easily, leave it in place without the bolts.
    4.  
    5. Uniformly loosen and remove the bearing cap bolts to No. 1, No. 3, and the No. 4 bearing caps in several phases and in the reverse order of the installation sequence. Do not remove bearing cap bolts to the No. 2 bearing cap at this time. Remove No. 1, 3, and 4 bearing caps.
    6.  
    7. Alternately loosen and remove bearing cap bolts to the No. 2 bearing cap. As these bolts are loosened and after breaking the adhesion on the front bearing cap, check to see that the camshaft is being lifted out straight and level.
      NOTE
      If the camshaft is not lifting out straight and level tighten the No. 2 bearing cap bolts. Reverse Steps 8b through 8d, then start over from Step 8b. Do not attempt to pry the camshaft from its mounting.

    8.  
    9. Remove the No. 2 bearing cap with the intake camshaft from the engine.
    10.  

  10.  
  11. Remove the valve lifter shims and hydraulic lifters. Identify each lifter and shim as it is removed so it can be reinstalled in the same position. If the lifters are to be reused, store them upside down in a sealed container.
  12.  

To install:

  1. Install the valve lifters into their original positions and shims.
    NOTE
    Before installing the intake camshaft, apply multi-purpose grease to the camshaft.

  2.  
  3. Install the intake camshaft, as follows:
    1. Position the camshaft at 80-115 degrees BTDC of camshaft angle on the cylinder head.
    2.  
    3. Apply sealant to the front bearing cap.
    4.  
    5. Coat the bearing cap bolts with clean engine oil.
    6.  
    7. Tighten the camshaft bearing caps evenly in sequence and in several passes to 14 ft. lbs. (19 Nm).
    8.  
    9. Apply MP grease to a new oil seal lip, and by using a suitable tool, tap a new oil seal into place.

    12.  
    13. Apply multipurpose grease to the camshaft.
    14.  
    15. Position the exhaust camshaft gear with the intake camshaft gear so that the timing marks are in alignment with one another. Be sure to use the proper alignment marks on the gears. Do not use the assembly reference marks.
    16.  
    17. Turn the intake camshaft clockwise or counterclockwise little by little until the exhaust camshaft sits in the bearing journals evenly without rocking the camshaft on the bearing journals.
    18.  
    19. Coat the bearing cap bolts with clean engine oil.
    20.  
    21. Tighten the camshaft bearing caps evenly in sequence and in several passes to 14 ft. lbs. (19 Nm). Remove the service bolt from the assembly.
