Question about 2001 Toyota Avalon

Remove the Camshaft timing gear (VVTI)

I am removing the intake Camshaft to test /replace the Camshaft timing gear. A service bolt is necessary for the Exhaust Gear to assure it does not move (as it is under tension). The Front intake cam went fine with service bolt on top and accessible. Rear Shaft is posing a problem since the service bolt location is on the bottom. Do I need to turn the shaft to access the bolt location and return the * to * timing markings after the bolt is installed? Is there a correct way to do this without damaging anything or am I missing something completely? Engine was placed at TDC prior to repair and *to* timing marks align on each Cam gear.

I am not sure how it can be out of time when the dots * to * line up exactly on both the front and rear cam. I just dont understand how one is supposed to get the service bolt in the rear cam since it is on the bottom of the exhaust gear.

SOURCE: 1998 4cyl.camry had a stuck valae due to bad

simple to figure that out . the key ways are always up on camshafts. it allows for them not to fall out when assembling the engine . so use the balancer to determine tdc (top dead center on cyl one) and make sure both keys are straight up . (just loosen the cam retainer nuts and look to see what set of marks they line up with and dont forget t re-torque them to factory specs somewhere between 22 and 28 ft lbs but not a lot more) , google the specs up to be sure

Check this procedure... REMOVALand& INSTALLATION

6-300
  1. Remove the grille, radiator, and timing cover.
  2. Remove the distributor, fuel pump, oil pan and oil pump.
  3. Align the timing marks. Unbolt the camshaft thrust plate, working through the holes in the camshaft gear.
  4. Loosen the rocker arms, remove the pushrods, take off the side cover and remove the valve lifters with a magnet.
  5. Remove the camshaft very carefully to prevent nicking the bearings.
  6. Oil the camshaft bearing journals and use Lubriplate or something similar on the lobes. Install the camshaft, gear, and thrust plate, aligning the gear marks. Tighten down the thrust plate. Make sure that the camshaft end-play is not excessive.
  7. The last item to be replaced is the distributor. The rotor should be at the firing position for no. 1 cylinder, with the timing gear marks aligned

V6 and V8 Including Diesel
Ford recommends removing the diesel engine for camshaft removal.
  1. Remove the intake manifold and valley pan, if so equipped.
  2. Remove the rocker covers, and either remove the rocker arm shafts or loosen the rockers on their pivots and remove the pushrods. The pushrods must be reinstalled in their original positions.
  3. Remove the valve lifters in sequence with a magnet. They must be replaced in their original positions.
  4. Remove the timing chain/gear cover and timing chain (timing gear on V8 diesel) and sprockets.
  5. In addition to the radiator and air conditioning condenser, if so equipped, it may be necessary to remove the front grille assembly and the hood lock assembly to gain the necessary clearance to slide the camshaft out of the front of the engine. On the V6-3.8L, remove the camshaft thrust button and spring. Remove the camshaft thrust plate attaching screws and carefully slide the camshaft out of its bearing bores. Use extra caution not to scratch the camshaft lobes.
Camshaft removal tools, Ford part no. T65L-6250-A and adaptor 14-0314 are needed to remove the diesel camshaft.
  1. Coat the camshaft with engine oil liberally before installing it. Slide the camshaft into the engine very carefully so as not to scratch the bearing bores with the camshaft lobes. Install the camshaft thrust plate and tighten the attaching screws to 9 - 12 ft. lbs. Measure the camshaft end-play. If the end-play is more than 0.009 inch; (0.228mm), replace the thrust plate. Assemble the remaining components in the reverse order of removal.

Need to remove cilinderhead from a chevrolet trailblazer 2003


below are the instruction you well need to remove head .....good luck Removal Procedure
  1. Remove the air cleaner element.
  2. Remove the air cleaner outlet resonator. .
  3. Remove the powertrain control module (PCM) and engine wire harness bracket and related hoses and connections.
  4. Remove the generator.
  5. Remove the intake manifold.
  6. Remove the exhaust manifold. Do not remove the exhaust pipe from the manifold. Only have the manifold pushed off to the side of the engine.
  7. Position the A/C line out of the way towards the front of the vehicle.
  8. Disconnect the following cross-vehicle engine wiring harness connectors:
  9. • Engine coolant temperature sensor • Manifold absolute pressure (MAP) sensor • Ignition coils • Harness clamps at power steering pump • Wiring harness fastener at the right front inner fender • Throttle body • Camshaft sensors • Camshaft actuators • Fuel rail • Heated oxygen sensor (HO2S)
  10. Set aside the cross-vehicle engine wiring harness on the left side of the vehicle.
  11. Remove the camshaft cover.
  12. Partially drain the cooling system.

  13. Before performing one of the top dead center (TDC) procedures, break loose both the exhaust and intake camshaft sprocket bolts. Use a 25 mm (1 in) open end wrench on the camshaft hexes to hold the camshaft from turning. DO NOT remove the bolts.
  14. Perform one of the following methods for the service timing procedure.
  15. First Method--Rotate the engine clockwise by hand to TDC on the compression stroke by using a piston TDC indicator tool and/or dial indicator in the number 1 cylinder.
  16. First Method (continued)--The TDC indicator tool graduation marks on the shaft should note top of the piston stroke.
  17. First Method (continued)--When the piston is at TDC, the flats at the rear of the camshafts will be facing up and level when using a straight edge across the camshaft flats.
  18. Second Method--Rotate the crankshaft in the engine rotational direction clockwise until the number 1 piston is at TDC on the compression stroke. The word Delphi on the exhaust camshaft position actuator will be parallel with the cylinder head to cam cover mating surface. When the piston is at TDC, the flats at the rear of the camshafts will be facing up and level when using a straight edge across the camshaft flats. A 0.005 inch feeler gauge should not slide under the straight edge (1).
  19. Use a white paint pen or equivalent to place a reference mark on the harmonic balancer to the front cover for alignment purposes.
  20. Lower the vehicle.
  21. Important: If the timing is correct (TDC compression stroke number 1 cylinder), the camshaft flats will be in the up position.
    Install J 44221 to the back of the camshafts.
  22. Remove the upper timing chain guide to the cylinder head.
  23. Clean the timing chain and gears with brake cleaner or suitable solvent. Use a white paint pen or equivalent to place a reference mark on both timing gear sprockets and the timing chain to mark location prior to disassembly. It is recommended that the paint marks be in the 12 o'clock position.

  24. Install EN-48464 . It is important to install the tool with the proper orientation and to ensure that it is seated square against the timing chain and against the timing cover center bolt.


  25. The narrow ramp of the wedge tool needs to be placed so that it faces the timing chain.
  26. The wedge tool should be lightly seated using a couple of very light taps with a small plastic or brass hammer. The wedge tool will be fully seated against the tensioner after it moves about 25 mm (1 in).
  27. Once the tool is correctly installed, unscrew the handle and remove the handle

  28. Remove both upper cylinder head access hole plugs from the front of the cylinder head.
  29. Remove the 1 long and 2 short cylinder head bolts next to the exhaust and intake timing chain tensioner shoes and discard the bolts.
  30. Remove both upper timing chain tensioner shoe bolts.
  31. Remove the exhaust and the intake camshaft sprocket bolts. Discard the bolts.


  32. Carefully remove the exhaust and intake camshaft sprockets with the timing chain from the exhaust and intake camshafts. The illustration shows the exhaust camshaft sprocket already removed.


  33. Remove the sprockets from the chain, tie a piece of mechanic's wire on the timing chain and let it drop.


  34. Before removing the cylinder head bolts, use a drift punch and hammer to shock the bolts. This will ensure that the cylinder head bolts will not strip out the threads in the engine block or break. If a bolt breaks during engine disassembly, EN-47702 is available to assist in the removal of the remaining bolt segment.
  35. Remove the cylinder head bolts. Discard the bolts.
  36. Remove the cylinder head.
  37. Place the cylinder head on a flat, clean surface with the combustion chambers face up, in order to prevent damage to the deck face.
  38. Remove the cylinder head gasket.
  39. Discard the gasket.
  40. Remove all remaining gasket material from the engine block.
  41. Inspect the cylinder head gasket mating surface on the engine block.
  42. Clean and inspect the cylinder head.
  43. Disassemble the cylinder head if necessary.

How do i reset the timing in a 1997 z24 Chevrolet Cavalier 2.4 twin cam? Where are the timing marks on the cam gears?


2.3L and 2.4L Engines Before attempting to remove the timing chain, read the entire procedure.
  1. Disconnect the negative battery cable.
  2. Remove the timing chain front cover, as outlined earlier in this section.
  3. Rotate the crankshaft clockwise, as viewed from the front of engine/normal rotation, until the camshaft sprocket timing dowel pin holes line up with the holes in the timing chain housing. The crankshaft sprocket keyway should point upwards and line up with the centerline of the cylinder bores. This is the "timed'' position. Fig. 8: The chain must be in the "timed'' position - 2.3L and 2.4L engines 87953108.gif
    Fig. 9: Remove the timing chain guides 87953109.gif

  4. Remove the timing chain guides.
  5. Raise and safely support the vehicle.
  6. Make sure all of the slack in the timing chain is above the tensioner assembly, then remove the tensioner. The timing chain must be disengaged from any wear grooves in the tensioner shoe in order to remove the shoe. Slide a suitable prytool under the timing chain while pulling the shoe outward. WARNING
    Do NOT attempt to pry the socket off the camshaft or damage to the sprocket or chain housing could occur.
  7. If difficulty is encountered in removing the chain tensioner shoe, remove the intake camshaft sprocket, as follows;
    1. Carefully lower the vehicle.
    2. Hold the intake camshaft sprocket with a suitable tool and remove the sprocket bolt and washer.
    3. Remove the washer from the bolt and rethread the bolt back into the camshaft by hand. The bolt provides a surface to push against.
    4. Remove the camshaft sprocket using a three-jaw puller in the three relief holes in the sprocket.
  8. Unfasten the tensioner assembly retaining bolts, then remove the tensioner. NOTE: The timing chain and crankshaft sprocket MUST be marked before removal. If the chain or sprocket is installed with the wear pattern in the opposite direction, noise and increased wear may occur.
  9. Mark the crankshaft sprocket and timing chain outer surface for reassembly, then remove the chain.
  10. Clean the old sealant off the bolt with a wire brush. Clean the threaded hole in the camshaft with a round nylon brush. Inspect the parts for wear and replace as necessary. Note that some scoring of the chain shoe and guides is normal. To install: WARNING
    Failure to follow this procedure may result in severe engine damage.
  11. Position the intake camshaft sprocket onto the camshaft with the surface marked during removal showing.
  12. Install the intake camshaft sprocket retaining bolt and washer, tighten to 52 ft. lbs. (70 Nm) while holding the sprocket with a suitable tool. Use GM sealant 12345493 or equivalent on the camshaft sprocket bolt.
  13. Place GM tool J 36008, or equivalent camshaft aligning pins, through the holes in the camshaft sprockets into the holes in the timing chain housing. This positions the cams for correct timing.
  14. If the camshafts are out of position and must be rotated more than 1?8 turn in order to install the alignment dowel pins, proceed as follows:
    1. The crankshaft MUST be rotate 90°clockwise off of TDC in order to five the valves adequate clearance to open.
    2. Once the camshafts are in position and the dowels installed, rotate the crankshaft counter clockwise back to TDC. WARNING
      Do not rotate the crankshaft clockwise to TDC; valve or piston damage could result. NOTE: The side of the timing chain that was marked during removal must be showing when the chain is installed.

  15. Place the timing chain over the exhaust camshaft sprockets, around the idler sprocket and around the camshaft sprocket.
  16. Set the camshafts at the timed position and install the timing chain. Remove the alignment dowel pin from the intake camshaft. Using GM tool J 39579, rotate the intake camshaft sprocket counter clockwise enough to slide the timing chain over the intake camshaft sprocket. Release the camshaft sprocket wrench (J 39579 or equivalent). The length of the chain between the two camshaft sprockets will tighten. If properly timed, the intake camshaft alignment dowel pin should slide in easily. If the dowel pin does not fully index, the camshafts are NOT timed correctly and the procedure must be repeated.
  17. Leave the alignment dowel pins installed. Raise and safely support the vehicle.
  18. With the slack removed from the chain between the intake camshaft sprocket and the crankshaft sprocket, the timing marks on the crankshaft and cylinder block should be aligned. If the marks are not aligned, move the chain one tooth forward or rearward, remove the slack and recheck the marks. Fig. 10: Timing chain assembly retaining bolts - 2.3L and 2.4L engines 87953111.gif

  19. Reload the timing chain tensioner assembly to its "zero'' position as follows:
    1. Form a keeper from a piece of heavy gauge wire, as shown in the accompanying figure.
    2. Apply slight force on the tensioner blade to compress the plunger.
    3. Insert a small prytool into the reset access hole, and pry the ratchet pawl away from the ratchet teeth while forcing the plunger completely in the hole.
    4. Install the keeper between the access hole and the blade. Fig. 11: Reloading the tensioner to its "ZERO'' position, then install to the chain housing 87953110.gif

  20. Install the tensioner assembly to the timing chain housing. Recheck the plunger assembly installation, it is correctly installed when the long end is toward the crankshaft. Install the tensioner retaining bolts; tighten to 89 inch lbs. (10 Nm).
  21. Carefully lower the vehicle enough to reach and remove the alignment dowel pins. WARNING
    Severe engine damage could result if the engine is not properly timed.
  22. Rotate the crankshaft clockwise (normal rotation) two full rotations. Align the crankshaft keyway with the mark on the cylinder block and reinstall the alignment dowel pins. The pins will slide in easily if the engine is correctly timed.
  23. Install the timing chain guides, then install the front (timing chain) cover.
  24. Connect the negative battery cable.

How to change a timming belt on honda civic


Timing Belt and Tensioner REMOVAL & INSTALLATION 1984–87 Engines
  1. Turn the crankshaft pulley until it is at Top Dead Center.
  2. Remove the pulley belt, water pump pulley, crankshaft pulley, and timing gear cover. Mark the direction of timing belt rotation.
  3. Loosen, but do not remove, the tensioner adjusting bolt and pivot bolt.
  4. Slide the timing belt off of the camshaft timing gear and the crankshaft pulley gear and remove it from the engine.
  5. To remove the camshaft timing gear pulley, first remove the center bolt and then remove the pulley with a pulley remover or a brass hammer. This can be accomplished by simply removing the timing belt upper cover, loosening the tensioner bolts, and sliding the timing belt off of the gear to expose the gear for removal. NOTE: If you remove the timing gear with the timing belt cover in place, be sure not to let the woodruff key fall inside the timing cover when removing the gear from the camshaft. Inspect the timing belt. Replace if over 90,000 miles old, if oil soaked (find source of oil leak also), or if worn on leading edges of belt teeth. Fig. 1: Timing belt and front cover assembly — 1984–87 engines 86833161.gif
    Fig. 2: Positioning the crankshaft and camshaft pulleys before installing the timing belt — 1984–87 engines 86833162.gif
    Fig. 3: Timing belt tension adjustment — 1984–87 engines 86833163.gif
    To install:
  6. Be sure to install the crankshaft pulley and the camshaft timing gear pulley in the top dead center position. Align the marks on the camshaft timing gear so they are parallel with the top of the cylinder head and the woodruff key is facing up. NOTE: When installing the timing belt, do not allow oil to come in contact with the belt. Oil will cause the rubber to swell. Be careful not to twist the belt unnecessarily or bend in a 90°angle, since it is made with fiberglass; nor should you use tools having sharp edges when installing or removing the belt. Be sure to install the belt with the arrow facing in the same direction it was facing during removal.
  7. After installing the belt, adjust the belt tension by first rotating the crankshaft counterclockwise 1/4 turn. Then, re-tighten the adjusting bolt and finally the tensioner pivot bolt.
  8. Replace the other components removed for belt access.
  9. Start the car, check timing and adjust if necessary WARNING
    Do not remove the adjusting or pivot bolts, only loosen them. When adjusting, do not use any force other than the adjuster spring. If the belt is too tight, it will result in a shortened belt life.
