This would be normal for an engine with compression. If it does this with a starter, then the compression may be too much for the starter.

Also if the timing were overadvanced, it would bind against the compression.

SOURCE: cant get the crankshaft pulley off

It's most likely right hand thread. You will have to use a large breaker bar to get enought leverage to remove this nut. Or you can use what ever you have and place a steel pipe on the end of it for extra leverage. If it doesn't budge, you may have to soak it in penetrating oil, and use an impact wrench. Make sure you remove the large washer under the nut "before" you remove pulley.

SOURCE: can't remove crankshaft timing belt pulley BOLT!

You will have to brace the crankshaft somehow, either by way of the flywheel, or the pulley. The trick to getting the bolt to break is "heat". Propane will sometimes work, but it's generally not hot enough. You want to get that bolt glowing if you can, and hit it with air impact then. Be careful not to burn yourself!

I hope this helps you, and I wish you luck on your repair.

SOURCE: screech in engine. after serpentine belt stops

Check if screeching is related to engine vacuum.
Briefly remove (or loosen off) the oil filler cap - if noise immediately stops high crankcase vacuum is the cause. Check / replace PCV valve to fix.
If above is not the cause, listen with a short length of hosepipe to try and narrow down noise source.
Silicon lube spray or pencil lead graphite on a selected belt should cause sound change if it's caused by that belt.

Crankshaft pulley is hard to turn by hand


Yes that is normal, the pistons come up and the pressure in the cylinder causes resistance. Go online and read how a 4 stroke gas or diesel engine works

Timing a wl mazda diesel engine


remove #1 spark plug.

  1. Rotate the engine so that No. 1 cylinder is at Top Dead Center (TDC) on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to be sure that the timing mark on the cam drive sprocket is aligned with the pointer on the inner belt cover.
    NOTE

    Always turn the engine in the normal direction of rotation. Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner.

  2. Drain cooling system. Remove the upper radiator hose as necessary. Remove the fan blade and water pump pulley bolts.
    CAUTION

    When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  3. Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.

  4. Remove the power steering pump and set it aside.

  5. Remove the 4 timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.

  6. Loosen the belt tensioner pulley assembly, then position a Camshaft Belt Adjuster tool T74P-6254-A, or equivalent, on the tension spring roll pin and retract the belt tensioner away from the timing belt. Tighten the adjustment bolt to lock the tensioner in the retracted position.

  7. If the belt is to be reused, mark the direction of rotation on the belt for installation reference.

  8. Remove the timing belt.

    Camshaft, auxiliary shaft and crankshaft timing belt sprocket alignment mark locations-Mazda B-Series Pick-Ups 2.5L (VIN C) engines

To install:

  1. Install the new belt over the crankshaft sprocket and then counterclockwise over the auxiliary and camshaft sprockets, making sure the lugs on the belt properly engage the sprocket teeth on the pulleys. Be careful not to rotate the pulleys when installing the belt.

  2. Release the timing belt tensioner pulley, allowing the tensioner to take up the belt slack. If the spring does not have enough tension to move the roller against the belt (belt hangs loose), it might be necessary to manually push the roller against the belt and tighten the bolt.
    NOTE

    The spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly.
    WARNING

    If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.

  3. Rotate the crankshaft 2 complete turns by hand (in the normal direction of rotation) to remove slack from the belt. Tighten the tensioner adjustment to 26-33 ft. lbs. (35-45 Nm) and pivot bolts to 30-40 ft. lbs. (40-55 Nm). Be sure the belt is seated properly on the pulleys and that the timing marks are still in alignment when No. 1 cylinder is again at TDC/compression.

  4. Install the crankshaft pulley and belt guide.

  5. Install the timing belt cover.

  6. Install the water pump pulley and fan blades. Install the upper radiator hose if necessary. Refill the cooling system.

  7. Install the accessory drive belts.

  8. Start the engine and check the ignition timing. Adjust the timing, if necessary.

Loud roar sound coming from the fan or something and broke new belt


Hi James, I suspect a damaged bearing.. Before fitting the new belt rotate all idlers and pulley's by hand to determine which one is defective.. The cam shaft and crankshaft pulleys should be inspected for damage but don't worry about hand rotating them. Find out which of the others (water pump, power steering pump, AC, and all idlers have a problem. (That or those which do not rotate smoothly will be your suspects and need replacement. Regards John

Need to undo front pulley on lanos 1998 1.5 ltr. Is it left hand thred or normal anti clockwise to undo? and how to stop motor from turning? (on front of crankshaft)


Here is a way to rmove the crankshaft pulley screw. Its fa previous solution of mine. But it will work for you. And this is how I always do it.

Get a breaker bar, 18 inch or longer, put on a socket that fits the crank pulley screw. Note the direction the crankshaft rotates when the car is running. Position the breaker bar so that when you turn the key the breaker bar will hit the ground and cause the screw to be loosened.

Ideally the socket will be on the screw and the breaker bar will be touching the ground. Turn the ignition long enough for the starter to turn the engine, and immediately turn the key off. Turn it for a half second and back off. Just long enough for the starter to engage for a split-second.

(1999 pontiac grand prix 3100 v6) how do I remove and replace my serpentine belt successfully?


Instructions Things You'll Need
  • 3/8-inch drive breaker bar
  • Metric socket kit
  • New serpentine belt
    • 1

      Park the Pontiac in a safe work area and open the hood.

    • 2

      Inspect the top of the black plastic cover that surrounds the fan for the serpentine belt routing diagram. This diagram has the instructions for installing the new serpentine belt around the accessory pulleys.

    • 3

      Inspect the front of the engine and locate the automatic belt tensioner. The tensioner on the 1999 Pontiac model vehicles is located between the alternator and the crankshaft pulley. The tensioner has a pulley on one end with a bolt head in the center of the pulley. Use the bolt head to rotate the tensioner.

    • 4

      Turn the tensioner counterclockwise with the breaker bar and a metric socket. Pull the belt out from under the tensioner pulley with your other hand. Then, slowly let the tensioner retract until it stops.

    • 5

      Pull the belt out of the other remaining pulleys. Then, pull the belt out of the engine bay and lay it on the ground.

    • 6

      Route the new belt around the crankshaft pulley. Then, route the new belt around the other remaining pullleys by using the serpentine belt routing diagram for instructions.

    • 7

      Rotate the tensioner pulley counterclockwise with the breaker bar and socket. Then, slide the new belt under the tensioner pulley. Slowly let the tensioner retract until it stops. The tensioner pulls all of the slack out of the belt and brings the new belt to the proper tension. Remove the breaker bar and socket from the tensioner pulley.

    • 8

      Inspect the new belt to ensure that it is seated inside of all the accessory pulleys as directed by the diagram. Then, crank the engine and allow it to run for about 15 seconds. Turn the engine off. Inspect the belt again once more to ensure that
      the belt is still around each pulley. Close the hood.

Is the crankshaft pulley bolt left or right thread to undo diesel P38 engine


the bolt will turn opposite direction of your engines rotation. so if when setting the timing your manual tells you to crank your engine clockwise then you will need to rotate the bolt clockwise to remove it. you will need a huge belt wrench or a reverse socket in order to keep the engine and pulley from moving so you can crack the bolt. if the transmission is not attached to the engine at this point you may be able to use a crowbar to prevent the flywheel from turning and stop engine rotation that way. goodluck

Remove the serpentine belt and try to rotate the engine by hand. Take the spark plugs out and try to rotate the engine by hand. If it has an automatic tranmission disconnect the flexplate bolts and try to rotate the engine by hand. If no no luck the engine is seized somewhere and will need replaced or overhauled.
