The camshaft is situated in the cylinder head( top part of engine) and the crank shaft is located in the cylinder block (the lower part of the engine) to replace either of these components are expensive to replace req the engine to be stripped down

Where is the cam shaft of a 2001 grand cherokee limited located


If your talking about the actual camshaft and not the sensor, with ohv engine, the camshaft is inside engine block. It is usually driven with a timing chain off the crankshaft gear.

Can you tell me how camshaft position sensor work in engine.


Crankshaft and camshaft sensors monitor a tone ring inside the engine that are part of the camshaft or crankshaft. This sends a signal to the computer so it knows exactly what position each of the components are in so it can tell the ignition and fuel system what to do at any given micro-second, at any rpm.

On a 99 Amigo 3.2 if u have the cylinder heads off how do u make sure they areis in time with the engine also how do u get the engine in time


You probably need a manual with a picture. You need to find a mark on the crankshaft that aligns with a mark on the camshaft pulley. Usually you will put the mark on the crankshaft pulley at top dead center and then the camshaft pulley has to be in the exact spot so the timing belt will keep the relationship between camshaft and crankshaft. You can get free manuals at the library and maybe autozone has repair guides for your car. But bottom line...the timing is at theose marks on the crankshaft and camshaft and they have to be synchronized

Check engine flashing engine misfire jeep cherokee Engine codes show misfire on 1-4 cylinder check engine light flashing at 75mph AC running


1st, replace your spark plugs(for gasoline engine) or heater plugs (for diesel engines)

if this does not work, have a mechanic check the timing of your engine. Engine timing is checked in the distributor, camshaft, and crankshaft.

Timing marks trooper 1985 mod dlx turbo diesel


Refer to Figures 1,2,3,4 when performing 17-step timing procedure for 1981-1985 Diesel Engines.

Fig 1. Injection pump and camshaft alignment marks - Diesel engine.

Fig 2. Removing the timing belt holder - Diesel engine.

archaeology_67.jpg

Fig 3. Injection pump alignment marks - Diesel engine.

archaeology_68.jpg

Fig 4. Tensioiner Pulley Bolt Sequence - Diesel engine.

archaeology_69.jpg

Procedure - Timing Belt replacement.

1. Disconnect the negative battery cable. Drain the cooling system.

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.

2. Remove the timing belt cover. Remove the injection pump sprocket flange.

3. Using a prybar, remove the tension spring from the timing belt tensioner.

When removing the tension spring, avoid using excessive force for the spring may become distorted.

4. Remove the tensioner pulley bolt and the pulley.

5. Remove the timing belt and discard it.

To install:

6. Rotate the crankshaft to bring the No. 1 piston to TDC of the compression stroke.

7. Align the timing marks on the injection pump sprocket with the camshaft sprocket; the marks must be facing each other.

8. Using a new timing belt, install it in the following sequence: crankshaft sprocket, camshaft sprocket and the injection pump sprocket; the slack must be between the injection pump and camshaft sprockets.

9. Install the tension center and the tension pulley so the end of the tension center is fitted against both pins on the timing pulley housing.

10. Hand tighten the nut so the tension pulley can be rotated freely.

11. Install the tension spring and semi-tighten the pulley nut to 22-36 ft. lbs. (30-48 Nm).

12. Rotate the crankshaft 2 full turns clockwise to seat the belt and further turn the crankshaft 90° beyond TDC to settle the injection pump.

13. Loosen the tension pulley nut to take up the timing belt slack. Tighten the tension pulley nut to 79-94 ft. lbs. (108-128 Nm).

14. Install the injection pump sprocket flange; the hole in the outer circumference of the flange should be aligned with the triangular timing mark on the injection pump sprocket.

15. Rotate the crankshaft 2 full turns clockwise to bring the No. 1 piston to TDC of the compression stroke. Make sure the triangular timing mark on the timing sprocket is aligned with the hole in the flange, then, measure the timing belt tension; it should be 33-55 lbs.

16. Install the timing belt cover.

17. Connect the negative battery cable.

Hi, noticed a post of yours rear cambelt replacement on an a4 1.9 tdi ajm year 2000. Would be very grateful for any instructions. The car is stripped down ready for cambelt removing. Stuck on lining up...


Hi, I have pasted instructions below from autozone.com. The instructions call for the use of special tools. You can improvise with alternate tools, but please make sure your timing is right before closing the cover. Please let me know if you have questions, and thanks for using FixYa.

1.9L Diesel Engine
Some special tools are required to perform this procedure properly. A flat bar, VW tool 2065A is used to secure the camshaft in position. A pin, VW tool 2064 is used to fix the pump position while the timing belt is removed. The camshaft and pump work against spring pressure and will move out of position when the timing belt is removed. It is not difficult to find substitutes but do not remove the timing belt without these tools.

WARNING Do not turn the engine or camshaft with the timing belt removed. The pistons will contact the valves and cause internal engine damage.
  1. Disconnect the negative battery cable and remove the accessory drive belts, crankshaft pulley and the timing belt cover(s). Remove the camshaft cover and rubber plug at the back end of the camshaft.
  2. Temporarily reinstall the crankshaft pulley bolt and turn the crankshaft to Top Dead Center (TDC) of No. 1 piston. The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head.
  3. With the engine at TDC, insert the bar into the slot at the back of the camshaft. The bar rests on the cylinder head to will hold the camshaft in position.
  4. Insert the pin into the injection pump drive sprocket to hold the pump in position.
  5. Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt. Slide the timing belt from the sprockets.

    jturcotte_1821.gif

    Fig. Locking the injection pump with the VW tool as shown-Volkswagen 1.9L Diesel engines


To install:
  1. Install the new timing belt and adjust the tension so the belt can be twisted 45 degrees at the halfway point between the camshaft and pump sprockets. Tighten the tensioner nut to 33 ft. lbs. (45 Nm).
  2. Remove the holding tools.
  3. Turn the engine 2 full revolutions to return to TDC for the No. 1 cylinder. Recheck belt tension and timing mark alignment, readjust as required.
  4. Install the belt cover and accessory drive belts.
    NOTE If the belt is too tight, there will be a growling noise that rises and falls with engine speed.
