Need timing chain marks for 02 dodge 4.7


There are no " Marks" to line up. There is a h whole set of alignments you have to do.
The engine needs to be at TDC. there are colored links on both the secondary timing chains that align with A. the holes on the Idler sprocket, 4 O'clock & 8 O'clock. and B. with the cam sprockets having the V8 at the top of both cams the colored chain link aligns with the R or L of the corresponding Right or Left cam. This all needs to be done in proper order at maintain proper valve timing. failure to do so will end up with possible valve to piston damage. It is better to get the book on the truck for $25.00 rather than do hundreds in damage. You can even get DIY subscriptions online delivered right to your computer instantly for about $20.00
Sorry I type way too slow and would take me all night to tell you exactly how to do it.
But if you are engine savvy and have good knowledge as to slack on the timing chain goes on the return side of the chain to cam from crank, (tensioner side) reset your tensioner & pin before you install the chain tensioner. you can do it.

Does the timing chain on a 2000 s type jaguar 4 0 need to be set at top dead center


Replacing the timing chains on this engine is no cake walk and I would not recommend it to anyone unless they are very experienced technicians.
There is a specialty Ford tool, part number 303-645, that is used to set the crankshaft while the timing chain is being replaced. You will need another Ford tool, part number 303-530, which is used to lock the cam shafts in place in order to prevent rotation.
There are other tools needed, but they are for other aspects of the same job.
You can not just set the engine to TDC and work with it from there because of the VVT system and general nature of the engine.
Please let me know if I can be of further assistance.

Jaguar xj8 wont start after replacing timing chans


I'm sorry to tell you this, but you are going to have to start from ground zero. Take your timing cover back off. Ensure that your NO. 1 Piston is at TDC (Top Dead Center) and that your cam is aligned properly. Once you've done that, put the timing chain back on and bolt everything back together. If your timing is off a little bit, your engine won't run. If your timing is off alot, then your valves will hit the piston heads and cause ALOT of damage.

Jaguar X-Type cam belt


These are chain driven. The only issue I have seen with these are the chain tensioners breaking. Generaly with chain driven engines, the chain will last the life of the vehicle, unless something like the tensioner or guide brakes. If it does break repairs can be fairly expensive.

Item Part Number Description 1 — 40 Timing Chain/Belt Teeth 2 6256 Camshaft Sprocket , Front 3 — 43 Timing Chain/Belt Teeth 4 6306 Crankshaft Sprocket 5 6268 Timing Chain/Belt 6 6256 Camshaft Sprocket , Rear
Removal
  1. Drain the cooling system. Refer to Section 03-03 for the procedure.
  1. Disconnect the battery ground cable (14301) .
  1. Remove the generator drive belt, water pump and power steering pump drive belt, and the A/C compressor drive belt (if equipped). Refer to Section 03-05 for the removal procedure.
  1. If equipped, remove the three A/C compressor drive belt idler pulley bolts and the A/C compressor drive belt idler pulley.
  1. Remove the upper radiator hose bracket bolt.
  1. Loosen the two upper radiator hose clamps and remove the radiator hose bracket bolt. Remove the upper radiator hose (8260) and the upper radiator hose bracket from the vehicle.
  1. Remove the water bypass hose (8597) from between the thermostat housing and the water hose connection (8592) .
  1. Remove the main wiring harness from the upper engine front cover (6019) .
  1. Remove the eight upper engine front cover bolts and the upper engine front cover .
  1. Raise and support the vehicle.
  1. Remove the RH front wheel and tire assembly.
  1. Remove the four RH outer engine and transmission splash shield bolts and two screws and remove the RH outer engine and transmission splash shield (6775) .
  1. Use Strap Wrench 303-D055 (D85L-6000-A) or equivalent to hold the water pump pulley (8509) while removing the four water pump pulley bolts.
  1. Remove the water pump pulley from the water pump (8501) .
  1. Remove the crankshaft pulley (6312) . Refer to the procedure in this section.
  1. Remove the five lower engine front cover bolts and the lower engine front cover .
  2. Ensure that the timing marks between the crankshaft sprocket (6306) and the oil pump housing line up.
  3. NOTE: The directional arrow is necessary to ensure that the timing chain/belt (6268) can be reinstalled in the same direction.
  4. Loosen the timing chain/belt tensioner nut.
  5. Remove the timing chain/belt .

  6. Installation
    NOTE: Ensure that the timing marks on the camshaft sprockets (6256) and the seal plate are properly aligned. Ensure that the timing marks on the crankshaft sprocket and the oil pump housing are still aligned. NOTE: A new timing chain/belt has three white timing marks that indicate the correct timing positions of the camshafts (6250) and the crankshaft (6303) . These marks will help ensure that the engine (6007) is timed properly. When the engine is properly timed each white timing mark on the timing chain/belt will be aligned with the corresponding camshaft and crankshaft timing mark on the sprocket. Because the white timing marks are not evenly spaced you will need to refer to the following illustration for proper timing chain/belt placement. There should be 40 timing belt teeth between the timing marks of the front and rear camshaft sprockets and 43 teeth between the timing mark on the front camshaft sprocket and the timing mark on the crankshaft sprocket .

    NOTE: Verify that the camshaft timing marks are aligned with the timing marks on the seal plate, and that the crankshaft sprocket timing mark is aligned with the timing mark on the oil pump (6600) .

    Install the timing chain/belt starting at the crankshaft sprocket and moving around to the camshaft sprocket following a counterclockwise path. Do not allow any slack in the timing chain/belt between the timing sprockets. After all of the timing marks are matched up with the timing chain/belt installed, slip the timing chain/belt onto the timing chain/belt tensioner .
