Changed timing chain and need to align to cam with the crang

With Cam Caps loosened, FIRST loosen timing chain tensioner, press it in to loosen tension, Crank using ratchet to TDC (Top Dead Center on crank pully, (to keep from damage to pistons), align Exhaust Cam Timing Mark to mark on #1 Exhaust cam cover, then take up slack between Exhaust & Intake Cams (on top between the cams), Then align the Intake Cam to mark on #1 Cam Cap, "Now" loosen the 17mm bolt to tighten timing chain, rotate engine using rachet two times, reset TDC at the crank, and look at "Cam Timing Marks on both the Exhaust, and Intake Cams. If you did all this correctly the "Timing Marks" should be lined up so TDC,Exhaust, and Intake marks are all the same.

place no 1 piston at TDC compression stroke. There are procedures for the timing of the balance shafts but if it is only the timing chain I will go to that
Align uniquely coloured chain link with intake camshaft sprocket timing mark-- INT--. ( this will be pointing at the 2 o'clock position)
install timing chain and sprocket as an assembly
align first matching coloured chain link crankshaft timing mark (5 o'clock position)
align the second matching coloured chain link with exhaust cam shaft timing mark--EXH ( at the 11 o'clock position
There is a special procedure to reset the balance tensioner and it is different to the timing chain procedure.

To reset cam shaft timing chain tensioner push piston fully and turn clockwise until locked
Once the tensioner has been compressed ensure the distance from end to end is 2.83 inches . If not repeat the resetting process
vehicles 30.000 miles the tensioner is released when the engine is first started . In vehicles over 30.000 miles manually release tensioner by tapping the plunger
Note cam shaft and crank shaft sprockets bolts MUST only be used once. If you want details on the balancer chain procedure then make a comment in the box
use tension wrench and a degree gauge
cam bolts are tensioned to 63 ft lbs + 30 degrees
crank shaft pulley is tensioned to 74 ft lbs + 75 degrees

Here's a link to your timing chain.

By :"specs" I assume you need install position? To index the gears, whne you take it apart, turn the crank pulley 'till the timing mark aligns with the "0" on the timing scale. Don't turn the crankshaft again. When you are ready to install the chain, locate the mark on the crank gear and align the mark on the cam gear so they point to each other. The mark on the crank gear should be at 12 o'clock and the cam gear mark at 6 o'clock. Make sure when you put the cam gear on the cam that the location pin fits into the gear to position it correctly. Jeep recommends that after putting the chain and gears on, you rotate the engine by hand and place the crank mark at 6 o'clock and the cam gear at 3 o'clock, then count the number of pins in the chain (pins, not links) between those two points. There should be 15 pins. If you are rebuilding the engine and have the cylinder removed, it's a good time to check the front crank pulley (some have the outer ring move on the rubber). Put a piece of flat steel across #1 cylinder with a bolt through the steel extending into the bore center. Turn the engine by hand 'till the piston contacts the bolt. Make a mark on the pulley and turn the engine in the opposite direction till contact is again made. Your timing mark on the pulley should be exactly between the two marks you made. If not, make a new mark at that point and use that as your actual TDC reference. If it is radically off, replace the pulley.
When setting up cam position I always use a degree wheel. If you are installing an aftermarket cam
its important to do that. If you're just replacing a stock chain, You will be fine with the method I've outlined.

The 2.2 liter engine uses colored links on the timing chain to align with the marks on the gears. You just have to rotate the engine to where the copper chain link is up on the upper right side of the intake can gear--aligned to the INT diamond on the gear. Then the silver link should be down at about 5 O-Clock on the crankshaft timing mark. The other silver link should then be aligned to the mark on the exhaust cam sprocket. See picture below.

For the 3.0 liter engine, there are marks on the belt that line up with marks on the gears. The book calls out special tools to hold the cam sprockets in alignment while the belt is put on. There is also a special tool to lock the belt onto the crankshaft sprocket. See pictures below.
Please let me know if you have questions.

To Install:

1. Install or connect the following:
   • Timing chain drive sprocket to crankshaft
     1. Rotate the crank so the mark on the sprocket is at the 5 o'clock position
2. Assemble chain to the intake camshaft sprocket alignment copper link to the "INT" diamond timing mark on the camshaft sprocket
   
   NOTE: When lowering the timing chain rotate the assembly 90° to allow the chain to fall between the cylinder block bosses then rotate the assembly back so the camshaft sprocket is facing forward.
   
   
   
3. Lower the assembly through the chain housing opening on top of the cylinder head. Use care to ensure that the chain goes around both sides of the cylinder block bosses NOTE: The crankshaft sprocket timing mark will be at approximately the 5 o'clock position.
   
4. Route chain around crankshaft sprocket and align silver link to the timing mark
   
   NOTE: The camshaft sprocket bolts are not reusable; they are torque-to-yield and must be discarded to prevent premature failure.
   
5. Install or connect the following:
   • Intake camshaft sprocket loosely onto the intake camshaft then install the new camshaft sprocket bolt finger tight NOTE: It is not necessary to align the sprocket-to-camshaft offset notch at this time.
     
   • Adjustable timing chain guide through the opening on top of the cylinder head then install the chain guide bolt; torque to 89 lb-in. (10 Nm)
     
     
     
     
   • Exhaust camshaft sprocket loosely onto the exhaust camshaft with the timing mark on the sprocket aligned with the silver link then install a new camshaft sprocket bolt finger tight
   NOTE: It is not necessary to align the sprocket-to-camshaft offset notch at this time.
   NOTE: The camshaft sprocket bolts are not reusable; they are torque-to-yield and must be discarded to prevent premature failure.
   
6. Align the camshaft sprocket-to-camshaft then tighten the camshaft bolt using the following procedure:
   
   NOTE: Do not rotate either camshaft more than 1/2 turn in either direction with the crankshaft at Top Dead Center (TDC). To do so may cause valve to piston contact resulting in a damaged valve and/or a damaged piston.
   
   • Ensure that the sprocket timing mark is at the 5 o'clock position
   • Rotate the intake camshaft using a 24mm wrench on the flats of the camshaft until the sprocket-to-camshaft alignment notch seats
   • When the sprocket seats on the camshaft tighten the sprocket bolt finger tight
   • Rotate exhaust camshaft using a 24mm wrench on the flats of the camshaft until the sprocket-to-camshaft alignment notch seats
   • When the sprocket seats on the camshaft tighten the sprocket bolt finger tight
7. Verify that all colored links are aligned with the appropriate marks on the camshaft and crankshaft sprockets NOTE: If they are not repeat steps 1C through 4.
   
8. Install the fixed timing chain guide and bolts; torque to 89 lb-in. (10 Nm)
9. Install the fixed timing chain guide bolt access hole plug; torque to 30 lb-ft. (40 Nm)
10. Install upper timing chain guide and bolts; torque to 89 lb-in. (10 Nm) NOTE: Use a 24mm wrench to support the camshaft while applying torque to the camshaft sprocket bolt. Do not torque the camshaft bolts against the timing chain as it may damage the timing chain.
    
11. Torque the intake and exhaust camshaft sprocket bolts; torque as follows:
    • First Pass: 63 lb-ft. (85 Nm)
    • Second Pass: Turn an additional 30° using a torque angle gauge
12. Install the sealing ring and tensioner assembly; torque to 55 lb-ft. (75 Nm)
13. Install or connect the following:
    • Timing chain oil nozzle and bolt; torque to 89 lb-in. (10 Nm)
    • Camshaft cover assembly
    • Engine front cover
    • Negative battery cable; torque to 13 lb-ft. (17 Nm)

In order to time this engine you've got to align the cams with the respective markings on the new belt, this also pertains to the crankshaft pulley. If there are no markings on the belt, the camshaft markings will have a demarkation on the head two which each cam must be aligned. From here I cannot tell you where thes marks are but they are usually at 12:00 or 3:00 plus when you get near the alignment point the cams will feel almost like they are freewheeling for about 3/4- 1 inch in either direction.The crankshaft has to be at TDC or topdead center. this is easily accomplised with a 12 inch ruler laid across the front of the pulley with the long side facing up. This way you can center the mounting bolt and the timing mark at the same time, assuring you of exact center alignment. That's about all I can offer. Thank you, Dana. P.S. please do not turn the engine over with the key until you are certain that all three marks are dead on target. You may however turn it over by hand using a socket of the correct size going clockwise on the crankshaft.

Cylinder #1 set at TDC, compression stroke. Cam marks level with head, aligned with mark on cover, or if unclear where to mark the cam: SET Cam at point where intake valve has just closed and both valves are shut on cyl. #1, cam gear marks should start to appear more clearly to technician, along with corresponding alignment points. This is ballpark. Remember, on clockwise rotation, after cylinder #1 intake valve(s) are shut, the cam will continue to rotate 90 degrees and come to rest at a position in which both exhaust and intake valves are at their maximum lash point. (the most play) Hopefully if you get this close, you will decipher the marks that exist on your Bavarian machine.
