Remove belts, remove four bolts in front pulley to separate then remove big nut in center holding harmonic balancer pry off balancer, it is tapered, sometimes you need a hammer to knock it loose, then refit, don't loose keyway, job is easy and no special tools or settings

1997 Jaguar XJ6-L. Harmonic balance removal. There are not four bolts, you have the wrong car.
Here's how you do it. Did it in 2.25 hours with a couple of buddies while drinking beer.
Remove hood, 6 bolts no biggie.
Remove fan shroud, two bolts and and electrical connection, no biggie
Remove belts. Here's how
alternator belt - loosen the nut at the base of the threaded tension rod(13mm), the bolt on top of the alternator tensioner bracket(10mm), the lower alt. Mount bolt/nut combo(17mm on both ends), and the nut on the inner side of the threaded rod(14mm). Then with your 14mm wrench tighten the nut on the outside of the tensioning rod to release tension on the belt. Then reverse to reinstall new belt.
The a/c belt is simpler,
loosen the bolt in the middle of the tensioner, then with a 1/4" wrench turn the threaded tensioning rod.
Memory fails as to which direction to turn it, but it will become apparent.
You will need: WD 40
-10mm deep socket
-13mm deep socket
Next take a 1.375 socket, (a 33 mm or 34mm is preferred but didn't have one) with a large breaker bar, put on the concrete(making sure you have it in the correct direction to loosen the 1 big bolt, have someone bump the ignition.I'm talking about bump, not start the car) All your doing is using the the engine to loosen the bolt.
Next use a pulley puller, it slides almost out but you still need a pry bar and possible hammer, to get the balancer out. ( I didn't need a hammer just pry bar) there is a little wedge-key you must keep track of.
Slide right off, put new balancer in with key-wedge in the correct spot, take the 1.375 socket and tighten that bolt up with all your might, ( I weigh 250 lbs).
Put belts back on, check to see if everything is running correctly(for just a few seconds don't want the radiator to get to hot, put fan shroud back on.
Pout hood back on, could use three people, one on the left, another on the right, one replacing the bolts, adjust hood as the bolt holes are over sized allowing is bolt movement.
Crank it up your done, and saved yourself $1550 in labor.
