Help me.. Once Fan/Shroud has been removed, what is the best way to remove the harmonic..? It simply spins on me when usinga spanner. I have tried to put preasure on the tensioner but it still spins on me..
Desperate, Please help..

There are a couple of ways to do it but you have to be careful.
1. Using the correct size spanner with a hammer. Use the hammer to give the spanner a sharp blow. This may loosen the bolt.
2. Now this is a fairly dangerous way to do it if done incorrectly. Get a socket the right size for the bolt. Now you will need either a long breaker bar or a shorter one with a bit of pipe on it. It has to be long enough for the end of it to go under the chassis rail on the drivers side of the car. Now get the socket and breaker bar into position with the end of the bar under the drivers side chassis rail making sure it is as close to the rail as possible. Now make sure the car is in neutral and the plug leads are off. Now just hit the key quickly and let it go this should loosen it off.
NOTE - IF YOU ARE NOT CONFIDENT WITH SPANNERS OR MECHANICS THIS WAY IS NOT RECOMMENDED
3. If the car is a manual apply the handbrake fully select forth gear and chock the rear wheels. This will not allow the crankshaft to turn making it fairly easy to undo the bolt.
4. If the car is an auto gain access to the flex plate(if not sure what this is it is the plate that basically couples the engine with the transmission) by removing the starter. Now place a suitable bar/screwdriver between the cylinder block and the flex plate teeth. This should stop the crankshaft turning.
5. If you have access to an rattle gun(pneumatic impact gun) this also does quite a nice job
I personally would recommend either number three or four to do this safely.
Good luck. Anything need to be clarified please dont hesitate to ask

The *CORRECT* way to do it is to drop the gearbox out and get a proper tool which locks onto the flywheel and can be locked to prevent the crank spinning.
However, putting the car in gear (if it's a manual), with the handbrake on should lock it. If it's an auto, it's a bit tougher.
Short sharp bursts on a rattle gun MIGHT do it, otherwise, use number 2 at your own risk. |

I could be wrong, and Im to drunk to be bothered to check. But iirc on your harmonic balancer there is a little hole on the front, jam something in there to act as a counter lever and take to it with a rattle gun.
Failing that, this *might* work but it also might take a chunk of the block with it....
You will need: 1x Engine with balancer to be removed, Appropriate tools to remove it with, 1x Hammer, Several x various sized and angled wedges (made from wood or other reasonably tough, yet soft substance)
Work out which direction to undo the balancer, get wedges, insert behind balancer going the opposite direction (so when it spins they jam in tighter) bash with hammer to make sure they are in firm, undo.
*Note: Ive never done, or seen above method but have been told it works. |
Don't mind me, Ive heard a lot, seen a bit, done some of it . That and Im probably not quite sober. |

| ^^^That method sounds just as dangerous (but reliable) as using the chassis rail to undo the bolt. It would probably work okay, but be damn risky. |

| i have recently taked off a harmonic ballancer off my vn calais i just wedged a tyre wrench in the spokes of the harmonic balancer and undone the bolt but you need a pulley puller 2 get them off and also best to replace the crank angle sensor as they tend to break sometiomes while removing |

ok welcome 2 the club but jamming sh#t in the harm bal is not the brightest idea of cause u r bound to break stuff the easiest way is 2 jak the front end up and take the inspection cover of the gearbox.U will need 2 people 2 do this but I did it on my own (wat a prik if you lazy like me) now get person 1 2 turn the harm bal until u can c the torque converter bolts if u put a long and thich flatblade or even a flip's screw diver in between the converter bolts, person 1 should b able 2 crak the harmonic bolt then.....person 2 just has 2 get a bit dirty I found this 2 b the most effective way if u are on a budget and cant get the right tools!!! remember the more reach on your breaker bar the easier it will b 2 crak !!!!!!!!!
happy crakin ;) |

Well.. What an exercise..
After breaking a socket, Then a breaker bar, it didn't seem like it would budge.. Took it to a mechanic who spent a number of hours trying to undo it. He failed and recomended another with BIGGER tools..
Took the 2nd mechanic 2.5 hours but got it done.. How......?
20 mins with an oxy torch heating the bolt. To the point that the rubber on the balance just started to melt. A couple of wacks with the 5lb hammer then the 3/4in rattle gun and it finally came undone.
Car's back and working ok now but what and excersise this has been..
Thanks for all the advice everyone..... |

Just a question, Was the front engine oil seal replaced after the heating episode??
If not it probably should have been because the oxy would have heated the sealing surface and either melted the seal slightly or made it hard and you will more than likely have trouble's with it leaking now until you replace it. Just keep an eye on it, it may not have gotten that hot but there is always a chance. |
