The easiest way and the best way to prevent damage is to remove the tire, splash shield and accessory belts then remove the harmonic balancer bolt using the special holding tool DenLors 648796. The balancer or crank pulley will then slide off fairly easy, then reverse this procedure to install the replacement pulley.
Ok, regardless if you are working on the 1.5 or the 1.6 it's a pain in the you know what. The bolt is on very very tight and requires a special tool for ease that is made just for Honda harmonic balancers It holds the balancer in place while you turn the bolt use a large steel pipe or breaker bar with an IMPACT SHALLOW 6 point socket and break it loose. I've only seen a few impact wrench guns that could turn this over torqued bolt. Just DONT break the bolt.. You will be upset...$$$$$
You first need to lift the car off the ground like your changing the tire(get it on a cherry picker if you can for easier access). Take the tire off, loosen the tensioner on the alternator, and get the belt off. Take a 11/16"ths shallow 1/2" socket and a 14" or larger steel pipe for torque because this bolt is very very tight and can easily break your tool. There are a few impact guns to take it off.
According to my manual you can push a large screw driver in a hole near where the speedo cable connects to the gear box to lock the flywheel. I found I had to remove a small bolt to get the hole large enough to fit the screw driver in. A small piece of casing broke and it became very easy to lock the flywheel. The bolt came undone with a socket and a 30 in bar. I don't think the missing casing is going to make any difference.
You need a harmonic balancer puller, and a 1/2 in drive inpact wrench.
To install a harmonic balancer on a Buick Riviera, first ensure the engine is at TDC (Top Dead Center) on the compression stroke for the first cylinder. Align the keyway on the balancer with the key in the crankshaft, then slide the balancer onto the crankshaft. Use a harmonic balancer installation tool to press it on evenly and avoid damaging the crankshaft. Finally, torque the retaining bolt to the manufacturer's specified settings.
behind the harmonic balancer (crank pulley). you need a special puller, and 1/2 drive impact wrench to change it.
The flywheel has to be held in place by a holding tool, Remove the mounting bolt, then use a balancer remover to pull the harmonic balancer.
Just put the cam bolt back in and tighten it down, it will go back in easy
I tried to change the harmonic balancer of my biuck lesabre 1994, but i can't remove the old one, the bold in the center is very , very tight and i don't know the type of screw, right or left turn.
it is behind the harmonic balancer.
You need an oscilloscope. I use a vantage, it costs like $3K. now the crank sensor only cost like $40, but have to remove the harmonic balancer to change it. Now their is the delimna mechanics always face.
Behind the harmonic balancer.
To replace the harmonic balancer on a 1994 Buick Regal, start by disconnecting the negative battery cable and removing any components obstructing access, such as the serpentine belt and crankshaft pulley. Use a harmonic balancer puller to carefully remove the old balancer from the crankshaft. Install the new harmonic balancer by aligning it properly and using a torque wrench to tighten it to the manufacturer's specifications. Finally, reassemble any components you removed and reconnect the battery.
take off your harmonic balancer the answer is behind
