How do you change the harmonic balancer on a 1992 Honda Civic?

Answer 1

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.
