Harmonic Balancer Removal
 

Can the harmonic balancer be remove with the motor in the car?
Doesn't look like a lot of room.

far as I know it needs to come out/might get one of the pro's like Henderson performance to chip in/mine came out to change it

Yes. I did it on my customer's car. Although it was on a 2 post lift which helped a lot. I can't imagine doing it in a garage on your back.

I'll give it a shot then. My car is on my 4 post lift in the garage. Thanks

The p/s fluid cooler will need to be unbolted and just let it hang. The rack and pinion will need to be unbolted and lifted up as much as it can to access the harmonic bolt and install a puller. It's been a few months since I did it and I believe the engine has to be lifted to clear the cross member as the harmonic balancer pulled forward. To reinstall, my installer was not long enough to reach the thread on the crankshaft so I had to modify the crank bolt. PM me your cell no. and I'll text you pics.

This is what I have :p

1. Harmonic Balancer.
The Harmonic balancer is initially installed using a standard harmonic balancer bolt welded to a longer threaded shaft (the Harmonic Balancer bolt alone is not long enough to initially set the Harmonic Balancer). Use Red Loctite (262) and torque the Harmonic Balancer bolt to 148 ft-lbs (block of wood jammed into the crankshaft area with oil pan removed). Be carefull the timing chains are not locked on the timing chain idler sprocket preventing the crankshaft from turning.

My car is actually in my shop on the lift, working on it for the Mojave Mile run on April. I looked at the harmonic balancer to refresh my memory and the engine does not need to come up. The thread pitch on the crank bolt is a fine thread and none of the adapter in my installer kit fits. I id not have an extra crank bolt to weld so I had to modify the original bolt to be able to reuse.

Dynomite, I text you the pictures.

BennieC says he drilled and tapped the original crank bolt with a 7/16-20 threaded tap. He did not want to mess up an original crank bolt by welding a threaded extension just for installation of Harmonic Balancer. I am thinking the Harmonic Balancer Bolt tensile area may be reduced somewhat by internal threads if such threads extend below the flange of the bolt and such bolt is used in the final installation of the Harmonic Balancer.

BennieC's Harmonic Balancer Installation tool is a lot nicer than my welded variant :p

In case you guys are wondering why I included a picture of that 1/2 inch impact gun. That gun is mainly designed for crack bolt removal/install since the regular sized impact gun will not fit between harmonic balancer and the radiator on most cars, the ZR-1 included.

Re: Harmonic Balancer Removal
 

What size and pitch is the lt5 harmonic bolt? Or where can I purchase one of these installation tool? I'm finishing on the motor and will need to install damper back on.


Thanks
