Important: The nose of the crankshaft should be recessed 2. An impact wrench will almost always remove the crank bolt without needing to hold the engine from turning. Two numbers you need to check here. Removing the balancer is usually considered to be more difficult than installing it, but failing to properly install the balancer can be even more destructive than running the engine with an old one. This will relieve the pressure off the keyway adjustment bolt so you can unscrew it and… Yes an 89 350 will bolt up to original Vortec heads.
What are my options here? I just picked up a 99 Silverado 5. Would you need to drop it out of the van? Now look behind the harmonic balancer at the passenge side of the timing chain cover and you will see it. Note: has torque values for various engines. The harmonic balancer slides onto the tip of the crankshaft. Unless the shoes are very worn, you will have to back them in to be able to remove the rotor. Neighbors heard me recite every swear word in the book on that event. Also most dampers have an elastomeric band that separated the inner hub from the outer inertia ring.
Now, on your way home from having the machine shop hone the hub of your damper, stop by and pick up some dry ice. Some guys might say, I have no business attacking a challenge like a cam swap with no prior experience at all. Visually inspect the crank snout closely for burrs or nicks that might interfere with the smooth installation of the damper. If one says G-80, it has it. Remove the dry ice baggie from the crank snout. The only thing in the way would be a cross member from the suspension.
The balancer gave a steady hard pull all the way off and the used replacement pushed on smooth steady and tight also. Once it starts, most of the time it will come off the rest of the way easily. Prior to 1986 all intake manifolds for a sbc had 12 bolts. Removing the balancer is usually considered to be more difficult than installing it, but failing to properly install the balancer can be even more destructive than running the engine with an old one. Edited April 21, 2017 by Jsdirt Yeah I have to agree on that.
The harmonic balancer attaches to the end of the crankshaft with a single bolt. If anyone is curious as to why I was in my 5. On some vehicles you can get at the harmonic balancer from underneath the car or truck. Thank you Proform and Jegs. Sorry to ramble on but this whole repair was ridiculous and in my eyes an engineering disaster. Swapped said balancer with used one and still same amount of wobble and squeal.
Either one will work and will give the machine shop a half thousandth to play with. This is so the torsional vibrations of the crankshaft generated by the power pulses of the engine can be transmitted to- and absorbed or dissipated by- the harmonic balancer. You want to make sure the key is short enough off the crank surface to not interfere with the roof of the keyway in the damper to prevent the damper from being installed at all. Initial quick look after test drive I noticed Orange silicone on left bank exh manifold. They sure don't build 'em like they used to. These 12 bolts all secured the intake to the head at the same angle. The following is my reply: Normally, I wouldn't hone one either, knowing that the intended purpose of the damper is to transfer harmonics from the crankshaft to the inertia ring on the damper and also knowing that if the fit on the crank snout is too loose, that these harmonics will not be transferred and could result in a cracked crankshaft.
I happen to have a lathe my little shop, so i chucked it up and old balancer runs true. I think what the contributor is saying is that most of these aftermarket offshore dampers are bored about one and a half thousandths 0. Apply presure to the keyway by screwing the balljoint spacer as if you were tightening it. Position the larger end of the installer against the front of the balancer. A simple but very useful tool at a great price.
Another contributor said there was no way he would hone a damper. I might pull it and mic it. For now, I took the cheap way out and bought a Range device off eBay. On some engines just the engine compression and the friction from the belt-driven accessories will allow the bolt to be removed. I bought this installation tool mostly due to the low price and very seldom needing one.
This means removing it with the engine in the vehicle can be difficult. Truck ran fine, I bought truck. The way things are built today, by the time everything in there rusts enough to become a problem, the vehicle will have been in the scrap heap long, long before. Thrust bearing and protective washer allows the drive nut to rotate freely so the balancer is pressed on smoothly and evenly. Torque the pulley and crankshaft bolts to spec. The wood is used to insulate the damper inner hub from the hammer blows. Heating the damper in 200º F hot water for 15 minutes will cause it to expand a bit.
