Since it is manufactured with certain specifications to withstand the vibrations, when the durability changes, it doesn’t do its job.The rubber damper can either get softer or harder over time.That can cause the balance ring to slip out of place, and may result in the belt going off-track and damaging all the things it drives (A/C, alternator, water pump, etc.).This is accelerated by the engine overheating or an oil leak.The rubber damper that joins the hub and balance ring can deteriorate over time.Some of the most common problems with harmonic balancers are with the rubber damper. The harmonic balancer absorbs all of that intense vibration and offsets the torsional distortion to protect the crankshaft, and ultimately, the engine.Torsional distortion is a fancy engineering way of saying twisting back and forth.When the engine’s cylinders fire (which happens THOUSANDS of times per minute), it creates a whole heck of a lot of vibration and torsional distortion to the crankshaft.So defending my incessant need to a million questions. I will do as you both suggested first thing tomorrow so trying ask as much as I can now as most folks are working during the day and the responses do not come in until long after it gets too dark to work Not complaining just how it is. My goal would be and is to get the dizzy back to the middle of the holddown slot and the timing be at 15 btdc which should be the 5th timing mark right? Along with making sure the rotor was pointing at the #1 plug. I used a length of coat hanger to make sure the cylinder was at its highest point in the stroke.

cannot check any more times 40 teeth between cam dimples, 43 teeth between drivers size cam and the crank gear dimples. Buy AC Delco - Harmonic Balancer Pulley LS 98-02 Camaro SS Crank Crankshaft LS1 GTO (BAL200) from ICT Billet and browse through a huge selection of Made in. I guess that is why I have been so concerned with doing it wrong. That was the third marker in which I determined TDC. I remove the hold down, pull up the dizzy until it frees from the gear then turn it clockwise one tooth? Just to make sure I understood what you suggested. Just a little nervous about pulling it up, and turning it

I am thinking that it is off a tooth as well. I had not loosened the dizzy at all until after the belt was back on. It was at least 1" to 1.5" past the last timing mark.

When it was in the center of the holddown slot it was way off in terms of the marks. it will go way over but will not retard(is that the correct term) back to 0 tdc. Like shouldnt I be able toget the timing marks to line up at 0 degrees tdc? like why can I not move the distributor enough to bring it back. Please any immediate help on this would be appreciated.

I do not want to go any further putting things back together in case I have to redo it all again. I know the engine should be 15 degrees (is it 18?) btdc. the engine seems to be idling and revving up nice however it bothers me that I cannot adjust the timing any further back to get to 0 tdc. so I guess that would be the 5th line from the left going clockwise. I was able to turn the distributor counter clock wise and got the timing mark on the balancer to line up with the 3rd mark from the right hand side. With that said when I pulled out the timing light the lines are WAY off. So seems that I have it as correct as I could get. Checked four more times 40 teeth between cam sprocket dimples and 43 teeth between drivers side cam and the crank gear dimple. Ironically when I went out today guess the engine stopped close to tdc on cylinder 1 as the lines actually lined back up. You may also notice worn belt edges or squeaking. If your balancer fails, the first sign will be engine vibration. It may also be attached to a crankshaft pulley to run the accessory belt drive. So very little chance that I did it wrong. The harmonic balancer is attached to the end of the crankshaft and absorbs and dampens engine vibration. I know without any doubt that when I switched out the balancer pulley I put them back on exactly the way they came of including matching the keyway. Ok the lower timing belt cover is back on. Ok I am going to put this here instead of starting another thread.
