Truth Time...harmonic Balancer

Okay guys. In another post, I asked if the rubber ring that's in the harmonic balancer was any good. Truth be told, I went over that son of with the angle grinder with a cup brush on. So with this new information what do you guys think?

On another note, I did some searching on the interwebs and found a Dayco brand harmonic balancer that I'm taking a chance on coming in this Thursday.

In the mean time, I have taken the original HB and I have the rubber ring soaking in this solution that keeps it protected and moisturized. Pics attached for your viewing.

 

Unless you are seeing something up close in person that alarms you about the condition of the rubber I believe that your current balance is acceptable, the wire wheel cup doesn't appear to have inflicted any severe damage.

I see nothing wrong with that HB.

 

No expert here but it’s my understanding that harmonic balancers can wear out and when they do can cause issues that are hard to diagnose. When I was building my engine the “Old Timer” that was helping me demanded I buy a new one which at the time only cost about 60 bucks. I would suggest if the new one you have ordered is correct and is a fair price to install it. Just my opinion, good luck.

 

You could install the current balancer and roll the engine to number 1 top dead center then look at the timing marks to verify that it has not spun out of the proper indexing.

You could position the outside "ring" so it is elevated and push real hard with the palm of your hand on the inside "ring" to see if the two rings move apart.

You could take a prick punch and make 2 witness marks that align the two rings to reference later to see if anything has moved out of spec. Maybe do the same on the Dayco unit.

When the Dayco unit arrives lay it on top of the original and compare the keyway and timing marks.

Just in case...so there are no hard feelings, the obsessive compulsive remark i made was my attempt at humor.
Keep the OCD under control or the next thing you know you will be aligning electrical outlet cover screws

Outlet screws go vertical

 

I second that.

 

I've had the outer ring on a balancer "walk" on another engine. It was driving me nuts when the timing mark and TDC didn't correspond. As long as these marks still line up, and the ring isn't loose, its still likely good. If you have a fresh balancer, that is good piece-of-mind! Keep that old one, as it still looks good.

TRUE.................Fact is old balancer technology is simply based on a rubber band surrounded by a hub........which is designed to cancel engine harmonics coming from the crankshaft , rotating assembly and clutch...in an attempt to help prevent crank breakage , bearing wear and enhance seal life....................Rubber as we all know is subject to deterioration from a number of factors such as use, age, oil , chemicals , weather and the list goes on........anyone that thinks they can look at a balancer and tell whether it's good or not has an exceptional talent........There are people that can spin it up and check it......but I doubt that would be cost effective vs just changing it!

I believe you have already bought a replacement ? Install it and enjoy your vehicle.
